Maticana paucicostata

This is truly the smallest of Maticana species, and the slowest. Vivid red flowers are produced repeatedly over the summer.

Denmosa rhodacantha

Denmosa is a South American genus with single variable species. These are mountain plants, becoming tall barrels with age. They also have a very curious-looking flower adapted for humming bird pollination.

Coryphantha sulcata

The young C. sulcata plant, blooming for the second year. The specific name - 'silky' - refers to the white flock that is produced already and with age will cover all the upper part of the plant.

Echinocereus websterianus

Echinocereus websterianus is endemic to a single island in California Gulf, similarly to E. grandis - closely related species found on three other island in the gulf. Administratively the birthplace of E. webstarianus belongs to Sonora state, but I consider it to be one of Baja California species, based more on ecological than administrative divide.
