Abstract

Pogostemon cablin is also known as patchouli or nilam. This species is an aromatic plant which has economic importance due to its essential oil which is widely used as raw material for the perfume industry. This study was conducted in order to determine the types, anatomy and micromorphological features of the trichomes (glandular and non-glandular) on the patchouli leaf lamina. The findings of this study showed that there were eight distinct types of trichome (two non-glandular and six glandular trichomes). The non-glandular trichomes are simple unicellular and multicellular. The glandular trichomes are short-stalked capitate, long-stalked capitate, peltate, digitiform, clavate filiform and fusiform.
