ends obtuse. — G. sceptrum, var. huiniUs, Engelm. ; Gray, Bot. Calif, i. 483. — Bogs, W. 

 Oregon (Mcnzies, 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-tlovvered : leaves from ovate to oblong-lanceolate (1^ to 3 inches long), indis- 

 tinctly 3-7-nervcd : 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. — Hook. Fl. t. 145 ; Gray, Bot. Calif., excl. var. — W. Oregon to Brit. Columbia. 



= =r. Corolla (blue or blui.sh) funiielfonu, with ovate lobes not narrowed at base; the plaits 

 extended into conspicuous laciuiate-toothed or cleft appendages, which sometimes almost equal 

 the lobes : margins of the leaves scabrous : seeds surrounded by a distinct and rather 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 

 f unnelf orm, over an inch long ; its short lobes roundish. — Engelm. in herb. G. affinis, var. 

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

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

 smaller forms nearly aj)proaching 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 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 narrowly f nnnelform ; 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. — llocky ]\Iountains from New Mexico and Colorado, and from the Sierra 

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



-K- -f— Upper Mississippi-valley species: flowers almost sessile, 2-bracteate under the calyx: 

 corolla open-funnelform with consjjicuously spreading lobes: antiiers merely coiniivent, soon 

 separate: seeds conspicuously 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 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 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, 1^ to 2 inches long; the ovate lobes (a fourth to even half incii long) widely spread- 

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

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

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

 and Minnesota. 



•t^ -t— -i^ Atlantic U. S. species (one or two crossing the Mississippi): seeds covering the whole 



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

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

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

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

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

 G. EUiottii, Chapm. Puberulent-roughish in the manner of the i)receding, a span to a 

 foot or more high, 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 : calyx-lobes lanceolate or broader, foliaceous, twice or 

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

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

 cleft erose-dentate or somewliat fimbriate api)endages : seeds conspicuously winged, ovatc- 

 or oblong-lanceolate in outline. — Fl. 35G, specially the var. parvi/ulia, " G. Catesbcei, 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-
