 G. sceptrum, Griseb. 1- c. Stem erect, 2 to 4 feet high, simple or short-branched above, 

 few-several-flowered: leaves from ovate to oblong-lanceolate (l-J to 3 inches long), indis- 

 tinctly 3-7-nerved ; calyx-lobes unequal, lanceolate to ovate-oblong : corolla IJ to 2 inches 

 long, sometimes greenish-dotted; its lobes nearly 4 lines long and wide; its plaits truncate 

 or with barely rounded entire summit : seeds narrowly lanceolate and with scarious acu- 

 mination. — Ilook. Fl. t. 145 ; Gray, Bot. Calif., excl. var. — "W. Oregon to Brit. Columbia. 



= = Corolla (blue or bluish) funuelform. with ovate lobes not nan-owed at base; the plaits 

 extended into conspicuous laciniatc-toothed or cleft appcndii'^-cs, wliich sometimes abnost equal 

 the lobes ; margins of the leaves scabrous : seeds surrounded by a distinct and rather broad wing, 

 ovate or oblong. 



G. Oregana, Bngelm. Stems erect and rather stout, a foot or two high, sometimes 

 more slender and ascending: leaves ovate, sometimes ovate-oblong (1 to 1+ Indies long) : 

 flowers few at the summit, or occasionally several and racemose-scattered : bracts oblong or 

 ovate : calyx-lobes from oblong- to ovate-lanceolate, as long as the tube : corolla broadly 

 funnelform, over an inch long ; its short lobes roundish. — ^Engolm. in herb. G. affinis, var. 

 ovata, Gray, Bot. Calif, i. 483. — Brit. Columbia and W. Idaho (Lijall, Spalding) to Oregon 

 (Nevias, &c.) and W. California. Foliage and corolla somewhat as in G. calycosa, but the 

 smaller forms nearly approaching G. affinis. 

 "■G. affinis, Griseb. Stems clustered, a span to a foot high, mostly ascending: leaves 

 from oblong or lanceolate to linear : flowers from numerous and tbyrsoid-racemose to few 

 or rarely almost solitary : bracts lanceolate or linear : calyx-lobes linear or subulate, une- 

 qual and variable, the longest rarely equalling the tube, tlie shorter sometimes minute : 

 corolla an inch or less long, rather narrowly funnelform ; its lobes ovate, acutish or mu- 

 cronulate-pointed, spreading. — Gent. 1. c. & DC. L c. 114; Watson, Bot. King, 279; Gray,

 Nevada, California, to British Columbia, thence east to the Saskatchewan. 



•i^ -y- Upper Mississippi-valley species: flowers almost sessile, 2-bracteate under the calyx: 

 corolla open-funnelform witli couspicuously spreading lobes : anthers merely connivent, soon 

 separate : seeds conspicuously winged, oblong, all attached at or hear the sutures. 



G. puberula, Michx. About a foot high, mostly single-stemmed from the root, very 

 leafy, at least the upper part of the stem, with the margins and midrib of leaves and 

 sepals minutely puberulent-scabrous : leaves rigid, from oblong-lanceolate (or the lower 

 oblong) to lanceolate-linear, an incli or two long : flowers solitary or several and clustered : 

 calyx-lobes linear-lanceolate or subulate-linear, about the length of the tube : corolla bright 

 blue, 1^- to 2 inches long; the ovate lobes (a fourth to even half inch long) widely spread- 

 ing in anthesis, twice the length of the 2-('k'ft and sometimes laeiniate-toothed appendages. 

 — Fl. i. 170 (descr. not good as to corolla) ; Gray, Man. ed. 2, 347, ed. 5, 389. ( G. Saponaria, 

 var. puberula, ed. 1.) — Dry prairies and barrens, Ohio, Kentucky, and Kansas to Wisconsin 

 and Minnesota. ' 



-1— -I 1— Atlantic U. S. species (one or two crossing the Mississippi): seeds covering the whole 



parieties of the capsule : style manifest, in most conspicuous. 

 ++ Corolla (■ampanulate-funnelform, witli the short lobes little it at all spreading in anthesis: an- 

 thers cohering in a rini;- or short tube: stem usually several-flowered: flowers sessile or very 

 short-peduncled and 2-hracteate under the calyx, clustered at summit and often in upper axils. 

 = Calyx-lobes and bracts ciliolate-scabrous : seeds winged or appendaged. 

 G. EUiottii, Ghapm. Puberulent-roughish in the manner of the preceding, a span to a 

 foot or more higli, slender: leaves from lanceolate to ovate-lanceolate, or the lower ovate, 

 an inch or less long, the broadest subcordate: flowers 1 to 3 terminal, and sometimes also 

 in the axils, sessile, leafy-bracted : calyxdobes lanceolate or broader, foliaceous, twice or 

 thrice the length of the tube, ciliolate-scabrous : corolla briglit blue, 1 to 1-J- inches long ; 

 the broadly ovate obtuse lobes (3 lines long) hardlj' twice the length of the broad and 2- 

 cleft erose-dentate or somewhat fimbriate appendages : seeds conspicuously winged, ovate- 

 or oblong-lanceolate in outline. — Fl. 356, specially the var. parvifolia, " G. Catesbcei, EU. not 

 Walt." according to Cliapman. Perliaps an extreme form of the next ; but the Florida 

 plant appears to be quite distinct. — S. Carolina ? to Florida.
