Easy as it is to distinguish the' extremes of the forms combined here, 
and to find diagnostic characters which look valid when onlv the extremes 
are considered, the differences are found inconstant and the gaps are 
bridged over with the accumulation of many specimens. In our herbaria 
this accumulation has reached the point where I can no longer see a good 
specific distinction between any one of them and some other. In 
place of the hitherto recognized species, we will better recognize 3 or 4 
inconstant varieties. 
a. Var. euirregularis. 
, Frond simply pinnate: sori small and \ery numerous, sometimes much 
more so even than Presl figured, and irregularly scattered. Presl, surely 
in error, credits the type to "Mexico.

Simply pinnate fronds with the sori more like those of the next variety 
are: Foxworthy B. S. 1962, Pampanga; Topping 424, Elmer 6684, Mt. 
:Mariveles; Copeland s. n. Mt. Maquiling. Elmer 6230, is simple, but
