DOAIGEY AR
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.
