42 I. — FiLiCES. [Hymenophylhun 



ultimate lobes very narrow, entire. Sori very numerous, terminal 

 and axillary on the segments ; involucres small, ovate ; valves divided 

 to the base, entire or denticulate. 



Synonyms. — H. productum, Kunze ; Trichomanes demissum, Forst. 

 A variety of this species with relatively long stipes and strongly- 

 winged racliis has recently been described by Mr. W. Oolenso as- 

 _H. erecto-alatum. ("N.Z. Inst. Trans.," vol. xi. p. 431.) 



^^ Bistribution. — Fiji, Java, several Polynesian islands, and the 



- Philippines. 



This dark-green, glossy fern grows most commonly on the ground, 

 seldom on tree-trunks unless they happen to have plenty of earth 

 on them. It is easily transplanted, and gives very little trouble tO' 

 the cultivator, being a free grower and accommodating itself to- 

 circumstances more readily than any other species. It is abundant 

 throughout New Zealand. 



14. H. scabrum, A. Rich. 



Rhizome stout, creeping, more or less covered with reddish hairs. 

 Stipes 2-6 in. long, rigid, wiry, covered — as are the rachis and 

 generally the midribs — with rough reddish hairs. Fronds 6-1 8 in. 

 long (sometimes as much as 30 in. in very fine specimens), ovate- 

 acuminate or deltoid, 3-pinnatifid, pinnate below ; rachis winged 

 above only ; lower pinnse lanceolate or oblong, acuminate, divided 

 almost to the rachis into several pinnules, which are again jjinnatifid ;: 

 ultimate segments linear, obtuse, quite entire. Sori numerous, 

 terminal on the lateral segments ; involucres orbicular, divided 

 nearly to the base ; lips toothed. 



Synonym. — Sphserocionium glanduliferum, Presl. 



Distribution. — Confined to New Zealand. In the North Island 

 it ranges from the N. Cape to Wellington, ascending to 2,000 ft., 

 and is very common. In the South Island it extends from Cook 

 Straits to Stewart Island, ascending to 3,000 ft. ; and while rather- 

 rare down the E. Coast, and of local occurrence on the W. Coast, 

 is again common on both sides of Foveaux Straits. 



It is a very easily recognized species, its hairy stipes and rachis 

 forming a most characteristic feature. 



15. H. flabellatum, LaUll. 



A pale-green, glistening, often pendulous species, forming dense-' 

 niatted patches on the trunks of trees ; rhizome long, creeping, wiry, 

 covered with fine brown woolly hairs. Stipes 2-5 in. long, slender, 

 rather rigid, woolly at the base, not winged. Frond 2-8 in. long,. 

 2-3 in. broad, very variable, ranging from broadly ovate to linear, 

 3-pinnatifid, pinnate below ; pinnse close and imbricating, or distant, 

 flabellate, broadly deltoid, divided almost to the rachis into several 

 cuneate-based pinnules; ultimate segments linear, entire. Sori
