This is a common species of the American South-West, also known as Claret Cap cactus. This long-spinned form is common at higher elevations in the area from Zion National Park to Kaibab Plateau, were it sometimes called E. toroweapensis.

Sclerocactus papyracanthus (Toumeya)

This is the smallest Sclerocactus, very different plant compare to any other member of the genus. The plants are known from a large territory, but can be hard to find due to size and good mimicry to the surroundings. It is not very spectacular bur still very desirable among collectors plant, that can reasonably easy grown from readily available commercial seed.

Echinocactus horizonthalonius ssp nicholii

Echinocactus horizonthalonius ssp nicholii name was introduced by Benson for Arizona plants. This is somewhat isolated population (or group of populations), located West of Tucson, with plants virtually indistinguishable from the others belonging to the species. In fact, there are recently discovered Mexican locations where plants do show noticeable different features. Benson had given these plants the special taxonomic treatment based exclusively on the fact that the very old plants here are large and have thicker stems, compared to New Mexico and Texas plants.
