A Guide to Medicinal Plants in North Africa 31 Morphological description A small annual plant, 10-12 cm. high, glabrous with erect, finely striated stems. The leaves are finely dissected and slightly fleshy. The flowers are grouped in umbels of 2 to 4 branches. The flowers are small, with 5 free petals. The fruit is a diachene, 6-10 mm. long, and is covered with dense silky white hairs. The plant has a strong smell of anise. It usually flowers in early spring (February to April). Geographical distribution Local: Common in the Algerian Sahara. Regional: North Africa. Global: Commonly distributed throughout the Sahara, where it is considered endemic. Its presence is also mentioned for the Canary Islands. Ecology It is an annual that grows in wadis, on sandy-grav- elly soils in arid conditions where the annual rainfall does not exceed 100 mm. Status According to the IUCN criteria this endemic species falls into the "EN" category. The threat to this little annual from human collec- tion is mainly felt around settlements. In the wild, the best means of conservation is the remoteness of the sites, or a seed bank that contains the plant during drought. The best way to conserve this annual is to collect the seeds and sow them in nurseries. So far there is no data on its propagation and conservation. Part used The leaves and seeds. The fruits are collected by the nomads for their own use, usually in spring when the fruits are ripe.
