Pteris quadriaurita Retz. 
In forests at 250 m. alt. (No. 595!!), a very ample form, /'. nemoratis Willd., 
I believe, cnjumon in this part of the Worhl. A similar form from a deep ravine 
at 700 m. alt. (No. 5957). 
Pteris sp. near I*, quadriaurita lletz., var. setigera. 
On cliffs in forests at GOO m. alt. (No. 5958). 
In the usually accepted sense, using P. quadiiaiirita as a catch-all, it will 
include this plant, which is distinguishable from other forms by its caudate 
pinnie, narrow segments, basal basiscopic pinnules of several pinna- usually 
enlarged, prominent veinlets and chaffy stipes.
