Seems more of an arabicum to me as it does not have a spherical caudex that belongs to an obesum,also the profuse branching is typical of an arabicum although I may be wrong.

I would say 'obesum'.

These days there is so much inter breeding that one could assume a cross, but more than likely obesum.

You would definitely have a more decisive identification by leaves and bloom.

Thanks to both Sinha and Rick.

Appreciate your info.

Will wait till it blooms to confirm identity.
