 the indéhiscent fleshy fruit, coriaceous or woody, spherical or tri- 

 agonal, has three cells, covered inwardly with hairs and each contain-

with pinnate leaves, the pentamerous flowers (fig. 378-380) are con- 

 structed very nearly like those of l^ancovia, but the fruit (fig. 381) 

 is a loculicidal capsule whose seeds, solitary in each cell, are totally 

 enveloped by a large fleshy aril, coloured and sapid, like that of 

 Euphoria. 



The PauUiiiia, have also flowers ii-regular 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 coloiu-, is fiu-nished, at PmiUima soyiiiu. 



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), 

 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 Paidlinius with pentamerous flowers (with which perhaps 

 they will soon be united) ; they have trifoliate leaves and a capsular 

 fruit, at fii-st slightly fleshy, all bristling with rigid prickles. Valen- 

 zuelia is a non-climbing shrub from Chili, with the irregular 4-5-
