Kartesz, J.T. 1999. A synonymized checklist and atlas with biological attributes for the vascular flora of the United States, Canada, and Greenland. First edition. In: Kartesz, J.T., and C.A. Meacham. Synthesis of the North American Flora, Version 1.0. North Carolina Botanical Garden, Chapel Hill, N.C.
Taxonomic Comments
As treated here (following Kartesz, 1999), Chamaesyce chaetocalyx (and its var. triligulata) are excluded from C. fendleri, leaving here only the typical variety of a broadly treated C. fenderi (as was done in the 1994 Kartesz checklist). The Flora of North America (vol. 12 2016) transfers Chamaesyce fendleri to Euphorbia fendleri; these represent the same concept for the element.

Rank Reasons
Fendler's Broomspurge (Euphorbia fendleri) occurs in western North America, in the United States from southwestern South Dakota to California and Texas and northern Mexico. The range extent was estimated to be 3.2 million square kilometers, and there are estimated to be more than 1500 occurrences.
Range Extent Comments
Fendler's Broomspurge (Euphorbia fendleri) occurs in western North America, in the southwestern United States from southwestern South Dakota to California and Texas and northern Mexico. Range extent was estimated to be 3.2 million square kilometers, using herbarium specimens and photo-based observations documented between 1992 and 2023 (Flora of North America Editorial Committee 2016, GBIF 2023, iNaturalist 2023, SEINet 2023, Villaseñor 2016).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1992 and 2023, it is estimated that there are more than 1500 occurrences rangewide (GBIF 2023, iNaturalist 2023, SEINet 2023).
