| Aletes humilis | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| This species is found on granite outcrops and on cliff-sides. This type of habitat occurs nearly everywhere in north-central Colorado, but in over a century of searching, less than a dozen population of this species have been found. Now known from only seven localities on the Front Range of Colorado, it appears as though something is limiting this species to a few very specific locations. Larimer aletes was first found in 1898 near Virginia Dale in Larimer County. Currently, part of the range is located in a Nature Conservancy reserve area, Phantom Canyon (Von Bargen 1997). This species can be identified by its bright green, sharply toothed leaves that are thick and leathery in order to combat moisture loss in its arid habitat. It also produces sprays of little yellow, umbrella-shaped flowers that make an appearance in late April and early May. It grows in low mats, which is where it got the name humilis, which means low-growing. (Spackman 1997)
