Xerophyte

Description

Normally A. asterias seedling have the standard 8 ribs, while only a small number of them have few or more ribs. The form with only five ribs, is particularly rare because many of the 5 ribbed seedlings that occasionally appear will usually develop additional ribs in a few years as they age. So it is quite exceptional to see an old A. asterias with five stable ribs. This form however looks suspiciously hybridized with myriostigma or coahuilense and probably is not a pure 100% asterias.
