Abstract

The morphotypes and chromosome numbers of Euphorbia hyssopifolia and Euphorbia heterophylla from Ile-Ife, Nigeria are reported for the first time. Mitotic studies carried out on both species revealed a diploid chromosome number of 2n = 12 and 2n = 28 respectively. The results indicate that the two Euphorbia species studied belong to the members of the genus Euphorbia with the secondary system of basic chromosome number of X = 6 and X = 7 (respectively) resulting from aneuploidy and polyploidy.
