Herb. Bog. [BO]: 1243 New Guinea nos (dried and in alcohol) incl. 231 nos from the NW. part; dupl. in Herb. Leiden [L], Utrecht [U], Kew [K], Berl. [B], etc.8

Important collections were lost, when a vessel capsized during the Dutch-German expedition. At first he was assisted by the Indonesian Sadeli, later by mantri Ajoeb (see there) of the Botanic Gardens at Buitenzorg. From a list of numbers of his collection, present at the Buitenzorg Herbarium, it is evident that he started collecting in March 1910.

Together with Ajoeb he collected many living plants for Hort. Bog.;9 in the cited list is an orchid from Boeroe, which may have been collected on the home voyage.
