exiguns Sulliv. For comparison with these there have been furnished from 
the Herbarium of Columbia College, New York City, F. inconstans Schimp- 
Cheyenne Canon, Colorado, 1872; F. B amber geri Schimp., collected by 
Milde at the original station, Meran, Tirol ; F bryoides Hedw. Erb. Critt. 
Ital.; F. bryoides Hedw. from near Durlach, Baden; F. bryoides var. inter-

collected by R. Ruthe, locality not given. This No. 1160 Warnstorf in Kryp. 
FI. Mark Brand. Laubmoose 2 : 171, 1906, gives as F. impar Mitt.). From

and 116238; F exiguus Sulliv. Ex, Musci Allegh No. 84199. The other 
specimens used are of my own collection, the oldest F. minutulus Sulliv. 
Kankakee, Illinois, 1872, determined for me by the late Thomas P. James 
This has been the species most frequently found since, and occurs in exam- 
ples from Minnesota, Illinois and New York. All my other examples, F. 
exiguus , F. inconstans , F. synoicus , F. incurvus Stark, 1807 (=F. incur- 
vus Schwaegr. 1816), are from northern Illinois. 
F. inconstans in the Manual of Lesquereux and James seems to be lim- 
ited to the collection of Wright at San Marcos, Texas. It is the only exam- 
ple cited, and F. synoicus Sulliv. is made a synonym. No reference is made 
to its presence elsewhere as is usual in the case of rare species. The Colo- 
rado specimens were collected by T. C. Porter, July 11, 1872. They are 
labeled “A! inconstans Schimp., Ed. n ( F . bryoides var. inconstans Limpr- 
Laubmoose).” Why it was not referred to in the Manual published in 1884’ 
is not evident. It may have been due to the uncertainty of its standing in 
the opinion of one of the authors, Mr. James, or have been overlooked. The 
following note of his (fide Mrs. Britton) accompanies the specimens: “A. 
Porteri n. sp. provisional. Stems branched, the branch bearing the fruit- 
stalk is attached to the main stem about one-fourth its length. The capsule 
small, oval, almost rotund. The male organs are axillary on the main stem 
(Monoecious). Can it be a hybrid between F. incurvus and F. bryoidesl 
A Fissidens which I cannot specifically separate from this I have twice found 
at a single station at Glenwood, 111 . 
Fissidens inconstans was described by Schimper in 1876 from specimens 
found by H. Boswell near Oxford, England, in 1863 (Synop. Mus. Europ. Ed- 
11, 1 14, 1876.). Its fruit is said to mature in March. Schimper states that it 
is very inconstant in the position of its fruit, which is sometimes terminal, 
sometimes lateral and axillary, the capsule smaller than in F. incurvus , 
“ always suberect or erect.” “ Whether a species near to the very polymor- 
phic F. inctirvus is really distinct or not is doubtful,” he adds. Warnstorf, 
one of the latest authorities, gives it specific rank, grouping it in his Ueber- 
*In the Synopsis of the Flora of Colorado, by Thomas C. Porter and John M. Coulter, 
Washington, D. C., 1874, to which the article on Musci was contributedby Leo Lesquereux, 
no species of Fissidens is given The list includes, among new ones described, those col- 
lected by Porter and others in 1872 and 1873.
