Fam. 160. MYRSINACEAE Yabu-koji Ka Myrsine Family 



Mostly small evergreen shrubs or small trees, sometimes suffrutescent undershrubs; leaves simple, usually alternate, rarely op- 

 posite, entire or toothed, without stipules; inflorescences axillary or in terminal panicles, racemes, or fascicles, often on special 

 articulating lateral branches; flowers bisexual, sometimes unisexual, 4- to 5(-6)-merous, white or pink; calyx persistent, 4- to 

 5(-6)-lobed; corolla gamopetalous, campanulate, cup-shaped, or rotate; stamens inserted on corolla-tube or at the base, always 

 opposite the lobes, the anthers longitudinally splitting or opening by pores; ovary superior or semi-inferior (in Maesa only), 

 1-locular, the ovules 1 to many, imbedded in a basal or free central placenta; style simple, the stigma entire, lobed, or fringed; 



fruit a drupe or berry; seeds 1 or many (in Maesa), the endosperm fleshy or horny. About 25 genera, with about 1,000 



species, chiefly in tropical and subtropical regions. 



lA. Ovary and fruit semi-inferior; flowers bibracteolate; seeds many 1. Maesa 



IB. Ovary and fruit superior; flowers without bracteoles; seeds solitary, globose. 



2 A. Corolla-lobes dextrorsely contorted; flowers bisexual; inflorescence paniculate, corymbose, or subumbellate 2. Ardisia

I. MAESA Forsk. Izu-senryo Zoku 



Erect or decumbent, evergreen shrubs or small trees; leaves toothed or entire, glabrous or pubescent, usually glandular within; 

 inflorescence terminal or axillary, racemose or paniculate; flowers small, bisexual or unisexual, 5-merous, with 2 bracteoles at 

 base or on the pedicels; calyx-lobes persistent on sides or near apex of semi-inferior ovary; corolla tubular, cup-shaped or cam- 

 panulate, the lobes glandular-striate within; stamens inserted on the corolla-tube, the filaments distinct, nearly as long as the 

 ovoid to reniform anthers; ovary with a globose placenta, many-ovuled; style columnar, slender, the stigma entire or 3- to 



5-lobed; fruit a globose to ovoid, fleshy berry; seeds small, many, angular. About 100 species, chiefly in the Tropics of the
