Abstract

The investigation deals with the reproductive behaviour in Eremopogon foveolatus (Del.) Stapf, a member of the tribe Andropogoneae. The magaspore mother cell or the products of its meiotic division degenerate in a majority of ovules and four–nucleate unreduced embryo sacs are formed from the surrounding cells of the nucellus. Eight–nucleate reduced embryo sacs are also formed in some ovules but the percentage of such ovules is very low. The unreduced egg develops parthenogenetically but fertilization of the polar nucleus appears to be essential for the formation of endosperm.
