,90.1.] OBSERVATIONS ON THE FLORA OB 1 JAPAN. i)d 



acute at base, disk very thin ; lobes 4, erect-patent or spreading, l|-2- 

 tirnes as long as the tube, ovato-lanceolate or deltoid-lanceolate, subcalloso- 

 acutish at apex, trinerved and usually without veinlets, lateral veins dis- 

 appear before reaching the apex. Petals 4, shorter than calyx-lobes, oblong 

 or obovato-elliptical, shortly attenuated at base, obtuse, 1-nerved with a few 

 loose veinlets, scarcely longer than one-half of the calyx-lobe, thinly mem- 

 branaceous. Stamens 4, shorter than the calyx-lobe, but scarcely longer than 

 the petal, erect ; filament subulate ; anther shorter than filament, oblong. 

 Rudimentary pistil minute and short, with the depressed-globose ovary and 

 the bifid style. Female flowers 1-3-fasciculate, usually shorter than the 

 petiole of leaves of that place ; pedicel gracile, glabrous, 4-8 mm. long. 

 Calyx 4 mm. long ; tube short, obconico-semisphaerical, disk thin ; lobes 4, 

 spreading or erect-patent, nearly thrice as long as the tube, oblong-lanceo- 

 late, ovato-lanceolote, or subulato-lanceolate, attenuated above with an 

 obtuse and subcallose point, trinerved without veinlet, one of lateral veins 

 disappears before reaching the apex. Rudimentary petals and stamens 

 minute and setaceous. Pistil slightly exserted ; ovary globose, longer than 

 the calyx-tube, free, glabrous, 2-3-locular ; ovule solitary in each loculament ; 

 style erect, 2-3-fid, arms shorter than the main portion, patent-arcuate, 

 with the oblong stigma. Fruit globose, muticous, black when mature, 

 eacculent, about 7-8 mm. across, usually with 2 pyrenre, girt with a per- 

 sistent plane calyx-tube at the base : pyrena broadly oblong, black, smooth, 

 indehiscent, thin but cartilaginous, 5-5* mm. long. Seed adherent to 

 pyreme, ovato-elliptical, with a thin testa, thinly but densely opaque-nigro- 

 furfuraceous, deeply sulcate dorsally, the groove close pedicel 4-10 mm. long.
