Our recent visit to Cactus Garden Panchkula further clarified the identity of Succulent shrub or tree like Euphorbias. I realised that in my earlier post in November 2010, I had mixed up photographs of two different species: E. antiquorum and E. trigona.
I am uploading them now separately.
Here are photographs of E. antiquorum have 3-4 winged stems, with wings running almost straight but constricted into segments; ridges of wings somewhat dentate, spines in pairs, up to 6 mm long; leaves 2-5 cm long, obovate, orbicular to obovate-oblong, early caducous.
related species E. lactea has stems with white band on the faces between the wings.
