A very variable species in size and habit, as mentioned above. 
Both species seem widely distributed in New Zealand.

I am fully in agreement with Fleischer (Musci . . . von Buitenz. 
ii, 581) in reducing M. rhynchophorum Hook. to M. rostratum, which is an 
almost cosmopolitan and rather variable plant. He includes M. pse 
rhynchophorum Broth. in sched. (herb. T. W. N. Beckett). This was 
ted from M. rostratum principally on the ground of the dioicous 
it is one which is occasionally found in Indian specimens of M. rostratum 
- without being correlated with other characters. I do not think it is more 
than an abnormality. : 
There is nothing in the descriptions of Colenso’s two species to suggest 
any difference from M. rostratum. The a te setae by which he 
characterizes M. zanthocarpum are quite usual in M. rostratum (see the 
plate in Bry. europaea).

Syn. Hymenodon helvolus C. M. in Hedwig., vol. 36, p. 3382 (1897). 
A delicate little plant of a glaucous green colour, with leaves sub- 
distichously arranged, and little altered when dry, oblong-elliptic, obtuse, 
with a delicate hair-point. The capsule is erect and practically symmetric, 
ovoid, and I think on this account Hypnum Mougeotianum A. Rich. cannot 
belong here, as the Handbook suggests, following the Fl. N.Z.
