ve seen no New Zealand specimens of G. pulvinata that I could 
refer e type (most belonging to var. obtusa), nor have I seen any records 
for this form ; the fact that Brotherus includes the above-cited three species 
of C. Mueller’s under the synonymy of G. pulvinata by no means implies 
that they belong to the type; the descriptions in fact make it clear that 
they belong to the variety. 
G. basaltica Mitt. must, I feel confident, be referred her t 
described as differing from G. orbicularis in the more deeply ribbed esula 
with the peristome-teeth reflexed. The leaves in Mitten’s specimens at 
Kew (under the name G. reflexidens),* coll. Lauder Lindsay, are identical 
with G. pulvinata. The peristome-teeth in mature capsules are in several 
cases strongly reflexed against the capsule-wall, though two or three 
capsules have them spreading and yin ot reflexed. In other respects 
the plant does not differ from G. 
e position of the east g RAAL in mature capsules is usually 
spreading almost horizontally. specimen from Brown’s herbarium, 
coll. W. Bell at foot of Lake Wakatipu, and labelled by Bell “ G. basaltica,” 
has the capsules deeply plicate, but the teeth horizontally spreading, not 
> ates n my own herbarium I have Scotch and Irish specimens of 
G. pulvinata with the teeth slightly reflexed, and in one tuft a single capsule 
has them strongly reflexed as in Mitten’s G. basaltica, while the other 
capsules in the tuft are normal. . basaltica must therefore be considered, 
hink, a variety only.
