Sourn Arrica: without locality, cultivated specimens in Herb. Haworth! and 
Herb. Kew! 
Described from living plants. According to Haworth this species was introduced 
into cultivation before 1800 and may still exist in English gardens, but I have not 
seen it during the past ten years. _ It differs from all other species I have seen by 
the broad and short tubercles on the stems being more closely placed and more 
abruptly apiculate. Its flowers closely resemble the minutely ciliated forms of 
D., hirtella, Sweet, but are much smaller.

pentagonal, with its sides sloping underneath it (not vertical), and 
the rim rising considerably above the margin of the outer corona so 
as to form a sort of basin containing the corona, minutely puberulous, 
whitish, very distinctly spotted all over with purple-brown ; outer
