Foliar epidermis of nineteen species of Amaryllidaceae, has been studied.
Epidermal cells on both the surfaces are polygonal with oblique or straight anticlinal walls in all species except in Haemanthus and Eucharis where these have sinuous or undulate walls.
Subsidiaries are indistinct and are of C-type. With the exception of Eucharis (hypostomatic) leaves are amphistomatic in all the species.
The stomata are anomocytic. Various types of stomatal abnormalities viz contiguous stomata, interstomatal cytoplasmic connections etc., are observed in the different species.
