The narrow distributions and imperiled habitats of these south Florida endemic Euphorbia species emphasize the importance of taxonomic assessment. We assess E. ogdenii as being a G1 (= Critically Imperiled) species, E. hammeri a G2 (= Imperiled) species, and E. porteriana (s.s.) and E. garberi G3 (= Vulnerable) species.
