  Gymnocalycium mihanovichii CACTUSPEDIA       

 


Gymnocalicium mihanovichii (var. filadelfiense)
This plant’s most unique characteristic is its colourful body ( greyish-green with white and red highlights)
 

Description: The plant is considered to be a miniature cactus. It only grows to be 4 cm high and has a 5-6cm diameter
Flowers of this species have a silky appearance and  range from white, greenish/tan to pink.

Remaks: Gymnocalycium friedrichii
  and G. stenopleurum
are sometimes combined with G. mihanovichii, and sometimes kept as separate species. G. friedrichii  and G. stenopleurum are quite districted of  from G. mihanovichii , ut many intermediate forms are also known and nowadays it is suggested that all should be combined into only one variable species.

Recognized subspecies, varieties and forms:

  • G. friedrichii has prevalently purplish pink, wide open flowers and well-pronounced polymorphism of spines. Besides it has tall slender ribs and roller-shaped prominent thickening around areoles.

  • G. mihanovichii has wider, lower ribs, in juvenile plants divided into separate chins, in maturity every rib have flat surface and a pleat above each areole. But the essential thing is its pale or brownish-yellow, not fully opening flower.

  • G.stenopleurum Ha white, fully opening flowers.

Notes:
Furthermore a number of readily distinguished multicoloured and variegated cultivars (cv. NISHIKI) only partially de-coloured) are now available. Some of this plants can be grown on their own roots and are very beautiful.
