Comments

Alpine stitchwort is quite common in the Watershed, collected from all mountain regions, growing mainly in the alpine and subalpine, although occasionally plants can be found at lower elevations. In the South San Juan Mountains, Sharples (2017) found it "on open subalpine ridges and slopes and throughout the alpine zone." This Rocky Mountain and Cascades plant is also common in the mountains of the Rio Grande drainage of New Mexico (down to the border with Texas). The new genus name, Cherleria, comes from Dillenberger and Kadereit (2014), who on DNA analysis disaggregate the old genus Minuartia into eleven genera (see also Sabulina macrantha and Sabulina rubella).
