Foliar epidermal features and their taxonomic significance in Rotala L. (Lythraceae)

The present study deals with the epidermal diversity in nine species of Rotala L. belonging to the family Lythraceae. The leaves are small, variable in shape, size and amphistomatic. The upper epidermal cells are generally larger than the lower epidermal cells; the anticlinal cell walls are wavy or sinuous. The stomata are anisocytic and anomocytic. A peculiar wall thickening at polar end of the stomata is noted in Rotala serpyllifolia. The 2-celled glandular trichomes occur in R. malampuzhensis and the scales in R. floribunda.
