Locally rather plentiful, Triteleia montana appears to have a disjunct distribution in the Sierra Nevada range north and south from Yosemite, though future collections may bridge the gap between the distributions currently indicated. Molecular data suggest that it is related to T. lemmoniae of Arizona (J. C. Pires 2000).
