394 NATURAL HISTORY OF PLANTS. 



lobed cupule (augmented connective ?) ; anthers basiflxed, 2-dymous ; 

 cells subglobose or shortly ovoid erect, dehiscent to apex by liaear 

 short or poriform mouth. Gynseeeum free, surrounded at base by 

 cupular unequally-3-5-dentate disk ; teeth sometimes ^-fid ; germen 

 2-3-locular, style apical ; apex stigmatose subentire, acute or more 

 rarely 2 -lobed. Ovules in cells 2, inserted at internal angle ascendent 

 more or less completelyanatropous; micropyle extrorse inferior. Fruit 

 drupaceous or finally subdry, indehiscent or more rarely hence hardly 

 dehiscing, obliquely subglobose, whence sometimes subearinate 

 ( Ophiocaryon) ; putamen osseous or crustaceous. Seed ascendent ; 

 cotyledons of exalbuminous embryo more or less conduplicate or 

 much ( Ophiocaryon) contortuplicate ; radicle incurved short or long 

 thick {Phoxanthus) or flexuous and dilated at apex ( Ophiocaryon). — 

 Trees or shrubs ; leaves alternate, simple or pinnate ; folioles entire 

 or serrate ; flowers in much ramified compound cymiferous racemes 

 often bracteate. {Trop. and subtropical Asia and America). See p. 346. 



III. SAPINDE^. 



5. Sapindus Plum. — Flowers regular hermaphrodite or poly- 

 gamous ; receptacle usually depressed. Sepals 4, 6, imbricate. 

 Petals same in number alternate, imbricate, inwardly naked or oftener 

 enlarged above the claw by 1 , 3, glabrous or variously pilose scales. 

 Disk clothing receptacle and externally annular or cupular encircling 

 on all sides interior stamens. Stamens (in female flower effete) 10, 

 2-seriate of which 5 are alternipetalous, longer, or 4-8, or more rarely 

 11-00 ; filaments hypogynous free, often pilose ; anthers introrse 

 versatile, 2-rimose. Germen (rudimentary in male flower) 3- or more 

 rarely 2-4-looular,2-4-lobed; style terminal, 2-4-lobed stigmatiferous 

 at apex. Ovules in cell solitary, situated at base of internal angle 

 ascendent anatropous ; micropyle extrorse inferior. Fruit 1-4- 

 coccous ; fertile cocci 1-4, globose or oblong, fleshy or coriaceous, 

 indehiscent, sterile cocci at base 1-3 minute stipate. Testa of 

 exarillate exalbuminous seed membraneous or crustaceous ; hilum 

 wide ; cotyledons of straight or curved embryo thick fleshy ; radicle 

 short incurved penetrating more or less within testa. — Trees or 

 shrubs sometimes scandent ; leaves alternate exstipulate ; simple or 

 1-00 -foliolate pinnate ; folioles entire or rarely serrate ; flowers in
