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

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

 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}) 



42. Simmondsia N^utt.-^ — Flowers apetalous,* 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. Germ en 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 ferous spikes,^ 

 bracteate; the female solitary. [California J)
