SIS NATURAL HISTORY OF PLANTS. 



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

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

 entire, dentate, incised or sublobate ; flowers in terminal or oppositi- 

 folious racemes ; racemes 2-fld ; branches I -sexual ; some male ; 

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

 female ; others male oo } (All warm regions or rarely sfuhtemp}') 



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

 form, shortly apiculate ; calyx 5-partite, valvate. Stamens cx3 (about 

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

 cells of extrorse anthers elongate apiculate longitudinally rimose. 

 Female sepals 6-8, 2-seriate imbricate. Germen 3-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 undershrub ( ?) voluble , 

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

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

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

 male, now female racemes.* {Meadco.^) 



81. Leptorachis Kl.^ — Flowers, nearly of Zuckertia, monoecious ; 

 male calyx valvate, 3-6-partite. Stamens oo , 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 ia 

 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
