process,” for an example of which he quotes the discolorations 
made by leaves which have fallen on a smooth pavement during 
a rain, which he regards as having “left their impress on the 
stone!” We offer this hint to those who are engaged in the 
study of nature printing processes as valuable. Aude

Sphagna—LEinige neue exotische. C. Warnstorf. (Hedwigia, 
xxxi. 174-182, two plates.) 
One would suppose that this genus had been pretty well ex- 
plored in North America, but here comes Herr Warnstorf again 
with four proposed new species—S. Ladbradorense, from Labra- 
dor, received from Prof. Macoun; S. dasyphyllum, collected by 
Dr. Evans, at New Haven; S. Orlandense, from Florida, re- 
ceived from Prof. Eaton; S. Mohkrianum and S. Mobilense, col- 
lected by Dr. Mohr, at Mobile, Ala.

A new genus Glaucospira, with two species G. agilissima and

This most useful compilation will be of the greatest service to 
all systematic botanists. It gives, in addition to the names of 
plants proposed as new species, the new binomial combinations 
which have been in transfering species from one to another or in 
taking up older specific names, These new combinations are 
distinguished from the new species by the omission of the locality 
from which the plants were derived, It is highly gratifying to 
learn from a foot-note by Dr. Vasey, that it is proposed to make 
such a list an annual feature in the work of the National Herb- 
arium.
