100 CRYPTOGAMIA ANTARCTICA. . [Puegia, the 
Nearly allied to D. longisetum, Hook. (Muse. Exot, t. 139), but differs in the more robust habit, leaves longer, 
wider, more rigid, less setaceous above, without serratures, the nerve broader and thicker, capsule longer, peristome 
smaller, the teeth not divided to the base as in that moss.

6, theca and peristome; 7, teeth :—all magnified. 
2 Dicranum? imponens, Mont.; in Voy. au Pole Sud, Bot. Crypt. p. 298. 
Has. Strait of Magalhaens, MM. Hombron et Jacquinot. Hermite Island, Cape Horn; on the hills 
(barren). 
Not having seen original specimens, it is necessary to mention that in the plant we refer to this species, the 
leaves are subsecund and entire; while in other respects they agree with the description quoted. .D. penicillatum, 
Hornsch., to which Dr. Montagne compares his moss, belongs to the genus Campylopus, Brid. 
8. Dicranum robustum, Hook.fil.et Wils.; caule elongato subramoso, foliis falcato-secundis longissimis 
lineari-lanceolatis setaceo-attenuatis convolutis spinuloso-serrulatis, nervo latiusculo excurrente, perichzetialibus 
intimis obtusis enerviis, theca cylindracea inclinata curvula strumulosa, operculo longirostro. D. scoparium, 
B. reflectens, Mont. in Voy. au Pole Sud, Bot. Crypt. p. 997? (Tas. CLII. fig. VILL.) 
Has. Hermite Island, Cape Horn ; in woods, on the trunks and roots of trees, and in the open country, 
growing in large tufts, very abundant. Kerguelen’s Land, Dr. Lyall. 
Caules 4-unciales et ultra, robusti, parce ramosi, subinde incurvi, siccitate parum fragiles. Folia conferia, 
6—7 lineas longa, apice setacea, inferne convoluta, superne carinata, margine dorsoque spinuloso-serrulata, viridia, 
inferiora squalida, perichetialia exteriora squarrosa, basi rotundato-ovata, acuminata, interiora erecta, convoluta, 
3-linearia, elliptico-oblonga, obtusa cum mucrone lineari longiusculo, enervia. Vaginula linearis, elongata. Seta 
7-8 lin. longa, crassiuscula, siccitate vix tortilis, rubella. Zheca cylindracea, inclinata, curvula, rufo-brunnea, stru- 
mulosa. Peristomii dentes bifidi, rubri. Operculum theca paulo longius. Calyptra straminea, apice fusca. 
which are more decidedly serrated, less convolute, nerve broader and excurrent, the pericheetial ones much shorter, 
and wholly different in shape, capsule longer and strumose, peristome larger. In general aspect it is not unlike 
the British D. majus, Turn., but is distinguished by the very long and attenuated leaves.

Var. 4. lucidum; foliis aureo-nitentibus falcato-secundis. 
Has. Hermite Island, Cape Horn. Vars. 1 and 4 (barren) on rocks, trunks of trees, and the ground, 
very abundant. Kerguelen’s Land; Vars. 2 and 4, Cumberland Bay, R. M" Cormick, Esq. 
The var. 4 is a very elegant moss, differing in aspect from the other varieties, but we are unable to detect suffi- 
cient characters to establish it as a species.
