  • Description

    PLATE LXVIII Dalea nemaphyllidia Barneby and D. escobilla Barneby, herbaceous or weakly suffrutescent herbs, glabrous up to the flower-spikes, with smooth, virgate stems up to a meter tall branching distally into an open panicle. Each is known from a single locality in the oak-pine belt at ± 1000-1200 m in Nayarit, D. escobilla from Cerro de San Juan near Tepic, D. nemaphyllidia from Yxtlan. The flowers, appearing in the fall and winter months, are similarly bicolored, the banner whitish or largely so, finally rubescent, the inner petals rose-purple. The short-toothed calyx, externally glabrous but fringed about the mouth with silky hairs, distinguishes D. escobilla from closely related D. polystachya (Pl. LXVII) and the many leaflets from D. mcvaughii (Pl. LXIX). No other Mexican dalea has the long, truly linear-involute, glaucous leaflets of D. nemaphyllidia. — Inflorescences, and detached leaf of D. nemaphyllidia × 1; pods, and leaf-rachis of D. nemaphyllidia × 10; the rest × 5. D. escobilla: 1) branch of panicle; 2) stipules; 3) leaflet, dorsal view; 4) flower + bract; 5) banner, profile and ventral view; 6) wing; 7) keel; 8) androecium; 9) pod. D. nemaphyllidia: 1) branch of panicle; 2) primary cauline leaf; 3) segment of leaf- rachis + petiolule; 4) bracts, dorsal and profile views; 5) flower; 6) banner; 7) wing; 8) keel; 9) androecium; 10) pod.
