REPORT ON MEXICAN UMBELLIFER, MOSTLY FROM THE STATE 
OF OAXACA, RECENTLY COLLECTED BY C. G. PRINGLE AND 
E. W. NELSON, 
By Joun M. Courter and J, N. ROSE. 
HISTORY OF COLLECTIONS. 
The collections of Umbellifere herein reported are the largest and 
most important ever brought from Mexico. We had looked forward 
with considerable interest to the results that should be obtained by 
Mr. Pringle and Mr. Nelson in the State of Oaxaca, and had urged 
the importance of collecting the species previously reported from this 
State. A number of rare species are known only from this region, and 
it is practically unrepresented in our herbaria. The National Herba- 
rium contained but a single umbellifer from Oaxaca. In order that 
these collectors might obtain fresh specimens of the old species, as 
complete data as possible as to descriptions and stations were furnished. 
The care and diligence that they have shown are clearly brought out by 
the results here published. Not only have they collected nearly all the 
species previously obtained, but they have enabled us to establish 4 
new genera and 27 new species. The number of Umbelliferi which 
had previously been collected in the State of Oaxaca is very small. 
Hemsley, who has brought together the only compact list, enumerates 
in the Biologia Centrali-Americana 15 species, and 5 of these are deter- 
mined only generically. Below we give a list of these species, as named 
by Mr. Hemsley, with the locality and collector.
