94 HYMENOPHYLLUM. 



lying flat over the surface of the froml. Some of the fronds, it may be ob- 

 served, are wholly pinnatifid, others pinnate below. 



25. II. ccntyivosum, Carm.; clothed with branched tawny 

 hairs, fronds oblong or ovato-aciuninate tripinnatifid pinnate 

 below, jiinnai or jn'imary divisions ovate acuminate subcu- 

 ncatc, the segments close compact often almost imbricated 

 linear obtuse, involucres smaller than the segments semior- 

 bicular the base cuneatc sunk, valves very hairy, stipes not 

 winged. (Tab. XXXIV. A.) — Carm. in Linn. Tr. xii. p-5>7^.

 distant and rather more acuminate. H. Franklinianum, Co-

Hab. On rocks, Tristan d'Acunha, Thouars, Bory, Carmichael — ^. New 

 Zealand, Dusky Bay, Mcnzies. Pendulous on the trunks of trees, Waika- 

 re, northern island, W. Colenso, Esq. n. 272. — Stipes hairy, shorter than 

 the frond, which is 4 — 5 inches lonji:. In the color of the dried specimens 

 there is nothinj^j to justify the specific name. The species resembles small 

 specimens of H. ciliatum; but the lower portion of the frond is clearly pin- 

 nated, and the involucres are different. 



26. H. lanceolatum, Hook, et Arn. ; fronds lanceolate pin- 

 nated, pinme ovato-lanceolate bipinnatifid distant, the seg- 

 ments narrow-linear obtuse erecto-patent, the margins hairy, 

 hairs erect simple or branched, rachis winged above, involu- 

 cres terminal on lateral segments orbicidar almost free cili- 

 ated with long hairs, stipes not winged hairy. (Tab. XXXIV. 

 B.) Hook, et Arn. Bot. of Beech. Voy. p. 109. 



Hab. Oahu, Sandwich Islands, Lay S)- Collie, Douglas, Diell. — A rather 

 small, apparently pendent, species, becoming of a dark chestnut brown 

 when dry, with lanceolate fronds 3 — 4 inches long, erecto-patent, divisions 

 and segments, which are rather distant, fringed with appressed hairs. In- 

 volucres scarcely at all sunk, ciliated with long hairs. 



27. H. Lindeni, Hook. ; large, downy and ciliated (but not 

 densely) with scattered stellated hairs, fronds broadly ovate 

 acuminate bi-tripinnatifid pinnate below, the pinnae or pri- 

 mary divisions lanceolate much acuminated, segments linear 

 obtuse, involucres smaller than the segments semiorbicular 

 the base slightly cuneated and sunk, the margin ciliated with 

 rather long hairs, stipes stout long very hairy especially 

 above, not winged. (Tab. XXXIV. C.) 



Hab. Caraccas, Linden, n. 173. — A large species. Stipes 6—8 inches 

 long ; frond nearly the same, or longer, broadly ovate. The greater size 

 and pinnated fronds and long stipes well distinguish this from H. ciliatum ; 

 iuld to which the fronds are hairy all over, though not densely ; and the in- 

 volucres arc much smaller, not cordate at the base, but rather cuneate and 

 partially sunk in the frond.
