This is somewhat like P. jji^nnata, but the leaflets are 

 narrower and longer and the fruit is smaller and almost 

 equally narrowed to both ends (X. E. Brown). 



Paullinia sp. ? A small specimen, too imperfect for 

 description.

Until the female flowers and fruit of this plant are 

 known, its position in the order must remain uncertain, but 

 possibly its place should be near Stqnndus. In the 

 structure of its very remarkable disc it resembles 

 Lyclinodiscus, Padlk., but that is an African genus and 

 described as having lepidote leaves, funnel-shaped petals, 

 and ten stamens. Mr. Kerr's specimens consist of two small 

 flowering shoots, and bear only male flowers, so that 

 possibly the plant is dioecious (X. E. Brown).
