Different specimens of this plant vary much in appearance, as the stems which 
sprivg up after the annual fires are shorter, stouter and less leafy than the earlier and 
more normal leafy growth. Pax describes the involucres of E. trichadenia as pilose,. 
but the pubescence on the type specimen consists of minute spreading hairs, scarcely 
visible to the naked eye. It varies considerably in different specimens, even 10 the 
same gathering, and usually the involucres are glabrous.
