Colchicum (Suranjan-e-Shireen) سرانجن شیریں

Colchicum / Suranjan-e-Shireen (سورنجان شیریں) also known as Colchicum Autumnale, is a herb with very narrow leaves, broadening towards the tip, brownish fleshy underground stems, large yellow flowers and fruits with recurved tips.

The chief constituent of colchicum is the alkaloid, colchicines, which occurs in the form of yellow flakes, crystals or as a whitish-yellow amorphous powder. Its odour resembles the hay when dampened and warmed.
