Gymnocalycium deeszianum cv. YELLOW SUNSHINE
(Syn: Gymnocalycium deeszianum forma variegata)
CACTUSPEDIA       

 


Gymnocalycium deeszianum cv. YELLOW SUNSHINE (forma variegata)
 

Description: The normal G. deeszianum  is a small globose solitary cactus and the variegated form here described only differs from the standard form for the odd yellowish colour of epidermis. The  yellow appearance of this Gymnocalycium is more precisely caused by an aberration called  "schizochromism". Here, though, the specific green pigment (chlorophyll) is partially missing, every other pigment is present at normal levels, the dominant green colouration is lost, but will still more than likely have normal other pigments that give the yellow overall appearance of stems. The yellow colour of this plant is transmitted from the parent to the offspring and this plant is reproduced by seeds.
Stem:
Up to 6.5 cm tall, 8-10 cm in diameter, globose, flattened to elongate, light olive green with diffused yellow fading, becoming a pleasant pale yellowish-green.
Ribs:
Rounded, slightly chinned.
Radial spines:
Spreading, straight to more or less curved and bent against the stem. Creamy yellowish with darker tips.
Central spines: 
0-1 (Often absent).
Flowers:
Pale pink or (usually) pure white.
