482 GENTIANACEiE. Gentiana. 



"Wet ground, in the higher regions of the Sierra Nevada : Soda Springs of the Tuolumne, at 

 8,600 feet (a pygmy form, only 2 to 5 inches high, with leaves merely 4 or 5 lines long and crowded 

 towards the base), to Mariposa Co. above the Yosemite (much larger, a span high or more), Bo- 

 lander. Both of the variety, which accords with the Scandinavian plant, except in the entireness 

 of the corolla lobes, which also occurs in European specimens. The larger form, G. dctonsa, var. 

 barbata, Froelich and Grisebach, which is common eastward of the Kocky Mountains, where it too 

 closely approaches G. crinita (the common Fringed Gentian of the Atlantic States), is unknown in 

 California and Oregon. It is singular that, while only entire petals are known of this species in 

 California, the G. simplex, described with entire petals, has them sparingly fringed in most of the 

 specimens now known. 



§ 2. Plaited folds at the sinuses of the short-funnelform or campanulate 5-lobed 

 (in ours blue or bluish) corolla: anthers erect and fixed: root perennial. — 

 Pneumonanthe. 



* Plaits extended between the lobes into consp>icuous cleft or lacerate appendages. 



+- Low, with decumbent one-flowered stems : leaves with co?ispicuously connate-sheathing 

 base, the uppermost becoming bracts to the flotver. 



4. Gr. Newberryi, Gray. Dwarf (2 to 4 inches high) : flowering stems 1 to 4, 

 ascending from around a short central axis -which bears a rosette of ohovate or 

 spatulate leaves, of about an inch in length : cauline leaves 2 to 4 pairs (half an 

 inch long) ; the lowest obovate, the uppermost oblanceolate : calyx-lobes oblong or 

 lanceolate, nearly as long as the tube : corolla broadly funnelform (over an inch 

 long), pale blue, within white, and greenish-dotted ; its lobes ovate, mucronate, 

 longer than the slender-subulate tips of the 2-cleft or laciniate interposed appen- 

 dages : seeds oval, broadly winged. — Proc. Am. Acad. xi. 84. 67. calycosaif), Gray in 

 Pacif. E. Eep. vi. 86, not of Grisebach. 



Sierra Nevada, at 5,000 to 8,000 feet; Crater Pass in Oregon, lat. 44° {Newberry), Lassen's 

 Peak (Brewer), and Mariposa Co. south of the Yosemite, Bolander. Somewhat related to G. 

 fricjida, which inhabits the alpine region of the Kocky Mountains. 



5. Gr. setigera, Gray. Stems stout, but diffusely spreading from a thick caudex, 

 a foot or less long, bearing 7 to 10 pairs of thick very obtuse leaves : lower leaves 

 round-oval ; upper oblong ; two uppermost pairs involucrate around the flower (all 

 an inch long, or the lower shorter) : calyx-lobes oval, about the length of the tube : 

 corolla oblong-campanulate, apparently with dull purplish tube and the ovate lobes 

 blue : appendages in the sinuses small and short, but extended into 2 or 3 capillary 

 bristles which almost equal the lobes. — Proc. Am. Acad. xi. 84. 



Red Mountain, Mendocino Co., in damp soil, Bolander. Corolla an inch and a half long, 

 rather broad ; the lobes nearly half an inch long. Sheaths of the leaves mostly a quarter of an 

 inch long. Forming seeds orbicular and winged. 



-i — f- Mostly erect and taller, 1 - several-flowered, leafy : leaves not conspicuously 

 connate-sheathing at base, except the lower p>airs. 



6. Gr. calycosa, Grisebach. A span to a foot in height : leaves ovate (an inch 

 to half an inch long) ; the lower decreasing in size, the one or two uppermost pairs 

 involucrate around the one to three sessile flowers : calyx-lobes ovate or ovate-lance- 

 olate, equalling or rather shorter than the short tube : corolla oblong-campanulate, 

 blue (over an inch long) ; appendages in the sinuses laciniate, shorter than the 

 broadly ovate lobes : seeds lanceolate, wingless. — Gent. 292, & in Hook. PL ii. 58, 

 t. 146. 



Sierra Nevada at 8,800 feet in Placer Co. (Brewer); Calaveras Co., near Murphy's (Lemmon) ; 

 also collected at some unknown station by Bridges. Occurs in the northern Kocky Mountains 

 and those of the interior of Oregon. Rarely 2 or 3 flowers from the axils. 



G. Parryi, Engelm., of the Colorado Rocky Mountains, collected by Watson in the northeast- 

 ern part of Nevada, differs principally in the much smaller calyx-lobes, and the leaves are some- 

 times narrower. 



7. Gr. affinis, Grisebach. A foot or two or sometimes only a span high : leaves 

 from ovate-oblong to linear-lanceolate (an inch or so in length), the uppermost
