120 CRYPTOGAMIA ANTARCTICA. [-Fuegia, the 
plerumque curvatis, foliis crassiusculis laxe imbricatis erectis secundis appressis oblique ovato-rotundatis, 
margine inferiore gibboso obscure sinuato-dentato superiore incurvo basi celluloso. Nobis in Loud. Journ. 
Bot. v. 8. p. 457. (Tas. CLVI. Fig. V.) 
Has. Hermite Island, Cape Horn; on the trunks of trees near the ground. 
Cespites 2-4 unc. lati, rufo-brunnei Caulis + unc. longus, apice strictus v. seepius curvatus, nune hamatus. 
Folia e basi caulis gradatim majora, imbricata, homomalla, compressa, margine superiore incurvo, plica tumida elon- 
gata, inferiore tumido obscure et obtuse sinuato; cellule minime, dense, nisi ad basin foliorum ubi majores palli- 
dioresque evadunt, maculam latam eficientes. 
A species allied to the J. biserialis, L. and L., of Tasmania, but less than half the size, with more minute denti- 
culations to the leaves, which are widely ovate, not round or decurrent at the anterior margin, nor bispinous at the 
apex.

We owe our acquaintance with this plant to the liberality of our learned friend M. Montagne, who most gene- 
rously has communicated to us his own examples of such Antarctic species as we desired for comparison or examination, 
unhesitatingly confiding his unique specimens to the care of the post-office, that we might profit to the fullest 
by his labours, and avoid unnecessary errors. It differs from our J. unciformis in the larger and narrower leaves, 
which are acute and serrato-dentate along the inner margin. 
11. JUNGERMANNIA duricaulis, Hook. fil. et Tayl.; caulibus ceespitosis duris robustis flexuosis erectis 
ramosis, foliis amplis subimbricatis patentibus oblique ovato-cordatis basi decurrentibus argute denticulatis, 
basi postica porrecta verticali, margine inferiore lente recurvo. Nobis in Lond. Journ. Bot. v. 3. p. 458. 
(Tas. CLVI. Fig. IX.) 
Has. Hermite Island, Cape Horn; abundant, in the woods. 
Species insignis. Czespites laxi, majusculi; externe pallide sed luride olivacei. Caules 4 unc. longi, irregula- 
riter ramosi, ramis compressis. Folie 4 unc. longa, arcte laxiusve imbricata, marginibus dorsalibus parium sub- 
oppositorum rotundatis postice porrectis appressis carinamque cauli quasi efficientibus ; margine superiore paulo 
incurvo, marginibus omnibus minute sed creberrime et regulariter denticulatis. Perigonia in spicam brevem termi- 
nalem disposita. 
Most nearly related to the PZ. flaccida, Lindb., of St. Vincent, which has a very similarly hard and woody 
stem but the present may be known by the greater breadth of its branches and foliage, by its more compound ramifi- - 
cation and the minute denticulation of its leaves.

We have seen no Fuegian specimens of this species. Those M. Montagne has examined, are in a very unsatis- 
factory state.
