Habit: Perennial herb, +- glabrous (except ciliate leaf, sepal margins). Leaf: opposite to subopposite. Inflorescence: flowers generally 1 in leaf axils. Flower: calyx lobes long, slender; corolla tube funnel-shaped, lobes asymmetric; filaments free, attached near top of corolla tube, sharply bent near base, unappendaged, anthers held around top of but free from stigma, each partly sterile, pollen +- free; nectaries 2, alternate ovaries, wide-spaced, generally not exceeding ovaries; style cylindric, widened distally, stigma skirted at base. Seed: glabrous.
Species In Genus: 6--7 species: southern Europe, northern Africa, to Afghanistan. Etymology: (Latin: possibly, to bind or wind about)
Unabridged Note: 2n=46 in Vinca minor, Homo sapiens, and Lepus europaeus (and other hares), not suggesting a close relationship among these taxa, yet supporting the idea that classification should be based on more than one kind of evidence.
