The Paullinia, have also flowers irregular or tetramerous, like those of Schmidelia, or more commonly pentamerous, like those of Pancovia and Diploglottis, but the fruit is a piriform septicidal capsule, con- taining one to three seeds (fig. 382, 383), the embryo is thick and fleshy, and the testa, glossy and of dark colour, is furnished, at -P''"'""'" ""^^^^â its base only, with a short cupu- lar-shaped aril. All the species of Paullinia are American and nearly eighty in number, but one or two species are met with in tropical Asia and Africa (where they have perhaps been introduced). They are volubile, climbing plants, with alternate leaves, compound or decomposite, pinnate or digitate, leaves often dentate, flowers arranged in axillary clusters of cymes usually provided with two tendrils below. The , Castanellas, also bindweeds of tropical America, differ very little from the PauUinias with pentamerous flowers (with which perhaps they will soon be united); they have trifoliate leaves and a capsular fruit, at first slightly fieshy, all bristling with rigid prickles. Valen- suelia is a non-climbing shrub from Chili, with the irregular 4-5- VOL. v. "^ -^ Fig. 382. Seed. Fig-. â JSS.
