sides. — Slirubs often scandent; leaves opposite, 2-glandiilose at base; 

 stipules interpetiolate large, 2-nately confluent ; flowers ' by foiu'S in 

 umbelliform panicles ; the younger each enclosed by a bracteiform 

 ample valvato-connivent stipule ; pedicels below basal joint bracteate 

 and 2-bracteolate. (Brazil.-) 



22. Ryssopterys Bl.' — Flowers (nearly of Banisteria) often 

 1 -sexual; calyx eglandulose. Petals sbortly unguiculate, stamens 

 and gynseceum of Banisteria. Samara3 1-3, laterally tuberculate J 

 superior margin of dorsal wing thicker than the anterior. — Slender 

 volubile shrubs ; leaves opposite or sub-opposite entire, glanduliferous 

 at margin beneath ; petiole 2-glandulose to apex ; stipules rather 

 large ; flowers * terminal or spuriously axillary iu corymbiform cymes ; 

 pedicels articulate, incrassate to apex ; bracts and bractlets 2 imbri-

 8-gIandulose. Stamens 10, most of which are sometimes anantherous. 

 Branches of style produced to an unequally pediform lamina and 

 stigmatose-subcapitate. Gynsjeceum and fruit nearly of Banisteria; 

 cocci dorsally appendiculate with short vertical tuft. — Volubile shrubs; 

 branches compressed ; leaves opposite entire ; petiole 2-glaudulose at 

 apex ; stipiiles minute ; flowers ^ in umbelliform or corymbiform 

 cymes; pedicels articulate at base, bracteate and 2-bracteolate, 

 {Antilles., tropical America^) 



24. Stigmaphyllon A. Juss.^ — Flowers nearly of Banisteria;
