The leaves in all the spevcies are amphistomatic and anomocytic except Oxalis corniculata where anisocytic stomata are more common than anomocytic; the latter condition being common in all the species studied.
Stomatal indices, frequencies, trichome types and sizes have been determined. The significance of these characters has been discussed in species identification.
