Collectors of our time who have contributed largely to the flora of Panama 

 are those resulting from a series of explorations sent out by The New York 

 Botanical Garden, J. F. Cowell in 1905, M. A. Howe in 1909-1910, and the 

 important collections of R. S. Williams made in 1908; J. Francis Macbride 

 and J. N. Rose in 1918; E. P. Killip in 1917-1918 and 1922; C. V. Piper in 

 1923; and W. R. Maxon in 1911 and 1923. Henri Pittier, after his work in 

 Costa Rica, Mexico, and Colombia, went to the Canal Zone in 1910, and in 

 1914-1915 amassed there a collection of 4175 numbers. During 1935-1943 

 Steyermark actively collected in Panama and Guatemala. 



From the enormous work of these indefatigable workers, there has resulted 

 Standley's flora of the Panama Canal Zone, flora of Costa Rica, and the flora 

 of Guatemala by Standley and Steyermark and collaborators. 



Standley's "Flora of Costa Rica" {Field Mus. Nat. Hist. Vol. 18, Pts. 1-4, 

 1937-1938) is one of the best-documented floras of any part of Central 

 America. Standley himself made two expeditions to Costa Rica, 1923-1924 

 and 1925-1926, during which he collected some 15,000 numbers of vascular 

 plants. In addition to his own and historical materials, Standley had available 

 the rich collections of the resident botanists, Pittier, Tonduz, Biolley, 

 Werckle, Brenes, and the Brade brothers, whose carefully planned and exe- 

 cuted expeditions netted some 18,000 numbers. Henri Pittier had lived in 

 Costa Rica 1887-1903, and during this time had separately made about 5000 

 collections. Alberto M. Brenes, according to Standley, assembled the largest 

 set of Costa Rican plants, some 20,000 numbers, collected by any one indi- 

 vidual. Sets of his specimens are at Chicago, New York, Harvard, Wash- 

 ington, and probably elsewhere. His personal herbarium is deposited at 

 New York. 



The Flora of Guatemala by P. C. Standley and Julian A. Steyermark, 

 issued in parts, with the collaboration of other authors, not yet completed, 

 has been issued as Fieldiana, Vols. 24-25, 1949-1955. Volume 25, 1949, 

 comprises the Mosses of Guatemala by Edwin B. Bartram; Vol. 24, Part 2, 

 1955, the Grasses of Guatemala by Jason R. Swallen, with the Bamboos by 

 F. A. McClure; and Vol. 26, Part 1, 1952, and Part 2, 1953, the Orchids of 

 Guatemala by Oakes Ames and D. V. Correll. 



At the Escuela Agricola Panamericana, near Tegucigalpa, Honduras, 

 founded by Dr. W^ilson Popenoe with the support of the United Fruit Com- 

 pany, over the past decade an effective herbarium of Central American plants 

 (and supporting library) has been developed chiefly from the field industry 

 of Louis O. Williams, Paul H. Allen, and their associates, Sr. Molina and 

 others. Having established a well-coordinated organization for the collation 

 of taxonomic, economic, and agricultural information, Ceiba, A Scientific 

 Journal was begun by Drs. Popenoe and Williams and their colleagues, in 

 1950 (Vol. 1, No. 1, June 23; and it had reached Vol. 5, No. 4, by January, 

 1957).
