instability of which is once more demonstrated in a severely critical 
article by Mr. M. L. Fernald, published in the Botanical Gazette 
for last ie to which, if space permit, we propose to return. 
A few points of detail seem to us open to criticism. What 
are absurdly called ‘‘ English names” are given—not for ‘each 
Species,”’ as stated in the preface, but for most of them; sometimes 
these are Latin, tout court, as Brachyelytrum, but in m most instances 
they are translations of adaptations —what claims have ‘ Filiform 
tapi or ‘‘ American Korycarpus”’ to be called “ English 
e are two indexes, one rs Latin and one of 
n relish ” names, the Seat being lim to genera; these 
of the name in full in connection with each s speci e regre ret 
that the author should sanction the abbreviation of his name ina 
manner which may cause confusion: “ Britt. & Holl.”-—the authori- 
ties cited for a species of Lechea—stands for * Britten and Holland ” 
cee with ‘ Britton aes Hollick.”” But these are small matters : 
e book is a welcome addition to botanical literature, and must 
ai rank as the senile’ stinvitind of North American botany.
