The area in which the remaining Schefflera procumbens occurs is under the protection of the Nature Protection Trust of Seychelles. Cultivation of this plant, which would act as a safeguard against this species extinction, has been attempted, but unfortunately failed (1).

Schefflera procumbens is a species of plant in the Araliaceae family. It is endemic to Seychelles, now confined to six small areas on Silhouette Island at altitudes between 400 and 700 meters, having become extinct on Mahé.
Schefflera procumbens is a climbing epiphyte, with gray bark, palmate leaves on petioles up to 20 cm in length, and cream-colored, globular fruits in clusters.

Schefflera procumbens is an epiphyte (2): a plant that uses another plant, typically a tree, for its physical support but does not draw nourishment from it (6). It grows up to the uppermost parts of the forest, known as the canopy, where it flowers and fruits (2).

Found entwined with trees in forests, which it uses for support, Schefflera procumbens is a rare epiphyte with grey bark. Each leaf is composed of 10 leathery leaflets, each up to 15 centimetres long, radiating from a central stem measuring 20 centimetres long (2) (3). The fleshy, greenish flowers of Schefflera procumbens are borne in tight clusters on spikes and measure just half a centimetre wide (3), while the round, cream-coloured, fleshy fruits may be up to eight millimetres across (2).

Schefflera /ˈʃɛflərə/[1] is a genus of flowering plants in the family Araliaceae. The plants are trees, shrubs or lianas, growing 1–30 metres (3 ft 3 in–98 ft 5 in) tall, with woody stems and palmately compound leaves. The circumscription of the genus has varied greatly. Phylogenetic studies have shown that the widely used broad circumscription as a pantropical genus of over 700 species is polyphyletic, but it remains to be seen how this will affect the classification of the genus.[2][3]
Several species are grown in pots as houseplants, most commonly Schefflera actinophylla (Umbrella Tree) and Schefflera arboricola (Dwarf Umbrella Tree). Numerous cultivars have been selected for various characters, most popularly for variegated or purple foliage. Schefflera species are used as food plants by the larvae of some Lepidopteran species including Batrachedra arenosella (recorded on S. stellata). Schefflera arboricola and Schefflera actinophylla can be used to attract birds.[4]
The genus is named in honor of Johann Peter Ernst von Scheffler (born in 1739), physician and botanist of Gdańsk, and later of Warsaw, who contributed plants to Gottfried Reyger for Reygers book, 'Tentamen Florae Gedanensis'.[5][6][7]

This species is endemic to the Seychelles. It is only known from three sites on Silhouette (Friedmann 1994, J. Gerlach pers. comm. 2006). The entire area of Silhouette is 20 km² (National Statistics Bureau 2005). The EOO and AOO are estimated to be less than 20 km² and 10 km² respectively. In 1901, the species was collected on Mahé by Thomasset (Summerhayes 1931), but it has not been recorded on Mahé since that collection.
