Abstract

The taxonomic value of trichome and its systematic and phylogenetic relationships are well known. The
present study is an attempt to document the different types of trichome and their distribution in certain
species of Leucas R.Br. Fresh plant specimens were collected from different locations of Kerala, and
micro-preparations of trichomes from leaves as well as stem peelings were observed. The surface of all
species of Leucas studied was entirely covered by trichome. All the trichomes are uniseriate in nature
while the number of cells may vary to uni, bi, or multicellular. All trichomes possess pointed apex.
L.aspera possess two types of trichomes; non-glandular, uniseriate,1-3 celled in abundance and
glandular, 2-5 celled stalk with rounded tip in scanty. Remarkable variation exists with respect to the
length of the trichome in different species of Leucas. The smallest trichome was observed in Leucas
linifolia. The present study indicated that there exist diversity in both distribution and morphology of
trichomes in species of Leucas.
KEY WORD: Trichome, Leucas, Lamiaceae, Kerala.
