Paphiopedilum rohmanii Cavestro & O. GrussEine neue Art der Gattung Paphiopedilum aus der Sektion Barbata (Kraenzlin) V.A. Albert & Börge Pett aus Nord-Sumatra, Indonesien


Summary: A new species from northern Sumatra is described as Paphiopedilum rohmanii Cavestro & O. Gruss. It is a member of the section Barbata and closely related to Paph. tonsum.

EinführungDieses Jahr wurden einige neue Ar-ten der Gattung Paphiopedilum aus Indonesien einschließlich Java, Su-matra und Sulawesi beschrieben. Im März 2017 beschrieb einer der Autoren zusammen N. Bougourd Paph. agu-sii, eine neue Art aus dem Zentrum Ja-vas (Cavestro, 2017). Aus der Provinz Aceh im Norden Sumatras wurden erst kürzlich 4 neue Arten beschrieben. Ei-ne der Arten, als Paph. dodyanum be-nannt, gehört zur Sektion Cochlope-talum (Cavestro, 2017). Die anderen drei Arten, Paph. lunatum, Paph. bun-gebelangi und Paph. zulhermanianum Cavestro, sind Teil der Sektion Bar-bata V.A. Albert & Börge Pett. Sie wurden von D. Metusala (2017) und W. Cavestro (2017) beschrieben.In diesem Artikel soll eine weitere neue Art der Gattung Paphiopedilum vorge-stellt und offi ziell als Paphiopedilum rohmanii beschrieben werden. Der Na-me bezieht sich auf den Namen des Entdeckers dieser neuen Art, Rohman Ikhwan. Die Art gehört ebenfalls zur Sektion Barbata. Sie stammt nach un-seren Informationen aus dem Norden Sumatras, der Provinz Aceh Tengah. Dieses neue Paphiopedilum hat eine weiße Fahne, die hell purpurn über-haucht ist und braun-purpurne Adern hat. Die Petalen sind mehr oder min-der herabgebogen, grün geadert und hellbraun gefl eckt. Die hellbraune Lip-pe ist braun geadert. Das weißgrun-dige halbmondförmige Staminodium ist in der Mitte grün netzartig geadert. Diese Kennzeichen unterscheiden sie von allen anderen Arten der Sektion

Barbata (Kraenzlin) V.A. Albert & Börge Pett.Auf Sumatra umfasst diese Sekti-on Paph. barbatum (Lindl.) Pfi tzer, Paph. bullenianum (Rchb.f.) Pfi tzer,Paph. javanicum (Reinw. ex. Lindley) Pfi tzer, Paph. superbiens (Rchb.f.) Stein, Paph. tonsum (Rchb.f.) Stein und zudem die neuen, gerade ent-deckten Paphiopedilum-Arten Paph. bungebelangi Metusala, Paph. luna-tum Metusala und P. zulhermania-num Cavestro. Paph. bungebelangi und P. lunatum wachsen in der Provinz

Aceh, Paph. zulhermanianum stammt aus dem Westen von Sumatra. Kei-ne dieser Arten ist dem neuen Paph. rohmanii ähnlich. Die genaue Unter-suchung zeigt, dass die am nächsten verwandte Art das Paph. tonsum ist. Zudem zeigt auch das Paph. barbatum eine gewisse Ähnlichkeit.

Paphiopedilum rohmanii Caves-tro & O. Gruss, sp.nov. ist dem Pa-phiopedilum tonsum (Rchb.f.) Stein, ähnlich, unterscheidet sich aber durch die herabgebogenen Petalen, welche zur Spitze hin verdreht sind, durch die stärker braun gefl eckten Petalen und das halbmondförmige (nicht nieren-förmige), im Zentrum grün netzförmig geaderte Staminodium.

Etymologie: Benannt nach Rohman Ikhwan, dem Besitzer der Gärtnerei Rohman Orchids in Aceh, Sumatra (In-donesien).

BeschreibungEine terrestrisch wachsende Pfl an-ze mit einem, zwei oder mehr Trie-ben. Blätter 4 – 5, schmal länglich bis länglich elliptisch, stumpf oder drei-zähnig an der Spitze, 14 – 21 cm lang und 2,5 – 2,8 cm breit, grün, grün ge-ädert und dunkelgrün marmoriert. Infl oreszenz einblütig; Blütenstand 15 – 24 cm lang, purpurn und feinfl au-mig behaart; Brakteen oval-elliptisch, stumpf, 1 – 1,3 cm lang, grün, purpurn gefl eckt. Blüten 9 – 11 cm im Durch-messser; dorsales Sepalum (Fahne) weiß, purpurn eingefärbt, zur Spitze weiß, braun purpurn geädert; Synse-palum weiß, purpurn geädert; Peta-len weiß, grün eingefärbt in der Mitte und am oberen Rand, grün bis grün-purpurn gestreift, hellbraun gefl eckt; Seitenlappen der Lippe blassrosa bis hellbraun, Mittellappen (Schuh) blass-braun und braun geädert, zur Spit-ze hin blassgrün; Staminodium blass-grün und grün netzartig geädert im Zentrum.Dorsales Sepalum (Fahne) breit oval, Ränder gewellt und bewimpert, 4,5 cm lang und 4,5 breit. Synsepalum ellip-tisch oval, konkav, stumpf, 3 cm lang und 1,6 cm breit. Petalen mehr oder we-niger herabgebogen, elliptisch läng -lich, stumpf, zur Spitze hin ver-

dreht, bewimpert, 5 – 5,5 cm lang und 1,7 – 2 cm breit. Lippe sackförmig, sich zur Spitze hin verjüngend, 4,4 – 4,8 cm lang und 2 – 2,5 cm breit; Seiten-lappen einwärts geschlagen. Stami-nodium halbmondförmig, 10 mm lang und 7 mm breit, mit 2 apikalen seit-lichen kurzen Zähnen, welche etwas nach innen gebogen und stumpf sind.Durch ihre Blüte und die nach un-ten gebogenen Petalen erinnert diese neue Art augenscheinlich an Paph. cal-losum (Rchb.f.) Stein, das in Kambod-scha, Thailand und Laos vorkommt. Bei den Arten von Sumatra erinnert das Paph. rohmanii an Paph. barba-tum und Paph. tonsum. Paph. barba-tum wurde auf der Malayischen Halb-insel gefunden, Paph. tonsum im Nor-den und im Zentrum von Sumatra. Die-se zwei Arten sind zwar räumlich nä-her zu Paph. rohmanii, aber die Blü-te von Paph. barbatum unterscheidet sich doch recht deutlich. Paph. bar-batum hat nur etwas herabgebogene Petalen ohne braune Punkte und ei-ne braunpurpurne Lippe, welche deut-lich dunkler ist als die von Paph. roh-manii ist. Das Staminodium von Paph. barbatum ist halbmondförmig und im Zentrum deutlich weniger geädert.Paph. tonsum hat deutlich horizontal abstehende Petalen. Die Flecken auf

den Petalen sind deutlich weniger. Das Staminodium ist fast nierenförmig und nicht grün geädert, während das von Paph. rohmanii halbmondförmig und im Zentrum grün netzartig geädert ist.Diese Unterschiede zeigen, dass das Paph. rohmanii tatsächlich eine von Paph. barbatum und Paph. tonsum klar abgrenzbare Art ist. In den kommenden Jahren wird es in-teressant sein, noch mehr über diese neue Art zu erfahren, ihre Variabilität, ihren Standort und die Standortbedin-gungen sowie ihre Stellung innerhalb der Sektion Barbata.

DanksagungWir bedanken uns bei Gus Benk, der uns auf die Entdeckung hinwies und uns die Informationen zu der neuen Art mitteilte, Parry Ow für einige der Bilder und Rohman Ikhwan, dem Be-sitzer der Gärtnerei Rohman Orchids in der Provinz Aceh auf Sumatra, In-donesien, für alle Informationen und Bilder vom Standort.

IntroductionThis year, new Paphiopedilum have been discovered in Indonesia, in-cluding Java, Sumatra and Sulawe-si. In March 2017, we described with N. Bougourd P. agusii, a new species from the center of Java (Cavestro, 2017). Four new species from the prov-ince of Aceh in Sumatra have just been described. One, named P. dodyanum, belongs to the Cochlopetalum sec-tion (Cavestro, 2017). The other three species, P. lunatum, P. bungebelan-gi and P. zulhermanianum Cavestro, are part of the Section Barbata V.A. Albert & Börge Pett. They have been described by Metusala (2017) and Ca-vestro (2017).In this publication we present a new Paphiopedilum named Paphiopedilum rohmanii. Its name refers to the name of the discoverer, Rohman Ikhwan. It also belongs to the Barbata section but according to our information, it originates from the north of Sumatra in the province (Regency) of Aceh Ten-gah. This Paphiopedilum has a white dorsal sepal tinged with light purple and brown-purple veined, petals de-fl exed, green veined and spotted with light brown, a light brown lip veined with brown, a lunate staminode white and green reticulated in the middle. These characteristics are somewhat different from the species of the sec-tion Barbata (Kraenzlin) V.A. Albert & Börge Pett.In Sumatra this section includes P. barbatum (Lindl.) Pfi tzer, P. bulle-nianum (Rchb.f.) Pfi tzer, P. javanicum (Reinw. ex. Lindley) Pfi tzer, P. su-perbiens (Rchb.f.) Stein, P. tonsum (Rchb.f.) Stein and also the recent-ly discovered Paphiopedilum: P. bun-gebelangi Metusala, P. lunatum Me-tusala and P. zulhermanianum Ca-vestro. P. bungebelangi and P. luna-tum grow in the province of Aceh, P.

zulhermanianum is from Western Su-matra. None of these newly described species resembles P. rohmanii. On ex-amining the fl ower, the closest species is P. tonsum. However, there is also a lesser resemblance to P. barbatum.

Paphiopedilum rohmanii Cavestro & O. Gruss sp.nov. resembles Paphiopedilum barbatum (Rchb.f.) Stein but differs in defl exed, twisted at apex, more mottled brown petals, a staminode lunate (not subreniform) and green reticulated in the middle. Etymology: Named after Rohman Ikhwan, owner of Rohman Orchids in Aceh, Sumatra (Indonesia).

DescriptionA terrestrial herb of one or two growths and more. Leaves 4 – 5, nar-rowly oblong to oblong-elliptic, obtuse or tridenticulate at apex, 14 – 21 cm long and 2.5 – 2.8 cm wide, green, green veined and dark green mottled. Infl orescence one fl owered; peduncle 15 – 24 cm long, purple and fi nely pu-bescent; bracts ovate-elliptic, obtuse, 1 – 1.3 cm long, green spotted with pur-ple. Flowers 9 – 11 cm across; dorsal sepal white and purple tinged, white in apical part, brown-purple veined; syn-

sepal white and purple veined; petals white, green tinged in the middle and the upper margin, green to green-pur-ple striated, spotted with light brown; side-lobes of labellum pale rose to light brown, mid-lobe pale brown and brown veined, pale green in apical part; staminode pale green and green reticulated in the middle. Dorsal se-pal broadly ovate, margins undulate and ciliate, 4.5 cm long and 4.5 wide. Synsepal elliptic-ovate, concave, ob-tuse, 3 cm long and 1.6 cm wide. Pet-als more or less defl exed, elliptic-ob-long, obtuse, twisted at apex, ciliate, 5 – 5.5 cm long and 1.7 – 2 cm wide. La-bellum saccate, narrowing towards apex, 4.4 – 4.8 cm long and 2 – 2.5 cm wide; side-lobes incurved. Staminode lunate, 10 mm long and 7 mm wide, 2 apical lateral and short teeth slightly incurved and obtuse. By its fl ower and its defl exed petals this new species apparently resembles P. callosum (Rchb.f.) Stein which is in Cambodia, Thailand and Laos. Among the species of Sumatra P. rohmanii has a resemblance to P. barbatum and P. tonsum. P. barbatum is found on the Malay Peninsula and to the North and the center of Sumatra. These two spe-cies are therefore geographically close to P. rohmanii. However, the fl ower of P. barbatum is very different. P. barba-tum has petals slightly defl exed and not spotted, a brown-purple lip much darker than that of P. rohmanii. The staminode of P. barbatum is lunate and less reticulated in the middle.P. tonsum has slightly drooping petals in horizontal position. The spots on the petals are less numerous. The sta-minode is subreniform and not green reticulated whereas that of P. rohmanii is lunate and green reticulated in the middle. These differences show that P. rohmanii is indeed a distinct species of P. barbatum and P. tonsum.

Bougourd, nous avons décrit P. agu-sii, une nouvelle espèce originaire du centre de Java (Cavestro, 2017). Dans la province d’Aceh à Sumatra, quatre nouvelles espèces viennent d’être dé-crites. L’une, nommée P. dodyanum, appartient à la section Cochlopetalum (Cavestro, 2017). Les trois autres es-pèces, P. lunatum, P. bungebelangi et P. zulhermanianum Cavestro font partie de la section Barbata V.A. Al-bert & Börge Pett. Elles ont été dé-crites par Metusala (2017) et Ca-vestro (2017).Dans cette publication, nous présen-tons un nouveau Paphiopedilum nom-mé Paphiopedilum rohmanii. Il appar-tient aussi à la section Barbata mais selon nos infomations, il est originaire du nord de Sumatra dans la province de Aceh Tengah. Ce Paphiopedilum a un sépale dorsal blanc ombré de pourpre clair et strié de marron-pourpre, des pétales défl échis striés de vert et tachetés de marron clair, un labelle brun clair veiné de brun, un staminode en demi-lune blanc rosé et

réticulé de vert au centre. Ces caracté-ristiques sont différentes des espèces de la section Barbata (Kraenzlin) V.A. Albert & Börge Pett. A Sumatra cette section comprend P. barbatum (Lindl.) Pfi tzer, P. bullenianum (Rchb.f.) Pfi t-zer, P. javanicum (Reinw. ex Lindley) Pfi tzer, P. superbiens (Rchb.f.) Stein, P. tonsum (Rchb.f.) Stein et aussi les nouveaux Paphiopedilum décrits ré-cemment: P. bungebelangi Metusala, P. lunatum Metusala et P. zulhermani-anum Cavestro. P. bungebelangi et P. lunatum sont originaire de la province d’Aceh, P. zulhermanianum de l’ouest de Sumatra. Aucune de ces espèces nouvellement décrites ne ressemble à P. rohmanii. A l’examen de la fl eur, l’espèce la plus proche est P. tonsum. Cependant, on notera aussi une res-semblance moins importante avec P. barbatum.

DiscussionCette nouvelle espèce ressemble en apparence, par sa fl eur et ses pé-tales défl échis, à P. callosum (Rchb.f.) Stein qui se trouve au Cambodge, en Thaïlande et au Laos.

P. bar-batum a des pétales faiblement dé-fl échis, sans aucune tache, un labelle marron-pourpre beaucoup plus foncé que celui de P. rohmanii. Le staminode de P. barbatum est lunate et moins ré-ticulé au centre. P. tonsum a des pétales légèrement re-tombants. Les taches sur les pétales sont moins nombreuses. Le staminode est subréniforme et non réticulé alors que celui de P. rohmanii est lunate et réticulé. Ces différences montrent que P. rohmanii est bien une espèce dis-tincte de P. barbatum et P. tonsum.

Abstract: A new species, Cylindrolo-bus oliviacamposiae Naive, Maban-ta, & Cootes (Orchidaceae) is de-scribed and illustrated from the Phil-ippines. This new species is compa-rable to C. datuguinai but distinct in the shape of the labellum and col-our of the fl oral bracts. Information on the habitat and ecology as well as its relationship to other similar species of the genus are provided. With this discovery, there are now nine species of Cylindrolobus known from the Philippines.

Keywords: Bukidnon, Philippines, CEDAR, Cylindrolobus oliviacampo-siae, Orchidaceae, new species.

IntroductionOne never ceases to be amazed at the continuous parade of previously unde-scribed species being found in north-ern Mindanao, specifi cally in Bukid-non province. Bukidnon, landlocked by mountain ranges and forest re-serves, is a haven for botanists and plant enthusiasts. It harbors a diverse fl ora and fauna amongst its numerous mountains and forest reserves that provide a habitat for wildlife and sup-ports diverse vegetation types which are rich in plant genetic resources, in-cluding orchids (Naive, 2017).During the second author’s expedition to one of the forest reserves of Bukid-non province, he came across an un-known epiphytic orchid species be-longing to the genus Cylindrolobus. He collected it and contacted the fi rst and third author to help him deter-mine its identity. After a careful ex-amination of the morphological char-acters of the species and a search of the relevant literature from the Phil-ippines and neighboring countries, it turned out that the collected speci-men does not match any other known species. We hereby take this opportu-nity to describe this orchid as Cylin-

drolobus oliviacamposiae, a species new to science.The genus Cylindrolobus was original-ly proposed by Dr. Carl Blume as a sec-tion of Eria in 1825. In the year 1981, Friedrich G. Brieger raised the sec-tion to generic level in the German pe-riodical ‚Orchideen‘. The type species for this genus is Cylindrolobus com-pressus (Blume) Brieger. The gener-ic name refers to the shape of the la-bellum (Cootes, 2011). They are char-acterized by their, usually, cylindrical stems, that are leafy on the upper half. The fl owers appear singly, and have a number of colored bracts on the pedi-cel.Members of the genus Cylindrolobus are represented by approximately 35 species which are distributed in India, Sri Lanka, Thailand, Peninsular Malay-sia, Philippines, throughout Indone-sia and Borneo. The Philippines has at least nine species, all of which appear to be endemic (Naive et al., 2016).

Taxonomic Treatment

Cylindrolobus oliviacamposiae Na-ive, Mabanta et Cootes sp.nov.

Type: Philippines, Northern Mind-anao, Bukidnon, Impasug-on, Im-palutao, Center for Ecological De-velopment and Recreation (CEDAR), epiphytic in deeply shaded loca-tion, elevation 780 m, coordinates 8°14’54” N by 125°02’09” E, 24 March 2017, M.A. Naive 018/2017 (Holotype: cmUH00010874).

Diagnosis: Cylindrolobus oliviacam-posiae Naive, Mabanta, & Cootes is most similar to Cylindrolobus da-tuguinai Naive, M.D. De Leon & Bue-navista. However, it can be recog-nized by having a marked difference in the number of fl owers (1 vs. 2 to 4), color of the fl oral bracts (maroon vs. pale yellow) and ovary with pedicel (maroon vs. purple). It also differs in

Dorsal sepal narrowly ovate to oblong, with up to 7 veins, concave, entire, 1.2 to 1.4 cm long by 0.5 to 0.6 cm wide, apex slightly cucullate. Petals linear to nar-rowly lanceolate, slightly falcate, with up to 3 veins, 1 to 1.2 cm long by 0.20 to 0.25 cm wide. Lateral sepals broadly triangular, falcate, with up to 6 veins, margin entire and slightly involute, 1 to 1.2 cm long by 7.5 to 8 cm wide, apex cucullate. Labellum trilobed, 0.8 to 1.0 cm long; side lobes narrow-ly triangular, erect, pointing forward, slightly falcate, margins ciliate, en-closing the column; mid-lobe ovate, villose, with one longitudinal, villose ridge, margins ciliate, apex acute, 0.5 to 0.6 cm long by 0.3 to 0.3.5 cm wide, recurved.

Distribution: Cylindrolobus oliviacam-posiae is a local endemic species, on-ly known from the type locality in the Center for Ecological Development and

Recreation (CEDAR), Barangay Impal-utao, Impasug-ong, Bukidnon, North-ern Mindanao, Philippines.

Ecology: Cylindrolobus oliviacamposi-ae is an epiphytic herb, found growing from a fallen tree in secondary forest, with deeply shaded localities at eleva-tion 700 to 800 meters above sea level.

Etymology: Named after the second author’s cousin Mrs. Olivia Mabanta Campos, who has helped and inspired the former in making Bukidnon a sec-ond home while pursuing a career in pineapple farming.

Phenology: August to October.

Conservation status: EN B2ab(iii). A small population was seen at the type

locality, which is being developed as a tourist attraction. The advent of peo-ple will cause destruction of this spe-cies.

Notes: Cylindrolobus oliviacamposi-ae Naive, Mabanta & Cootes is most similar to Cylindrolobus datuguinai Naive, M.D. De Leon & Buenavista. However, it can be recognized by hav-ing a marked difference in the number of fl owers (1 vs. 2 to 4), color of the fl o-ral bracts (maroon vs. pale yellow) and ovary with pedicel (maroon vs. pur-ple). It also differs in the shape of the labellum, a much ciliate margin of the midlobe and in the shape of the side lobes.

Also, the vegetative morphology of the said two closely similar species could tell that the species are different. Cy-lindrolobus oliviacamposiae has short-er stem unlike C. datuguinai which have a much longer stem. Leaves of C. oliviacamposiae are papery whereas C. datuguinai are leathery.

As the new species is currently known only from a single collection, and the orchid fl ora of CEDAR, Bukidnon is generally poorly known, an assess-ment of its conservation status can obviously not be made. The new spe-cies was only seen in this one locality where it was not abundant.
