Mandragora caulescens
''Mandragora caulescens'', the Himalayan mandrake,〔 is a perennial herbaceous plant in the family Solanaceae, native to the Himalayas and mountainous regions of Myanmar and south-west China. One of the differences from the other species of ''Mandragora'' is that it has a stem, whereas they are stemless. Like all species of ''Mandragora'', it contains tropane alkaloids, making it toxic. It is used in traditional Chinese medicine.

The flowering period is from April or May to July or September, with fruits appearing until October. The flowers are borne singly on stalks (pedicels) long. The sepals are joined at the base to form a lobed cup-shaped structure, often nearly as long as the petals. The petals are dark purple or yellow, similarly joined at the base with lobes about half their length of . The stamens are joined to the base of the petals, and vary considerably in length, with the anthers long. The fruit is a berry, greenish white to yellow in colour, up to across. The numerous seeds are yellow to light brown, long.〔〔
