Rank Reasons
Penstemon oliganthus occurs in the southwestern United States in Arizona and New Mexico with around less than 80 occurrences documented. Threats and trends are not well documented for this taxon. There are many occurrences on U.S. Forest Service lands.
Range Extent Comments
Penstemon oliganthus occurs in the southwestern United States in Arizona and New Mexico. Range extent was calculated using herbarium collections and photo based observations (iNaturalist 2021, SEINet 2021). The species is reported from Colorado but these reports are mostly attributed to Penstemon griffinii (Weber and Wittman 2000), however newer specimens, especially those from southern Colorado, should be examined and annotated (SEINet 2021).
Occurrences Comments
Based on herbarium collections and photo based observations, there are less than 80 documented occurrences (iNaturalist 2021, SEINet 2021).
Threat Impact Comments
Potential threats are grazing and forest fire but research is needed to determine if there is an impact.
