﻿832 APPENDIX. 67a. hemigramma. 



dense roselle, 7 — 25 c.M. long, 3 — 10 c.M. broad, oblanceolale, acute or obtuse, 

 the edge entire or repand to irregularly undulate or incised, the lower part 

 broad or contracted, the base cordate (var. Teysmannii), rounded or acute. 

 Texture varying from membranaceous to subcoriaceous ; surfaces naked; costa 

 sometimes scaly like the rather short stipe; main veins distinct, not reaching 

 the edge; areolae copious, irregular, with few or many free veinlets. Fertile 

 fronds linear-lanceolate or ligulate, 5 — 15 c.M. long, 3 — 12 m.M. broad, nar- 

 rowed gradually to the apex and a stipe 5 — 15 c.M. long, the edge subentire, 

 irregularly repand or interrupted. — Exceedingly variable. A form gathered 

 in Borneo by Dr. Hallier (no. 1822), determined by Dr. Christ has the sori 

 decidedly acrostichoid. 



War. major: Stipes of barren fronds to 16 c.M. long, scaly, the scales 

 subulato-setiform, black. Barren fronds varying from simple to pinnate; pinnae 

 + 3 on each side, connected by a narrow wing. Fertile fronds contracted; 

 pinnae ± 2 on each side, ± 5 c.M. long, ± 3 m.M. broad. Texture herbaceo- 

 Diembranaceous, nearly diaphanous. — Leptochilus latifolius, C. Chr. is distin- 

 guishable from this by its firmer texture, not diaphanous, its colour, black 

 when dry, its often proliferous fronds. 



Malm/ a; — var. major: Luzon, Mindanao.
