Taxonomy and cytology of the genus Albuca (Hyacinthaceae) in East Africa

The following taxa are represented in East Africa (Kenya, Tanzania, Uganda): Albuca kirkii (Bak.) Brenan (2n = 18), A. abyssinica Murr. (2n = 18, 36), A. tenuis Knudtzon sp. nov. (2n = 18). The general haploid karyotype is 3L + 6S. The two first species are fairly heterogenous, with characteristic facies in local populations, but with little or no constant correlation of characters over wide areas. Infraspecific incompatibility is observed, but only slightly combined with differences in morphology or level of ploidy.
