compared it with Dicranum leucolomopsis, C. Muell., n. sp., MS. in Herb. 
(Ins. Wairakai, New Zealand), and found it to agree even more exactly with 
that plant. Herr Loeske, however, considers—and I am entirely of the same 
opinion—that D. leucolomopsis cannot be separated from D. Pungentella ;— 
"D, Pungentella ist vielleicht nur eine derbere xerophytischere Form von 
leucolomopsis." I am the more inclined to this view as Mr. Gray's plant 
shows two distinet forms, one taller, more slender and graceful, the other 
shorter, firmer, with more rigid, less graceful foliation, correspondir 
to the two plants of €. Mueller, but identical in structure, and both comit 
from the same station and I believe forming part of the same pateh. 
I should therefore propose the synonymy as follows :—

It has only been recorded hitherto from Tasmania, and as it has not been 
illustrated I have figured it on РІ. 20. figs. 12-14. 
Since the above was written I have received a few fruiting stems from 
Mr. Gray, gathered near Mauriceville in 1907. The sporophyte does not 
present any marked difference from that of D. Billardieri; the only 
distinetion that I have been able to detect is the slightly longer seta, 3 cm 
to 3°5 and nearly 4 cm., while in D. Billardieri Т have never seen it longer 
than 3 em., while it is frequently much shorter.
