Trees , shrubs , climbers [or rarely herbs]. Leaves simple , alternate, rarely opposite or whorled , without stipules, often glandular . Inflorescences terminal , axillary , or at apices of lateral branches, racemose (often paniculate ), corymbose , cymose , umbellate , or fascicled on scaly spur branches in leaf axils . Flowers bisexual or polygamous, rarely unisexual and plants polygamodioecious or dioecious, 4- or 5(or 6) -merous, actinomorphic . Sepals basally connate or free , persistent , usually glandular. Petals basally connate or rarely free, usually glandular. Stamens as many as and opposite to petals, usually adnate to base or throat of corolla tube , sometimes free, rarely united into a tube; anthers 2-celled, dorsifixed , dehiscing longitudinally or by apical slits or pores , rarely transversely septate ; filaments present or absent. Ovary superior, rarely inferior to half-inferior, 1-celled; placentation free-central , sometimes basal; ovules 1 to several in 11 to many rows , usually embedded in placenta, anatropous or semicampylotropous. Style 1; stigma simple or lobed . Fruit drupes with fleshy exocarp or capsules. Seeds 1 to many; endosperm fleshy or horny ; embryo x = 10-13, 23.

About 42 genera and more than 2,200 species: primarily in tropical and subtropical or warm temperate regions of both hemispheres; five genera and 120 species (51 endemic) in China.

Chinese genera of economic value include Ardisia (medicine, oil , edible, wild vegetables), Maesa (edible, tea, dye), Aegiceras (tannin, fine fuel), Embelia (vermifuge, edible), Myrsine (medicine, fine wood , tannin, fuel) .[1]

Genus Maesa

Shrubs or rarely small trees . Leaves entire, serrate, or dentate at margin , usually punctate . Inflorescences racemose, often paniculate ; bracts small; bracteoles 2, usually subtending base of calyx. Flowers 5-merous, bisexual or polygamous. Calyx funnelform, adnate to ovary, lobes valvate . Corolla white or yellowish, campanulate , often punctate-lineate. Stamens free , included . Ovary semi-inferior or inferior, aborted in staminate flowers ; ovules numerous , on a globose free-central placenta. Style as long as or longer than stamens; stigma entire or 3-5-lobed. Fruit globose or ovoid berries or drupes with a crustose endocarp, apex ± covered by persistent calyx, often longitudinally orange punctate-lineate. Seeds small, numerous, angular, embedded in a hollow placenta.

About 200 species: primarily in Old World tropics; 29 species in China.[2]
