NATURAL HISTORY OF PLANTS. 



times scandent or voluble, often with hispid iirent hairs; leaves 

 alternate, 2 -stipulate, petiolate penninerved or digitinerved at base, 

 entii-e, dentate, incised or sublobate ; flowers in terminal or oppositi- 

 folious racemes; racemes 2-fid ; branches 1 -sexual; some male; 

 others female ; or oftener 2-sexual ; 1 or few inferior flowers 

 female ; others male co } (All warm regions or rarely mbtempr) 



80. Zuckertia H. Bn.^ — Flowers monoecious ; male bud subpyri- 

 form, shortly apiculate ; calyx 5-partite, valvate. Stamens co (about 

 50) central inserted on conical eglandular receptacle ; filaments free ; 

 cells of extrorse anthers elongate apicidate longitudinally rimose. 

 Female sepals 6-8, 2-seriate imbricate. Germen S-locular ; cells 

 opposite exterior sepals, 1-ovulate ; style more or less flexuose, 

 dilated at apex, afterwards divided in revolute simple branches in- 

 wardly much papillose. Fruit . . . ? An imdershi'ub ( ?) voluble , 

 hairs simple (stinging ? ) ; leaves alternate long petiolate stipulate 

 widely cordate-ovate, penninerved, sub-3-plinerved at base ; flowers 

 in lateral oppositifolious racemes 2-furcate, the branch bearing now 

 male, now female racemes.* {Mexicor') 



81. Leptorachis Kl.® — Flowers, nearly of Zwc^er //«, monoecious ; 

 male calyx valvate, 3-5-partite. Stamens co , central ; filaments 

 free sometimes dilated above ; anthers basifixed elongate, straight 

 or curved, introrsely rimose. Female sepals 5-7, imbricated, some- 

 times pinnatifid ( Ctenomeria ^). Germen, style and fruit as in 

 Tragia. Other characters of Zuckertia.^ — Perennial voluble herbs ; 

 leaves alternate petiolate stipulate, 3-5-nerved ; flowers loosely race- 

 mose ; inferior in axillary or sometimes oppositifolious racemes
