above, less distinctly serrated, not fragile, and the nerve ex- 
current. 
56. Hypnum consimile, nov. sp.; caule elongato subramoso 
debili, foliis erecto-patentibus superioribus secundis ovato- 
lanceolatis acuminatis serrulatis striatis nervo subexcur- 
rente. 
Has. Lord Auckland's group. 
Like the last, but with leaves of a different shape, gradually 
tapering to a point, more minutely serrulate, nerve stronger, 
and the areolation more minute. 
57. Hypnum scabrifolium, nov. sp.; caule pinnato, foliis 
laxe imbricatis ovato-lanceolatis acuminatis margine scabris 
dorso papillosis nervo valido subexcurrente. 
Has. Lord Auckland's group, barren. 
Allied to H. crispifolium, Hook.; but smaller, and the 
leaves not plicate nor falcate. 
58. Hypnum hispidum, nov. sp.; caule arcuato ramosius- 
culo, foliis imbricatis falcato-secundis ovatis longe acumi- 
natis plicatis integerrimis nervo crasso longe excurrente, 
seta levi, theca ovata æquali, operculo longirostro. 
Has. Lord Auckland’s group, barren. Described, as to the 
fructification, from New Zealand specimens. 
Apparently amphibious; the elongated aquatic state re- 
sembles Anictangium aquaticum, Hedw. 
59. Hypnum chlamydophyllum, nov. sp; caule ramosiusculo, 
ramis elongatis simplicibus apice cuspidatis, foliis imbri- 
catis patulis quadrato-rotundis obtusis concavis basi trun- 
catis integerrimis nervo breviusculo evanido, seta elongata 
gracili levi, theca ovato-oblonga cernua, operculo conico. 
Has. Campbell’s Island, barren. Described in part from 
Van Diemen’s Land specimens. 
Allied to H. cochlearifolium, Schwaegr. but differing in the 
cuspidate branches, broader and more flaccid leaves, curiously 
widened and truncated at the base, where a number of large 
pellucid cells are visible; the seta also is longer and more 
slender. From H. auriculatum, Mont. it differs in its wider 
leaves. |
