Tephrosia angustissima is known from Brevard and Miami-Dade counties.
Tephrosia angustissima, T. corallicola, and T. curtissii have been regarded as distinct species (L. H. Shinners 1962e; R. W. Long and O. Lakela 1967); D. Isely (1982, 1998) considered them a single species. These three taxa are sympatric with apparently few, if any, morphological intermediates. They are part of the T. purpurea complex (see discussion under 14. T. tenella).
