THE SOUTHERN LIMIT OF ENGALYPTA LACINIATA 
Ralph S. Nanz 
In the revision of the North American species of Encalypta by Dorothy 
Coker in the November (1918) number of the Torrey Botanical Club Bulletin 
the southern limit for Encalypta laciniata (Hedw.) Lindb. [E. ciliata (Hedw.) 
Hoffm.] in the eastern United States is given as northern New York, presumably 
the Adirondack Mountains. While the range given in the revision is the normal 
one, it seems worth while to record the appearance of this species elsewhere. 
Evans and Nichols, in the Bryophytes of Connecticut (1908), report it from 
Branford, Connecticut, collected by J. A. Allen in 1881. This Encalypta was 
found in 1884 by the late Prof. G. F. Atkinson in Enfield Ravine, Ithaca, 
and since then has been collected several times in the same ravine by others. 
The moss was collected from vertical limestone cliffs. 
Although there are a number of ravines of a similar nature near Ithaca, 
E. laciniata has been found only in the one ravine mentioned. For this reason 
no very logical explanation can be given for its occasional appearance so far 
from its natural habitat.

Encalypta. A Revision of the North American Species by Dorothy Coker 1 
In connection with our studies for N. A. Flora , a critical revision of this 
genus became necessary, as the modern conception of its rank and relations to 
the Tortulaceee differs materially from that of the older authors. It is now rec- 
ognized as distinct not only from the “ Pottiacecs,” where it has generally been 
placed, but is known to be intermediate between the Haplolepidece and Dip- 
lolepidecB, having the peristome characters of both groups represented in various 
species; hence it has been placed by Fleischer in a new group known as the 
Heterolepidece. 
A critical comparison of typical and authentic material from North American 
and European herbaria has enabled us to r educe the 18 species recognized by 
Paris’s Index , Brotherus and Kindberg to 8, extinctoria, rhabdocarpa, alpina, 
laciniata, apophysata, brevicolla, procera, and contorta. Only one species still 
remains doubtful, E. lacera Ren. & Cardot., specimens of which were not avail- 
able for critical comparison. All of Kindberg’s species, based on Macoun’s 
collections, prove to be either wrongly described or based on false premises, as 
indicated by me in some notes on this genus. 2 One new varietal combination 
E. laciniata microstoma (Schimp.) Coker occurs in this revision. Miss Coker
