Astrophytum coahuilense

Coahuila, Mexico

 

It looks like A. myriostigma, but softer, has more white flecks that cover the plant, the flowers are yellow with a characteristic red throat, although can appear pure red or very seldom pure yellow like in this one, and are very sweet-scented.

A. coahuilense and A. myriostigma when cross-pollinated are fruitless: they are sterile by each other.
