Placentation in Barclaya 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 two large, separate cotyledons. Weberbauer's contention that Barclaya should be retained at the generic level in the Nymphaeaceae is supported.
