THE ANATOMY AND DEVELOPMENT OF THE FLORAL ORGANS OF BUGINVILLAEA GLABRA

Comparative histogenesis of vegetative and floral apices inAmygdalus communis, with special reference to the carpel

“…Stage 7, Development Prior to Union of the Carpet Edges.-As cell growth by division and enlargement proceeds on the dorsal side, cell division is initiated in two parallel lines running towards the ventral side; this is the beginning of the rims or edges that will finally unite to give the ventral suture. Cooper (1932) observed this same type of development in Bougainvillea glabra. Such growth results in a slope, as seen in longitudinal section, from the top of the dorsal side to the bottom of the ventral side (figs.…”

“…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).…”
