 Oregon (Menzles, E. Hall) to Mendocino Co., California, Bolander. 

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

 few-several-liowered : leaves from ovate to oblong-laneeolate (1^ to 3 inches long), indis- 

 tinctly 3-7-nervcd : calyx-lobes unequal, lanceolate to ovate-oblong : corolla 1 J 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. — Hook. Fl. t. 145 ; Gray, Bot. Calif., excl. var. — W. Oregon to Brit. Columbia. 



= = Corolla (blue or bluish) funnelform. with ovate lobes not narrowed at base; the plaits 

 extended into cons])ieuons laciniatc-toothcd or cleft appenda.'^'es, Avhicli sometimes almost equal 

 the lobes : margins of the leaves seabrous : seeds sun'ounded by a distinct and I'ather broad wing, 

 ovate or oblong. 



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

 more slender and ascending: leaves ovate, sometimes ovate-oblong (1 to li inclies 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. — Engelm. in herb. G. ajftnis, var. 

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

 (Nevius, &c.) and W. California. Foliage and corolla somewhat as in G. cali/cosa, but the 

 smaller forms nearly approaching G. affinis. 



G. afKnis, Griseb. Stems clustered, a span to a foot high, mostly ascending : leaves 

 from oblong or lanceolate to linear : flowers from numerous and thyrsoid-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, the shorter sometimes minute : 

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

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

 1. c, excl. var. — Rocky Mountains from New Mexico and Colorado, and from the Sierra 

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



H— .}— Upper Mississippi-valley species : flowers almost sessile, 2-braeteate under the calyx : 

 corolla open-fimnelform with consjiieuously spreading lobes: anthers merely connivent, soon 

 separate : seeds conspicuoush- winged, oblong, all attached at or near the sutures. 



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

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

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

 oblong) to lanceolate-linear, an inch 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, U to 2 inches long; the ovate lobes (a fom-th to even half inch long) widely spread- 

 ing in anthesis, twice the length of the 2-cleft and sometimes laciniate-toothed appendages. 

 — Fl. i. 176 (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. 

 ^_ ^_ .^ Atlantic U. S. species (one or two crossing the Mississippi): seeds covering the whole 



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

 -H- Corolla campanulate-funnelform, with the sliort lobes little if at all spreading in anthesis: an- 

 thers cohering in a rini^ or short tulje: stem usnally several-flowered : flowers sessile or very 

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

 — Calyx-lobes and bracts ciliolate-seabrous: seeds winged or appendaged. 

 G. EUiottii, Chapm. Puberulcnt-roughish in the manner of the preceding, a span to a 

 foot or more' Inub, slender : leaves from lanceolate to ovatedanceolate, 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 : calyx-lobes lanceolate or broader, foliaceous, twice or 

 thrice the length of the tube, ciliolate-seabrous: corolla bright blue, 1 to li inches long; 

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

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

 or oblongdanceolate in outline. — Fl. 350, specially the var. parvifolia, " G. Catesbm, Ell. not 

 Walt." according to Chapman. Perhaps an extreme form of the next ; but the Florida 

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

 G. Saponaria, L. Stem a foot or two high, smooth, or somewhat scabrous above : leaves 

 from ovate-lanceolate or oblong to broadly lanceolate, 2 or 3 inches long, more or less nar-
