HIGHLIGHTS OF BOTANICAL EXPLORATION IN THE NEW WORLD 23 1 



In 1948 Frere Wilson-Brown obtained more than 600 collections in the 

 Kanuku Mountains. The original set is at New York. 



Nicholas Guppy, from September through November, 1952, visited the 

 Akarai Mountains along the British Guiana-Brazilian frontier. He collected 

 679 numbers of vascular plants which are being studied at New York. 



In a series of expeditions, Bassett Maguire, with D. B. Fanshawe in 1944 

 and 1951-1952, with R. S. Cowan in 1954-1955, and with W. M. C. Bagshaw 

 and C. K. Maguire in 1955, collected variously in British Guiana. The first 

 sets of more than 2250 numbers are at New York. 



SuRiNAME. Among the many early collectors in Suriname were F. Allamand 

 (1756-1771), specimens at the Linnean Herbarium; F. W. Hostmann and 

 A. Kappler, separately and together during the period 1824-1840, who made 

 extensive collections which are widely distributed in herbaria; the collections 

 of H. C. Focke (1835-1850) are chiefly at Utrecht; F. L. Splitberger (1837- 

 1838), whose original collection is at Leiden; C. Weigelt (1827-1828), whose 

 collections are widely distributed; and H. R. Wullschlaegel (1849-1855), 

 whose original collections are at Brussels. 



The most important body of material recently collected in Suriname has 

 come from officers of the Forest Bureau, who have amassed nearly 10,000 

 specimens, the original set of which is at Utrecht. Individual collectors who 

 have contributed most significantly are A. A. Pulle (1903-1904, 1920), whose 

 original sets are at Utrecht. His expedition in 1903-1904 was the impetus 

 for the further preoccupation during his life with the flora of Suriname. He 

 wrote the "Enumeration of the Vascular Plants Known from Surinam," 1906, 

 and organized and edited the earlier parts of the new Flora of Suriname, 

 initiated in 1932. J. Lanjouw, who has visited Suriname frequently since 

 1933, is presently editor-in-chief of the continuing Flora, and himself has 

 in the field collected large series of plants, the original sets of which are at 

 Utrecht. Gerold Stahel, who was director of the Agricultural Experiment 

 Station in Paramaribo from 1914 to 1939, and his associate, D. C. Geijskes, 

 made various expeditions into the hinterland. Their collections are largely 

 at Utrecht. More recently, J. S. Lindeman, F. P. Jonker, and A. M. E, Jonker 

 have studied chiefly the Araceae and other monocotyledons in coastal Suri- 

 name. Their collections are at Utrecht. 



In April and later from June to October, 1944, Bassett Maguire collected 

 with Gerold Stahel in the coastal regions, and independently in the interior 

 on the Saramacca River and Tafelberg. The first set of more than 1600 num- 

 bers is at New York. 



In 1954-1955, R. S. Cowan and J. C. Lindeman, and Bassett Maguire col- 

 lected nearly 400 numbers on Nassau Mountain and in the vicinity of 

 Moengo. The materials are at New York and Utrecht. 



French Guiana. Subsequent to the activities of Aublet were the collections 

 of L. C. M. Richard (1781-1785), J. B. Leprieur (1830-1836), A. Poiteau
