MUSCINEiE. 
The new species in this section are B. purpurascens , Br. and 
Sch., and B. fallax, Milde, both belonging to the lacustre group, 
but differing in the margined leaves. B. purpurascens has a pale 
capsule on a short seta, and is synoicous, and B. fallax a brown 
capsule and long seta, and is dioicous. 
III. Eubryum , leaves erecto-patent, free endostome, with 2-4 
appendiculate cilia. 
In this section Bryum bimum , p. cuspidatum , Br. Sch., becomes 
B. affine, Lind., and B. cirrhatum, Hornsch., is reduced to a variety 
of B. affine. B. Barnesii, Schimp., is regarded as a form of B. 
argenteum, L., starved by growth in sand. B. alropurpureum is 
changed to B. bicolor, Dicks., and B. apiculatum, Wils., to B. 
Mildei, Juratz. 
One new species occurs in this section, B. rubens, Mitten, which 
differs from B. erythrocarpum in its margined leaves with wider 
cells. From the species with margined leaves it differs in the 
leaves not being twisted when dry, and in the dioicous in- 
florescence. 
The illustrations in this very difficult genus are given with 
great fidelity, except, perhaps, in the case of the mature capsule of 
B. crudum and the unripe capsules of B. bicolor and B. murale. 
In the latter two the characteristic form is very distinctive, being 
markedly pyriform in B. murale and ovate with the broad end 
nearest the seta in B. bicolor. 
It would considerably increase the value of this indispensable 
work if the author would ascertain from collectors of specimens 
the characteristic features of the growing plants, and record them. 
Thus in Bryum calophyllum the beautiful red tint of the stems 
distinguish it at sight from B. Warneum, which fruits at the same 
date, and B. Marratii may be looked for in vain in August, when 
the two last-named species are in mature fruit, B. Marratii not 
being mature until about November, although all three species 
grow in damp flat hollows among sand-dunes. 
The microscopical and bibliographical work is so full and so 
thoroughly well done that a feeling of regret is experienced on 
finding so little of the natural history of the plants themselves, 
especially in a group of mosses in which information of that 
kind would prove of exceeding value.

Musci Zunnanenses. E. Bescherelle (Ann. Sci. Nat Bot., tom.xv., 
No. 1, p. 47, 1892) gives an account of a collection of mosses made 
by the French Missionary, M. l’Abbe David, in China, between 26° 
and 27° N. lat., the principal localities being Tapintze, Hokin, and 
Lake Tali. Many common European species occur, or are replaced 
by very closely-allied species, whereas, on the other hand, many 
genera and species that are widely distributed in Europe are 
entirely absent (as Gymnostomum, Weisia , Dicranella, Camphy- 
lopus, Atrichum, Polytrichum , etc.), others being represented by one
