78 BRYOLOGY OF NEW ZEALAND. 
Campylopodium lineare (Mitt.) Dixon. 
A specimen from Mitten’s herbarium, “ N.Z., Hutton & Kirk, 306,” i 
this species. 
Dichodontium (Pt. II, p. 72). 
I had overlooked, in stating that Dichodontium was unrepresented in 
Australia, the publication of D. Watts Broth. (in Proc. Linn. Soc. N.S.W. 
(1912), xxxvii, 366). That plant, however, a specimen of which I have 
received through the kindness of Rev. W. W. Watts, is, in my opinion, not 
a odontium, but a Dicranella extremely near to and possibly identical 
with my Dicranella adeeb cneed as to the generic position of which—near 
D. clathrata, &c.—there can, I think, scarcely be a doubt. The Australian 
plant has not been foand ¢ in fruit.

leaf-apex is not, however, sufficient to justify specific rank, for on specimens 
of H. perichaetiale, row 4, Campbell’s I., Hb. Hook.,” I find leaves of the 
normal type side by side with—quite as frequently—others with the type 
described for H. nanum, and scarcely differing from the actual leaves of that 
plant. I may add that neither H. Hodgkinsoniae C. M. nor H. Miilleri Hampe 
also referable here.
