I have carefully examined Mitten’s e asperulum at Kew, and am 
confident that it cannot be separated from M. ligulare. 
I have it from both North and South Islands. 
13. Macromitrium pusillum Mitt. in Journ. Linn. Soc., Bot., iv, 78 
(1859). 
This species, which has been omitted by error oie iwi ** Musci,” 
was described from Tasmanian specimens, but t from several New 
Zealand localities. It has the larger, distinct cells a the following plants, 
but is distinct from them in having the calyptra naked.

I have this species from several localities in ate South Island, but it is 
perhaps not one of the more common species. 
17. Macromitrium rigescens Broth. & Dixon in Journ. Linn. hate Bot., 
xl, 446 (1912). 
Near M. erosulum and M. grossirete, but with as branches an 
rigidly appressed leaves when dry. It bears, in fact, to M. grossirete re 
same relationship as M. Petrie: to M. erosulum, and is scarcely distinguish-

I have found several specimens referable to this s species in the her- 
barium of R. Brown from the South Island, but without further locality.
