Stem Anatomical Descriptors of Four Sesbania Scop. Species And Their Systematic Implication

Stem anatomical features of four Sesbania Scop. species viz. S. bispinosa (Jacq.) W. Wight, cannabina (Retz.) Poir., sesban (L.) Merr., and rostrata Bremek. & Oberm., were examined to add some insights for identification these using quantitative descriptors. stem is composed epidermis, cortex, vascular tissues – phloem, cambium zone xylem, pith, which exhibit significant variations among the in terms their area thickness. showed largest widest epidermal cells. The close relationship between was found Moreover, closer extent according descriptors; also rationalizing external morphological similarities species. A dichotomous key studied made. Dendrograms based on Agglomerative Hierarchical Cluster analysis descriptors confirmed relationships identified previous phylogenetic analyses. Bangladesh J.
