Abstract
The morphology and types of trichomes on the leaves, stems and floral parts of Lavandula stricta Del., (= L. coronopifolia Poir.) and L. coronopifolia Lam., were investigated. Both the species showed nonglandular trichomes with cells having warty walls. The two species also have glandular trichomes with unicellular, bicellular or multicellular heads. Nonglandular trichomes with smooth cell walls and branched glandular trichomes were not observed in L. coronopifolia. ne trichomes of the two species could be grouped into 8 types comprising of 17 forms of nonglandular and 13 forms of glandular trichomes.
