1. Vincetoxicum hirundinaria Medicus, Hist. Comment. Acad. Elect. Theod. Palat. Mannheim Phys. 6:404. 1790. Markgraf in Tutin et al., Fl. Europ. 3:72.1972; All & Khatoon l.c. 61.


  • Asclepias vincetoxicum Linn.
  • Cynanchum vincetoxicum (Linn.) Pers.
  • Vincetoxicum officinale Moench

    Stem erect, up to 120 cm long, puberulent to subglabrous. Leaves 6-10 x 2.5-5 cm, ovate to ovate-lanceolate, subglabrous to pubescent, specially on veins and margins. Petiole 5-11 mm. Flowers 6-15 clustered in leaf axils. Calyx 1.5 mm long, lobes linear, pubescent. Corolla glabrous within, white, yellow or greenish. Corona lobes sessile. Follicles 5-7.5 cm x 8 mm, fusiform, acuminate, glabrous.

    Fl. Per.: May-July.

    Type: Described from Scandinavia.

    Distribution: Most of Europe including European Russia, West Siberia, Turkey, Caucasus. Kashmir, Pakistan (Hazara, Waziristan), Himalayas up to Sikkim (Hooker f., l.c.).

    This is a very variable species in which some workers (Markgraf l.c.) have reognised a number of subspecies, others (Pobedimova in Fl. U.R.S.S. vol. 18.1952) have treated some of these as species. I have accepted this taxon in a broader sense.

    ‘Duthie 15766’ from’ Waziristan, Kaniguram, 6500 ft’ looks different and needs further study.
