Abstract
The morphology of trichome study was carried out in some species of
Staurogyne (Acanthaceae) from Peninsular Malaysia. Three taxa studied are S. argentea,
S. merguensis and S. setigera var. setigera. The aim of this study is to identify and describe
the morphology of trichomes and the methods used are sectioning using sliding microtome,
leaf clearing, epidermal peels and observation under both light and scanning electron
microscopes. Findings have shown variations in trichome morphology which can be used in
species identification. Three forms of trichome were recorded, papillae, glandular and
non-glandular. The results showed 12 types of trichome present in Staurogyne. Two types
of glandular peltate trichomes, terminal unicellular and terminal multicellular. While
for non-glandular trichomes they are simple multicellular and simple unicellular. In
conclusions, the findings have shown that trichome morphology has taxonomic significance
and can be used in identification of species studied.
