Stem Botanical Studies of Markhamia Platycalyx (Baker) Sprague

Family Bignoniaceae is one of the richest families in secondary metabolites. It includes many genera of high economic and medicinal values. One of the important plants of this family is Markhamia platycalyx (Baker) Sprague. Reviewing the available literature, nothing could be traced concerning the botanical features of M. platycalyx. This provoked the authors to carry out both macromorphology and micromorphology investigations of it. These various diagnostic characters could be helpful in authentication and identification of M. platycalyx stems.
