ELIZABETH G. BRITTON 
AFRICAN MOSSES 
The Botanical collections made by Dr. Mildbraed for the German 
Central- African Expedition of 1907-1908 are being published in 
Leipsig and a separate including the miosses by V. F. Brotherus has 
just been received. It is part of volume 2 of Botany and contains 
pages 136-176 with 15 plates, including figures of 45 new species. 
The collections contained 137 species of which 57 are described as 
new and one new genus Leptodontiopsis. Of ubiquitous and common 
mosses the following are familiar: Ceratodon purpureus, Hedwigia 
albicans, Siereodon cupressiformis and 12 others from the higher mount- 
ains are common in the colder regions of the northern hemisphere. 
But most of them are quite unknown. Besides the mosses 233 new 
species of flowering plants and 49 hepatics have been described, also 
many new birds, reptiles and mammals. The expedition was led by 
Adolf Friedrich, Duke of Mecklenburg, whose very inteiesting 
volume entitled “In the Heart of Africa” has just been translated 
into English. It has a great many illustrations and states that 3466 
botanical specimens were collected which have been deposited in the 
Royal Museum at Berlin and published by the Royal Prussian 
Academy of Sciences.

EXOTIC MOSSES 
Part 2 of Die Auss-Europaischen Laubmoose by Dr. George 
Roth'^ was received on January 28th, 1911. It contains pp. 97-192 
with plates 9-16, including the completion of the Key to Archidium 
with descriptions and drawings of 25 species, all but one from orig- 
inal specimens, but of these three are American: A. ohioense,\ A. 
Ravenelii and A. longifolium, and of the latter the fruit was not seen. 
So that as far as American specimens are concerned we are not much 
better off than we were before. 
The cleistocarpous mosses are next described under the 8 families 
where they have been placed by recent authors Of Bruchia he lists 
and figures 28 species, all but 10 of these from original specimens, 
but again the treatment of three American species is most unsatisfac- 
tory; 9 of the drawings are not from original specimens, and he per- 
petuates the old mistake of confusing B. brevipes Hook. [B. elegans 
HschJ from Cape of Good Hope with B. Drummondii Hpe. (R. 
brevipes Hook. & Wils. ) and figuring the American specimens instead 
of the African under both names, in neither case from type specimens 
and without Indicating any specific differences between them.
