Hab. On earth, Waitakarei Hills (Murray, No. 48). 
Well characterized by the size of the cells and the rigid. fragile, stoutly 
cuspidate leaves. The only nearly allied Australasian species is Ty. sciophilum, 
C. Muell., which is а much smaller, more delicate plant, with small leaves and 
smaller cells.

TRIGUETRELLA PAPILLATA (Hook. f. & Wils.), Broth. Waitakarei Hills 
(Murray, No. 20). The fruit of this moss is very rare, but immature fruit 
was sent me recently from Opaki, Wairarapa, North L., gathered in Aug. 
1910, by Mr. Gray. 
BARBULA AUSTRALASIA (Hook. & Grev.), Brid. Mauriceville, Wairarapa, 
North 1., 1910 (Gray, Nos. 41, 71), c.fr. The South Ameriean plant which 
has figured under the same name is very near, but not identical; the cells 
are laxer, less incrassate, more quadrate, the capsule narrower, and the lid 
shorter. The true name for that plant appears to be B. Poeppigiana, C. Muell. 
The New Zealand plant however itself shows some variation in the length 
and form of the capsule.
