Morphological, anatomical, palynological, and micromorphological study on Diplotaxis tenuifolia (Brassicaceae)

Abstract

The present study deals with the morphological, anatomical, and palynological properties of Diplotaxis tenuifolia. The stem cross-sections had a single-layered epidermis, parenchymatous cortex, vascular bundles, and parenchymatic pith cells. An equifacial mesophyll type was observed in the leaves with multiple-layered palisade tissue, but the spongy parenchyma was reduced. Vascular bundles were small except for the midrib. The cross-sections of the fruit had a single exocarp, 3- or 4-layered mesocarp, and single-layered endocarp. Transverse sections of the seed showed the presence of layers of epidermis, parenchyma, and endosperm.
