SAPINDAOEM. 413 



the germen, in 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 feinale 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 iu 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 prsefloration 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, reciirved 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 &, in two series super- 

 posed subtransverse ; raphe subhorizontal interior. Capsule thick 

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

 middle septiferbus within. Seeds oo , oftener few subglobose ; testa 

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

 thick. — Small trees ; leaves alternate imparipinnate ; folioles 

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

 rather long-pedicellated in axil of bract ; ® bracteoles 2, lateral, on 

 longer or shorter pedicel. {Northern China.'')
