This is a medium sized tree distributed in the Western Ghats as well as in north-eastern<br />

India. <strong>The</strong> leaves and bark are aromatic. Baruah et al. (1999a,b) carried out an ethanobotanical<br />

study and chemical examination of many plants belonging to this species<br />

and identified four chemically distinct types (chemovars). <strong>The</strong>y are linalool, citral,<br />

cinnamaldehyde and methyl cinnamate types. Morphoplogically, linalool type is closely<br />

related to citral type, while cinnamaldehyde and methyl cinnamate types are similar.<br />

Linalool and citral types always have comparatively smaller leaves and their panicles<br />

are comparatively shorter than or rarely equal to the leaves in comparison to the leaves<br />

and panicle characteristics of the other two types. Baruah et al. (1999a) also found
