Since the publication of the species, however, further material has 
become available from Brown’s herbarium. specimen labelled

The eo, not or scarcely striolate at base, but papillose 
throughout, bring this moss very close to Dicranoweisia. ‘In form, 
peristome. On the other hand, the divided teeth preclude its being placed 
sas the subgenus H olodontium, and the inflorescence, which appears 
dioicous, would also remove it from that section. I propose 
spabetor, for it the new subgenus Trichodontium, having the pri rincipal 
characters of Holodontium but differing in the finely bifid, papillose 
peristome-teeth, and “gies in the dioicous inflorescence

one ee aole “Middle Island, Otago; Hector and Buchanan.” I have it 
also from Paparoa Range, 1888, R. Helms (the same plant which 
C. Miiller described as Dicranum ealeiaion a n.); and from Clinton 
Valley, Te Anau, collected and sent by D. Petrie. There is a single speci-

the British eiecus collection. It would appear to be a rare plant. It 
occurs in R. Brown’s herbarium as Trichostomum Hallii sp. nov., collected 
by Brown by Lake Te Anau, on decaying wood, in 1890. A further 
interesting extension of its range is given by a specimen in Mitten’s 
an; 790. Nov., 1846,” which is quite identical with the New 
Tealitid we. trichopodum. 1 have also received a Tasmanian specimen 
recently collected by Mr. IL. Rodway (No. 1705).
