Heterotypic Synonyms:

Satyrium fallax Schltr., Bot. Jahrb. Syst. 53: 532 (1915).
Description:
A terrestrial herb 2-9 dm. high, glabrous except for the roots; tubers ellipsoid to cylindrical, 1.5-2.5 cm. long, 5-18 mm. in diameter, ± tomentose; roots slender, flexuous, pubescent. Stem erect, slender to stout, with 1-3 leaves in the lower part and several sheaths. Leaves altogether 4-8, the lowest 1 or 2 sheath-like, obtuse, the middle 1-3 spreading, close together, broadly elliptical to lanceolate, acute, up to 4-24 cm. long and 2-9 cm. broad, the upper ones adpressed, lanceolate, acute, much smaller, the largest 3-11 cm. long, l-2(-3) cm. broad. Inflorescence cylindrical, 3-37 cm. long, 1.5-2.5 cm. in diameter, rather densely to rather loosely 6- to many-flowered; bracts soon reflexed, lanceolate, acute, 1-2.5 cm. long. Flowers curved outwards, sessile, green or yellowish-green, rarely whitish or pinkish; ovary 6-8 mm. long. Sepals and petals decurved, united to one another and to the lip in their basal half or third; intermediate sepal oblanceolate-oblong, rounded, 4.5-6 mm. long, scarcely I mm. broad; laterals obliquely curved elliptical-oblong, a little longer but nearly twice as broad. Petals as intermediate sepal but shorter and narrower. Lip fleshy, ellipsoid, hooded, the apex very shortly reflexed, 5-6.5 mm. long; spurs slender, parallel to ovary, (8-)10-17(-22) mm. long. Column curved, 4-4.5 mm. high; stigma erect, transversely elliptical, 1.5-2 mm. high, 2-3 mm. broad, rostellum 3-lobed, the side lobes shortly triangular, the middle lobe much longer, broadly shovel-shaped from a narrow base.
Habitat:
Montane grasslands, often among rocks, rarely in damp places. Alt. 1350-3000 m.
Phenology:
Flowering in October-March.
Notes:
It is allied to Satyrium crassicaule Rendle. In Satyrium chlorocorys, however, the tubers are ellipsoid to cylindrical, the inflorescence is lax, flowers are yellowish green to olive maroon, and the column is strongly curved at the base. In Satyrium crassicaule there are no tubers, the inflorescence is very dense, flowers are pink, mauve or white, and the column is slightly curved at the base.
Cultivation:
As given for the genus.
Distribution:
Uganda, Tanzania, Angola, Zambia, Malawi, Zimbabwe, Mozambique.
