Here are some differences
T. cordifolia T. sinensis (T. malabarica)
Shoots glabrous Shoots pubescent
Leaves glabrous Leaves pubescent above, tomentose beneath
Leaves 3-7 cm Leaves 10-15 cm long
Drupes red, 8 mm across Drupes crimson, 1.2 cm across
Endocarp smooth Endocarp tubercled
What had caused confusion in my mind was eFlora of Pakistan which considers T. cordifolia auct. (particularly Hook.f. & Thoms, i.e. Flora of British India) to be T. malabarica,silently ignoring the features of T. malabarica. Flora of China considers T. malabarica to be synonym of T. chinensis and clearly mentions pubescent branches and leaves, larger leaves (7-14 cm x 5-13), semiovoid drupes (longer than broad) with tubercles.
After going though eFlora of Pakistan I have been watching my specimens in Delhi which belong to T. cordifolia, and never found any trace of pubescence. I also noted an interesting thing. The Specimens in Delhi, which grow in in natural Ridge forest have smaller leaves never more than 8 cm or so and do produce flowers and fruits, whereas the specimens in city on fences and trees may have leaves up to 15 cm or even more, and it is difficult to find flowers and fruits on them. I had uploaded my photographs some time back. I am attaching them again here for comparison.
