General  
Morphological

A herb 0.3 - 1.2 m tall. Roots biennial tuberous, paired, whitish or green. Leaves ovate- cordate to rounded, the upper ones clasp the stem. Lowest leaves deeply lobed and long stalked. Flowers bright blue usually in lax spike like cluster with very variable bracts greenish purple conspicuously dark veined. Follicles 5, 16- 8 mm long, shortly hairy erect. Seeds obpyramidal, blackish brown.

Flowering

August-October

Fruiting September-November
History  
Parts Underground roots and stems
Status Critically endangered
Phytochemistry

Roots of the plant yield several alkaloids-  heterophyllisine, heterophylline and heterophyllidin [4]; heteratisine, atisine, atidine, F- dihydroatisine, isolatisine, hestisine, hetidine and hetisinone have also been isolated [5].

Agrocultivation

It thrives well in cool climate and a well- drained loamy soil. Propagation is done either by divisions of roots or from seeds. If the roots are used for propagation then the roots are dug up after the stems have died down. The larger ones are used for drugs whereas smaller ones are used for propagation. If the seeds are used for propagation, they should be sown soon after harvesting. Plants have been obtained via somatic embryogenesis in Calli derived from in vitro raised leaf and petiole explants of A. heterophyllum (through Tissue culture). Complete plantlets are formed after 4 weeks and are transferred to the field.
