Requesting to please provide ID of the plant captured at Ooty Bot. Gdn. in November 2013.
It was found growing on a tree.
i just do not know any round leaved crassulaceae plant that has such inflorescence...
may be a portulaca?
Attaching some cropped pics of the flowers and leaves...
It is Kalanchoe sps.
yes that is a distinct possibility
i have been searching my brains out for 4 petaled flowers of succulent leaved plants ... but the growth habit of the stalk throws me
it may be the place and where/ how its growing...
Kalanchoe sp. is definitely a good fit
I wonder what would it do and develop as if planted if a cutting or even a leaf were to be transplanted in a well drained sandy soil, like any old kalanchoe?
Unfortunately, a year before the tree where you have clicked the pictures fall down on glass house and it is under renovation. 
The good thing is, we are able to locate the same plant in a rock garden, and along the Ghat side towards Canoor, apparently it is naturalized. 
A further search revealed the plant is listed in the checklist of Ooty Botanical Garden and Flora of Tamil Nadu as Crassula quadrifida (Crassulaceae). It is a synonym of Crassula multiclava and probably from South Cape. How it has been introduced is unclear!. It is a beautiful plant.

Requesting to please ID this orchid captured in Ooty Botanical Gardens in November 2013.
My first sighting of a wild orchid.
It doesn't seem like an Orchid to me.
This is a Crassulaceae (stonecrop) member.
It may be Kalanchoe sp. of crassulaceae
Crassula multiclava as per another thread.
