Hoodia flavum

     I could find little information about this plant except for a few pictures of small star shaped purplish black flowers. It was sold to me by Bachs Cactus Nursery as Trichocaulon flavum which is synonymous with Hoodia flavum. It certainly looks like a Hoodia though the flowers are smaller and a little different. It's also a much darker green than my other Hoodias.
