les Alpes frangaises. (C. R. de l’Ass. fr. pour l’Avanc. des Sc.; 
Congres de Reims, 1907. p. 418—425, 3 cartes. Paris, 1908.) 
L’auteur a etudie et figure sur trois cartes la distribution geo¬ 
graphique de 19 especes de Primidacees dans les Alpes frangai- 
ses: 1° les Primula (8), 2° les Aretia (4) et le Gregoria Vitaliana 
Duby, 3° les Androsace (6). De ce travail se degagent entre autres 
faits l’abondance de Primidacees dans la region S. E. des Alpes, 
leur rarete dans la zone du Mont-Blanc; on voit bien l’aire du 
Primula Auricula L. se superposer aux Prealpes calcaires (Char¬ 
treuse et Vercors), celle du P. graveolens Heg. aux Alpes 
austro-occidentales et aux Alpes maritimes. J. Offner.

N°. IV. Wicken Fen. (New Phytologist. VII. N°. 283. 7 figs. and 
1 plate. 1908.) 
Wicken Fen is the largest existing area of the once extensive 
“Fenland’ 4 of England which occupied about 1300 sq. miles 
round the Wash. The greater part is now under cultivation or 
much altered by drainage, and even Wicken is drained to some 
extent and exhibits all the features of a drying-up marsh. The Vege¬ 
tation of W i c k e n is typical marsh (Hochmoor) with grass-like 
monocotyledons — Gramineae, Cyperaceae and Juncaeeae — mixed 
with some dicotyledons; bog plants such as Sphagnum , Eriophorum, 
and Ericaceae are absent. A narrow reed-swamp with Phragmites 
communis as the dominant plant fringes the artificial drains; where 
land-formation has progressed, the general Vegetation is mixed, 
Cladium Mariscus, Molinia coerulea, Phragmites, being some of the 
dominant plants. The author has given special attention to the 
relation of species to soil-moisture, and in a list, illustrated by a 
useful diagram, he arranges the commoner marsh plants “with 
respect to degree of soil moisture which would seem to be the opti-
