Common names include plumbago and leadwort (names which are also shared by the genus Ceratostigma). DescriptionThe species include herbaceous plants and shrubs growing to {{convert|0.5|-|2|m|ft|abbr=on}} tall. The leaves are spirally arranged, simple, entire, {{convert|0.5|-|12|cm|in|abbr=on}} long, with a tapered base and often with a hairy margin. The flowers are white, blue, purple, red, or pink, with a tubular corolla with five petal-like lobes; they are produced in racemes. The flower calyx has glandular trichomes (hairs), which secrete a sticky mucilage that is capable of trapping and killing insects; it is unclear what the purpose of these trichomes is; protection from pollination by way of "crawlers" (ants and other insects that typically do not transfer pollen between individual plants), or possible protocarnivory.[2] Mature plumbago leaves often have a whitish residue on their undersides, a feature that can confuse gardeners. While this white material resembles a powdery mildew disease or a chemical spray deposit, it is actually a natural exudate from "chalk" glands that are found on the Plumbago species.[3] TaxonomyThe generic name, derived from the Latin words plumbum ("lead") and agere ("to resemble"), was first used by Pliny the Elder (23-79) for a plant known as μολυβδαινα (molybdaina) to Pedanius Dioscorides (ca. 40-90).[4][5] This may have referred to its lead-blue flower colour{{Citation needed|date=October 2014}}, the ability of the sap to create lead-colored stains on skin,[6] or Pliny's belief that the plant was a cure for lead poisoning.[7] The following species are accepted by The Plant List:[8] {{div col|colwidth=18em}}
