Mammillaria luethy forma cristata

	Mammillaria luethyi forma cristata	CACTUS ART NURSERY Cultivation and Mail Sale of Cacti and Succulents.

Cristation in this plant is unstable and defasciation occurs all the times.
That is the linear meristem turns into a number of small apical meristems that form normal shoots.

The defasciation is a process leading to longitudinal cleavage of a linear crest, rather to the complete division of the stem into individual normal shoots. Crests may remain at any stage for a long time. But at the stage of brain-shaped crest when the curves begin to crowd defasciation occurs rather often. That is the linear meristem turns into a number of small apical meristems that form normal shoots. More seldom defasciation occurs without any reason at an earlier stage of the development of the crest.
