| Abstract | ||
| This study intends to introduce botanical information about morphological and anatomical characteristics of two species of the genus Physalis namely, Physalis peruviana L. and Physalis ixocarpa Brot. exHornem. The morphological and anatomical attributes of stem, leaf, flower and fruit were studied. Furthermore, scanning electron microscope was used to examine the ultrastructure of trichomes, stomata, pollen grains and seed surface. Results showed that both species are annual herbs with erect, ribbed and solid stems. Leaves are simple and petiolate. Stomata of anisocytic type and various types of trichomes (glandular and non-glandular) were observed. Flowers are yellow, solitary, bell-shaped and bisexual. Pollen grains are monad, tricolporate and lobate. Fruits are fleshy, berry and glabrous included ovoid, flattened and glabrous seeds with lateral hilum. However, the two species varied in a number of morphological characters such as branching, density of trichomes, leaf and pollen grains shape, corolla spots color, and fruit size. These characters have taxonomic importance in distinguishing the genus Physalis L. at generic at species rank of the family. | ||
