Leaf surface characters of four Haplophyllum species; H. blanchei, H. buxbaumii, H. poorei and H. tuberculatum, have been investigated using scanning electron microscopy (SEM). Presence of hair, cuticular pattern and characters of stomata shape, size and arrangement has been considered. H. poorei and H. blanchei have sufficient quantity of hair on both surfaces, while H. buxbaumii and H. tuberculatum have only in leaf margin. Stomata shapes in all taxa are elliptical and sunken.
