4«0 NATURAL HISTORY OF PLANTS. 



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

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

 umbelliforni panicles ; the younger eacb 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-sexiial; calyx eglandulose. Petals shortly unguiculate, stamens 

 and gynœceum of Banisteria. Samarœ 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 corymlnform cymes ; 

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

 cate. ( Warm Oceania.^) 



23. Brachypterys A. Juss." — Flowers nearly oï Banisteria ; calyx 

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

 Branches of style produced to an unequally pediform lamina and 

 stigmatose-subcapitate. Gyneeceum 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-braeteolate. 

 (Antilles, trojncal America.^) 



24. Stigmaphyllon A. Juss.'-' — Flowers nearly of Banisteria; 

 calyx 8-glauilulosc. 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. Germen and styles of 

 Brachypterys ; apex stigmatose unciform or unequally pediform more 

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