Hello Garg ji.

On this page: https://efloraofindia.com/efi/thespesia-populnea/ ... I spotted two places where we need correction.

They are incorporated from following posts:

1. https://groups.google.com/g/indiantreepix/c/TJk7LBvR_6w/m/EfYUKSJCP9UJ
Last two photos are of T. populneoides ... they need to be removed.
... Oct 13, 2009 at Vaghbil, Thane
.. Dec 7, 2010 at Vaghbil, Thane

2. https://groups.google.com/g/indiantreepix/c/ZAa0b920Yww/m/8JUUrTJyu8gJ ... this one is T. populneoides to me.

All other observations on the page remain T. populnea as listed.

At the end of page are listed my observations  T. populneoides: and T. populnea... they are respectively correctly listed.

Regards.

Dinesh

Hello Garg ji,

About the differences, here are some bits I collected and summed up: 

Thespesia populnea and Thespesia populneoides are similar in that they are both trees or shrubs with showy flowers, but they have some differences in their leaves, fruits, and seeds:

Leaves:
Thespesia populnea has heart-shaped leaves that are shiny and alternate, while
Thespesia populneoides has spirally arranged leaves that are light green and triangular heart-shaped.

Fruits:
Thespesia populnea has mature fruits that are easily broken, while
Thespesia populneoides has mature fruits that are not broken (outer fruit splitting into 5 segments, exposing indehiscent inner fruit) ...
Thespesia populneoides fruit pedicels are normally long and often hanging.

Seeds: 

Thespesia populnea has broadly ovate seeds, while 

Thespesia populneoides has narrowly ovate seeds.

Reference: Fosberg, F. Raymond; Sachet, Marie-He´le`ne (1972) - Thespesia populnea (L.) Solander ex Corrêa and Thespesia populneoides (Roxburgh) Kosteletsky (Malvaceae)

I find Viplav ji's post Dehiscent fruits in the Thespesia populations of Mumbai - VG-JUL-10 has touched on this subject long ago ... where he puts his thought: "a large number of the Thespesia strands in Mumbai appear to intergrade between T. populnea and T. populneoides." and ends his post seeking comments and observations.

Regards.

Dinesh
