Nord-Amerika gesammelten neuen Arten, Varietaten und Fprmen der 
Laubmoose, Torfmoose und Lebermoose. This was afterwards included 
in an article in Hedwigia, with considerable more matter added in explana- 
tory notes, discussions of geographical distribution and other kindred topics, 
together with a complete list of all the species of mosses collected and their 
respective localities. This is entitled, Nordamerikanische Laubmoose, 
Torfmoose und Lebermoose, gesammelt von Dr. Julius Roll in Darmstadt 
(Hedw, 32:181-321, 1893). As a Separat-Ausdruck aus “Hedwigia,” 1893, 
Heft 4, it may be obtained in a thin volume, and is the one I use in work 
with the mosses of the region. 
The material obtained was divided for work among several bryologists, 
mostly specialists in some of the groups their labors covered. The 
Hepaticae, about 35 species, were elaborated by Dr. Stephani, of Leipzig. 
Two new species were made, Madotheca Roellii, Kitchelos Lake, Cascades. 
Wash,, its range since considerably extended both north and south,* * and 
Marchantia Oregonensis, Mount Hood, Oregon. This is not considered 
specifically distinct by Dr. Marshall A. Howe in his Hepaticae and Antho- 
cerotes of California (Mem. Torr, Bot. Club, 7: 62. 1899), but only a 
peculiarity of M. polymorpha, as the distinctive character adduced, mainly 
the spiny and toothed appendages of the ventral scales, are not held to be of 
specific worth. Dr. Roll naturally had the Sphagna for his part, taking 
occasion again to bring out his views of grouping them in a natural series of 
forms and varieties under certain specific heads, mainly those most 
commonly recognized. Twenty-seven new varieties were made, and a numer- 
ous progeny of forms, very bewildering when one tries to match them with 
specimens. One feels that a new set would do just as well for almost any 
region. Roll's contribution, with two plates in illustration, takes up a 
fourth of the article in Hewigia 
The other mosses, Laubmoose or Leaf-mosses, as the Germans call them, 
have 27 new species, 3 new subspecies and 17 new varieties. These will be 
found incorporated in the appendix to the “Analytic Keys to the Genera 
and Species of North American Mosses,” by Barnes and Heald, Madison, 
Wis,, 1896, except the new varieties of sphagna made by Dr. Roll. The 
P leurocarpi vjQTQ assigned to Renauld and Cardot. In the Acrocarpi'Dr. 
Carl Muller, of Halle, had the Gr'tmmiaceae, Dr. Venturi, of Trent, the 
Orihotricheae , Dr. Brotherus, of Helsingfors, the rest, except such as fell to 
Professor Barnes, then at Madison, Wis. These comprised the schizocar- 
pous genus Andreaea, all \Ao.cleistocarpi Q.ndi the groups Weissiaceae, Leuco- 
bryaceae , Fissidentaceae, Ceratodontaceae^ Eiistichiaceae . The bibliograph- 
ical record for Prof. Barnes is, Hedw. 32:195-203. 1893. Three new 
varieties of Dicramun Bojijeani De Not {D. palustre. La Pyl, of the 
Manual), were all that were added by him. var. Schloi hewieri, Oregon, 
Washington, Wyoming and Idaho; var. Roellii, Vancouver; var. alaium, 
Chicago, 111 . These appeared in Bot. Centralb. 44: 386. 1890. With the 
exception of Bryum Knowltoni Barnes,* from Newfoundland, they are, as
