3!U NATURAL HISTORY OF PLANTS. 



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

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

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

 ciipularunequally-3-5-dentate disk; teeth sometimes 2-fld ; germen 

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

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

 more or less completely anatropous; micropyle extrorse inferior. Fruit 

 drupaceous or finally subdry, indehiscent or more rarely hence hardly 

 dehiscing, obliquely subglobose, whence sometimes subearinate 

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

 cotyledons of exalbuminous embryo more or less conduplicate or 

 much {Ophiocaryon) contortuplicate ; radicle ineui'ved short or long 

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

 Trees or shiaibs ; 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 hermaphi-odite or poly- 

 gamous ; receptacle usually depressed. Sepals 4, 5, imbricate. 

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

 enlarged above the claw by 1, 2, glabrous or variously pilose scales. 

 Disk clothing receptacle and externally annular or cupular encu-cling 

 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-c/j ; filaments hypogyuous free, often pilose ; anthers introrse 

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

 rarely2-4-locular,2-4-lobed; style terminal, 2-4-lobed stigmatiferous 

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

 ascendent auatroj^ous ; 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 

 cxarillate exalbuminous seed membraueous or crustaceous ; hilum 

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

 short iucurved penetrating more or less within testa. — Ti'oes or 

 shrubs sometimes scandent ; leaves alternate exstipulatc ; simple or 

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