Some earlier relevant feedback:
“This is neither Crotalaria juncea or C. mucronata, the two species known by the name san or sann and used as fiber, nor Hibiscus cannabinus (Ambari, patsan, pitwa) yielding mesta or kenaf fiber. It appears interesting.

“I find there is lot of confusion between efloras of Pakistan and China. Pakistan Flora considers H. cannabinus as synonym of H. sabdariffa (with calyx covered with whitish tomentum) and H. gossypifolia with same H. sabdariffa L. as synonym with red fleshy calyx. Flora of China considers H. sabdariffa and H. cannabinus as two distinct species, former with red calyx and latter without red calyx and with white tomentum.
In addition all these species unlobed lower leaves and lobed upper leaves. Your plant seems to have even upper leaves without lobes.
Dr. Gurcharan Singh”
"Based on the Illustration In Eflora ,Org I don't think this can be Hibiscus cannabinus
