BOTANICAL TRIP HITCHCOCK 351 



Mille is continuing the work of Sodiro in the study of the Ecua- 

 dorian flora. 



Our loiowledge of tlie flora of Peru has been greatly enlarged by 

 the work of Dr. A. Weberbauer, a German botanist long resident 

 in Peru and now living in Lima. Doctor Weberbauer is known not 

 only by the large number of plants he has collected and sent to 

 European herbaria but also by his great work on the distribution 

 of plants in the Peruvian Andes (Die Pflanzenwelt der peruanischen 

 Anden) and his phytogeographical map of the region (Mapa Fito- 

 geographico de los Andes Peruanos). 



Dr. Otto Buchtien's work in Bolivia has been mentioned in a 

 preceding paragraph. Dr. H. H. Rusby, of Columbia University, 

 New York, has collected in the montafia of northern Bolivia, and 

 Mr. Macbride and his assistants are now engaged in botanical ex- 

 ploration in Peru for the Field Museum of Chicago. There have 

 been other botanical explorers in the three countries under consider- 

 ation, but altogether the flora is less known than most other parts 

 of South America.
