I am not familiar with native (wild-growing) Schefflera plants.
My posted plant is based on Shrikant ji's ID.
In Western Ghats, peninsular India towards n-e India, we have Heptapleurum venulosum
(Wight & Arn.) Seem. ... synonym of Schefflera venulosa
from what I found in Cooke's flora
This species seems to be distributed to a larger extent than other.
Other natives distributed are (referenced from eflora of China and Nepal) -- for later reference:
Schefflera elliptica (Blume) Harms
shrub - (perhaps n-e India), Taiwan, Indo-China to Australia.
Schefflera pubigera (Brongn. ex Planch.) Frodin (syn. Schefflera bengalensis Gamble)
Himalayas to s-c China
Schefflera elata (Buch.-Ham.) Harms
tree - 1800-2100m Himalaya (Kumaun to Bhutan), Assam, Burma, s-w China
Schefflera impressa (C. B. Clarke) Harms
tree - 2000-3400m Himalaya (Kumaun to Bhutan), s-w China
Schefflera hypoleuca (Kurz) Harms
tree - Dense forests; ca. 1300 m. s China, India, Myanmar, Vietnam
Schefflera racemosa (Wight) Harms
tree - endemic s Western Ghats
Looking at the purple rachis of your posted (and potted) plant, it could be Schefflera venulosa
The reasoning is weak, please consider it as a guess.
