great tendency to hybridization of the species in this genus, no less 
than from a quarter to a third of the sheets in every large collection 
being hybrids. 
The paper on Amelanchier was published by Prof. Wiegand in the 
July, 1912, Roopora. Many sheets of beautiful specimens of the genus 
were exhibited and also some excellent photographs of typical or note- 
worthy specimens. 
NOTES ON CONNECTICUT MOSSES,— IV. 
G. E. NicHors. 
For the moss student whose lack of time precludes the pursuit of 
any extensive research along bryological lines there is open a fasci- 
nating field in the intensive study of the mosses within some limited 
area. During the past few years the writer's major interests have 
become of such a nature that the study of bryology has necessarily 
been forced to a subordinate position, and for this reason the little 
attention that it has been possible to give to this subject has been 
restricted almost entirely to Connecticut mosses. The advisability 
of further exploration within this state and of more intensive work 
was pointed out in the introductory chapter to the Bryophytes of Con- 
necticut, and subsequent work has only served to make still more 
evident the apparently inexhaustible possibilities, from a bryological 
standpoint, of the region under consideration. Since 1908 three 
papers on Connecticut mosses have appeared ! in each of which ten 
species new to the state have been recorded, while the present paper 
includes an even longer list of additions. 
SPECIES OF SPHAGNUM NEW TO CONNECTICUT. 
During the past year there has appeared Warnstorf’s long heralded 
Sphagnologia Universalis? In this exhaustive work many new species 
are described while other forms which heretofore have passed as varie-
