Embryo Sac Development in Moquiniella

Abstract

THE Loranthaceae are characterized by extremely long embryo sacs the tips of which reach up to various lengths in the style1. In four genera—Barathranthus2, Helixanthera3, Tapinostemma4, and Tupeia5—they invade the stigma ascending as far as its apex. While working on Moquiniella rubra (Spreng. f.) Balle, a species endemic to South Africa, we observed that the tip of the embryo sac not only ascends up to the apex of the stigma but also elongates further and curves downward.
