STYLOSANTHES DISSITIFLORA. Much branched from near the 
base, 8-10 inches high, copiously beset with soft brownish setose 
hairs: sheath of the stipules 1} lines long, equalling the subulate seti- 
form appendages: free portion of the petiole 1-1} lines long: leaflets 
linear lanceolate, sharply acuminate, somewhat narrowed but obtusish 
at the base, glabrous on both surfaces, strongly ciliate, 4—6 lines long, 
3-1} lines broad, veins prominent beneath: flowers scattered, pinkish : 
stipe of the calyx 13 lines long, divisions of the limb obtuse, ciliate : 
standard obovate-orbicular, retuse, 3 lines in length: ale obovate with 
very slender auricles: fruit not seen. — Dry rocky soil, Rio Blanco

CoryLEpDoN suBRIGIDA. Glabrous, 14-2 feet in height: leaves 
radical, sessile, ovate, acute, 3—4 inches long, two thirds as broad: stem 
and branches covered with a light bluish bloom: bracts of the stem

long, with about 8 spreading somewhat rigid racemosely 5-7-flowered 
branches : flowers large (3 inch), approximate, borne on the upper 
side of the branches : pedicels a line or two in length: sepals lanceo- 
late-acuminate, half the length of the petals; the latter lanceolate-acu- 
minate, acutely keeled, somewhat gibbous at the base, red, internally 
tinged with yellow: stamens nearly equalling the corolla. — Ledges 
and cliffs, Tultenango Cafion, State of Mexico, October, 1892 (n.

SEpuM PrRINGLEI, Wats. var.? minus. An inch or less in height: 
inflorescence more dense: antheriferous stamens only 5. — Bare earth, 
summit of the Nevado de Toluca, September, 1892 (n. 4240). Per-

to the acuminate tip, roughened by minute hairs and somewhat =
