These are largely restricted to subcoastal counties of the Gulf plain, but their genetic influence extends considerably inland in Texas and into var. fasciculata. Var. puberula exhibits local and regional variation. Britton and Rose (1930) accepted the variants as species; some were reduced to synonymy by Pennell (1917) and by Pullen (1963), but others maintained as sympatrie species or varieties. This procedure is unsatisfactory because the variants blend extensively with each other and with sym patrie var .fasciculata. Some years ago in coastal Jackson and Harrison cos. in Mississippi, I conducted a brief analysis of populations of Cassia fasciculata possessing pubescent leaflets. The following pubescence forms were observed: (1) stems, pedicels, pods with spreading pubescence, (2) stems and pedicels with incurved hairs, pods with spreading pubescence, (3) stems with incurved hairs, pedicels and pods spreading pubescence, (4) stems, pedicels, pods all with incurved hairs. Some populations were represented entirely by one of the above phenotypes, others were mixtures. It is possible to deliniate 3 aspects of var. puberula that approximate taxa of other authors.
