Philippine Diversity of the

Family LamiaceaeThe Mint Family

OverviewOverview of the Taxa

Lamiaceae, also called Labiatae, is the mint

family of flowering plants.

The enlarged Lamiaceae family contains

about 239 genera and 6,900 to 7,200 species,

the largest family of the order Lamiales.

The family was established by De Jussieu in

1789 as the order Labiatae. The name

Labiatae alludes to the flowers typically

having petals fused into an upper and lower

lip, the flower thus having an open mouth!

Although Labiatae is an acceptable, alternate

name, botanists more often use Lamiaceae

after the genus Lamium.

The majority of the Family Lamiaceae are

annual or perennial herbs. The plants are

frequently aromatic in all parts and contain

volatile oils. The family includes many widely

used culinary herbs, such as basil, mint,

rosemary, sage, savory, marjoram, oregano,

thyme, lavender, and perilla. Some are

shrubs, trees, such as teak, or rarely, vines.

Morphology and AnatomyInternal and External Features of the Taxa

Members of the family Lamiaceae are mostly annual or perennial herbs or shrubs with opposite leaves, when crushed the foliage usually emitting various, mostly pleasant odors.

The stems are usually square, especially when young, erect or procumbent (lying on the ground).

Life cycles of the herbaceous members may be annular or perennial.

Stem of a member of

Lamiaceae

The leaves are opposite or whorled,

decussate and gland-dotted.

The leaves are often strongly aromatic due to

ethereal oils located in the glandular hairs.

The leaf blades are simple, rarely pinnately

lobed (Teucrium) or digitately compound

(Cedronella, Vitex), with entire or toothed

margins.

Flowers usually abundant and quite attractive,

with the sepals and corollas variously united.

Arranged in compact axillary cymes

(verticillasters) or are sometimes single in the

axils of the leaves. Sometimes the

inflorescences are congested as in

Pycnostachys.

Usually zygomorphic, rarely actinomorphic.

Calyx 2-lipped or not and are usually

persistent with 5 teeth or lobes.

Corollas strongly 2-lipped (labiate, hence the

family name), rarely 1-lipped.

Stamens 2 or4(didynamous), epipetalous

Ovaries superior, deeply 4-lobed, rarely not,

with the style mostly arising from the middle of

the 4 lobes.

Fruit comprised of 4 nutlets, although some of

these are not maturing, each containing a

single seed. It may also be a drupe with 1-4

pyrenes, subtended by or enclosed within a

persistent calyx.

The outer surface of the nutlets may be

smooth or rugose (wrinkled). Occasionally the

nutlets are winged (Tinnea).

The family is divided into several subfamilies and tribes of which subfamily Nepetoideae has the most genera.

The largest genera are Salvia (900), Scutellaria (360), Stachys (300), Plectranthus (300), Hyptis (280), Teucrium(250), Vitex, (250) Thymus (220), and Nepeta (200).

The Lamiaceae is closely related to the family Verbenaceae. Several recent, phylogenetic studies have shown that some genera classified in Verbenaceaebelong, however, in Lamiaceae, for example, Vitex and Clerodendrum.

Salvia is the largest

genus of the family,

representing ± 1,000

species, differing

remarkably in their

morphology.

DiversityWorld and Philippine Diversity

of the Taxa

Distribution

The family has a cosmopolitan

distribution.The main centre of diversity is the

Mediterranean region to central Asia.

Members are found in tropical and temperate

regions.

About 60 genera with ± 980 species occur in

the Sub-Saharan African region (Klopper et

al. 2006). In South Africa, there are ± 255

species in 35 genera. The species occur

predominantly in the summer rainfall areas,

but are also found in the winter rainfall areas.

The habitats vary to a great extent. The

species inhabit not only dry, often rocky,

woodland or grassland, but also occur along

forest margins and in fynbos.

Pogostemon cablin P. cablin syn. P. patchouli

Native to Malaysia and the Philippines, Patchouli

is now cultivated in tropical and sub-tropical

regions around the world.

Patchouli has been used extensively in Asian

medicine, apperaring in the Chinese, Indian and

Arabic traditions.

The oil is widely employed as a fragrance and, in

India, as an insect repellent. Patchouli is used in

herbal medicine in Asia as an aphrodisiac,

antidepressant and antiseptic.

It is also employed for headaches and fever.

Patchouli essential oil is used in aromatherapy

to treat skin complaints. It is thought to have a

regenerative effect on skin tone and to help clear

conditions such as eczema and acne. The oil

may also be used for varicose veins and

hemorrhoids.

Pogostemon philippinensis Native to the Philippines

Found in dipterocarp forests.

Plectranthus merrilli Native to the Philippines

Found in mossy forests
