The genera are those of the tropics with little or nothing startling in the 
way of odd or ancient types. Leucoloma is credited with 38 species, Campylopus 
with 28, Fissidens with 25, Bryurn with 24, Calymperes with 22, etc. Sphagnum 
with 17 (p. 7) is noteworthy, even though the list is reduced by 3 and other- 
wise somewhat altered in a supplementary note (p. 54) resting upon a change 
of mind of Warnstorf. The genus Cardotia Besch. and the new one, Porotrichella 
Card, (type-species Porotrichum scaberulum R. & C.), are endemic, but their 
status as genera remains to be established. 
The text contains various nomenclatorial observations of interest and some 
new applications of priority. Occasionally (pp. 154, 204) one is struck by an 
unaccountable refusal to make use of the priority duly pointed out. As to 
genera and the whole systematic arrangement the junior author is for better 
or worse pretty much wedded to Brotherus’ system in “Die natiirlichen Pflanzen- 
familien.” He substitutes, however (pp. 225 f.), on grounds of priority the 
generic name Diplostichum Mont, for Eustichia, asserting that the latter should 
then replace Bryoxiphium. For similar reasons (pp. 230 f .) Leiomitrium Mitt, 
replaces Coleochaetium. The opinion (p. 130) that the Pilopogons of tropical 
America are generically distinct from Thysanomitrium is also worthy of note. 
The plates are good, but suffer somewhat in their interpretation and use 
from the fact that they were prepared so long before the text; the text-volume 
must be constantly used with them. Many species are not figured at all, while 
on the other hand some figures are of species not found in Madagascar. The 
latter are sometimes included for comparison, sometimes because they might be 
looked for on the island. In a few cases American forms are thus included, 
two West Indian Leucolomas, for example, by mistake (p. 102). 
The extremely high price and the limited edition represent a direction 
hardly calculated to make science safe for democracy.

NOTES ON RECENT BRYOLOGICAL LITERATURE 
We have already noted in the last volume of The Bryologist the begin- 
ning of Father Luisier’s articles upon the Mosses of Madeira. In continuation 
of the series, recent issues of Broteria 1 contain the detailed catalogue of the species 
from Sphagnum to Barbula, inclusive. Besides the critical notes on the species 
and the citation of previous publications, careful descriptions are given of all 
those species which are not described in current European manuals, and, in 
the accompanying plate, the details of certain species of Fissidens and Leuco- 
bryum. There is one new combination, Campylopus Tulgreni R. & C., being 
reduced to a variety of C. polytrichoides de Not.

1918).
