Another Euphorbia decaryi variety

I got it as a cutting and it was introduced here from a Indonesian who made a donation of an assortment of succulents to our local botanical garden. That's as much history that was traceable. It is a very beautiful clone with dark purplish green leaves which is very constrasting. In cultivation, it less robust and slower requiring more shade and less water compared to the type E. decaryi v. decaryi. It also spreads with underground stems which points to either a form of E. decaryi v decaryi or a new species with an affinity with E. decaryi. So far it has not flowered. So far, i have not located photos of this clone on the web.
