“…Subsequently, they progress along the obturator surface, an outgrowth of cells that is covered by a layer of secretory unicellular papillae, extend over the entire surface of the funicle, placenta, and ventral wall of the gynoecium, and contact the micropyle, although some variation occurs between species. A single transmitting tract has been mentioned previously for Bougainvillea spectabilis (Joshi, 1934; Joshi and Rao, 1934) and a funicular obturator in Pisonia aculeata (Venkateswarlu, 1947) and Bougainvillea glabra (Cooper, 1932).…”
