HIGHLIGHTS OF BOTANICAL EXPLORATION IN THE NEW WORLD 235 



bey's original set is at Paris. Their Flora Peruviana et Chilensis in three vol- 

 umes, 1798-1802, is the beginning point of the important literature dealing 

 with plants of Peru. 



Over the next hundred years, numerous botanists visited and collected in 

 Peru, among the notable being Bonpland (with von Humboldt) in 1802. E. F. 

 Poeppig arrived in Peru in May of 1829, where he collected until he crossed 

 the BraziHan frontier in August, 1831, after which he departed from Para in 

 October, 1832. His herbarium representing approximately 2000 species is 

 at Vienna; duplicates are widespread. Andrew Mathews from 1833 to 1841 

 collected in various parts of Peru, assembling some 10,000 numbers; the more 

 complete set is at Kew. Antonio Raimondi traveled through the entire coun- 

 try, 1851-1859, collecting a great mass of 13,000 numbers which was studied 

 at Berlin. Raimondi was the first of the Peruvian botanists to make a con- 

 tribution of consequence to his country. In acknowledgment of his great 

 services, Weberbauer dedicated his own El niundo vegetal de los Andes Peru- 

 anos to Raimondi. Richard Spruce in the years 1855-1857, while engaged 

 on his Cinchona program, collected numerously in Peru ; Ernst Ule from Au- 

 gust, 1902, to April, 1903, collected in eastern Peru near Yurimaguas, and 

 especially in the vicinity of Tarapoto. 



The very important work of Weberbauer began in the autumn of 1901 and 

 continued until the spring of 1940. During this period of nearly forty years, 

 Weberbauer was absent on trips to Europe on two occasions, from September, 

 1905, to September, 1908, and from December, 1929, to June, 1930. To sup- 

 port his extensive ecological and phytogeographic studies, Weberbauer col- 

 lected some 8100 numbers which were deposited chiefly at Berlin; duplicate 

 collections are at Breslau, Geneva, Chicago, Gray Herbarium, Washington, 

 and the School of Agriculture in Lima. 



From 1922 over a period of eleven years, Fortunato L. Herrera collected 

 some 3800 numbers, which were deposited in part in Berlin, Washington, New 

 York, Chicago, and Gray Herbarium. J. Francis Macbride carried out two 

 expeditions, the first in 1922, in which he collected approximately 18,000 speci- 

 mens and upon which he laid the basis of his great work The Flora of Peru. 

 Beginning in 1936, many parts have been issued; the work continues in pre- 

 paration. Gunther Tessman, ethnologist, in 1926 amassed a collection of 6000 

 numbers, the first set of which was deposited at Berlin. Francis W. Pennell 

 in 1925 collected in Peru and Chile, obtaining 2617 numbers, of which the first 

 set is at New York. In 1927 Carlos Schunke collected for the Field Museum 

 in Chicago. In 1929 E. P. Killip and A. C. Smith collected in a considerable 

 part of eastern Peru. Llewelyn Williams in 1929-1930, chiefly in Amazonian 

 Peru, collected a large series of 8252 numbers and 2500 wood specimens, the 

 first set of which is at Chicago. G. Klug, a nationalized Peruvian, collected 

 chiefly in the year 1929 in northeast Peru, obtaining 4403 collection numbers, 

 the original set of which is at New York. In 1931 and later in 1935-1952,
