Rank Reasons
Thelypodium flexuosum is a perennial herb occurring in alkaline soils in open deserts of western North America from Oregon and Idaho south to California and Utah. There are 63 estimated occurrences of this species, which are potentially threatened by development, right of way maintenance, and invasive species.
Range Extent Comments
Thelypodium flexuosum occurs in western North America from Oregon and Idaho south to California (FNA 2010) and Utah in the United States (Welsh 2015). Range extent was estimated to be 28,125 square kilometers using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens and photo-based observations documented between 1993 and 2024, it is estimated that there are 63 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Thelypodium flexuosum is potentially threatened by development, rights-of-way maintenance, invasive species, and other threats in some places.
