the germen, iu female flower short ; filaments free, in male flower 

 far exserted and propending downwards through the space inter- 

 mediate between the two anterior sepals unequal ; anthers introrse 

 (effete in female flower), 2-rimose. Germen (rudimentary in male 

 flower) obliquely inserted at the bottom of the disk, 3-locular ; style 

 subulate ; apex stigmatose scarcely or not dilated slightly curved ; 

 ovules in cell 2, oblique subsuperposed, covered with a small ob- 

 turator. Fruit ^ capsular subglobose-3-gonalsubpergameneous, with 

 3-valved cell ; seeds in each cell 1, 2, oblique, minutely arillate ; testa 

 osseous nitid; cotyledons of exalbuminous spirally convoluted embryo 

 foliaceous. — Trees or shrubs ; leaves alternate, 1-3-foliolate ; folioles 

 serrate ; flowers ^ axillary pedunculate solitary or racemose few. 

 ( Western mountains of South America.^) 



44. Xanthoceras Bge.'— Flowers polygamous regular; sepals 

 5, equal, imbricate. Petals 5, alternate, unguiculate esquamate 

 slightly membranous ; in prœfloration tortuous or imbricate, corru- 

 gate at apex. Disk slight, interior to petals, very shortly annular 

 and before the sepals far produced to 5 elongated horns, recui-ved at 

 apex and increased at base by short thick scale. Stamens 8, interior 

 to disk, 4 of them alternipetalous, a little longer ; filaments free ; 

 anthers introrse glandulose-apiculate, 2-rimose. Germen (in male 

 flower rudimentary) central, 3-locular; style straight, stigmatose 

 at apex, capitate-3-lobed ; ovules in cell to 8, iu two series super- 

 posed subtransverse ; raphe subhorizontal interior. Capsule thick 

 corticate, obovate-3-gonal obtuse, with 3-valved cell; valves in 

 middle septiferous within. Seeds cc , oftener few subglobose ; testa 

 glabrous (black); hilum broad; cotyledons of exalbumiuons embryo 

 thick. — Small trees ; leaves alternate imparipiunato ; folioles 

 serrate ; flowers ^ (appearing before the leaves) racemose ; each 

 rather long-pedicellated ia axil of bract ; " bracteoles 2, lateral, on 

 longer or shorter pedicel. (Northern China,'') 



' Rather large. 6 Rather large showy ; petals white, at base
