in length, oblong, rounded at the apex and base, glabrous, glandular- 
punctate beneath: spikes elongated, terminal, very loosely flowered;

bracts ovate, acuminate, glabrous, caducous, 3 lines long: calyx very 
villous, resinous-dotted between the ribs, 3-4 lines long; the teeth 
filiform, plumose, much longer than the tube: corolla light-colored with 
purple glandular dots; keel 4 lines long. — Collected upon limestone 
hills, Villar, San Luis Potosi, 14 September, 1893 (no. 5472). 
DaLeEa vuniroLtiata. Slender, smooth, annual, with spreading 
branches from near the base, a span to a foot in height . stem glandular- 
punctate: leaves strictly unifoliate; petioles 3-4 lines long; leaflet 
broadly ovate, truncate or subcordate at the base, rounded at the apex, 
glandular-crenate; the larger ones 6-7 lines long, equally broad : 
racemes terminal or nearly so, 2-3 inches long; pedicels 4 line in 
length: calyx turbinate, finely pubescent with curved hairs along tea 
prominent nerves, and ciliate upon the margin, nearly 2 lines long:

dry, thin soil, barranea of Tequila, Jalisco, by Mr. Pringle, 6 October, 
1893 (no. 4585). A very attractive and well marked species, which 
has long been represented in several herbaria by Miiller’s specimens, 
for which, we find no description.

or obtuse and often apiculate at the apex, grayish with a fine appress 
pubescence upon both surfaces, tawny upon the midrib beneath, 11-14
