460 NATUBAL HISTOEy OF PLANTS. 



sides. — Shrubs often scandent ; leaves opposite, 2-glaiidulose at base ; 

 stipules interpetiolate large, 2-ii.ately confluent ; flowers ' by fours 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 shortly unguiculate, stamens 

 and gynseceum of Banisteria. Samarse 1-3, laterally tuberculate; 

 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 in corymbiform cymes ; 

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

 cate. {Warm Oceania}) 



23. Brachypterys A. Juss.® — Mowers nearly oi Banisteria ; calyx 

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

 Branches of style produced to an unequally pediform lamina and 

 stigmatose-subcapitate. Gynseceum and fruit nearly of Banisteria ; 

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

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

 apex ; stipules 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; 

 calyx 8-glandulose. Stamens 10, of which 6 are fertile; but the 

 4 alternipetalous are sterile or rudimentary, sometimes minutely 

 petaloid; filaments glabrous, connate at base; anthers glabrous or 

 exappendiculate or setiferous at apex. Gerraen and styles of 

 Brachypterys ; apex stigmatose unciform or unequally pediform more 

 or less foliaceo-dilated. Samarse 1-3 (nearly of Banisteria),
