have found almost side by side in various places, will appreciate a 
critical article on the annual species of Anagallis of Europe, which 
M. Clos publishes in No. 7 of the Bulletin de la Société Botanigue de 
france for 1897. 
A note by M. Franchet, in No. 7 of the Bulletin de la Société Botan- 
iqgue de France for 1897, shows that, though certain reduced forms 
of B. lunaria have been mistaken for it, Botrychium simplex really 
occurs in France. 
Another application of anatomical characters to the delimitation 
of species has been made by Gillot and Carmentier, who show, in 
No. 7 of the Bulletin de la Société Botanique de France for 1897 that 
Rumex palustris is a hybrid of R. maritimus and R. conglomeratus, 
In a paper on “ The Spruces of the Adirondacks,” read before the 
Albany Institute in November, 1897, Professor Peck states that, 
though until recently only two species of Picea were credited to the 
Adirondack region, there is now good evidence of the presence there 
of four species: P. canadensis, the white spruce, P. mariana, the 
black spruce, P. rubra, the red spruce, with a dwarf variety, P. rubra 
pusilla, and what is held to be a new species, the swamp spruce, 
P. brevifolia, with a dwarf variety, P. brevifolia semiprostrata. 
That the active use of insecticides and fungicides, promoted by

tural Experiment Stations, is being watched with interest in England, 
is shown by the publication in the December number of the Journal — 
of the Royal Horticultural Society of a rather extended paper by S. C. 
Lamb on “The Treatment of Insects and Fungi in the United 
States.” 
To cultivators of hothouse plants an article on the genus Nepen- 
thes, by H. J. Veitch, published in the December number of the 
Journal of the Royal Horticultural Society, cannot fail to prove of 
interest. In it are given a historical account of the introduction 
of these Old World pitcher plants into cultivation, and a number of 
ecological and cultural observations. Several species are figured, 
some of them in the early stages of development. 
That the botanists of far-away New Zealand are active is shown 
by the Zransactions and Proceedings of the New Zealand Institute for 
1896, recently received, which contains no less than twenty-one 
botanical articles, among them several of considerable ecological
