pedicelled to sessile in upper axils to form a several- to many-flowered leafy-bracted 

 raceme; calyx nearly regular, the tube to 7 mm. long and the slightly irregular 

 linear-subulate lobes about as long; corolla violet-color, cylindrical-funnelform, 

 nearly closed in anthesis, 2-2.5 cm. long, the short lobes acutish; lobes of the plaits 

 triangular, 2-cleft, acute, about half as long as the corolla lobes. Dasystephana

8. Gentiana Saponaria L. Bottle-gentian, soapwort-gentian. 



Perennial with a stout caudex and coarse roots, to 8 dm. tall, the stem glabrous 

 or sometimes slightly puberulent in lines; leaves narrowly elliptic to lanceolate, 

 obtuse to acute or occasionally shortly acuminate, abruptly narrowed at base, 

 ciliate, to 1 dm. long; involucre of 2 to 4 leaves, the outer to 6 cm. long and 2 cm. 

 wide; calyx lobes firm, oblong to oblanceolate or sometimes lanceolate, ascending, 

 to 12 mm. long; corolla blue or whitish, cylindric-oblanceolate, 3-5 cm. long, 

 1-1.5 cm. in diameter at the slightly open summit, the rounded to subacute lobes 

 erect and only slightly longer than the appendages.

9. Gentiana affinis Griseb. ex Hook. 



Cespitose perennial from rather thick fleshy roots, without rhizomes; stems 1 to 

 several, erect to decumbent at the base, 1.5-8 dm. tall, minutely puberulent in lines 

 below the slightly decurrent leaf bases; leaves in 8 to 15 pairs, the lowermost 

 usually reduced to bladeless connate sheathing bases; middle cauline blades nar- 

 rowly lanceolate to oblong or oblong-oblanceolate to broadly lanceolate or elliptic- 

 ovate, 2-5 cm. long, 5-20 (-25) mm. broad, usually very finely glandular-ciliolate 

 (at least near their bases); floral leaves similar to the cauline ones or shorter and 

 broader; flowers 5-merous, few, closely crowded, often arising from the top 2 or 

 3 nodes only or the upper 3 to 5 nodes all floriferous; peduncles 3-25 mm. long, 

 bracteate at the summit; bracteoles foliaceous to somewhat scarious, linear to 

 ovate; calyx tube 3-9 mm. long, tubular-funnelform, greenish- to bluish- or 

 purplish-tinged, with an inner membranous lining projecting above the bases, of 

 the lobes and toothed inside them; calyx lobes usually unequal, from ovate to 

 linear and from longer than the tube to reduced to mere teeth or lacking entirely, 

 the tube then nearly entire to erose and from nearly truncate to oblique or deeply 

 parted once or twice; corolla tubular-funnelform, (2-)2.5-4(-4.5) cm. long, deep- 

 blue but usually variously mottled or streaked with green; corolla lobes (3-)4-6(-7) 

 mm. long, oblong-ovate to ovate, rounded to acute or abruptly pointed, the plaits 

 of the sinuses one half to three fourths the length of the lobes and usually laciniately 

 deeply cleft into 2 to 5 narrow segments (entire); stamens slightly shorter than the 

 corolla tube; filaments adnate to near midlength of the corolla, the adnate portion 

 broadly wing-margined; anthers 2.5-4 mm. long; ovary long-stipitate; style short, 

 cleft above, the stigmatic surfaces oblong-oval; seeds flattened and wing-margined, 

 very finely reticulate. G. Parryi Engelm., Dasystephana Parryi (Engelm.) Rydb., 

 D. interntpta (Greene) Rydb.

 and about lakes, and wooded slopes, in N.M. (widespread in mts.) and Ariz. 

 (Apache, Navajo, Coconino, Gila and Greenlee cos.), July-Oct.; Sask. to B.C., 

 s. to N.M., Ariz, and Calif.
