Abstract
Anatomical and structural features of two different hydrophytic plant species i.e., Pistia stratiotes L.
(Araceae) and C. asiatica L. Urban Umbelliferae were studied in the present investigation. Samples for this study
were collected from Botanical Garden, GCU, Lahore. The research was based on the investigation of the
anatomical adaptions in plants living in extreme waterlogged conditions. For that purpose Vegetative parts of
plants were studied under scanning electron microscope and light microscope. Single layered epidermal cells
were observed on both sides of the leave’s epidermis with greater number of stomata on the upper layer.
Collenchyma and sclerenchyma, with large intercellular spaces interrupted in the cortical region. Vessels were
observed poorly developed and consisted of protoxylem cells only. In the petiole of C. asiatica (L.) Urban
presence of calcium oxalate crystals was also noted.
