(24) HEMIONITIS i.iim.ieus. 



■Rhizome short; stipes clustered, cliatTy, those of the sterile frond much 

 the shorter; fronds in the riiilippiiu' species entire or lobed, with ample 

 base, pubescent; veins cojiioiisly anastomosing, bearing sori throughout. 

 Striking ferns; with a cluster of sterile fronds on the ground, and the 

 single or few fertile ones long stalked. 



(1) H. arifolia (Hurm.) Hcddome. Stipes of the sterile fronds 2 to 5 

 cm. long, of the fertile 2(1 to ."id cm., brown or l)hick, glossy, chafTy tiirough- 

 out; fronds 5 to 7 cm. long, ;{ to 4 cm. broad, entire or nearly so, apex 

 rounded, base deeply cordate, the fertile frond rather the smaller and 

 with more developed basal lobes, coriacous, lower surface chafTy, sparsely 

 unless on the costa and margin; midrib disappearing below the apex, 

 other veins almost invisible; sori forming a fine network over the fruiting 

 surface.

The Philippine plant difl'ers from the Jii<lian in lia\ing narrower frond.s, 

 the sterile shorter stalked, stipes squamulose throughout, and textvire 

 more coriaceous. 



(2) H. Zollingeri Kurz. Fronds clustered in a dense rosette; the 

 sterile nearly sessile, oblanceolate, entire, about 10 cm. long, membrana- 

 ceous; main veins distinct nearly to margin, with copious fine, irregular 

 areoliB between them; fertile fronds linear, slightly repand, 8 cm. long, less 

 than 1 cm. broad, with a stipe .'? to 5 cm. high; sori in 2 to .3 rows, parallel 

 with costa and margin, anastomosing by short cross-bars.

 tip; fronds clustered, the sterile sessile or subsessile, 7 to 17 cm. long,

 crisjied. broad or contracted at the base, pa]ivraeeo-lierl)aeeous, dark green 

 •with light patches, glabrous except for the usually squamulous costa; 

 areolae rather large, with copious free included veinlets; fertile frond on 

 a stipe 5 to 15 cm. high, itself 5 to 10 cm. high, 2 to 4 mm. broad, the 

 lamina often interrupted; soriferous veins 1 to 3 on each side, about 

 parallel to the costa, occasionally anastomosing; entire lower surface 

 early covered by sporangia.
