In continuation of the revision of the genus Cadia (van der Maesen 1970) some cytological work was done on Cadia purpurea (Picc.) Ait. The chromosome number had never been reported. When seeds became available, a number of slides was prepared in order to count the chromosomes. The seed material used was collected by J. J. F. E. De Wilde in the vicinity of the bushes, from which nrs. 4103 and 4164 had been collected previously, on October 23rd, 1969, 14 km S.E. of Dire Dawa (Ethiopia) along the highway to Harar at an altitude of 1400 m. Reference material has been filed under nr. JM 977 (WAG).
