Scientific Name:Achnopogon

A suffrutescent shrub with a short thick primary axis bearing short-shoots terminated by dense rosettes of leaves, and provided with one or several virgate branches. Its phyllaries are strongly bearded, corollas puberulent, and anthers simply caudate but not sagittate, a feature peculiar to this among all the Guayana genera.

Monotypic Glossarion presents a particular problem, seeming to bridge or transcent the limits of the subtribes Gochnatinae and Mutisinae. In facies the shrub recalls the stenopadoid assemblage. The ligulate corolla has five equal lobes; hence, if reconstructed as a wholly gamopetalous corolla, it would certainly be actinomorphic and not bilabiate. Styles are smooth as in members of the Mutisinae, and the leaf base is half-clasping as in Gongylolepis.
