A rather interesting little plant, forming in some respects a link between 
the Sections Semilimbidium and Heterocaulon. It is especially noteworthy 
for the inequality of the leaves, which gradually increase in size upwards, 
becoming at the same time narrower and more acute, giving a somewhat 
fan-shaped outline to the frond. Тһе widely-spreading, scarcely conduplicate 
vaginant laminæ of the upper leaves and the variable border (which on the 
vaginant lamina is occasionally intramarginal) are other characters. 
lt is perhaps most nearly allied to F. vittatus, Wils., but the areolation in 
that is short to base, the border is quite different (usually intramarginal on 
the vaginant lamina), the upper cells much more obscure, and the nerve and 
border much more pellucid. F. brevifolius, Hook. Ё. & Wils., has not the 
peculiar foliation of our plant. F. semilimbatus, Hampe & C. Muell., has the 
leaves subequal, and all the leaves acute and narrower, and а subexcurrent 
nerve. F. ramiger, C. Muell. & Beckett, is also near it, but has fewer leaves, 
with the superior lamina of the upper pair forming a peculiar, narrowly 
ligulate point. 
The vaginant lamina in the lower leaves of our plant frequently occupies 
the greater part of the leaf, and is often rather amplexicaul than vaginant, 
but the apex has not the peculiar form characteristic of the best marked 
species of the Section Heterocaulon.
