A rambling, subscandent, perennial undershrub with woody and striate stems. Leavesovate, glabrous. Flowers white in elongated spikes, capsules oblong, pointed coveredwith mucilage and contained in viscid, glandular, persistent calyx tube. (India) Shrubs of perennial herbs, rarely annual, often straggling or subscandent. Leavesalternate, simple, entire, older ones often pale lepidote underneath as a result ofcarbonate exudations, or reduced in flowering stems, petiole often semi-amplexicaulous auriculate; stipules absent. Inflorescence composed of 1-floweredspikelets grouped in a terminal raceme or spike, often united in a leafy panicle.Flowers subtended by 2-3 bracts, 5-merous; calyx tubular, 5-ribbed, often with sessileor stalked glands outside, teeth erect, not enlarged in fruit; corolla funnel-shaped,lobes spreading, blue, red, white or violet; stamen 5, free, filaments broadened at thebase; ovary superior, 1-locular, style 1, stigma lobes 5. Fruit a 1-seeded capsule,included in the calyx and corolla, often splitting from the base with 5 valves. Seedlong, narrowly ovoid, slightly flattened, tapering toward apex, dark brown or black,surface colliculate, hilum small, oval, in a longitudinal depresion. (Indonesia) A creeping herb or scandent shrub up to 2.5m tall, laxly branched; leaves ovate,ovate-lanceolate, elliptical or oblong, 2.5-13cm x 1-6cm, base cuneate, apex acute ormucronate, glabrous, often with white waxy dots below, petiole 2-12mm long, baseamplexicaul, sometimes auriculate; inflorescence a 6-30cm long raceme, rachis withsessile glands; flowers with a green glabrous calyx, covered in stalked glands, corollatube 1.7-2.6cm long, lobes 0.6-1cm x 0.3-0.5cm, white, scented, anthers purple, ovaryand style glabrous. Seed 6mm x 2mm, dark brown. In general preferring a dry seasonclimate, Plumbago zeylanica is almost exclusively found in rather open anthropogenichabitats, e.g. savannah, forest edges and fallow fields, up to 1000m altitude.(Malaysia) A creeping herb or scandent shrub up to 2.5m tall, laxly branched; inflorescence along raceme; flowers with a green glabrous calyx, covered in stalked glands, white,scented.
