Scientific Name:Duidaea

Has developed three distinct species, and is perhaps closest to Gongylolepis in general character. Its leaves are 1-nerved and linear, flowers have a simplified or "advanced" vascularization; and the pollen shows a prominent departure in form and ornamentation.

The two genera, Neblinaea and Achnopogon are monotypic, and each is geographically restricted to a single sedimentary massif. Both have compound, laterally disposed inflorescences and small heads with five or fewer flowers, the corollas of simple vasculature. Beyond these common features they differ greatly.
