Caudex long, slender, t\yisled, naked ; stipe 6 inches long in 

 the sterile, nearly twice as long in the fertile fronds, glabrous j bar- 

 ren frond ovate, 4-6 inches long, 3-4 in. broad, pinnate ; pinnae 

 7—9, lateral nearly sessile, terminal stalked, form linear-lanceolate, 

 2-3 inches long, ^-| in, broad, acute, finely serrate, obtuse or 

 rounded at the base ; texture coriaceous ; nerves forming a 

 series of arches close to the midrib, thus forming on each side 

 a row of long narrow areolae parallel to the 'midrib; beyond 

 this, nerves are free and simple or forking ; surface naked, except 

 that the midribs and nerves are a little chaffy below ; texture 

 subcoriaceous ; fertile pinnse 7-9, narrowly linear, 1^-2 inches long 

 ratber distant; indusium narrow, marginal. 



Growing among the leaves of a Pandanns, Mount Mahayhay> 



Luzon. 



The venation of this plant is peculiar in the genus, as there is 

 no other species known in which the veins always unite to form 

 areolae. Were it not for the indusium, which is readily overlooked, 

 except in young plants, the specimens would be placed in the 

 genus Acrostichum, group SfenochlcBna, The species could fairly 

 form by itself a subgenus of Lomaria^ characterized by its pecu- 

 liar venation.
