RAPHIOffAGMB UTILIS. (Asolepiadeae. ) 25547. Bulbs of Eoanda 
rubber from Oehileso, Africa. Presented by Mr. T. W. 
Woodside, Benguella, Angola. "A rubber producing member 
of the milkweed family recently described as a new species. 
The plant may be described as a perennial herb or very low 
shrub. There is a large, fleshy, flattened, turnip-shaped 
perennial root said to attain a diameter of 5 to 6 inches, 
tho the present supply does not contain roots larger than 
4 inches. The other parts of the plant are annual except 
for a short stem or crown which produces a succession of 
short branches but apparently only one at a time. The' 
structure and habits of growth indicate that the plant be- 
haves in nature as an extreme desert type able to survive 
with very little water and requiring several years to 
reach maturity. It is necessary to ascertain whether the 
plant can be grown in the U.S. either from seeds or from 
cuttings." (O.P. Cook.) For propagation; plants available 
later.
