 or obovate, I' in length, persistent and crowding at the base, cartilagi- 

 nous or somewhat woody, reticulated, 4- winged, apicolate or 4-toothed at

 more or less villous pubescent or nearly glabrous ; leaves petioled, lan- 

 ceolate, acute, variable in section, runciuate, lyrate, repandly-toothed or 

 nearly entire; calyx-tube elongated, 3'-5' long; petals large, l'-2' long, 

 obcordate, nearly white, becoming rose-color ; capsules sessile or upon

A remarkably stout, caulescent form of this very variable species, 

 collected by Mr. Braudegee near Cafion City, corresponds very nearly 

 to (E. eximia, Gray, PL Fcndl., p. 45. The robust, ascending stems are 

 more than a span high and the capsules sessile, conical, I'-IJ' long, taper- 

 ing upward from a broad base, with 2 wing-crested ribs on each valve. 



(EXOTHERA MISSOURIEXSIS, Sims. Stems low, simple, decumbent ; 

 leaves coriaceous, lanceolate, acute, tapering into a short petiole, ob- 

 scurely denticulate, somewhat canescent when young; flowers axillary, 

 very large, diurnal; tube of the calyx 4 / -7' in length, segments acu- 

 minate, often spotted with purple, much shorter than the tube, about 

 the length of the roundish, flabelliform, mucronulate petals ; corolla 

 4'-t> / in diameter; petals very broad, light-yellow, wjth orange veins; 

 capsule pediceled, very large, somewhat compressed, with 4 broad 

 wings, 2' in length and about the same in breadth including the wings, 

 without the wings 3" in diameter ; seeds large, the undulate crest con- 

 spicuous. Hall d: Harbour, 174. 



(EXOTHERA HARTWEGII, Benth., var. LAVANDUL^FOLIA, Gr. Snffru- 

 ticose, low, hoary-canescent ; stems simple, decumbent, 6' long ; leaves 

 crowded, linear, or oblong-linear, entire, obtuse or acutish, somewhat 

 re volute ; tube of the calyx 1' long, tubular-infundibuliform, many times 

 longer than the ovary and the ovate lanceolate, slightly acuminate 

 segments; petals rhombic-ovate, crenulate, longer than the stamens; 

 stigma discoid ; capsule sessile, cylindrical, canescent; seeds in a double 

 series, horizontal. Canon City, Brandeyee. Bluffs at Pueblo, Greene. 



(ExoTHERA CAXESCEXS, Torr. & Frem. Frem. 2d. Exp., p. 31 5. Gray 

 in PL FendL, p. 44. ((E. yuttulata, Hook.) Stems ascending, 6'-$' high, 

 branching, very leafy to the top; leaves minutely strigose-canesceiir. 

 6" long, oblong-lanceolate or linear, entire or obscurely toothed ; 

 calyx-tube slender, 9" long, purplish, thrice the length of the ovoid, 

 canescent ovary ; petals broadly obovate, entire, ' long, white, with 

 some of each flower conspicuously spotted or blotched with rose-purple ; 

 anthers linear ; divisions of the stigma linear, slender ; capsule slender, 

 cauescent, 3" long and almost as broad, turgid-ovate, apiculate, with 4 

 strongly carinate and almost winged angles, the intermediate ribs
