Genus 4. 



GENTIAN FAMILY. 



2. Gentiana crinita Froel. Fringed Gen- 

 tian. Fig. 3348. 



Gentiana crinita Froel. Gen. 112. 1796. 



Annual or biennial; stem leafy, usually branch- 

 ed, l -3i high, the branches erect, somewhat 

 4-angled. Basal and lower leaves obovate, ob- 

 tuse, the upper lanceolate or oblong-lanceolate, 

 1 '-2' long, acute or acuminate at the apex, sessile 

 by a rounded or subcordate base ; flowers mostly 

 4-parted, several or numerous, about 2' high, 

 solitary at the ends of the usually elongated 

 peduncles ; calyx-lobes lanceolate, acuminate, un- 

 equal, their midribs decurrent on the angles of 

 the tube ; corolla bright blue, rarely white, nar- 

 rowly campanulate, its lobes obovate, rounded, 

 conspicuously fringed all around their summits, 

 scarcely fringed on the sides, spreading when 

 mature; capsule spindle-shaped, stipitate; seeds 

 scaly-hispid. 



In moist woods and meadows, Quebec to Ontario, 

 Minnesota, south to Georgia and Iowa. Sept.-Oct. 



3. Gentiana procera Holm. Smaller 

 Fringed Gentian. Fig. 3349. 



Gentiana procera Holm, Ottawa Nat. 15: 11. 1901. 



Annual ; similar to the preceding species but 

 smaller; stem simple, or little branched, 3'-i8' 

 high. Basal and lower leaves spatulate, obtuse, 

 the upper linear or linear-lanceolate, 1-2J' long, 

 z"4" wide ; flowers 1-6, solitary at the ends of 

 elongated erect peduncles, mostly 4-parted, about 

 lh' high; calyx-lobes lanceolate, acuminate, their 

 midribs decurrent on the tube ; corolla narrowly 

 campanulate, bright blue, its lobes spatulate- 

 oblong, strongly fringed on both sides, entire or 

 somewhat fimbriate or toothed around the apex ; 

 capsule short-stipitate ; seeds scaly-hispid. 



In wet places, New York and Ontario to Minne- 

 sota, South Dakota and Manitoba. July-Sept. Pre- 

 viously confused with G. dctonsa Rottb. and with G. 

 serrata Gunner, Old World species. Northwestern 

 and Rocky Mountain plants formerly referred to 

 this species prove to be distinct from it. 



Gentiana nesophila Holm, of Anticosti, differs in 

 merely denticulate corolla-lobes. 



4. Gentiana acuta Michx. Northern Gentian. 

 Fig- 33SO. 



Gentiana acuta Michx. Fl. Bor. Am. 1: 177. 1803. 

 Gentiana Amarella var. acuta Herder, Act. Hort. Petrop. 

 1 : 428. 1872. 



Annual; stem leafy, slightly wing-angled, simple or 

 branched, 6'-2o' high. Basal and lower leaves spatu- 

 late or obovate, obtuse, the upper lanceolate, acuminate 

 or acute at the apex, rounded or subcordate at the 

 base, sessile, or somewhat clasping, -2' long; flowers 

 numerous, racemose-spicate, 5"-8" high, the pedicels 

 2"-6" long, leafy-bracted at the base; calyx deeply 

 5-parted (rarely 4-parted), its lobes lanceolate; corolla 

 tubular-campanulate, 5-lobed (rarely 4-lobed), blue, its 

 lobes lanceolate, acute, each with a fimbriate crown at 

 the base; capsule sessile. 



In moist or wet places, Labrador to Alaska. Maine, 

 Minnesota, south in the Rocky Mountains to Arizona and 

 Mexico. Also in Europe and Asia. Closely resembles the 

 Old World G. A marella. Felwort. Bastard-gentian. Bald- 

 money. Summer.
