locular ; styles 2, 3, entire or 2-lobed at apex ; ovules 2 (of Buxus) 

 closed to micropyle. Fruit baccate or finally subdry, indéhiscent ; 

 seeds and other characters of Buxus (or Pachysandra).- — Shrubs 

 (evergreen); branches terete; leaves alternate exstipulate entire, 

 penninerved or oftener 3-plinerved to base ; flowers ' in racemes or 

 axillary spikes ; the female inferior. (Southern Asia, Sumatra, 

 Java. 2 ) 



42. Simmondsia Nutt. 3 — Flowers apetalous, 4 1-sexual ; male 

 calyx 4, 5-partite, imbricate. Stamens 10-12, 2-seriate, 5 inserted 

 in depressed receptacle ; filaments free short ; anthers ovately oblong 

 extrorse ; cells adnate, longitudinally rimose. Female calyx 4, 5- 

 partite ; folioles connivent to base dilated concave, attenuated at 

 apex, imbricate, persistent. Germen free shorter than calyx conoid, 

 3-sulcate, 3-locular, crowned with 3 thick subulate papuliferous re- 

 curved branches of style. Ovules in cells solitary descending ; 

 micropyle introrsely superior. Capsules loculicidal, often 1-sper- 

 mous, columelliferous in the centre; columella filiform, 3-partite, 

 persistent. Seed descending ; " cotyledons of exalbuminous embryo 

 thick; radicle short superior." — Evergreen shrubs more or less 

 villose ; leaves opposite entire coriaceous penninerved exstipulate ; 

 flowers axillary; the male in short ramosely glomeruli fer ous spikes, 6 

 bracteate; the female solitary. (California. 7 ) 



43. Styloceras A. Juss. 8 — Flowers monoecious ; the male nude. 

 Stamens oo (5-30) ; filaments free very short, centrally inserted on 

 suboblique receptacle ; anthers erect basifixed, introrsely 2-rimose ; 

 apiculate at obtuse apex. 9 Female sepals 4-10, unequal, 2- or 3- 

 cussate, imbricate. Germen free sessile, 2-3-locular; style 2, 3,
