Male meiosis of E. clandestina has indicated presence of seventeen bivalents at metaphase I, and segregation of 17: 17 chromosome at anaphase I and II, followed by normal pollen and seed fertility. This indicates that E. clandestina possesses a new gametic chromosome number (x=17). This basic chromosome number (x=17) has not been recorded in the genus Euphorbia, so far.In the present report, the probable origin of the new basic chromosome number has been interpreted in the light of relevant literature.
