This plant is over 30 years old. We do not know the name... Can you help? The flower was deep purple and star shaped when it opened. Thanks!!
The specific species may be difficult to identify without seeing the flower, as the stapeliad group is a large one with many hybrids. For example, this site http://www.shoalcreeksucculents.com/stapeliads.html has many varieties, but is still a small representation of the group. Perhaps you can recognize yours amongst the photos on this web page. Mark.
It IS Huernia schneideriana. Its very common in cultivation. Look at the faded flower. It has the typical "Huernia points"!!!
Steve, can you tell me what the major differences are between the 2, as I often get them mixed up. Ed
