No. 376.] REVIEWS OF RECENT LITERATURE, 295 
Students of South American botany will be interested in the 
Xyridez and Burmanniacez (by Malme) and Oxalidacex (by Fred- 
erikson) of Regnell’s first expedition, contained in volume xxii of the 
Transactions of the Royal Swedish Academy of Stockholm. 
The occurrence of fossil remains of Brasenia in Russia and Den- 
mark forms the subject of a paper by Gunnar Andersson in the 
botanical section of the appendix to volume xxii of the Zransactions 
of the Royal Swedish Academy of Stockholm, issued in 1897. Two 
plates illustrate the structure of recent and fossil specimens, the 
former from Japan and the United States. 
Dr. Ernst Huth, whose death in August last cut short a promising 
botanical career, had prepared a paper on the Ranunculacez of 
Japan, with especial reference to the species collected by Father 
Faurie between 1885 and 1896, which is published in the Bulletin 
of the Boissier Herbarium for December, 1897. 
The Bavarian Botanical Society, which has its home in Munich, is 
publishing in its Berichte a preliminary flora of Bavaria, in which full 
ordinal descriptions, keys to genera, full generic descriptions, keys to 
species in the larger genera, and detailed specific descriptions are 
` given. In many cases the geographical range of the several species 
of a genus is indicated on reduced maps of the country, which, for 
the more ready contrast of related species, are printed in pairs in 
the text. Thus far, the flora reaches Dentaria, in the Crucifere. 
A somewhat similarly treated flora of the neighborhood of Nurem- 
berg and Erlangen, by A. F. Schwarz, which is being issued in parts 
by the Natural History Society of Nuremberg, reaches the Rutacez, 
in the tenth volume of the Abhandlungen of the Society. 
Acalypha virginica, a common North American plant which has 
become established in Italy, forms the subject of a note by Traverso 
in Malpighia for 1897. It appears that in the vicinity of Pavia, in 
addition to this species, Azol/a caroliniana, Elodea canadensis, Com- 
melina virginica, Oxybaphus nyctagineus, and Solidago serotina, all 
pertaining to our flora, have rather recently become established. 
Euphrasia canadensis, a supposed new species from the vicinity of 
Quebec, is described and figured by Frederick Townsend in the 
Journal of Botany for January 
Frederick N. Williams publishes in the January number of the 
Journal of Botany a short article on primary characters in Ceras- 
tium, and characterizes in accordance with his views Dichodon, — 
Strephodon, and Orthodon as subgenera,
