Gentiana. GENTIAN ACEiE. 121 



cauline leaves much smaller, connate-sheathing ; the lowest obovate, the uppermost lanceo- 

 late : calyx-lobes lanceolate or oblong, nearly the length of the oblong-campanulate tube : 

 corolla broadly f unnelform, inch anrl a half long, pale blue, white within, greenish dotted ; 

 its lobes ovate, mucronate ; the interposed appendages 2-cleft or laciniate, subulate-tipped : 

 seeds round-oval, smooth, broadly Ayinged. — Proc. Am. Acad. xi. 84, & Bot. Calif, i. 482. 

 G. calycosa ? Gray in Pacif. E. Rep. vi. 86. — Sierra Nevada, California, in or near the 

 alpine region, from Mariposa Co. north to S. Oregon, Newberry, Brewer, &c. 



++ ++ Low: stems several from the same caudex : cauline leaves G to 16 pair<, more or less con- 

 nate or even sheathing at base; the uppermost involucrate around the sessile terminal flower or 

 3-5-flowered cluster: corolla campanulate-funnelform, blue, 1£ to 1J inches long; the lobes 

 broadly ovate, and the appendages at the sinuses 2-cleft or lacerate. 



G. setigera, Gray. Stems stout, about a foot long, decumbent : leaves thick and pale, 

 oval or the upper oblong, very obtuse, an inch or less long ; the pairs all with a connate- 

 sheathing base, the two uppermost involucrate around and covering the base of the soli- 

 tary flower : calyx-lobes oval, about the length of the tube : corolla almost campanulate ; 

 the appendages of the plaits small and short, produced into 2 or 3 capillary bristles which 

 nearly equal the lobes : forming seeds orbicular, winged. — Proc. Am. Acad. xi. 84, & Bot. 

 Calif. 1. c. — California, on Red Mountain, Mendocino Co., in damp soil, Bolander. 



G. calycosa, Griseb. Stems erect, a span to a foot high : leaves ovate (6 to 15 lines 

 long), commonly equalling or exceeding the internodes ; the lowest pairs usually smaller 

 and with connate-sheathing base, the upper hardly so ; the involucrate uppermost leaves 

 somewhat exceeding the calyx of the commonly solitary flower: calyx-lobes ovate or 

 oblong, or even subcordate, about the length of the turbinate tube : corolla oblong-funnel- 

 form, its appendages in the sinuses triangular-subulate, laciniate, or 2-cleft at the tip, 

 shorter than the broadly ovate lobes : seeds lanceolate, acuminate, wingless. — Gent. 1. c. & 

 Hook. Fl. t. 146 ; Gray, Bot. Calif. 1. c. — Varies with stems only 2 to 4 inches high, and 

 small leaves crowded (var. stricta, Griseb. 1. c.) ; also with taller and more slender stem 

 2-3-flowered, occasionally with one or two axilliary conspicuously pedunculate flowers 

 subtended by a pair of smaller bracts. — California (Sierra Nevada, Bridges, Brewer, Lem- 

 mon), Oregon (Tolmie), and Rocky Mountains, lat. 42°-49°, Porter, Lt/all. 



G. Parryi, Engelm. A span or more high : leaves glaucescent, thiekish, ovate, varying 

 to oblong-lanceolate, three-fourths to inch and a half long, most of the pairs with some- 

 what sheathing base; the upper 2 or 3 involucrating the 1 to 5 flowers, concealing the 

 calyx and sometimes almost equalling the (bright purple-blue) corolla: lobes of the calyx 

 short-linear, small, moderately or much shorter than the campanulate (sometimes spa- 

 thaceous-clef t) tube : appendages at the sinuses of the corolla narrow, deeply 2-cleft, little 

 shorter than the obovate lobes : seeds lanceolate, wingles s, obtuse or less acute than in 

 G. calycosa, which the broad-leaved forms of this much resemble. — Trans. Acad. St. Louis, 

 ii. 218, t. 10; Watson, Bot. King, 279. G. calycosa, var. Parryi, Herder, 1. c. 178. — Alpine 

 and subalpine regions in the Rocky Mountains, New Mexico, Colorado, Utah, and N. E. 

 Nevada, Parry, &c. 



++++++ Stems either tall or low, many-leaved : flowers not involucrate: style manifest. 



= Corolla (blue or bluish) oblong-campanulate, with broadly ovate lobes more or less narrowed at 

 base, and the intervening plaits or lobes entire : calyx-lobes usually from ovate to lanceolate, 

 equalling or longer than the tube : seeds wingless. 



G. platypetala, Griseb. Stems a span high, ascending, densely leafy above, bearing 

 a single sessile flower: leaves ovate-roundish, recurved-spreading : lobes of the 5-parted 

 calyx ovate, acute : campanulate tube of the blue corolla twice the length of the calyx ; 

 its short lobes somewhat reniform, mucronate (2 lines long and 3 wide), double the length 

 of the triangular acute and entire plaits. — Gent. 191, & in Hook. 1. c. ; DC. 1. c. — " Sitka, 

 Kotzebue." The char, from Grisebach. Referred to G. calycusa by Herder, and it must 

 resemble its smaller form ; but the sinus-plaits are said to be entire. 



G. Menziesii, Griseb. 1. n- Stems » foot or less high, slender: leaves from narrowly 

 oblong to lanceolate (inch and a half or less long), somewhat 3-nerved : flowers one or two, 

 short peduncled or sessile : calyx according to Grisebach spathaceous and the lobes obso- 

 lete, in our specimens with oblong-lanceolate foliaceous lobes (5 lines long) equalling the 

 turbinate-oblong tube : corolla an inch long ; its lobes 3 lines long and wide ; its plaits 

 truncate and obscurely 2-3-crenate : seeds ovate-lanceolate or oblong, barely acute or both
