Dear Alok Ji, Haldina cordifolia was originally described by William Roxburgh which is characteristic by the orbicular -cordate leaves, orbicular-oblong stipules, yellow flowers and very peculiar calyx, which are 5-lobed.
Mitragyna parviflora also described by Roxburgh remarkably different from Haldinia cordifolia by the presence of 2 linear-oblong reduced leaves at the base of flower head, obovate stipules, entire calyx limb etc. Leaves are highly variable in later from orbicular, oblong,ovate or cordate hence are not a reliable character for species delimitation.
