of this tree the author considers it as a variety of Quercus imbri- 
caria. Without contributing any new facts to the argument, the 
opinion is expressed “ that further investigation will confirm the 
conclusion here reached.”” Unfortunately, the geographical range 
of this species is such as almost to preclude the possibility of any 
connection between it and heterophylla, at least the distribution 
of the two trees is such that almost any other likely hypothesis 
ought to be considered before adopting this one which appeals 
so strongly to the improbable. The author mentions a tree found 
by him in Salem Co., New Jersey, which he refers to an entire 
leaved form of heterophylla (imbricaria ?). The specimens of this 
tree in the Herbarium of Columbia College are manifestly not 
imbricaria but Rudkint, as first determined by Dr. N. L. Britton 
when submitted to him. So far as can be ascertained no zmért- 
caria occurs north of Delaware, but heterophylla is found as far 
north as Staten Island, New York. If it is to be regarded as a 
variety its invariable connection with Phellos is too significant 
to be ignored, but all facts and observations seem to point irre- 
sistibly to the conclusion that we must consider heterophylla as 
a hybrid, with Pfed/os as one of its parents. : A. H. 
Botanical Names of the U. S. Pharmacopeia. (Bull. Pharm. 
Reprint, pp. 20). : 
This is an important paper presented at the recent meeting 
of the American Pharmaceutical Congress. Dr. Rusby has given 
very close study to the names associated with drug-plants in the 
last edition of the “ Pharmacopceia,” and finds that a number of 
them will have to be changed in the new edition now in prepara- 
tion, in order to make them intelligible to botanists and pharma- 
cists as well. He givesa list of all the drugs, arranged alphabet- 
ically, with the proper botanical names and their dates, so far as 
he has had opportunity to ascertain them, together with their 
synonymy, and proposes to continue his investigations until they 
are all accurately determined—a task of no small magnitude, but 
for which he will have the cordial thanks of all interested.
