tion of 1894, collected by Dr. H. E. Wetherel has been published in 
Bulletin No. 5 of the Geographical Club of Philadelphia. It contains 
108 species as follows: flowering plants, 77; fernworts, 5; mosses and 
liverwort, 6; algæ, 2; fungi, 2; lichens, 16. Twenty-two families of 
flowering plants were represented as follows: Graminew, 12; Caryo- 
phyllacee,10; Crucifere, 8; Cyperacee, 6; Rosacea, Rube Praprisac, 
Ericacee, Scrophulariacee, 5 each ; Oonpas, 4; Ranunculacee, Ona- 
gracee, Polygonacee, Salicacee, 2 each ; Paperari Portulacacee, Dia- 
pensiacee, Plumbaginaceæ, Boraginacee, Betulacee, Empetacee, Lil- 
iacee, Juncacee, 1 each.— Recent Contributions from the Herbarium 
of Columbia College contain papers by Mrs. Elizabeth G. Britton (72) 
on the Systematic Position of Physcomitrella patens, and a couple of 
hybrid mosses; by John K. Small (73) some new hybrid oaks from the 
Southern States (Quercus phellos X digitata, Q. georgiana X nigra, Q, 
catesbæi X cinerea) ; by George V. Nash (74) notes on some Florida 
plants (including a number of new species); by N. L. Britton and 
Anna M. Vail (75) an Enumeration of plants collected by M. E. Pen- 
ard in Colorado during the summer of 1892; by Albert Schneider (76) 
the biological status of lichens; by N. L. Britton (77) new or note- 
worthy North American Phanerogams (including several new 
species, one being Ranunculus allegheniensis, from the Mountains of 
Virginia and North Carolina)—From the Proceedings of the 
American Microscopical Society for 1894, we have two valuable 
papers, viz.: The Aeration of Organs and Tissues in Mikania and 
other Phanerogams, by W. W. Rowlee, and the Structure of the 
fruit in the order Ranunculacee, by K. M. Wiegand. Both are fully 
illustrated by good plates—Professor V. M. Spalding’s paper on the 
Traumatropic Curvature of roots (Annuals of Botany, Dec., 1894) 
familiarizes us with a new word, and gives a somewhat different explana- 
tion to root motions than that made by Mr. Darwin.—In the contribu- 
tions from the Subtropical Laboratory of the Division of Vegetable 
Pathology of the U. S. Department of Agriculture (pub. in Report of 
Mo. Bob. Garden, Vol. 6) Herbert J. Webber gives the results of his 
studies on the dissemination and leaf reflexion of Yucca aloifolia and 
other species. Some interesting adaptations are shown by the author 
The leaf reflexion is shown to be a protective device against climbing 
animals which would be tempted by the succulent fruits.—“ American 
Nomenclature” is the title of a long article by the editor of the Journal 
of Botany (London) in the July issue. The most remarkable part of 
the paper is that quoted anonymously from an American letter, in 
which occur some astonishing statements, e. g. “ Weare now in a very
