The more important “list” is introduced by an account of the litera 
ture of the group, following which the genera and species are presented _ 
alphabetically. The literature, synonymy, and native habitat are 
fully cited, and as most of our North American species are cultivated 
in the British Isles the list becomes quite a complete bibliographical — 
index of the group for American botanists. In regard to nomen ~ 
_clature the author has followed the principles of Bentham and © 
Hooker, so that the names adopted are not to be considered as repre- 
senting the most recent agreement concerning nomenclature. 
Diona has always been a fascinating study, and although its history 
seemed to be fully written, Mr. Bashford Dean has given us a most 
interesting account of its actions in its native haunts, and has supplied © 
us with valuable information. It has always been a question whether | | 
we were getting at all the facts from the study of greenhouse speck : 
mens. Mr. Dean summarizes some of his results as follows: (x) Spe 
cialization for the capture of ground insects. (2) Marked differences — 
in irritability in individual leaves; the usual inability of the plant to 
the trap in parts other than the filaments. It would seem that the 4 
name “ fly-trap ” is singularly inappropriate. { 
THE FLORA of Lower California promises to be as prolific of new 
things as that of Mexico. Mr. Brandegee has already published @ — 
voluminous report of this region, and has now issued? a small pam 
phlet containing “additions,” which were the result of a trip to the — 
Cape region in March and April of 1892. In addition to interest 
are Leguminose (Dalea, Acacia, and Albizzia). The occurrence of * | 
Albizzia in our N. American flora is unexpected, as the genus bee 
thought to be confined to warm regions of the orient. 4 
THE FLORA oF Mexico, Owing to the persistent activity of that wom 
derful collector, Mr. C. G. Pringle, is being rapidly brought to out 
knowledge. It is also a very great advantage that so much of this rich
