Conophytum armianum (Umdaus)
A tiny nocturnal species that varies in the degree of roughness on the tops of the bodies. It is the only member of section Batrachia, so called because its skin is like that of batrachians (frogs and toads). It is slow and tricky from seed but more manageable when it gets to about 2 years old. Originally discovered by Anthony R. Mitchell whose initials are commemorated in the name.
