Original description: Cookson and Eisenack, 1958, p. 41: Broomea ramosa
Body elongate-oval with straight to convex sides narrowing slightly towards the antapical horn, broader basally at the place of origin of the antapical horns and divided into two unequal regions - a longer apical region and a shorter andapical region - by a shallow "girdle" indicated on the surface by two rather faint parallel straight lines; a somewhat hoof-shaped pylome is developed in the apical region of the same surface. The apical horn tapers gradually to a short, straight solid terminal point; the two antapical horns which are of unequal size become more or less completely divided longitudinally into a varying number of somewhat ragged, pointed filaments. The membrane is granular, more coarsely so in the antapical region.

Dimensions:
Holotype - 214 x 38 µm; apical horn c. 76 µm, larger antapical horn c. 38 µm. Range - 176-218 µm x 24-38 µm overall; apical horn 76-90 µm.
