collections:

Herb. Utrecht [U]: remaining part of the collection, the numbering of which, as far as known, runs to 845. The greater part was lost as the shipment of the cases containing the collecting tins (Schweinfurth method) was retarded at Priok on account of the war; on arrival in Holland several tins were corroded and the contents were worthless.

Some of the plants were preliminarily identified by van Steenis in 1923.
