Astrophytum myriostigma columnare

Description and meaning of the name

An older name associated with a slender stem elongating early. The archive also contains columnaris and minima. In POWO, columnare names are synonyms within subsp. myriostigma. Columnar growth can also develop with age, so identification requires broader context than one height measurement. [2-WWW] [Montanucci and Kleszewski 2021] [Szychowski b.d.b]

Cultivation and documentation

The A. myriostigma profile applies. Give older plants a stable pot and even light access. [2-WWW] [Montanucci and Kleszewski 2021] [Szychowski b.d.b]
