 fibrillose, dark glossy-brown ; fr. dimorphous, the barren one sessile, 6-9 in. 1., 

 3-4 in. br., cut down |-| way down to the rachis into blunt lobes, the fertile 

 one 2-4 ft. 1., 12-18 in. br., long-stalked, pinnate ; pinnae 1 in. or more apart, 

 narrowed or stalked at the base, 6-12 in. 1., - in. br., the point acuminate, the 

 edge more or less deeply inciso-crenate ; texture subcoriaceous ; rachis and both 

 sides naked ; main veins not distinct to the edge ; areolce copious, free veinlets 

 few ; sori immersed in a single row halfway between the edge and midrib. P.

 full-brown ; st. 6-12 in. 1., firm, erect, glossy ; fr. 6-18 in. 1., 8-12 in. br., with a

 slightly adnate at the base, those of the barren fr. the broadest ; texture sub-

 hidden ; sori in a single row midway between the edge and midrib. Hk. Sp. 5. 

 p. 89. Pleuridium, J. Smith. P. crenulatum, Mett. 



Hab. Malaccas and Philippines. P. angustatum, Blume (P. Lindleyanum, Wall.), and 

 P. palmatum, Blume, appear to be varieties of one species, but the latter has only a very 

 few pinnae, which do not reach down to the rachis.
