Native of Mexico, the West Indies and Tropical America, 
now widely distributed in the Transvaal Province and rapidly 
spreading along roads and railways to Rhodesia and the 
Katanga Plateau. 
It keeps fairly green late in the winter, and is closely eaten 
by stock in late autumn and early spring. Either green or dry, 
it is a favourite with horses, mules and donkeys, but the yield 
of pasturage is low and it is somewhat inaccessible, owing to 
the decumbent habit of the plant. 
It differs from G. globosa, Linn.—with which it has been 
confused—in habit and the much smaller, less globose heads which 
elongate during flowering, and by its usually white bracts. The 
true G', globosa, Linn., with larger, more globose heads and tawny 
bracts, has been found in Natal and tropical Africa, but does 
not appear to occur in the Transvaal, the specimens so named

rh uin’s figure is not quite characteristic of our plant, 
which, ee agrees exactly with tropical American material 
so named in the Kew collections, and I have no doubt that they 
are conspecific,
