Glandulicactus (Glandulicactus)
Description
Sclerocactus are ovoid to elongate cylindric, have rigid stems with tubercles that are generally coalesced into ribs, and are covered with spines that come out of the areoles. Most species have at least one hooked spine at each areole. Less often, species may not have hooks. These plants are found in higher elevation deserts such as on the Colorado Plateau, or in the Mohave Desert or the Great Basin. They are well suited to extremes due to lack of rainfall, hot summers and below freezing winters. The Little barrel cactus typically grows in areas where water flows irregularly or depressions where water can accumulate for short periods of time. They are most often found growing along washes and arroyos where their seeds have been subjected to scarification due to water movement, but they oddly also tend to grow along ridges in spots where depressions have formed and can hold water for some period of time.
