in a Clip-like form, with very irregular margins, occupying most of the breadth 

 of the lobes. 



Hab. Sunday or Raoul Island (of the N. Zealand region), Milne & McQllivray. — 

 I give this as a new species with considerable hesitation. It has the deciduous wool of 

 C. dmibata (to which ]\Ir. Moore is disposed to refer it), but the aspect rather of C. ajjinia, 

 of which, however, it wauts the decided prickles. 



54. C. affinis, S\v. ; rachis naked, castaneous ; fr. ample, tripinnate ; 2^inna} 

 o1ilon_i;:-lanceolate 1-1 ^ ft. 1.; jniml. sessile, lanceolate, 3-3| in. 1., |-1 in. br.; segm. 

 lincar-ligulate, ^ in. br., crenato-pinnatifid ; texture rij^idly sul)eoriaceous ; upper 

 surface glabrous, lower slightly furfiiraceous ; veins 10-12-jugate, immersed, 

 obscure, the lowest pinnate in the lobes ; sori costular ; inv. firm, persistent, 

 breaking up irregularly. — Carruth. in Seem. Fl. Fit. p. 333. 



Hab. Polynesian Islands, Forster. — Brackenridge's plant, quoted doubtfully here in 

 the first edition, is C. propinqua. G. extensa of Svvartz, founded on a specimen of For- 

 Bter's not in fructification, may be Alsophila lunulala. 



55. C. Vieillardii, Mett. ; " unarmed ; fr, subcoriaceous, dark-green above, 

 densel}^ hairy, rusty on the costce and rachises, bi-subtripinnate ; prim, pimue 1 ft. 1.; 

 second, ones sessile, ovato-oblong or lanceolate, deeply pinnatipartite, subpinnate 

 at the base, acuminate and obtusely serrate at the apex ; lobes oblong, obtuse or 

 acute, obtusely serrate ; sori at the forking of the veins, intermediate between the 

 costule and the margin ; invol, membranaceous, gradually breaking down and 

 disappearing (fatescens)." — Mett. Fil. N. Caled. Ann. Sc. Nat. Bot. 1861,/). 82. 



Hab. Balade, N. Caledonia, Yielllard. "Near 0. Cunningluimi (Hk. f.), which differs 

 iu being muricated, the lobes sharply serrated, and in the sori being costulai'." — I have 

 seen OLly a small specimen of tbi.s from M. Lenormand's collection. 



Gen. 5. Hejiitelia, Br. (See p. 454.) 



Sori globose, dorsal upon a vein or veinlet. Reccpt. elevated. Invol. a scale 

 situated on the underside of the sorus, varying in size, and shape, and texture, 

 often indistinct, and often very deciduous. — Mostly tropical and arborescent, with 

 the habit of Cyathea ; a connecting link, as it were, between the latter genus and 

 Alsophila, consequently often difficult to recognize. Fronds ample, pinnate, or de- 

 compound. Veins pinnated, simple or branched, free, or, the costal ones especially, 

 more or less anastomosing. Tab. I. f. 5.

1. H. (Euhemit.) Karsteniana, Kl. ; st. muricated and scal}^ at the base ; scales 

 white, dark-brown in the centre ; fr. ample, coriaceo-membranaceous, pinnated ; 

 pinna; sessile, a span to 1 ft. 1., 1^-24 in. w., from a truncated base, elliptical, 

 short-acuminate, quite entire, or more or less lobed at the very margin ; sori 

 (when perfect) in two oblique lines, meeting towards the rachis, and forming a 

 series of the letter V between each pair of costules. — Kl. Bot. Zeit. 12. p. 439 ;

2. H. (Euhemit.) subincisa, Kze.; st. rough, but scarcely muricate ; fr. ample- 

 pinnate ; jyiiDuc remote, subpetiolate, firm-membranaceous, from a cuneato- 

 truncated base, oblong or elliptico-lanceolate, finely acuminate, 10-12 in. 1. by 

 1-2 in. br., the margin inciso-lobate ; lobes 2-4 lines 1., with generally an acute
