26 CRYPTOGAMIA ANTARCTICA, [Auckland and 
Caules 3—4 unciales, graciles, laxe ceespitosi, parce ramosi; ramis erectis. Folia laxe imbricata ut in H. elon- 
gato, sed multo minora et e basi subquadrata gradatim attenuata, minute serrulata, nervo valido apice incrassato 
subexcurrente instructa, areolis minimis subrotundis v. punctiformibus. 
This moss might readily be taken for a slender state of the H. elongatum, nobis, from which it is truly distinct 
in the lower part of the leaf being subquadrate, angled on each side a little above the base, thence tapering gradually 
to a point, in the margin being more minutely serrated, the nerve stronger, and in the smaller reticulation.

culation :— magnified. 
5. Hypwum scabrifolium, Hook. fil. et Wils. ; caule pinnatim ramoso, foliis laxe imbricatis ovato-lan- 
ceolatis acuminatis margine scabris dorso papillosis nervo valido subexcurrente. (Tas. LX. Fig. VI.) 
Has. Lord Auckland's group; barren. (Dr. Lyall.) 
Caules unciales et ultra, ramis interdum divisis. Folia caulina dissita, patentia, subrecurva; ramulina minora, 
laxe imbricata, erecto-patentia, vix secunda, siccitate incurva, nervo continuo, omnia margine scabra subdenticulata, 
glaucescentia, areolis minimis punctiformibus opacis. 
This is one of the discoveries of my zealous friend Dr. Lyall, the value of whose collection is particularly noticed 
in the preface to this work. The number of mosses and sea-weeds especially, brought home from the Antarctic 
regions, was much increased through that officer’s unwearied exertions. _ 
Nearly allied to the H. erispifolium, Hook. (Muse. Exot. t. 31), but smaller, with the leaves neither plicate nor 
falcate.

Haz. Lord Auckland’s group and Campbell’s Island; in marshy situations. 
There are two varieties in the collection, both of them barren. 
7. Hypsum serpens, L.; caule subpinnatim ramoso, ramulis simpliciusculis filiformibus suberectis, 
foliis patentibus ovatis acuminatis evanidinerviis, theca cernua oblonga, operculo convexo subconico acuto.

Var. 8 ; foliis subsolidinerviis. 
Has. Lord Auckland's group; the var. 8 only. (Dr. Lyall.) 
Except in the more defined nerve, this does not materially differ from British specimens.
