Description

Family Melastomataceae

Herbs, shrubs , or trees (to 20 m tall), erect , climbing , or rarely epiphytic. Stipules lacking. Leaves simple , commonly opposite and decussate with one of a pair slightly smaller than other, rarely verticillate or alternate by abortion of one of a pair, usually 1-4(or 5) secondary veins on each side of midvein , originating at or near base and anastomosing apically, tertiary veins numerous, parallel, and connecting secondary veins and midvein but in Memecylon secondary veins pinnate and tertiary veins reticulate . Inflorescences cymose , umbellate , corymbose , in paniculate clusters , or a cincinnus, rarely flowers single, fascicled, or born on a spike; bracts sometimes conspicuous and persistent . Flowers bisexual , actinomorphic but androecium often slightly zygomorphic, usually (3 or) 4- or 5(or 6) -merous, perianth biseriate , perigynous; bracteoles opposite, usually caducous . Hypanthium funnel-shaped, campanulate , cyathiform , or urceolate . Calyx lobes (3-) 5(or 6), valvate (rarely connate , but not in Chinese species) . Petals (3-) 5(or 6), equal to number of sepals, distinct , imbricate. Stamens usually twice as many as petals and in 2 whorls, rarely as many as petals by loss of 1 whorl, isomorphic or dimorphic ; filaments distinct, often geniculate , inflexed in bud; anthers typically 2-celled, introrse , basifixed , dehiscent by 1 or 2 apical pores or by short longitudinal slits (Astronia, Memecylon) ; connective often variously appendaged. Pistil and style 1; stigma minute, capitate or truncate . Ovary commonly inferior or semi-inferior, locules usually (3 or) 4 or 5(or 6) with numerous anatropous ovules , rarely 1-loculed and ovules ca. 9 (Memecylon) ; placentation axillary , parietal (Astronia and, outside China, Pternandra Jack ), or free central (Memecylon) . Fruit a dry or fleshy capsule or a berry, loculicidally dehiscent or indehiscent. Seeds (when 3-6-loculed) usually small, curved through half a circle (cochleate) or wedge-shaped (cuneate), in Memecylon seeds large and ovoid ; endosperm absent.

Between 156 and 166 genera (150-160 in Melastomataceae sensu stricto and six in Memecylaceae here considered part of Melastomataceae) and ca. 4500 species (ca. 4050 in Melastomataceae sensu stricto and 450 in Memecylaceae [Olisbeoideae if considered a subfamily of Melastomataceae]) : primarily in tropical and subtropical regions; 21 genera (five endemic) and 114 species (72 endemic) in China.

Chinese genera of economic value include Osbeckia (medicine) and Melastoma (wild fruit and ornamental flowers) .[1]
