126 GENTIAXACEiE. Frasera. 



* * * Leaves with cartilag-inous white margins, thickish, lanceolate or linear: glands on the 

 corolla-lobes solitary, but sometimes 2-lobed. 



•i— Capsule turgid; its valves strongly convex: seeds elongated-oblong, thickish, scabrous, mar- 

 ginless: corolla-lobes with a double longitudinally adnate crown contlueut with the gland : in- 

 florescence loosely paniculate. 



F. paniculata, Torr. Stem 2 or 3 feet high : cauline leaves linear, opposite (about 3 

 pairs) : Hewers in a loose and ample panicle, slendei'-pedicelled : sepals ovate, barely half 

 the length of the whitish corolla : lobes of the latter oblong, obtuse, 2 or 3 lines long, 

 bearing a plane and roundish discolored gland about the middle, which is lightly fringed 

 round the border, its base confluent with a pair of coronal crests, which are adnate down 

 the lobe, bilamellate and strongly ciliate fimbriate above, tapering and tubular below : 

 filaments distinct to the base : style slender-subulate : stigma very small. — Pacif. 11. Rep. 

 iv. 126. — N. Arizona, sand bluffs at Inscription Rock in the Zufii country, Bigdow. Habit 

 of the two following species. What was described as a pair of glands rather belongs to the 

 crown. 



•j— -)— Capsule compressed parallel with the ilat or flattish valves: seeds as far as known flat, 

 smooth, and acute-margined. 



++ Inflorescence ample and cffusely paniculate; the pedicels longer than the flowers: corolla white 

 or yellowish with scattered dark dots, <if rather tirm texture and enduring ; the lobes acuminate 

 or nuicronate, longer than the ovate-lanceolate sepals. 



P. Parryi, Torr. Stem stout, 2 or 3 feet high, including the large and very compound 

 jiyramidal or corymbose panicle : leaves in pairs or occasionally in threes, lanceolate, or 

 the radical oblong, 3-nerved, 3 or 4 inches long ; the upper becoming much shorter, often 

 ovate-lanceolate, and soon reduced to small bracts : lobes of the white corolla ovate, be- 

 coming oblong, half inch long, bearing a large and lunate-obcordate conspicuously 

 fringed gland about on the middle, the base naked and destitute of a crown : some very 

 minute setcC at the base of the filaments : style distinct, but only one fourth the length of 

 the ovary: stigma small. — Bot. Mex. Bound. 156, & Pacif. K. Rep. iv. 126; Gray, Bot. 

 Calif, i. 484. Southern and eastern part of San Diego Co., California, to the borders of 

 Arizf)na, Coulter, Pain/, Palmer. 

 F. albomarginata, "Watson. Stem more slender, 1 to 3 feet high, including the 

 ample and very compound broad cymose panicle : leaves in fours and sometimes opposite, 

 linear, or the lower and radical oblanceolate, and the uppermost reduced to subulate bracts 

 subtending the long branches of the panicle : lobes of the greenish-yellow corolla ovate, 

 becoming oblong, cuspidate-acuminate, 3 or 4 lines long, twice the length of the sepals, 

 bearing the obcordate moderately villous-fringed gland about on its middle, this decurrent 

 into a longitudinally adnate crown with fringed free margins and a somewhat hooded base : 

 style slender : stigma small. — Bot. King, 1. c. ; Gray, Bot. Calif. I. c. — S. Utah and S. Ne- 

 vada, Palmer, Miss Searls, Parry. Leaves with conspicuous silvery-white and commonly 

 undulate border. 



•H- -H- Inflorescence a virgate interrupted thyrsus of 3 to 5 pairs of sessile (or the lower short- 

 peduncled) dense cymes, forming a series of" glomerate clusters: pedicels very short: leaves nar- 

 row and gramineous, mereh' opposite; the cauline only 3 to 5 pairs: corolla lavender-blue, of 

 thin texture: the lobes ovafe or oblong becoming narrower, 3 or 4 lines long, rather longer than 

 the subulate-lanceolate sepals; the fringed gland elongated, extending froni the base to near the 

 middle, saccate and with a longer and coarser fringe at base : crown staniineal, consisting of a 

 conspicuously laciniately parted or nearly entire scale Ijetween the filaments: style slender, 

 twice the length of the ovary : stigma entire : capsule flat, few-seeded. 



F. nitida, Benth. Completely glabrous, a foot or more high, slender: leaves linear- 

 lanceolate (2 to 4 lines wide, the upper 2, and the radical G or 8, inches long), those 

 subtending the upper flower-clusters reduced to small bracts : corolla sometimes greenish- 

 spotted ; the lobes barely acute, bearing an elongated oblong obtuse gland : thin scales 

 between the filaments ovate or oblong-linear, entire or sparingly laciniate, longer than the 

 ovary. — PI. Hartw. 322 ; Torr. Pacif. R. Rep. iv. 126 ; Gray, Bot. Calif. 1. c. —Foothills of 

 the Sierra Nevada, California, to the Dalles in Oregon. 



F. albicaulis, Dougl. Very minutely pruinose-puberulent : sepals rather longer and 

 narrower: condlalobes ovate-lanceolate and acuminate; the gland oblong-linear: scales 

 between the filaments more or less dissected into setiform processes : otherwise as the pre- 

 ceding. — Griscb. 1. c, & Hook. Fl. ii. 67, t. 151. — Interior of Oregon and Idaho, on the
