HYPOLEPIS. 69 



uate, primary and secondary pinnae ovalo-lanceolate, tertiary 

 ovate obtuse deeply bipinnatifid, primary segments obovate 

 ultimate segments cuspidato-acute, sori solitary on the inner 

 margin of the ultimate segments, involucres evidently formed 

 of a closely reflexed lacinia covering the sorus, stipes as long 

 as the frond and rachises yellow brown slightly asperulous and 

 as well as the midrib beneath hirsute with rather long crisped 

 jointed hairs, caudex very long creeping naked (not scaly).

Hab. Wood of a shaded moist dell, near the summit of Riiahine Moun- 

 tain range, N. Zealand, and only in that spot. Rev. W. Colensn. — None of 

 the present genus has the elegance of the present species, which Mr. Co- 

 lenso has rightly determined to be new. My largest specimens scarcely 

 exceed a foot in height, and the pinnules are far more deeply and beauti- 

 fully cut than in A. antliriscifoUa of Mauritius and the Cape. Here how- 

 ever the fronds are small and rigid and quite opaque. It is most evident 

 in this species that the involucres are formed of the unchanged and reflected 

 lacinisB of the pinnules, bent down upon the sorus. Caudex long and 

 creeping. 



20. H. hostilis, Pr. ; frond triangular-ovate tripinnate, pri- 

 mary pinnae petiolate remote and as well as the secondary 

 ones sessile alternate patenti-divergent lanceolate, pinnides 

 opposite adnate oblong obtuse inciso-pinnatifid, the segments 

 cuneate at the base subfalcate, secondary rachises margined, 

 primary rachis and stipes aculeolate for much of their length.

 in Liniiaa., vi. p. 86. — &. major ; fronds beneath hirsute with 

 crisped subglandular hairs, stipes and all the rachis aculeolate. 



Hab. Hualaga, Upper Peru, Poeppig. Cocos Island, Pacific, Banks. 

 " Habit almost of Dicksonia. Caudex creeping, slender, clothed with 

 brown scales. Stipes a foot and more long, dark brown at (he base. Frond 

 a foot or a foot and a half long, slender, dark green. Sori solitary at the 

 base of the laciniae ; involucre spurious, at length evanescent. Allied to C. 

 repens, which latter differs in the erecto-patent and much broader divisions 

 of the fronds, and in sori being solitary in the pinnules." — A not very per- 

 fect and young, but authentic, specimen of this is in my possession. It 

 has a very close affinity with my H. nigricans : but wants the very large 

 and copious aculei of that species : and seems to hold nearly the same re- 

 lation with that, that my var. B. of H. repens does with the normal state of 

 that plant. 



What I here make var. /3. is perhaps the more perfect state of this spe- 

 cies : the frond is 2 — 3 feet long, of a rich tawny brown colour, more acu- 

 leolate and with the pinnules hairy with crisped and somewhat glandular 

 hairs beneath. 



21. H. Purdieana, Hook. ; fronds rather small ovate-ob- 

 long moderately acuminated thick-membranaceous bipinnate 

 hirsute with viscid tawny hairs beneath, pinnae sessile ovato-
