SUPPLEMENT TO THE MONOGRAPH OF THE NORTH AMERICAN 
UMBELLIFERAE, * 
By Jonn M. Courter and J, N. Ross. 
INTRODUCTION. 
In 1888 we published the Revision of this family, and in 1900 our 
Monograph appeared. Since the latter publication enough material 
has accumulated to justify a short Supplement. Itis to be remem- 
bered that the area covered is North America north of Mexico. This 
Supplement includes a record of all new species described since 1900 . 
and of all transfers made by others which have seemed to us justifi- 
able; descriptions of two new genera and six new species; the entry 
of a well-established introduced species; certain transfers which have 
seemed to us necessary; and a bibliography for the period since 1900. 
We have not included all changes that have been proposed, either 
because our material does not warrant an opinion, or because they do 
not seem to us to be justified. It is to be understood, therefore, that 
we have made no changes in the names used in the Monograph except 
as they are indicated in this Supplement. 
BIBLIOGRAPHY.

seem to us to be justified :

«The family name Apiaceae has been in general use in the Contributions, but we 
have retained the name Umbelliferae on account of the relation of this paper to the 
two preceding ones. Under the Vienna rules, it is made an exception to the rule for 
the formation of family names.
