PTERIS (Lrrosrocuta) parmara, Willd. 
Palmated Pteris. 
Preris (Litobrochia) palmata; caudex ascending; stipites tufted, ebony-black, 
setoso-squamose below ; fronds very polymorphous, cordate ; young and ste- 
rile ones obtusely three- to five-lobed ; fertile ones thick and fleshy when re- 
cent, coriaceous when dry, often gemmiparous at the base beneath, palmately 
three- to five-lobed; lobes variously and deeply divided or pinnatifid, frequently 
so as to leave a broad disk to the frond; the segments more or less acumi- 
nated and more or less broad, lowest pair of primary lobes generally with 
long segments near the base, pointing downwards, sometimes again pinna- 
tifid; sinuses rounded; costa and costules ebeneous at the back of the 
frond; sori continuous, narrow ; veins anastomosing, sunk in the substance 
of the frond and very obscure.

Opinions are divided as to the propriety of keeping the Pteris 
palmata of Willdenow distinct from the Linnean P. pedata, and
