in a note appended to the description of the genus, it 
says, ‘‘ Certainly closely allied to Disa although the stigma 
is hardly pulvinate.”’ 
The genus was named at Dr. Harvey’s suggestion, after 
the Rev. J. Brownlee, a missionary stationed in King 
William’s Town, Caffraria, and an observing naturalist, 
who discovered this and another species (B. parviflora, 
Harv.) in sheltered spots amongst trees near the above 
station. A third D. recurvata, Sond. (in Linnea, vol. xix. 
p. 106), also from Caffraria, has been added to the genus. 
D. cerulea has since been found in many other localities 
in 8.E. Africa, from Natal, alt. 3-4000 ft., to Grahamstown, 
and also in Madagascar.—J. D. H.
