German East Africa with fewer, smaller and more elliptic leaves than in 
-has been distinguished under the names of Z. shirensis, E. trachyoupes pe 
carpa,and E. multiradiata. This form appears to me always to consist 0 eyo 
growths after the annual burnings of the savannahs, in some cases the rae? y 
even bear branches on which the leaves are lanceolate and more numerous, e 
as in the type, whilst other specimens from Nyasaland are quite the s 
Abyssinian plant, and structurally all are identical. Other species vary 1
