Astrophytum ornatum niveum virens and nudum

Description and meaning of the name

Niveum and virens occur in historical descriptions of more hairy and greener plants respectively. Nudum is used in the catalogue to describe reduced hairs. Age and natural hair abrasion affect appearance. The accepted species remains A. ornatum, with older names retained as aliases or phenotype labels. [2-WWW] [Bartylak 2007] [11-WWW]

Cultivation and documentation

The A. ornatum profile applies. Assess the form using more than the old lower stem alone. [2-WWW] [Bartylak 2007] [11-WWW]
