Dyschoriste consists of about sixty species, twenty-two 
of which are found in Tropical Africa, while a few occur 
in South Africa, Madagascar and India, and the remainder 
in America, from Texas to Peru. Most are small shrubs 
of scrubby habit, and but few have found their way 
into cultivation. Some have been cultivated under Calo- 
phanes, a name published by D. Don in Sweet’s ‘ British 
Flower Garden,” ser. 2, tab. 181 (1833), which must be 
superseded by Dyschoriste, Nees, published in the pre- 
ceding year, ‘ 
Dyschoriste is allied to the well-known genus Tiuellia, 
from which it differs in having only two ovules in each 
cell, while the latter has three or more. os 
D. Hildebrandtii was discovered by Hildebrandt at 
Kitui, in British East Africa, and it was afterwards 
collected in Usambara by Holst. The plant here figured 
flowered in the Water Lily House at Kew in October, 1903, 
and it was still in full bloom in June of the present year.
