Tabish, you have a keen eye, keep it up
Jacobinia species are now placed in genus Justicia. Eflora of pakistan
describes Justicia tinctoria. Flora of Guetemala and Ecuador describe both
J. spicigera and J. tinctoria. Former has fusiform unopened corolla and
ovate leaves, latter narrowly funnelform corolla and elliptic leaves. Ours
matches with J. tinctoria. I hope you will agree.
