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

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. |
