Secretory tissues in plants. Date 21 August Erythrina velutina is a species of leguminous tree. There are, approximately, 12 collateral vascular bundles, with cells of thickness circumference with lignified cell walls.

The angular collenchyma Figure 2b is observed immediately under the epidermis with layers of cells. The external cortical parenchyma cells exhibit inter cellular spaces of various dimensions Figure 4a4b. MMBS MSc student and ASCOS undergraduate student contributed in plant sample identification, confection of herbarium, running the laboratory work, analysis of the data and drafted the paper.
