Comments
Native of the sw. US and Mexico, introduced in FL, AL, TN, NC, VA, and other states to the north. This species is similar to Euphorbia dentata Michx. and is mapped by Kartesz (2011 BONAP North American Plant Atlas) for several counties in sw. Virginia. The basis for these records is not known, but a recent examination of material in the UR herbarium by Dr. W. John Hayden revealed several specimens of E. davidii that had been misidentified as E. dentata. Our suspicion is that E. davidii is established in Virginia as an adventive weed. Closer examination of all E. "dentata" specimens in herbaria is warranted.
Habitat
Ruderal areas similar to that occupied by E. dentata. Virginia specimens have been collected along RR tracks, in disturbed soil along riverbanks, on roadsides, and on the edges of parking lots.
