Plants annual or biennial, rarely perennial, pilose, strigose, rarely sericeous throughout, hairs tuberclelike or discoid at base. Leaves alternate. Inflorescence a drepanium, elongated after anthesis, bracteate. Calyx 5-parted nearly to base; lobes frequently enlarged in fruit. Corolla light blue, rarely white, campanulate or low salverform; tube short; throat appendages 5, trapeziform; limb 5-parted. Stamens included. Ovary globose, 4-parted. Style not exserted; stigma capitate. Gynobase subulate veined, ca. as long as or surpassing nutlets, rarely shorter. Nutlets 4, adherent to gynobase by entire adaxial rib or only by rib base, erect, homomorphic or heteromorphic; margin of abaxial surface usually with 1(-3) rows of glochids; bases of glochids separated or contiguous or confluent into a wing, rarely reduced to tubercles. Cor salverform or broadly funnelform, the tube about as long as the cal, the throat closed by the fornices; stamens and style included; fruiting pedicels erect or spreading; nutlets erect and connivent, narrowly attached to the elongate gynobase along the median ventral keel (the lower part rounded and free), bearing one or more rows of glochidiate prickles along the continuous dorsomarginal ridge or cupulate border; rough-hairy annuals with erect stems, each branch ending in an elongate, bracteate false raceme (helicoid cyme) of small, blue or occasionally white fls. Ca. 12, mainly N. Hemisphere. Plants annual or biennial, rarely perennial, pilose, strigose, rarely sericeous throughout, hairs tuberclelike or discoid at base. Leaves alternate.
