Australia) and New Zealand may be expected to have migrated from 
the former region to the latter, then the following list shows an addition 
of three species to the first category (exclusive of more or less cosmopolitan 
species here recorded for the first time), in plants hitherto known only from 
Tasmania or continental Australia. The five new species described form an 
addition, for the present at any rate, to the extensive endemic flora of the 
Islands ; while in two cases at least—viz. the subgenus Holodontium 
(represented by the new species Dieranum Mackayi) and Dieranoweisia 
antarctica—we have a very interesting addition to the floral links between 
New Zealand and the Antarctic and Fuegian regions. 
My thanks are due for assistance in working out the determinations 
of this list to Dr. Brotherus and Monsieur Cardot, and to the authorities 
of the British Museum and Kew Herbaria. 
I have used the nomenclature and arrangement of Brotherus in the Musci 
(Engler & Prantl, Natürl. Pflanzenfamilien). 
When the plant was found fruiting I have added *c.fr." ; in all other 
cases no fruit was present. 
SPHAGNACEA. 
SPHAGNUM CYMBIFOLIUM, Ehrh. Mt. Cook district (Murray, No. 83). 
S. MEDIUM, Limpr. Mt. Cook district (Murray, No. 84). This species 
has not, Г believe, been recorded for New Zealand, nor, so far as I аш 
aware, has any record been published for Australasia. 
ANDREAACE. 
ANDRE&ZA PETROPHILA, Ehrh. Nun’s Veil МЕ, 6000 ft. (Dr. Mackay, 
No. 132).
