... upper and lower epidermises formed of more or less rounded cells, with a thin cellulose wall (figures 1-c, 1 -b). It is covered by a thick cuticula. The round sub-epidermal collenchyma is formed by several layers of thick cellulose-walled cells in the protruding parts of both sides ( Fig. 1-a, b, c). The cortical parenchyma is found next. It is made up of several layers of large, rounded to polygonal thin-walled cells, leaving inter-cellular spaces between them. It is rich in chloroplasts. A single secretory duct is located between the phloem and the lower epidermis (1-c) which is characteristic of Apiaceae (Perrot, 1944). This ...
