Afr. p. 20, t. 10, fig. 1. 
A native of Cape Colony. 
Main stem barrel-shaped, three inches high and nearly as 
thick, firm in texture, gray in the lower part, green and papillose 
upwards, the centre of the flat top occupied by conical papille, 
the circumference producing numerous cylindrical spreading 
curving branches one inch to three inches in length and about 
half an inch in thickness. Papille projecting about a: line, 
rounded above, rhomboidly decurrent downwards, bright green, 
quite glabrous and without spines. Leaves produced from the 
upper papillz and soon deciduous, linear-lanceolate, fleshy, glau- 
cous, a line and a half to two lines long. Flowers sparingly pro- 
duced, solitary, on fleshy pedicels an eighth of an inch long. 
Involucre campanulate, an eighth of an inch broad, with a few 
small broad ovate membranous bracts, the glands bright yellow, 
entire, round, spreading, concave, the scales of the throat round, 
ciliated. Male flowers ten to twelve in an involucre. Styles 
connate throughout. Capsules hispid. 
This is a plant, figured by Burmann, of which nothing has 
been heard for the last century, but which Mr. Cooper has now 
fortunately rediscovered. In general habit it agrees with EH. 
Caput-meduse, from which the entire glands of the involucre 
distinguish it at a glance.
