erect stout woody scaly at the summit rooting below, stipites 

 and rachis compressed deciduously scaly below, fronds 1-1 4 

 foot long coriaceous (brownish-green when dry) oblong pin- 

 nate, pinnae remote 5, 16 or 17 erecto-patent inequilaterally 

 and subfalcately ovato-lanceolate long acuminate entire or 

 sinuato-subangulate subauriculate unequally cuneate at the 

 base and gradually attenuated into the petiole scarcely cos- 

 tate, terminal one subrhomboid unequally 3-lobed, veins sub- 

 flabellate diverging from an indistinct costa dichotomous free 

 below anastomosing towards the margin into very elongated 

 subhexagonal areoles, terminal veinlets free or rarely com- 

 bined in arches at the margin, sori linear elongated but 

 varying much in length originating at the centre but never 

 extending to the margin, involucres narrow. — IVall. Cat. n.

 — Our lamented friend Wallich seems to have given more than one name to his 

 specimen of this fine and very distinct species — distinct especially if the venation 

 be considered, for some specimens of Aspl. yiiacrophyllum hear considerable 

 resemblance to this. On the other hand, we have led botanists into error by 

 Dr. Greville and myself having figured tiiis with the venation of an Euasplenium. 

 I trust the present description, and our figure in ' Icones Plantarum,' will have 

 rendered this species intelligible to botanists.

 pinna broad subrhombeo-ovate acuminate equilateral some- 

 times subhastate with unequal lobes, veins dichotomous ob- 

 lique free near the slender costa, anastomosing with oblong
