52 ADIANTUM. 



N. Zealand, Colemo. — A species apparently very common about Port Jack- 

 son, but I have not received it from any other locality or country, save the 

 solitary one p^iven l)y Mr. Colenso. It is a large (3 feet high) and very dis- 

 tinct species, very compound in its ramifications, and easily distinguished 

 from the two loUowing (A. Cunnhic/hami and A. fulvuni) by tlie position 

 and form of the involucres, here terminating a lobule and oblong, curved or 

 approaching to reniform ; in those siiuated in a sinus and rotundato-reni- 

 form, or orbicular-cresceut-shaped with a deep rounded notch or sinus. 



107. A. Cunni/tghawi, Hook.; frond (8 — 10 inches) deltoid 

 subpedatcly tvi- quadripinnate, secondary pinna3 lanceolate, 

 pinnules rather small cliartaceous glabrous olive-brown very 

 glaucous beneath dimidiate broad oblong obtuse often sub- 

 rhomboid obliquely cuneate, superior base truncate upper 

 margin and round the obtuse apex lobed, lobes emarginate 

 obtuse, sinuses of the lobes soriferous, sori numerous rather 

 large 7 — 10 on a pinnule, involucres orbicular-cordate with 

 the sinus deep and narrow, stipes smooth elongated and as 

 well as the flexuose rachis everywhere ebeneous glossy and 

 quite glabrous. (Tab. LXXXVI. A.) A. formosura, All.

Hab. N. Zealand, Northern Island, A. Cnnnvujham, Sinclair, Colenso 

 {nos. 1670, -iOar, 2045 and 6), J. D. Hooker, ^-c. ^c.—T\ns is a well-marked 

 species of the same group, as to habit, with the foregoing and following 

 one ; but the pinnules are always larger, more generally oblong, very glau- 

 cous beneath, the sori larger, and always placed in a notch of a lobe of the 

 margin (not in the sinus between the lobes, nor from the apex of a lobe), 

 the stipes is quite smooth and the rachis is everywhere perfectly glabrous. 

 Numerous specimens gathered at different periods are quite uniform as to 

 the above characters. The fructifications are very conspicuous on the glau- 

 cous surface of the pinnules from their dark brown colour with a pale mem- 

 branous margin, giving the edge of the pinnule an ocellated appearance. 

 — Caudex very long, creeping, as thick as a goose-quill. 



108. k. fill cum, 'Rd,on\\ frond (1 foot) ovato-deltoid sub- 

 pedatcly tri- quadri- pinnate, secondary pinnoe lanceolate 

 acuminate, pinnules rather small chartaceous bright olive 

 green subglossy glabrous or pubescenti-hirsute (never glau- 

 cous beneath) dimidiato-oblong obtuse obliquely cuneate at 

 the base (usually broadly cidtrilbrm) rarely subfalcate supe- 

 rior base truncate superior margin and obtuse apex lobed the 

 lobes emarginate obtuse, sinuses of the lobes soriferous, sori 

 numerous rather large 8 — 12 on a pinnule, involucres orbi- 

 cular-cordate with the sinus deep and narrow, sti])es very 

 scabrous almost muricidate, rachis also scabrous and downy 

 with fulvous hairs. (Tab. LXXXV. A.) A. fulvum, Raoul,
