HIGHLIGHTS OF BOTANICAL EXPLORATION IN THE NEW WORLD 233 



His most important and contributive program has been as follows: his first 

 expedition of 1932, sponsored by the University and Botanical Garden of 

 Madrid, was conducted in the region of the Rio Magdalena and Valle del 

 Cauca, yielding 1 500 numbers which are chiefly at Madrid ; the second expedi- 

 tion of 1938, sponsored by the University and Botanical Garden of Madrid, to 

 the regions of Cundinamarca, Boyaca, Soata-Cocuy, and the llanos of the 

 Meta, resulted in the collection of 3500 numbers which are chiefly at Madrid; 

 during the third period, 1939-1942, as Professor of Botany at the Universidad 

 Nacional, Bogota, he made excursions chiefly to the llanos and rain forests 

 of Meta, Vichada, Vaupes and Amazonas, the East Cordillera, the Central 

 Cordillera, and the West Cordillera, and parts of the lower Magdalena Valley 

 and Cauca Valley, from which 8861 numbers were obtained and are chiefly at 

 Bogota; during the fourth period, 1942-1947, as Professor of the Agronomic 

 Faculty of El Valle and Director of the Comision Botanica del Valle, he made 

 expeditions to the West Cordillera on both slopes and their highest peaks, the 

 rain forest of the Pacific Coast, the mangrove areas of the west coastal range, 

 the Central Cordillera, and the plains of the Cauca Valley and Popayan, 

 resulting in 11,000 collections which are chiefly at Call. Collaborators in 

 the field with Dr. Cuatrecasas have been H. Garcia-Barriga, R. Jarmillo, 

 Perez Arbelaez, R. E. Schultes, E. Smith, R. Metcalf, and E. P. Killip (with 

 his own enumeration). Large sets of Cuatrecasas' plants are at Chicago and 

 Washington. 



Cuatrecasas' numerous writings have clearly made his the outstanding 

 present-day contributions to the literature of the botany of Colombia. 



E. P. Killip, in association with a number of associates, has made three 

 major expeditions and several shorter visits in Colombia. On the first expedi- 

 tion in 1922, in the company of F. W. Pennell and T. E. Hazen, he collected 

 extensively about Buenaventura Bay and in the luxuriant forests at the base 

 of the western cordillera and the paramo of Sta. Isabel. On the second, 1926- 

 1927, E. P. Killip and A. C. Smith in five months carried on exploration in 

 the region of Cartagena and Calamar on the Magdalena River, vicinity of 

 Turbaco, Arjona, and Puerto Wilches. With Bucaramanga as headquarters, 

 they collected in this region and elsewhere on the western slopes of the Eastern 

 Cordillera near Piedecuesta, Mesa de los Santos, Las Vegas, and northward 

 in the vicinities of Surata, San Antonio, La Baja, and Charta and visited the 

 paramos at Santurban, Vetas, Rico, Los Colorados; Mutistua, paramo de 

 Santurban, Pamplona, Toledo, and Norte de Santander; Cucuta and Mara- 

 caibo. A total of some 7000 numbers yielding approximately 25,000 specimens 

 were obtained by these effective field men. Killip on his third Colombian 

 expedition in 1939 visited Gorgona Island; explored the region from Bogota 

 to Villavicencio (with A. H. G. Alston) in the western cordillera and visited 

 the interior of Choco. Much of this period was spent with H. Garcia-Barriga. 

 Approximately 2700 numbers yielding 11,000 specimens were obtained. The
