Dumortiera velutina Schiffn. in Denkschr. Math.-Naturw. Cl. Kais. Acad. 
Wien, Ixvi. 156, 1899. 
Dumortiera calcicola Campbell in Ann. Bot. xxxii. (1918), pl. 8. £. 9. 
Obs, Prof. Alexander W. Evans, in his latest paper on the genus Dumortiera 
(Bull. Torrey Bot. Club, xlvi. (1919) 167-188), reduces all the known species 
of this genus to two, D. hirsuta (Sw.) and D. nepalensis (Tayl.), the former 
with a smooth antical surface, the latter with a papillose one; all Prof. 
. Compton's specimens belong to the latter. 
The list of synonyms is taken from Prof. Evans's admirable paper.

Prof. Alexander W. Evans, in his paper “The American Species of 
Marchantia” (Trans. Conn. Ac. vol. xxi. 1917), has some useful notes on 
Exotic Marchantia. He reduces M. tabularis Nees and M. cephaloscypha St. 
to synonyms of Berteroana Lehm. & Lindenb. I sent him specimens of Prof. 
Compton’s No. 1807, and he writes :—“ I am much interested in Marchantia 
from New Caledonia. I think that it represents M. Berteroana, and the 
occurrence of this species in New Caledonia would not be surprising when 
we keep in mind its wide distribution in the Southern Hemisphere. It 
seems to me that the appendages in your plant are not absolutely entire, 
but that they show faint crenulations here and there, and I have seen 
appendages similar to yours in material from other localities. I am 
afraid my descriptive phrase, as you imply, is a little misleading. I did xot 
mean to suzgest, however, that every marginal cell projected in all cases, 
but that projecting cells could be found on practically all appendages. It 
would have been better if I had brought out this idea more clearly." The 
appendages of Prof. Compton’s plant are, generally speaking, quite entire, 
marginal cells minute, the cupules acutely lobate, each lobe terminating in a
