﻿798 APPENDIX. 8. HYMENOPHYLLUM. 



(29^) H. caiiipanulatuiii, Christ, Philipp. Journ., II, 155. 



Densely caespitose. Rhizome slender, but firm, branched. Stipes + l^.^ 

 c.M. long, slender, black and hispid with rigid hairs, as is the rachis. Fronds 

 + 4 c.M. long, ± 1 c.M. broad, oblong, narrowed at both ends. Pinnae + 

 6 on each side, arcuate-reflexed, + 1 c.M. long, flabellatipartite with 4 — 5 

 linear lobes hardly 1 m.M. broad and sparingly aristate-serrate. Texture ra- 

 ther rigid; colour fuscous. Sori few, placed near the base of the costae, 

 stalked; indusium campanulale, the valves ovate, entire. — General habit of 

 H. tunbridgense, Sm. 



Negros. 



(olff) H. ilerrillii, Chwist, Philipp. Journ., II, 154. 



Rhizome creeping, filiform, caespitose, sparingly clothed with short, red- 

 dish-brown hairs, as are the stipes. Stipes filiform, ± 5 c.M. long. Fronds 

 ovate, + 6 c.M. long, + ?> c.M. broad, acuminate, narrowed at the base, the 

 rachis sparingly hairy, not winged. Pinnae close, ± 8 on each side, cuneate- 

 ovate, higher acute, sessile, not adnate, lower stalked, + 6 m.M. broad, deep- 

 ly pinnalifid. Secondary segmenis cuneate, obtuse, ± 3 on each side, deep- 

 ly incised. Lobes lanceolate, flat, ± 2 m.M. broad, serrulate-dentate. Texture 

 rather rigid; colour black-brown. Sori ± 5 — 4 on each side, solitary on the 

 pinnae, occupying the lowest anterior laciniae; indusium ovate, the apex 2- 

 valved, the valves sei-rulate; receptacle much exserted.

A form gathered in Johor State (Malacca), which may be a narrow inter- 

 mediate between this species and H. multifidum, Sw. has the fronds 5 — 8 

 c.M. long. 1 '/i — 2 c M. broad, the main rachis flexuose, sparingly piloso-palea- 

 ceous below, winged above, the wing entire. Pinnae erecto-patent, pinnatifid, 

 the segmenis linear, simple or forked, the ultimate lobes 2 — 5 m.M. long, 

 under 1 m.M. broad, serrate, the serratures rather distant. Indusium ellip- 

 tical, whether or not exsei'ted.
