I would have been happy to photograph this threatened species endemic to Ganjam district, but I am afraid S. roxburghii has much longer petioles and petiolules and the flowers  are white or greenish white.

Schefflera venulosa var venulosa and var. roxburghii, both are Jharkhand and I have seen one of them here in Uttarakhand and then Chattishgarh too and during my recent trip to south too.. Dont know the difference between them.
Earlier var. roxburghii was actually a different species, S. roxburghii, and it is reported in the Flora of Madras Presidency.
I just returned from my two days trip to Rajaji, so will check later, to confirm, but yes, there are many species growing in garden some of which are exotic.
Regards
Pankaj

Kew List recognises S. roxburghii as recognised species with Schefflera venulosa var. roxburghii (Gamble) K.K.Khanna as its synonym.

I read that it is  listed as threatened species.

So both Schefflera venulosa and S. roxburghii are accepted and both are found.
Please recheck your link, it shows LEAST CONCERNED and not Threatened!!
Haines reported both plants from Bihar and Orissa and Clarke too.
I have seen many plants but never could differentiate.
Hence S.chefflera venulosa cant be endemic to south India.
