G. Wislizeni. Bngelm A foot or less high, with the habit and many.flowered thyrsoid- 

 pamculate inflorescence of Gqmn^uejiora, but smaller in all its parts : leaves from lanceo- 

 ate to ovate (an mch or less long), with obtuse or subcordate base : calyx barely ha!f the 

 length of the tube of the corolla; its scarious tube (li lines long) split down one side in 

 age some imes dejected, much longer than the 5 unequal linear herbaceous teeth • corolla 

 nearly salverform, pale purplish, 4 or 5 hues long ; its lobes oblong-ovate, copiously fringed 

 above the base: capsule sessile: seeds globose. — Trans. Acad. St. Louis u 215 t 7 —

 G. aurea, L. Leaves ovate, 5-7-nerved ; the margins and those of the spatulate-lanceolate 

 calyx-lobes smooth : corolla yellow, violet, or commonly white, 4 lines long, little surpass-

G. propinqua, Richards. Stem slender, 2 to 7 inches high, mostly branched from the 

 base: leaves from oblong to lanceolate and the lowest spatulate, obscurely 3-nerved, the 

 edges and those of the calyx smooth: flowers chiefly 4.merous and rather slender-pedi- 

 celled: lobes of the calyx unequal; two of them ovate or oblong, the others linear-lanceo- 

 late, the larger rather shorter than the tube of the corolla : the latter bluish, narrow, 4 to 

 y Imes long, its lobes ovate or in age lanceolate, sometimes erose-denticulate. - App

Var. densiflora, Griseb, 1. c, in alpine swamps of the Rocky Mountains (Dmm- 

 mond), a more condensed and leafy plant, occurring with the ordinary form, is said to differ 

 from the preceding species only in the inequality of the calyx-lobes. 

 G. arctophila, Griseb. Stem an inch to a span high : leaves ovate-oblong or the low- 

 est obovate ; the edges and especially those of the calyx-lobes scabrous : corolla 7 to 10 

 Imes long ; the round-ovate lobes more acuminate-cuspidate : otherwise very like large- 

 flowered G. propinqua (to which Herder refers it). — Gent. 251, & in Hook. Fl. ii. 61 t. 149

= = Taller and leafy : calyx 5-cleft : capsule slender-stipitate. 

 G. quinqueflora, Lam. A foo't or two high ; the larger plants branching : leaves ovate- 

 lanceolate, with subcordate partly clasping base, 3-7-nerved, the upper acute or cuspi- 

 date-acuminate : inflorescence thyrsoid-paniculate ; the clusters 3-5-flowered: calyx one 

 fifth or fourth the length of the narrow funnelform bright blue corolla ; its lobes linear- 

 subulate: corolla half to three fourths inch long; its lobes ovate-triangular, short. — Diet,

Var. occidentalis, Gray. Sometimes 2 or 3 feet high and paniculately much 

 branched : inflorescence more open : calyx-lobes more foliaceous, linear or lanceolate, un- 

 equal, reaching to the middle of the broader funnelform corolla. — Man. ed. 1, 359, ed. 5, 387.

Var. parviflora, Raf., collected in Virginia, Kentucky, &c. (Griseb. in DC. 1. c. 100), 

 is a depauperate and small-flowered state of the preceding variety, and is G. amareUoides
