XIV. HESPERANTHA, Ker. 
Perianth rotate, with acylindrical tube and six subequal, oblong, 
spreading segments. Stamens inserted at the throat of the perianth- 
tube, divaricating ; filaments short, free ; anthers lanceolate. Ovary 
3-celled ; ovules crowded in the cells; style as long as the perianth 
tube, with three long, subulate, falcate, entire branches. Capsule 
small, turbinate, membranous, loculicidally 3-valved. Seeds small, 
globose, or angled by pressure. 
Rootstock a small tunicated corm, flat at the base; leaves few, narrow, 
distichous; flowers small, arranged in lax spikes; spathe-valves herbaceous 
in texture,’ lanceolate, usually about as long as the perianth-tube, Only 
— from Geissorhiza by its longer style-branches and longer green spathe- 
valves, 
Distris. Besides the Cape species there is one in Abyssinia and one in the 
Cameroon Mountains,
