The subject of our plate appears to be a somewhat 
polymorphic species which is rather widely spread in 
Tropical Africa from British East Africa to the Zambesi. 
The genus Erlangea, to which Mr. Moore has referred it, 
differs from the genus Vernonia only in respect of its 
reduced achenes, and in having the pappus reduced to a few 
short, very caducous hairs. Till a few years ago it was 
deemed a monotypic group; now it is believed to consist of 
at least thirty-two species, several of which, however, had 
formerly been included in Vernonia. With the exception of a 
single species from New Guinea which has been referred to 
this genus all the Erlangeas are African. The nearest 
ally of EH. tomentosa is EL. fusca, S. Moore, from which, as 
Mr. Hutchinson points out, it is readily distinguished by 
the bright green leaves and the scariously edged involucral 
bracts. :
