The singular plant here figured was published upwards 
of a century ago by Linnzeus from specimens (or more 
probably a description) communicated by Thunberg from 
the Cape of Good Hope, and a very fair figure of it was 
published by Francis Masson in 1796, in his “ Stapeliz 
Nove.” Nothing further was known of it till 1882, when 
living specimens were received at the Royal Gardens from the 
Capetown Botanical Gardens, which flowered in 1883, and 
from which the present drawing was made. Previous to 
this, however, living specimens of another species of the 
genus were sent to Kew by Sir Henry Barkly, when 
Governor of the Colony, upon which Mr. N. E. Brown, in 
1880, founded the genus Trichocaulon, to which also he 
referred the Stapelia pilifera of Linnzus. 
The genus Trichocaulon is placed by Mr. Brown next to 
Hoodia (see Tabs. 6228 and 6348), of which it has the 
habit, but differs in the small five-lobed corolla, and deeply 
bilobed processes of the outer corona, which are horizontal 
and subfalcate, Both species are natives of the Karroo
