Abstract
Placentation in B. longifolia Wall. (Nymphaeaceae) is laminar. Each ovule is bitegmic and crassinucellate. A small embryo sac of the Polygonum type is formed from which a tubular, haustorial-like projection is produced into the surrounding perisperm. Mature seeds are spinate and exarillate. The mature embryo is minute and bears 2 large, separate cotyledons. Weberbauer''s contention that Barclaya should be retained at the generic level in the Nymphaeaceae is supported.This publication has 1 reference indexed in Scilit:
