In 1949 a trip was made to Kenya Colony, British East Africa, with the aim of collecting Phanerogamic plants and Ferns. The intention was to collect 12 sets of each number which I managed to do for about 70 %. Except for the first set which will be incorporated in the Rijksherbarium, the plants will be sold to those institutes in Europe, S. Africa and America which had subscribed in advance. It is expected, however, that a few more sets in excess of the 12 aforementioned will be available. It should be noted that these will prove rather incomplete, numbering less than 30 % of the total amount.
