 deltoid in ;,'eiieral outline, decidedly dimorphous, the barren ones with a 

 narrowly-win^'ed rachis; lower pinna; cut down nearly to the rachis, 

 with deep bluntly-toothed segments; fertile pinna? much more finely divided;

Aneiteum and Fiji. 



This and the preceding three species are decidedly too near together. 

 A fern differing from H. botrj/chioides in lieing less divided grows on 

 Mount Apo, .Mindanao (Copeland 1030). 



(vS) H. falcinella (Presl). Rhizome wide-creeping, thickly beset with 

 stitT, spreading hairs, ferruginous, turning toward black; stipe 5 to 10 cm. 

 high, glabrous, as is the frond; fronds about 13 cm. high, 10 cm. broad, 

 deltoid, tri- or quadripinnatitid ; main rachis slightly winged; lowest pinnsE 

 inequilateral; pinnules oblong, cut down nearly to the rachis into segments 

 which are again deeply toothed, idlimate segments of the fertile frond 

 falcate-mucronate, of the sterile frond broader and not so sharp; texture 

 subcoriaceous ; sori 2 to G to a lobe, placed at the bases of the teeth; 

 indusium thin.

This fern has the aspect of Eudavallia and the palesE of Microlepia.

 the base below, and roundly lobed, with the lobes again crenate above; 

 texture herbaceous; .sori large (2 mm. broad), 1 to G to a segment, oblique.
