o HISTORY OF THE INVESTIGATION OF THE FLORA OF SURINAM. 



who about 1855 was a physician at Paramaribo. This collection is also found 

 in the Utrecht herbarium. 



Of the collections mentioned only those of Weigelt and of Hostmann 

 and Kappler have become more widely known. The collection which Host- 

 mann had brought together before, making the acquaintance of Kappler, came 

 for the greater part into the hands of Hooker and was spread from Kew. 

 The specimens are all numbered, but about the place where they were found 

 nothing is mentioned. They have not been published separately, but have 

 been dealt with especially by Bentham in his numerous contributions to 

 various numbers of the London Journal of Botany. Kew possesses the most 

 complete collection of Hostmann's plants ; these are also found in the her- 

 barium of the British Museum, in the Delessert herbarium and incomplete 

 in the Utrecht herbarium. 



Later Hostmann put himself into relation with Hohenacker. At any rate 

 we find in Flora of 1843 on page 655 the announcement of the first 200— 

 350 species, which are offered for sale by Hohenacker undetermined, with 

 the communication that numerous botanists are already occupied in naming 

 them and that the labels with the names will soon follow. In the same volume 

 of Flora we find the first publication on this material by Steudel, containing 

 the enumeration and partly the description of 108 species. 



Meanwhile Miquel had already in 1840 published in his Fragmenta 

 phytographica, vol. II, part of the Melastomaceae, collected in Surinam by 

 Focke. I do not know how Miquel became acquainted with Focke. 



The fairly well preserved collection was commenced in 1835 ; part of 

 it came into the hands of Splitgerber, the remainder was sent in batches 

 to Miquel who gave it a place in his private herbarium which was later 

 bought by the Utrecht university, where it is at present. Only some 

 duplicates were distributed by Miquel, e. g. to Grisebach and Bentham, so 

 that duplicates are found at Gottingen and Kew. Another part of the 

 duplicates is in the State herbarium at Leyden. 



Meanwhile Kappler continued sending fresh collections to Europe. In 

 Flora of 1845 and 1846 we find Hohenacker's announcements concerning 

 these plants. Several botanists occupied themselves with the determination 

 of this material. So Kunze determined the ferns, Hochstetter the Gramina 

 and Cyperaceae, Seubert another part of the Monocotyledons; Lindley the 

 Orchidaceae, Schultz bip. the Compositae, Steudel the Melastomaceae, 

 Bernhardi part of the Leguminosae and Miquel the rest. Steudel's publi- 

 cation is found in Flora of 1844; Miquel's chiefly in Linnaea XVIII (1844) 

 and XIX (1847). In the meantime Miquel went on working at Focke's 

 material. In the Tijdschrift voor Natuurlijke Geschiedenis en Physiologie X 

 (1843) a part is first published, the chief part however in Linnaea XVIII 

 (1844), partly mixed with the material of Hostmann and Kappler. The 

 best known publication by Miquel on this material is his work: Stirpes 

 Surinamenses Selectae, published separately in 1850 as the 7 th volume of 

 the Transactions of the Dutch Scientific Society at Haarlem.
