Haz. Ascension Island. 
Tufts brownish-black, loose. Stems scarcely 2 inches 
high, pinnate with alternate branches, smooth or destitute 
ofscales. Leaves loosely imbricated, the upper and more 
convex lobe broadly ovate, with a more remarkable linear 
spur or appendage at the base than that of the lower lobe. 
Stipules oblong, with rather an obtuse sinus, furnished with

other. From Jung. diclados, Weber, this species may be 
known by its smaller size, less imbricated leaves, by their 
obtuse segments and above all by the stems being destitute 
of scales,
