THE SECOND FASCICLE of L&VEILLE’s? monograph of Oenothera has appeared, 
the first fascicle having been noticed in this journal for April 1903 (p. 296). 
Naturally it is of great interest to American taxonomists, and contains a profusion 
of illustrations. The genera Eulobus and Gayophytum have been merged under 
Oenothera, and O. bistorta Nutt. has been replaced in great part by O. chieranthi- 
jolia Hornem.—J. M. C. 
THE FOREST WEALTH OF OREGON is the title of a small pamphlet prepared

forest trees and larger shrubs. Of these thirty-eight are gymnosperms.—C. R. B. 
In conTINUING his revision of Eucalyptus, MAIDEN’? presents E. stellulata, 
E. coriacea, and E. coccifera, under each species giving the description, synonyms, 
range, and affinity.—J. M. C.

NOTES FOR STUDENTS. 
HESSELMAN™ has published a paper on Swedish meadows, which should 
be carefully read by all who are engaged in ecological research, since no recent 
paper has gone more fundamentally or successfully into the real problems of 
ecology. The studies have been carried on for nearly a decade, and in a rather 
imited area in the neighborhood of Stockholm, and with especial detail on the 
little island of Skabbholmen. The “Laubwiesen” are meadows in which there 
are scattered deciduous trees, the general aspect being park-like. They might 
perhaps be regarded as edaphic savannas. ‘These formations are rich in herbs 
and ses, and are essentially without low shrubs. At an earlier time the 
“‘Laubwiesen” covered extensive areas, but they are now restricted to what may 
be called new terranes, especially near the coast and about inland lakes. They 
seem to be particularly favored by maritime climates and calcareous soils. lor- 
istically the vegetation is closely related to that of oak or beech woods on calcareous 
soil rich in humus. The dominant trees are ash, oak, linden, elm, and beech,
