RECENT BOTANICAL LITERATURE. 49 
variety of Franseria camphorata, Greene, described new 
from Lower Californian specimens, will be the plant, which is 
common on Cedros Island, where I collected it in 1885. Men- 
tion is made of it, as a form, in the note appended to my 
description of the type. 
The interesting and instructive remarks on Solidago erecta, 
Galvesia juncea and many more species, are of that class 
which impart to all such papers of Professor Gray a value 
which none but critical students can fully appreciate. En- 
riched as they are by the ripest erudition of the most eminent 
of New World botanists, they will not depreciate with the 
appearing of that wished for volume of Synoptical Flora to 
which the author calls them precursory; for the learning 
that is stored in them can not re-appear in full upon the 
pages of the book itself. It is this characteristic of the whole 
long succession of these Contributions by Professor Gray, 
which will render the volumes of Proceedings of the Ameri- 
can Academy a treasury of North American botany through 
all the years to come.
