Plumbago scandens L.[1]

Plumbago zeylanica, commonly known as Ceylon leadwort, doctorbush[2] or wild leadwort,[3] is a species of plumbago with a pantropical distribution. Carl Linnaeus described the paleotropical P. zeylanica and neotropical P. scandens as separate species, but they are currently considered synonymous.

Appearance[edit]

Plumbago zeylanica is a herbaceous plant with glabrous stems that are climbing, prostrate, or erect. The leaves are petiolate or sessile and have ovate, lance-elliptic, or spatulate to oblanceolate blades that measure 5-9 × 2.5–4 cm in length. Bases are attenuate while apexes are acute, acuminate, or obtuse. Inflorescences are 3–15 cm in length and have glandular, viscid rachises. Bracts are lanceolate and 3-7 × 1–2 mm long. The heterostylous flowers have white corollas 17–33 mm in diameter and tubes 12.5–28 mm in length. Capsules are 7.5–8 mm long and contain are reddish brown to dark brown seeds.[1]

Habitat and range[edit]

Plumbago zeylanica grows throughout the tropical and sub-tropical climates of the world,[4] including Australia and India. In Australia, it grows in the understory of monsoon forests and vine thickets from sea level to 900 m.[5] In Dhofar, Oman, this species is often found growing on Olea trunks.[6]

Ecology[edit]

P. zeylanica is a food plant for the Cassius blue (Leptotes cassius), Marine blue (L. marina), and Zebra blue (L. plinius) during their larval stages.[5][7][8]

Traditional medicine[edit]

Early folk medicine used the crushed plant internally and externally as an abortifacient as well as a treatment for leprosy.[6]
