This species is still somewhat problematic, being known only from 
the type material with which to date it has been impossible to iden- 
tify precisely any of the modern collections. The species is clearly 
very close in habit, inflorescence, leaf-texture and leaf-venation to 
the variable E. exserto-venosum Klatt, but the leaves are more obovate 
or oblanceolate than in any as yet described variety of the latter 
- Moreover, the leaves are rather conspicuously and bluntly 
Cuspidate at the tip. Finally Kunth, |. ¢., in describing the species 
States that the heads are about 12-flowered, that is to say have half 
again to twice as many florets as are found in E. exserto-venosum Klatt. 
Material approximating E. fastigiatum has been collected in Colom- 
bia See Robinson, |. c.) but its identity must be subject to doubt 
until the type can be re-examined.
