DECaBELONE Barklyi, Dyer, MSS. 
Under Tab. 6115 it was mentioned that the Royal Gar- 
dens, Kew, possessed specimens both living and in spirit, as 
well as drawings and analyses, from H. E. Sir Henry Barkly, 
Dr. Shaw, and Mrs. Barber, of a second species of Decabelone 
from Little Namaqualand. As was stated there it is closely 
allied to D. elegans, the flowers being extremely similar, but 
the branches have nearly twice the number of angles; and 
the two lateral sete of the spines are more slender and de- 
flexed instead of erect. 
The first discovery of this interesting plant is due to H. E. 
Sir H. Barkly, who sent a sketch of the plant in J anuary, 1874, 
having found it three years previously growing in the Karoo, 
near the Orange River. Shortly after Dr. Shaw, who, as well 
as M‘Lea, had found it in the same locality, sent to Kew 
Specimens in spirit, and a careful analysis. Not having seen 
the description of Decabelone, Dr. Shaw rightly recognised 
the generic distinctness of the plant from other Stapeliew, and 
proposed that it should constitute a new genus, to be named 
in honour of the Governor of the Cape. I have endeavoured, 
as far as the specific name will allow, to give effect to Dr. 
Shaw’s wishes. : 
The present plate is partly founded upon a fine drawing 
for which Kew is indebted to Mrs. Barber, partly upon speci-
