The discovery of a Be fee of this remarkable genus in 
New Zealand is one of the most interesting recent additions to the 
moss flora of the Island. Hitherto the genus has been reateioted 
to the two well-known northern B. aphylla and B. indusiata, with 
three other rare northern species, one in the U.S.A., one in Japan, 
th 
sphere, viz., the Tasmanian B. tasmanica Mitt. The New Zealan 
plant might be expected to be identical with the Tasmanian one, and 
I was at first inclined to refer it there. Most unfortunately Mitten’s 
species is only represented by three specimens, two at Kew, and one 
in Mitten’s herbarium, and these have the capsules unripe and the 
peristome, therefore, as well as the structure of the exothecium, 
uncertain. Careful examination of the specimens, however, reveals 
though Mitten Hanan hes the plant as ‘‘ peduneulo subseabro, 
figures a seta as decidedly papillose at apex. Only imperfect peris- 
tome was seen. 
The i setae of the new species that I possess are respectively 
1.6 and 1.8 em. long, and only .2 mm. in thickness, and are quite 
smooth, and these differences alone, I think, would preclude its being 
referred to B. tasmanica. Further specimens have I believe been 
collected, and it will be Lceierae to ascertain how far the above 
characters prove to be reliable

of the New Zealand plants belong to a southern form 
having ae nerve of the leaf excurrent in a rather marked, serrate, 
pale arista, which in the perichaetial leaves may be co: conspicuously 
prolonged and subhyaline. This form was published by Rehmann 
in his S. African ees as P. ar gaat which I reduced to a variety 
in 8. Afr. Journ. of Sci. xviii, 323, as P. commune var. trichodes
