one solely by a character which is diametrically at variance with the author’s 
description ; but if this character be not maintained there is nothing 
whatever, either in the plant itself or in the description, to warrant its 
separation from O. lancifolium. It is quite possible that it may simply be 
that, and that the capsule I have examined may be an abnormal one in the 
peristome ; but the matter can hardly be cleared up except by further 
examination of the type material or by duoncens of the plant in the 
field. 
The original plant was gathered on Banks Peninsula.

Plants usually in rather dense tufts, with the leaves often somewhat 
crisped when dry, and the ribbed capsule conspicuously exserted on a long 
seta. 
A rather variable plant in aes &e., as mentioned under O. lancifolium, 
and having the calyptra either quite glabr ous or somewhat hairy on the 
same tuft; but fairly well dispasshable by the longly exserted capsule, 
and from the taller allied plants by the striate theca and compact tufts ; 
from the smaller Pulchelloid species by its larger size ; the broad processes 
and the pale colour of the outer teeth are also strong characters, as well as 
the aoa and structure = the leaves. The vaginula is hairy. 
the nea of its own genus ; in fact, the larger size, wider and less crisped 
leaves, and less —_ calyptra are almost the ae cealgse eres 
characters. The yee entirely the form and structur 
but the stomata are nines d on the surface of the theca, and a aaak 
to the neck, and this seems definitely to relegate it to Orthotrichum, 
otherwise the race distinction between the genera disappears If 
hybridization were a more frequent BOTH in the Bryophytes, one 
would be tempted to gpa that O. tasmanicum might be the product of 
fertilization of Ulota lutea by O. lancifolium. 
I have compared O. lateciliatum (original specimen, New Town Rivulet, 
fasmania, ex herb. agape h) with O. tasmanicum, ordi though at first 
nicum, 
abundant material of Gunn’s No. 1629 in Herb. Wils., the type of 
O. tasmanicum, is absolutely identical in habit and other characters 
with Venturi’s plant. Venturi probably only had the smaller forms of 
O. tasmanicum with less striate capsules to compare. 
O. tasmanicum would seem to be a widely distributed species. 
* Published as O. lateciliatum, but Paris’s orthography would appear to be more
