Abstract
Embryology ofAlysicarpus monilifer D.C. is described. The anther wall comprises the epidermis, the fibrous endothecium, two middle layers and uniseriate glandular tapetum. Pollen is shed at the 2-celled stage. The ana-campylotropus ovule is crassinucellate and bitegmic. The archesporium in the ovule is hypodermal and cuts off a parietal cell. Embryo sac development conforms to the Polygonum type. Endosperm development is nuclear. A chalazal part of the endosperm remains free nuclear and is haustorial in function. Embryogeny conforms to Period I Megarchetype IV and Series B2. The embryogenic classification of the tribe is discussed in the light of the present observation and earlier reports.
