18 New and Little Known West-ttimalayan Liverworts. 
and in arranging the figures properly. As stated in a footnote 
(New Phytologist, Vol. 13, p. 217), it was at his suggestion that I 
gave a variety name to the form of Targionia hypophylla met 
with at Mussoorie. 
ADDITIONS AND CORRECTIONS. 
Note on Aitchisoniella. In the first paper of this series the 
existence of the pores of the antheridial chambers in this genus was 
said to be doubtful (New Phytologist, Vol. 13, p. 222). Fresh and 
younger plants have shown since then that such pores do exist 
though they are very slightly raised and are very inconspicuous. In 
this respect, therefore, Aitchisoniella does not differ from the other 
Marchantiales. 
Note on Nomenclature. In the first paper of this series the 
writer gave a list of the thallose liverworts found at Mussoorie 
(New Phytologist, Vol. 13, p. 208). Some of these plants whose 
identification seemed to be doubtful were sent to Professor Stephani 
for determination. He very kindly sent the names of all that could 
be identified, but they arrived too late to be published before now. 
His determinations are as follows:—(1) Riccia discolor is R. liinia- 
layensis; (13) Grimaldia californica is G. indica St.; (18) and (19) 
are Marchantia palmata Nees and M. nepalensis L. et L.; (20) 
Aneura pinguis is A. juussuriensis St.; (25) is Notothylas Levieri 
Schiffner. 
Riccia himalayensis , I think, need not be separated from R. 
discolor. This species is met with in many parts of the Himalayas 
and even lower down on the plains where R. discolor has been found 
by several people at various times. The differences in the two 
forms are probably due to local conditons. 
I sent some specimens of Cyathodium tuberosum to Professor 
Goebel some time ago, and he informed me that my specimens 
were identical with C. penicillatum St. Having myself examined a 
bit of the latter kindly sent by him, I find that this is indeed the 
case. I have not, however, come across any published description 
of this plant. 
Errata. New Phytologist, Vol. 13, 1914, p. 214, line 4 from 
top: for “ Griffithia ” read “Aitchisoniella” ; p. 216, line 2 from 
bottom : for “ there ” read “ here.”
