Acharagma roseana
Acharagma is a genus of two small cacti in northern Mexico.
These cacti are usually solitary but sometimes occur in small clusters. The globose stems tend to be about 3-7 cm in diameter. The ribs have tubercles, with ungrooved areoles. The flowers are at the stem tips, and range from cream to pink and yellow.
The genus is of relatively recent creation, the species originally being described as part of Escobaria, although recognized as a separate section by Nigel Taylor in 1983, and raised to a genus by Charles Glass in 1998.
