Description
PLATE CXVII Dalea melantha Schauer var. cineracea Barneby and var. berlandieri (Gray) Barneby, relatively rare and local varieties of the widely dispersed Mexican D. melantha, figured in typical form on Pl. CXVI. The var. berlandieri, sympatric with var. melantha northward from San Luis Potosi but ranging beyond it into Coahuila, is ideally distinguished by the few (2 or 3) pairs of large and broad leaflets combined with a loose raceme of flowers, but is not always strongly marked. The var. cineracea, known from one station in northern Oaxaca, where it occurs on andesitic bedrock in the oak- belt, differs from var. melantha in its many (7-10) pairs of gray-silky leaflets. See also caption to Pl. CXVI. — Stems × 1; the rest × 5. var. cineracea: 1) flowering branchlet; 2) stipules; 3) leaflets; 4) interfloral bract, ventral and dorsal views; 5) flower; 6) banner, ventral view; 7) keel. var. berlandieri: 10) flowering branchlet; 11) leaflets.
