AFRICAN

ORCHIDS

Solenangis clavata (Rolfe) Schltr., Beih. Bot. Centralbl. 36(2): 134 (1918).
Homotypic Synonyms:
Angraecum clavatum Rolfe in D.Oliver & auct. suc. (eds.), Fl. Trop. Afr. 7: 145 (1897).
Heterotypic Synonyms:
Saccolabium oeonioides Kraenzl., Bull. Soc. Roy. Bot. Belgique, Compt.-Rend. 38: 62 (1899).
Description:
Stems elongated, sometimes branched, to 50 cm long or more; roots numerous, long, branching, 1-2 mm in diameter. Leaves numerous, distichous, 2-4 x 1-2 cm, elliptic, unequally and obtusely bilobed at the apex. Inflorescences arising along the stem opposite the leaves, 6- to 10-flowered. Pedicel and ovary 6-8 mm long; bracts l mm long. Flowers greenish-white. Sepals and petals 3-4 x 1.5-2 mm, elliptic, rounded. Lip rather obscurely trilobed, barely 1 mm long, grading into a wide-mouthed spur 10-13 mm long, becoming narrow, then swollen at the apex. Capsule ellipsoidal, 20 x 6 mm.
Habitat:
Epiphytic, lithophytic, or terrestrial in forest and marshy areas, 1300-2000 m.
Cultivation:
Scandent plants like this usually seem better mounted, but high humidity seems so essential to this species that I find it grows better in a pot. Possibly as the plants grow larger, they would benefit from having a slab of bark or even a moss pole at the back of the pot for them to root into. Intermediate to warm temperatures and fairly heavy shade are best.
Distribution:
Cameroon, Congo, Ghana, Ivory Coast, Liberia, Nigeria, Rwanda, Sao Tome, Zaire.

Habitat:
Epiphytic on twigs and small branches in montane forest, usually sunk in moss and lichen, 1800-2250 m.
Cultivation:
This little species grows surprisingly well, either mounted or in a pot, in shaded, humid conditions at intermediate temperatures.
Distribution:
Guinea Bissau, Kenya, Malawi, Tanzania, Zimbabwe.
