I am not a professional nor an expert in these plant groups taxonomy. Any help with ID and spelling are always welcome. Photos are for reference only. To up-date my list I've been using many books, journals, catalogs and other web-sites. It's been helpful, but I have more work to do. I only ship to the main 48 States. I do ship in the winter months. I can add 72+ hour heat packs for $4.00 each.  No international shipping. Please read the front page for ordering information.

   Gymnocalycium damsii monstrose grest sm - This cactus exhibits both "monstrose" (random, lumpy, irregular growth points) and "crested" (fan-shaped or serpentine growth along an elongated line) mutations.

Coloration of the stem is typically green but can develop striking reddish or brownish hues when exposed to sufficient sunlight or under stress conditions. Spines are generally short (up to 12 mm), whitish with darker tips, and often sparse or absent in some parts due to the monstrous form. The parent species G.  damsii produces funnel-shaped flowers, typically white to light pinkish or greenish, and is a very free-flowering cactus. Crested forms may have difficulty flowering or produce unusual crested flowers. These are cutting from one of our old mother. The photo with orange stem is one of our mother plants.

It is still unclear whether this variable complex is one or several species. There is so much variation even in the same population that most authors choose to lump them together. The variety "nidulans" distingushes for the dense covering of stout grey interlacing spines.
