Taxonomic Comments
This record is for Draba pectinipila as recognized in Flora of North America (2010, vol. 7), which is also followed by Goodrich and Huber (2016), distinguishing it from D. oligosperma, but including D. juniperina, saying that D. juniperina is "indistinguishable from the type collections of the earlier-published D. pectinipila." Kartesz (1994) included D. juniperina in D. oligosperma.

Rank Reasons
Wyoming Whitlow-grass (Draba pectinipila) occurs in the Uintah Mountains and Green River area, and the Greater Yellowstone area of the western United States, in northeastern Utah, northwestern Colorado, and western Wyoming, it is estimated that there about 24, and between 21 and 80 occurrences rangewide. It occurs in Colorado on the Dinosaur National Monument, in Utah on Ashley National Forest and Flaming Gorge National Recreation Area, and lands of the BLM without special protective designation, and in Wyoming on the Absaroka-Beartooth Wilderness, and lands of the BLM without special protective designation.
Range Extent Comments
Wyoming Whitlow-grass (Draba pectinipila) occurs in the Uintah Mountains and Green River area, and the Greater Yellowstone area of the western United States, in northeastern Utah, northwestern Colorado, and western Wyoming. Range extent was estimated to be 32,000 square kilometers, using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1992 and 2023 (Flora of North America Editorial Committee 2010, GBIF 2023, iNaturalist 2023, NatureServe 2023, SEINet 2023).
Occurrences Comments
Based on NatureServe Network occurrence data, herbarium records, and photo-based observations of Draba pectinipila documented between 1992 and 2023, and anecdotal evidence, it is estimated that there about 24, and between 21 and 80 occurrences rangewide (GBIF 2023, iNaturalist 2023, NatureServe 2023, SEINet 2023).
