Arisaema consanguineum Schott in Bonplandia (Hanover) 7: 27. 1859 .

Lectotypus (designated here): India. Sikkim: Cherrigtum, 1500-1800 m, 21.V.1849, fl., J.D. Hooker s.n. (CAL [CAL0000001307]!) (Fig. 1).

Notes. – Arisaema consanguineum is morphologically close to A. erubescens but can be easily distinguished by its green spathe limb extending into a long tail (vs. a striped pinkish spathe limb devoid of long drooping tail in A. erubescens) and fruiting peduncle nodding upon maturity (vs. erect fruiting peduncle).
