Subspecies 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Euphorbia polyphylla is endemic to sandy habitats in the southern half of peninsular Florida. The species has been reported from coastal Louisiana, but whether those plants represent native occurrences or plantings is unclear (R. D. Thomas and C. M. Allen 1993–1998, vol. 2). The Florida populations are here recognized as the only native occurrences. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
1. Stems, leaves, ovaries, and capsules glabrous; involucral gland appendages absent. | subsp. ocellata |
1. Stems, leaves, ovaries, and capsules pilose; involucral gland appendages present. | subsp. rattanii |
