ASPIDIEJE GYMNOPTEKIS. 43 



stipe of sterile frond 5 to 20 cm. high, of fertile 20 to 40 cm., scaly or 

 glabrescent; sterile frond simple, or with 1 to 3 pairs of pinna, the 

 terminal one lanceolate, entire, repand or subserrate, often elongate and 

 rooting, lateral ones more or less reduced, herbaceous, glabrous; main veins 

 distinct, areolse of various forms, with few or no included veinlets; fertile 

 fronds usually trifoliate or pinnate, 3 to 10 cm. long, lanceolate. This 

 species is well distinguished from the preceding by the venation and the 

 longer, more slender rhizome. This species includes Poecilopteris hetero- 

 clita Presl and P. diversifolia Presl.

(8) G. subrepanda (Hooker) J. Sm. Rhizome woody, wide-creeping; 

 stipe 15 to 30 cm. high, stout, erect, nearly naked; sterile frond simple 

 and 30 cm. long by 3 to 5 cm. broad, or pinnate, and 60 cm. long by 30 

 cm. broad, with several pairs of linear-oblong, entire or subrepand pinnae, 

 subcoriaceous, glabrous; main veins distinct nearly to margin; areolae and 

 included veinlets copious; fertile frond like the sterile, but smaller.

(9) G. repanda (Blume) Christ. Rhizome creeping; stipe 15 to 30 

 cm. high, that of the sterile frond usually the longer, naked; sterile frond 

 30 to 60 cm. long, 20 to 30 cm. broad, sometimes elongate and rooting, 

 with numerous pinna? on each side, the lower ones 10 to 15 cm. long, 

 2 em. broad, cut one-fourth of the way to the costa into entire, obtuse lobes, 

 herbaceous, glabrous; main veins distinct, areolae copious, without free 

 veinlets; fertile pinnae much smaller, stalked, entire or repand. Achrosti- 

 chum Quoyanum Gaud, is a form with the lobes deeper and toothed. This 

 species is construed as including also Poecilopteris sinuosa Presl, Hete- 

 roneuron argutum Fee, and Heteroneurum cuspidatum Presl.

 or scaly below; sterile frond 4 to 8 cm. or more long, usually pinnate, 

 linear to ovate in form, membranaceous, glabrous, the terminal pinna 

 usually elongate, linear, proliferous; lateral pinnae 2 to 6 pairs, lanceolate 

 to orbicular in form, usually entire, sessile, somewhat decurrent; veins 

 inconspicuous, forming few areolae, without included veinlets; fertile frond 

 linear, with 2 to 4 pairs of round or oblong remote pinnae 1 to 4 mm. 

 long, the lowest sometimes stalked, with few or no veins beside the costa.
