E. cannabinum sensu Hook. f., Fl. Brit. Ind. 3: 243. 1882, non L. 1753; R. R. Stewart, Ann. Cat. Vasc. Pl. W. Pak. & Kashm. 746. 1972. E. cannabinum L. ssp. asiaticum Kitamura var. heterophyllum (DC.) Kitamura in Acta Phyt. Geobot. 32: 139. 1981; Uniyal in Hajra et al., Fl. Ind. 12: 352. 1995.

Type:

Holotype: Brazil:  anon., s. d. (G–DC, G00495651)

Distribution:

China, Nepal, Bhutan, Maynamar, India, Pakistan (Kashmir).

Comment/Acknowledgements:

A rare species in our area, Kashmir seems to be its western most limit.

There is difference of opinion in the species circumscription, King & Robinson in their Monograph Syst. Bot. 22: 1–581, 1987, have adopted a broader view of E. cannabinum L. and treated E. heterophyllum DC. as synonym of the former taxon. Whereas Kitamura l. c. treated it as a variety of E. cannabinum ssp. asiaticum. However, Chen, Y. L. et. al., l. c. 2011 accepted both the taxa as distinct species on the basis of leaf characters. In E. cannabinum L. the leaves are irregularly lobed with serrate to undulate margins, whereas in E. heterophyllum leaves are 3–5–lobed or sect with regularly and deeply incised–crenate margins which are not undulate. We have adopted the view of Chen, Y. L. et. al., l. c. and treated E. heterophyllum DC. as a distinct species.
