MOSSES OF NEW ZEALAND. 451 
?THUIDIUM pENTICULOSUM (Mitt), Jaeg. Mt. Cook district (Murray, 
No. 97). А pretty little plant, mostly of a golden-green colour, seems to 
belong here, from the description, but I have not at present been able to see 
an authentic specimen of Mitten's plant. Dr. Brotherus writes that he has 
not seen Mitten's species and cannot therefore form an opinion of its identity 
with that. It resembles T. leviuseulum (Mitt.), but has the nerve not cristato 
at the back, and the tips of the branch-leaves straight and not incurved. 
HYPNACGCELJE. 
AMBLYSTEGIUM RIPARIUM (Linn.), Bruch & Schimp. In mud at the bottom 
of creek, Hunterville, north of Marton, North 1., alt. 800 ft, Nov. 1905 
(Burgess, No. 26). There can be no doubt of the identity of this with our 
A. riparium, of which it is an ordinary aquatic form. It has previously 
only doubtfully been recorded from Hawke's Bay (Colenso), cf. Handb. of 
N. Z. Flora, p. 482, and it is interesting to have its presence established. 
Although a fairly cosmopolitan moss, it does not appear to have at all a 
general distribution in the South Pacific. 
DnEPANOCLADUS BRACHIATUS (Mitt.). Mt. Cook district (Murray, No. 79); 
Kaipara, near Auckland, North I., 1904 (Blackwell, No. 38). This plant, 
which apparently does not find a place in Brotherus’ work, varies somewhat 
in size and habit, serrulation of leaves, and basal areolation. 
D. rtLvrrANs (Dill), Warnst. Mt. Cook district (Murray, №. 82). A 
form somewhat intermediate between the groups Amphibium and Fuleatum, 
having the habit of the former, but incrassate orange ајаг cells and a rather 
wide nerve. 
D. uxcixATUS (Hedw.), Warnst. Mt. Cook district (Murray, No. 105, st.; 
No. 122, c.fr.). 
ACROCLADIUM CHLAMYDOPHYLLUM (Hook. f. & Wils.), Broth. Mt. Cook 
distriet (Murray, Nos. 74, 108). 
CamMPYLIUM RELAXUM (Hook. f. & Wils.), Broth. Mt. Cook district 
(Murray), g and c.fr. The fruit of this species would appear to be rare. 
STEREODON CUPRESSIFORMIS (Linn.), Brid. — Waitakarei Hills (Murray, 
No. 6), efr. : two slightly differing forms. — Waitakarei Hills (Murray, 
No. 30): a robust, densely pinnate form; leaves solid, acumen broad, 
one margin recurved. 
Var. ELATUS (Schimp.), Mt. Cook district (Murray, Nos. 81, 106). This 
plant agrees very closely with our forms of var. elatus, and I think may 
quite safely be referred there. "The var. elatus has not been recorded from 
New Zealand.
