Description

Family Gentianaceae

Herbs [shrubs or small trees ], annual , biennial, or perennial . Stems ascending , erect , or twining . Leaves opposite, less often alternate or whorled , simple , base connate ; stipules absent. Inflorescences simple or complex cymes, sometimes reduced to sessile clusters , often in a thyrse or 1-flowered. Flowers bisexual , rarely unisexual , 4 or 5 (or 6-8) [-12]-merous. Calyx tubular , obconic, campanulate , or rotate, lobes joined at least basally. Corolla tubular, obconic, salverform , funnelform , campanulate, or rotate, rarely with basal spurs; lobes overlapping to right or rarely valvate in bud; plicae (extensions of the corolla tube between the lobes) present or absent. Stamens inserted on corolla tube or occasionally at sinus between corolla lobes, alternate with lobes; anthers basifixed or dorsifixed , 2-locular. Nectaries absent or attached to ovary base or corolla. Ovary usually 1-locular at least apically, rarely 2-locular due to intrusion of a lamellate placenta into locular cavity . Fruit a 2-valved capsule, rarely a berry. Seeds many or rarely few, small; endosperm abundant [scant in saprophytic genera].

About 80 genera and 700 species: worldwide; 20 genera and 419 species in China, of which two genera and 251 species are endemic.[1]
