GENTIANA

connivent at the apex. N. Amer. Not B.M. 1531 or 1551. 

 Var. intermedia, Griseb. ( G. intermedia, Sims, not L. B. 

 C..S:21HI, may 111- a hybrid between this and (?.^«(JrcH'sii. 

 It resiMiiliIrs (1. nchroleuca in having calyx lobes of 

 unequal leni;ths, but as long as or longer than the calyx 

 tube, and free anthers: it resembles G. Andreirsii in the 

 tinge of purplish blue. B.M. 2303. Var. incarnita.Griseb. 

 ((?. ineaniAta, Sims). B. M. 1856 from Carolina i.s not 

 cult. These forms are not considered worthy of varietal 

 rank in Gray's Syn. Fl. 



9. trigida, Haenk. Lvs. spatulate-Iinear, obtuse: fls. 

 1 or 2 at the top, sometimes a few in the upper axils; 

 calyx not laterally cut, and half as long as the corolla or 

 more; calyx teeth lanceolate, a little longer than the 

 calyx tube; corolla club-shaped, plaits not cut. Car- 

 pathian Mts.; also N. Araer. — This is the true type of 

 (f. frigida, which is not in cultivation, but is inserted to 

 make clear the differences between G. algida of Pallas 

 and of Steven. 



10. ilglda, Pall., not Stev. (G. frigida, var. dlgida, 

 Griseb.). Lvs. lanceolate-linear: fls. 2-5 at the top and 

 distinctly pedicelled ; calyx laterally cut and one-third the 

 length of the corolla ; calyx teeth linear - lanceolate, 

 hardly as long as the calyx tube and sometimes only 

 half as long; corolla between club- and bell-shaped; 

 plaits cut with a few crenate teeth. Altai Mts., E. Si- 

 beria, N. Am. Gn. 17, p. .343, same as Gn. 27, p. 89; 48, 

 p. 146, and N. 2:60, Pig. 93. -This grows 4-5 in. high, 

 has numerous stems and fls. nearly 2K in. long, whit- 

 ish, with blue spots in longitudinal lines. The writer 

 has not seen Gt. 1006. 



11. g61ida, M. Bieb. {G. dlgida, Stev., not Pall.). 

 Lvs. ovate-lanceolate. 3-nerved: fls. few and terminal, 

 or many in the upper axils, peduncled; calyx teeth 

 linear-oblong, acute, nearly as long as the calyx tube or 

 shorter than it; corolla rather bell-shaped, yellowish 

 white, its lobes broadly ovate, twice as long as the calyx 

 and twice as long as the lacerated plaits. June, July. 

 Caucasus. Not P.M. 7:5, which is G. sepfemfida,v&r. 

 cordi folia.— "Light, deep, cool soil and full sunlight." 

 Correvon. 



12. campistris, Linn. Annual : fls. dark purplish 

 blue; calyx 4-cut; corolla nearly bowLshaped, crowned; 

 anthers free ; style none. 



13. Moorcrofti4na, Wall. Annual, 4-10 in. high: fis. 

 pale blue; calyx 5-cut; corolla funnel-shaped. Himal. 

 B.M. 6727, where fls. are shown as pale purple. 



14. crinlta, FrcEl. Fig. 897. Fringed Gentian. Bien- 

 nial: erect, branched, 1-2 ft. high: lvs. lanceolate or 

 ovate-lanceolate, acutish, from a rounded or subeordate 

 partly clasping base : corolla lobes wedge-obovate : 

 seeds roughened by scales or needle-like projections. 

 Moist woods and meadows. N. Amer. B.M. 2031. D.275. 

 G.W.F. 19. Mn. 4:161. B.B. 2:613.-The ribs of the 

 calyx (made by the decurrent lobes) are one of the mi- 

 nor beauties of this plant, and are probably more pro- 

 nounced than in the other Fringed Gentians here de- 

 scribed. 



15. cilid,ta, Linn. Perennial: stem flexuose, scarcely 

 branched: lvs. linear, obtuse: corolla lobes obovate-ob- 

 long: seedssmooth. Dry limestone soils. En. Not B.M. 

 <i39, which is G. serraia. — Hardly 3 per cent of Correvon's 

 seedlings have flowered. He recommends a heavy, com- 

 pact soil which is almost clayey, and full sunlight. 



16. serrita, Gunn. {G. barbAta, Proel. G. detdnsa, 

 Griseb. G. di'tdnfta, var. barbdta, Griseb.). Annual: 

 stem erect, branching, 3-18 in. high: lvs. linear orlance- 

 liuear: coroUalobes oblong or spatulate-obovate, fringed 

 around the apex and sides or sometimes either part 

 nearly bare. Wet lands, Ural and Altai Mts., Caucasus, 

 N.Amer. B.B. 2:614. B.M. 639 erroneously as G. ci/iafa. 

 — No plants appear to be advertised as G. serrata. G. 

 barbata is a trade name abroad. 



17. qulnqueldlia, Linn. (G. quinquefUra, Hill, La- 

 marck and others). Annual: height 1-2 ft., the larger 

 plants branched : lvs. .3-7-nerved: inflorescence thyr- 

 soid-paniculate : clusters 3-5-fld. : fls. bright blue; 

 «alyx one-fifth or one-fourth as long as the narrowly 

 funnel-shaped corolla. N. Araer. Probably the form 

 in cult, is var. occidentilis, Gray. Height 2-3 ft., 



paniculately much branched : inflorescence more open : 

 calyx half the length of the broader corolla. B.B. 2:615. 

 B.M. 3496. -Very pretty. 



18. FroBlichii, Jan. Stems short, almo.st tufted: fls. 

 blue, solitary, peduncled, nearly as long as the stem: 

 corolla not spotted. Very rare in Alps, limestone rocks. 

 — Easily grown on rockwork in compost of equal parts 

 of sphagnum, heath soil and vegetable mold. Half-ex- 

 posure to sunlight. 



19. asclepiad^a, Linn. Stem strict: calyx teeth very 

 short : fls. in spike-like racemes, dark blue ; corolla 

 club-shaped; calyx one-third as long as the corolla: seeds 

 not winged. July-Sep. S. Eu., Caucasus. B.M. 1078. 

 Gn. 48, p. 143, and 54, p. 39. — The white-fld. form is excel- 

 lent. Shade or half-shade, and moist, deep soil rich in 

 humus. 



20. Fneumon&nthe, Linn. Stem erect: fls. dark blue 

 in a cyme-like raceme (the top fls. opening first); co- 

 rolla club-shaped; lobes ovate, acute, mucronate, much 

 longer than the appendages. Aug. -Oct. Mountain 

 marshes, Eu., N. Asia. Var. guttata. Sims, is dotted 

 white. B.M. 1101.— "Requires a cool, deep, spongy soil, 

 rich in humus. Dislikes lime, and prefers sandy soil. 

 Does remarkably well when planted on margins of ponds 

 or brooks. Prop, by seed or division." Correvon. 



21. Sapon&ria, Linn. {G. C(itesba>i,Vf alt., not And.). 

 Barrel or Soapwort Gentian. Stem ascending: fls. 

 light blue, club-shaped; caljTC lobes linear or oblong, 

 mostly as long as the calyx tube ; corolla lobes short, 





aed Gentian- Gentiana crinita (X K). 



broad, roundish, erect, little, and often not at all longer 

 than the 2-cleft and many-toothed intervening appen- 

 dages. N.Amer. B.M. 103"9.-(Hookerisprobably wrong 

 in referringthis picture toG. Andrewsii, though the calyx 

 lobes in the plate are not narrow enough. ) Cult, like 20. 

 22. Andrewsii, Griseb. (O. CAtesbai, And., nofWM.) 

 Closed, Blind or Bottle Gentian. Fig. 898. Stem 

 ascending: fls. purplish blue; calyx lobes lanceolate to
