styles 2, distinct from the base, subulate; stigmas simple or capitate. 
Capsule globose, ellipsoid or ovoid, membranous, usually septicidally 
2-valved. Seeds many, minute. Herbs or undershrubs, sometimes 
spinous, glabrous or softly glandular-pilose. Leaves alternate, entire. 
Flowers blue, usually in peduncled bracteate cymes, which from a 
panicle, sometimes in axillary clusters or racemes. 
Species about 20, spread widely in the Tropical and Temperate regions 
of both hemispheres.

Flowers regular or nearly so. Calyx free, of 5 rarely 4 or 6 
or more divisions or teeth or rarely irregularly split. Corolla with 
a long or short tube, and 5 rarely 4 or 6 or more lobes, imbricate 
or induplicate in the bud. Stamens as many as corolla-lobes or 
very rarely fewer, inserted in the corolla-tube and alternate with 
its lobes; anthers 2-celled, the cells opening in longitudinal slits 
or rarely in terminal pores. Ovary superior, entire or 4-lobed rarely 
2-lobed, either 4 or 2-celled with 1 ovule in each cell or 2-celled 
with 2 ovules in each cell (in all cases formed of 2 carpels); style
