40 ORYPTOGAMIA ANTARCTICA. [Auckland and 
J. notophylla it swells much in moistening, and assumes a stout and as it were greasy appearance, from the pecu- 
liar texture of the distended cells. The broad stipules, reaching nearly across the back of the stem, resemble those 
of J. Billardieri, and are as regular and close along the whole plant as the scales of a snake.

24. JUNGERMANNIA diplophylla, Hook. fil. et Tayl.; caule procumbente laxe implexo divaricatim ra- 
moso, foliis distichis arcte imbricatis divaricatis bilobis lobis plica conduplicatis ciliatis v. ciliato-dentatis, 
lobo superiore erecto patente multo minore ovato subacuto substipuliformi, inferiore patente late ovato obtuso, 
stipulis subquadrato-rotundatis bifidis segmentis ciliato-dentatis. (Tas. LXIV: Fig. IV.) 
Has. Lord Auckland’s group; creeping over the caudices of Ferns, rare. 
Caules subsolitarii, vage repentes, v. ceespites laxos planos sub 1 unc. diametro formantes, planiusculi, pro- 
cumbentes, parce divaricatim ramosi, 1 unc. longi, latiusculi, albidi. Folia tenerrima, membranacea, laxe cellulosa, 
pellucida, dense imbricata, pulcherrime ciliato-dentata, valde concava, profunde biloba, lobis valde insequalibus, lobo 
anteriore multo minore supra faciem anticam caulis extenso, stipulam referente; folium superius in sinu concavo in- 
ferioris receptum. 
In some respects this remarkably beautiful species resembles a Gottschea, but it is in reality more allied to the 
genus Scapania of Lindenberg, from whose published characters it differs only in the presence of stipules! From 
what we have seen of the fructification, however, it widely departs from that group. The calyptra, in a specimen 
from M‘Quarrie’s River (New Holland), is globose, destitute of any calyx, surmounted by a truncated style, 
rough with numerous barren pistilla on its surface, and surrounded by scales; the scales are laciniate, the outer- 
most the narrowest, and all enclosed in a triphyllous pericheetium.

Has. Lord Auckland's group; amongst mosses and other Hepatice. 
This little species is probably not uncommon in the high southern latitudes, having been also gathered in 
Kerguelen's Land. 
26. JUNGERMANNIA /enacifolia, Hook. fil. et Tayl.; caule rigido tenui laxe ceespitoso erecto subsim- 
plici flexuoso, foliis distantibus patentibus rigidis tenacibus elliptico-oblongis obtusis integerrimis basi 
angustatis marginibus planis v. recurvis, stipulis conformibus minoribus integris bifidisve. (Tas. LXIV. 
Fig. VI.) 
Has. Lord Auckland’s group ; amongst other Hepatice, mosses, &c., in exposed situations near the 
tops of the hills. 
Cespites laxi, fusco-brunnei v. atri. Caules graciles, vix 1 unc. longi, rigidi, vix ramosi, flexuosi. Folia stipulis 
conformia semper patentia, dura, rigida, opaca, rarius recurva, fusco-brunnea. 
We know of no species with which the present can at all be compared. The leaves and stipules are so nearly 
alike and so regularly stiff and patent, that the stems look pectinated with a triple row of spines, standing at regular 
intervals. This rigidity, combined with the slender habit, is very remarkable.
