1. Hymenophyllum recurvum; frondibus bipinnatis (6-8-pollic), pinnis elongato-recur- 

 vatis, pinnulis dichotomo-pinnatifidis, laciniis simplicibus elongatis integris, soris supra 

 axillaribus solitariis, ind.usiis ovatis (latissimis), rachi stipiteque alatis, caudice filiform i 

 repente. Gaud, in Freyc. Voy. p. 376. 



Colour, a pale delicate green. 



2. Hymenophyllum lanceolatum ; fronde lanceolata (3-pollic. badia) pinnate, pinnis 

 ovato-lanceolatis bipinnatifidis, laciniis linearibus obtusis erecto-patentibus marginibus 

 pilosis, pilis erectis simplicibus solitariis vel subfasciculatis, stipite terete hirsuto, rachi su- 

 perne alata, indusiis subrotundis compressis longe ciliatis lacinias laterales terminantibus. 



This is distinguished by its dark brown colour, the lanceolate circumscription of the frond, with erecto- 

 patent divisions, fringed with upright hairs, and the ciliated, nearly orbicular, iudusia. 



3. Hymenophyllum obtusum; frondibus caespitosis oblongis obtusissimis tripinnatifidis, 

 laciniis (approximatis) linearibus erecto-patentibus, costa marginibusque pilis longis stellatis 

 obsitis, stipite gracillimo hirto, indusiis (in laciniis supremis) terminalibus orbicularibus 

 pilis ramosis dense ciliatis. 



This may be known from H. hirsutum by the longer branched or stellated hairs, which are confined 

 wholly to the midrib and margin. The ultimate laciniae are somewhat corymbose, generally reaching to the 

 same height, so as to give almost a truncated appearance to the outline of the frond.

 1. Octoblepharum albidum. Hedw. 



1. Thysanomitrion umbellatum ? Am. — Schwaegr. 



This has no fruit, and we are doubtful, in consequence, of the species.

1. Neckera dendroides. Hook. Muse. Exot. t. 69. 



1. Hypnum spiniforme. Hedw. 



2. Hypnum proliferum. Linn. 



3. Hypnum Sandvicense; ramis pinnatis, foliis distichis teneris nitidis ovato-lanceolatis 

 falcato-secundis acuminatis concavis undique serrulatis, nervo brevissimo obscuro, capstila 

 brevi-ovata cernua, calyptra juniore apice pilosa. 



This is a small delicate species, in some respects allied to H. clegans, Muse. Exot, and in others to H. 

 ciicinale, but differing by the characters above given. 



Some other of the Hypnoid family are in the Collection, but without fructification, and although pro- 

 bably new species, yet in too imperfect a state to allow us to describe them in a satisfactory manner.— The 

 same may be said of some of the next Order, the Hepaticce.
