A. retusus LRM332, hilltop
habitat at Puento el Oregano.
Comments
An old Charles Glass location for the species (Gl.& F 2267).
Plants grow here on the tops of low hills and on south westerly facing
slopes together with Thelocactus conothelos and Turbinicarpus
valdezianus. The plants are mostly single and are of a typical
‘fufuraceus’ type having pointed equilaterally triangular tubercles, they
differ considerably in morphology from the longer tubercled population to
the south at Huizache. As with many other habitats the slopes are
extensively graze by goats.
