This may be D.H.R. van Gelder (1809, Leiden, Holland), preparer, put at the disposal of P.W. Korthals (see there) in 1830, in company with whom he visited the north coast of Java and the Padang Highlands.2

According to Sirks3 he left the committee before Febr. 1836; according to Backer,2 however, he resigned in 1838, and was later employed at the, in 1844 discontinued, Natural History Museum at Weltevreden. In the register of the Dutch Government it is recorded that he was granted permanent leave on April 4, 1838, in order to settle as a manager on the Tariek and Gabang Lands; he finally left Java in 1857. As it is evident that he was still in the employ of the committee when Korthals, visited Borneo in 1836, he may have accompanied the latter.

Ficus gelderi Miq. was named after him.



Is cited by Blume1 as the collector of Gnetum leptostachyum Blume in Borneo, the type specimen of which is preserved in Herb. Leiden [L].
