Herbs perennial , biennial, or annual , less often lianas, shrubs , or trees , usually bristly or scabrous-pubescent. Leaves simple , exstipulate , alternate, rarely opposite, entire or serrate at margin . Inflorescences often double scorpioid cymes, rarely solitary; bracts present or absent. Flowers bisexual , actinomorphic , rarely zygomorphic. Calyx usually 5-parted or lobed , mostly persistent . Corolla tubular , campanulate , rotate, funnelform , or salverform ; tube appendages 5, rarely more, mostly trapeziform, rarely absent, sometimes a ring of hairs present; limb usually 5-parted; lobes overlapping, rarely twisted in bud. Stamens 5, inserted on corolla tube or rarely at throat , included or rarely exserted; anthers introrse , 2-loculed, usually dorsifixed at base , less often medifixed , dehiscence longitudinal . Nectaries at base of corolla tube or on disc below ovary. Ovary superior, 2-carpellate; locules 2 and each with 2 ovules, or 4 and each with 1 ovule; ovules nearly atropous , semianatropous, or anatropous . Style terminal or gynobasic , branched or not. Gynobase flat, fastigiate , or subulate . Fruit 1-4-seeded drupes or nutlets (mericarps) ; nutlets mostly dry, often ornamented with wings , prickles and/or glochids (stiff bristles with barbed or anchorlike tips ) . Seeds vertical or oblique , coat membranous; embryo straight, less often curved ; cotyledons flat, fleshy .

About 156 genera and 2500 species: temperate and tropical regions , centered in the Mediterranean region; 47 genera and 294 species in China, of which four genera and 156 species are endemic.[1]

Genus Heliotropium

Herbs annual or perennial , rarely subshrubs , pubescent or strigose , rarely scabrous . Leaves alternate, less often opposite, sessile or petiolate . Cymes terminal , rarely axillary , unilateral , scorpioid, bracteate or not. Calyx 5-parted. Corolla white or light bluish purple, less often yellow, cylindric or funnelform , strigose outside, glabrous and rarely appressed pubescent inside; throat frequently pubescent; limb 5-parted; lobes orbicular , sometimes linear , margin with folds or undulate . Filaments extremely short; anthers included . Ovary completely or incompletely divided into 4 lobes; ovules 4. Style terminal; stigma conical or ringlike. Fruit nutletlike dry drupes, without evident mesocarp at maturity, endocarp bony, dividing into 4 1-seeded or 2 2-seeded mericarps. Seeds straight or curved , usually with a thin endosperm.

About 250 species: tropical and temperate regions ; ten species in China.[2]
