The swollen trunk of the Pachycormus discolor covered with exfoliating, white, papery bark. The botanical genus name refers to that trunk, it comes from the Greek for "thick stump". The discolored peeling white bark, protects a green under-layer that will maintain photosynthesis when the tree is dormant. It is an excellent caudiciform plant forming a fat branching trunk at an early age. The tree becomes a ball of light pink flowers in mid summer. Below are some photos of specimen Pachycormis discolor taken at recent cactus and succulent plant club shows.
