Astrophytum myriostigma f. crested monstrous

The crested shape of this cactaceae has a fan crest that is never the same in plants and also due to its monstrous shape has abnormalities of the shape or lack of thorns, characteristics that make it unique and very sought after by collectors. In its normal form it is an exemplar of a globe-shaped cactus that with time can become columnar. Its epidermis is green and entirely covered by white dots. It can have three to ten (more commonly five) well marked ribs, with a border well delineated by the white fluffy areoles, which with time assume a yellowish colouration. During the spring at the apex of the plant grow large funnel-shaped inflorescences, entirely yellow.
