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

 of the lobes. 



Hab. Sunday or Eaoul Island (of the N. Zealand region), MUne & McGilivray. — 

 T give this as a new species with considerable hesitation. It bas the deciduoaa wool of 

 C. dealbala (to which Mr. Moore is disposed to refer it), but the aspect rather of C. affinis, 

 of which, however, it wants the decide^ prickles. 



64. C. affinis, Swr. ; raehis naked, castaneous ; fr. ample, tripinnate ; pinruB 

 oblong-lanceolate 1-1^ ft. 1.; pinnl. sessile, lanceolate, S-SJ in. 1., f -1 in. br.; segm. 

 linear-ligulate, | in. br., crenato-pinnatifid ; texture rigidly subcoriaceous ; upper 

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

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

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



Hab. Polynesian Islands, Farster. — Erackenridge's plant, quoted doubtfully here in 

 the first edition, is 0. propinqita, 0, exteasa of Swartz, founded on a speoimen of Por- 

 ster's not in fructification, may be Alsophila Vimvlata. 



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

 densely hairy, rusty on the costce and rachises, bi-subtripinnate ; prim, pinnce 1 ft. 1. ; 

 seco-nd. 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. Ualed. Ann. Sc. Nat. Bot. 1861, p. 82.' 



Hab. Balade, N. Caledonia, Vieillard. " Near C. CunningJiami (Hk. f .), which differs 

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

 seen only a small specimen of this from M. Lenormand's collection. 



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



Sori globose, dorsal upon a vein or veinlet. Recept. 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 scaly at the base ; scales 

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

 pinn<B sessile, a span to 1 ft. 1., I5-25 in. w., from a truncated base, elliptical, 

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

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

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

 Mett. F. H. Lips. p. 111. t. 29. /. 1-4. 



Hab. Caracas, Sarsien, Pendler, n. 386 ; Funck, n. 769. 



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

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

 truncated base, oblong or elliptioo-lanoeolate, finely acuminate, 10-12 in. 1. by 

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