Vernacular names

Acharagma is a genus of two cactus species from northern Mexico.[1]

Description

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.
Species

As of December 2021, Plants of the World Online accepts two species.[1] A third possible species, A. huasteca, described in 2011, is considered to be a synonym of Acharagma roseanum subsp. galeanense.[2]
