and P. insignis, Douglas, in London Arboretum, 1844, are, ac- 
cording to the author, the synonymy of the Monterey pine. The 
editor of Garden and Forest admits the possibility of Loiseleur’s 
plant being the species now commonly known as Pinus insignis, 
but excludes the name on the basis that the description of the 
seeds is faulty and adopts the next oldest specific name, P. ¢uder- 
culata, Don. :

A collection of popular essays on the trees, both native and 
cultivated, of Salem and its immediate neighborhood. These 
articles written for the Salem Gazette and now brought together 
in book form, show a good deal of originality in collecting and 
putting together a mass of historical facts of local interest. 
Patterson's Numbered Check-List of North American Plants, 
North of Mexico. H.N. Patterson. (Large 8vo. pp. 158, 
Oquawka, Jan., 1892). 
This most useful catalogue of North American Plants was 
advertised in our last number, but it is desirable to place its pub- 
lication on more permanent record. The number of species and 
Varieties of Flowering Plants, Ferns and Fern-allies indicated by 
this list is 12,794, the number of species being 10,706. It has 
evidently been prepared with much care and is beautifully 
Printed. It is by no means complete, however, as will be very 
apparent from the statement that there are at least twenty-five 
additional species and varieties of Ranunculacee in addition to 
the two hundred and thirty-four listed, a considerable number of 
them published, it should be said, after Mr. Patterson's manuscript 
Went to press. The value of the work is enhanced by a capital 
index, N.dcB:
