A large genus of tropical and sub-tropical mosses, in vegetative 
characters very similar to Stereodon, though usually with the stems 
more ereeping and more regularly, often edly pinnate; the 
small turgid, S aatilly urceolate and symmetrical, Ascott capsule, 
with very shortly rostellate lid, is the main character. On t 
hand, there is often a close resemblance, almost transition, okboe 
this genus and Isopterygium, as mentioned under Isvteryiisin 
molliculum.

Voy., Bot., p. 109 (1841); Handb. N.Z. FL, p. 477. 
A rare species in New Zealand, very similar, vegetatively, to 
slender forms of Stereodon chrysogaster; usually pale or golden 
yellow in colour. From that species it may be distinguished by the 
filiform subula of the leaf being sg vsighsingh distinetly Soriicatats, 
while in S. chrysogaster it is entire; by the narrower leaf base, and 
the absence of the alar group of rounded els so characteristic of

but these do not always occur, and when present may easily be left 
on the stem unless the leaves are very davctally removed. 
n in fruit it is known at once by the autoicous inflorescence, 
the shorter seta—about 1.5-2 em., rarely over—and the pendulous, 
symmetric, oblong or oval-oblong capsule. The colour, the strongly 
tae ata leaves sei acenteniate subula will distinguish it 
from Isopterygium mollicul 
It occurs, on trees, in pak Islands, but is very rare.
