8. vill6sa, Linn. (G. ochroleuca, Froel.). St. smooth 

 scending, simple or nearly so, slender, 6-18 in. tall: 

 Ivs. ovate-lanceolate and obovate: fls. in crowded 

 terminal, nearly sessile, leafy clusters, or sometimes 

 axillary; corolla yeUowish white or greenish, club- 

 shaped, connivent at the apex. E. N. Amer. Not 

 B.M. 1551. Var. intennedia, Griseb. (G. intermedia, 

 Sims, not L.B.C. 3:218), may be a hybrid between this 

 and G. Andrewsii. It resembles G. ochroleuca in having 

 calyx-lobes of unequal lengths, but as long as or longer 

 than the calyx-tube, and free anthers: it resembles 

 G. Andrewsii in the tinge of purplish blue. B.M. 2303. 

 Var. incamata, Griseb. (G. incarnala, Sims), B.M. 

 1856, from Carolina is not cult. These forms are not 

 considered worthy of varietal rank in Gray's Syn. Fl. 



9. frigida, Hsnke. Lvs. spatulate-Unear, 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. Amer. — This is the true type of 

 G. frigida, which is not in cult., but is inserted to make 

 clear the differences between G. aJgida of PaUas and of 

 Steven. 



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

 Griseb.). Lvs. lanceolate-hnear; 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 caly.x-tube and 

 sometimes only half as long; 

 corolla between club- and bell- 

 shaped; plaits cut with a few 

 crenate teeth. Altai Mts., E. 

 Siberia, N. Amer. Gn. 17, p. 

 343, same as Gn. 27, p. 89; 48, 

 p. 146. — This grows 4-5 in. 

 high, has numerous sts. and fls. 

 nearly 2}'2 in. long, whitish, 

 with blue spots in longitudinal 

 hues. 



11. gelida.Bieb. (G. 



dlgida, Stev., not 

 Pall.). Lvs. ovate- 

 lanceolate, 3-ncrved: 

 fls. few and terminal, 

 or many in the upper 

 axils, peduncle d; 

 calyx-teeth linear-ob- 

 long, 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. septemfida var. cordifolia. — 

 "Light, deep, cool soil and full sunlight." — Correvon. 



12. campestris, Linn. A low slender annual with 

 erect st. 2-6 in. tall: lvs. sessile, ovate-lanceolate, 3-5- 

 nerved: fls. dark purplish blue, short-podicelled, but in 

 various kinds of clusters; calyx 4-cut; corolla nearly 

 bowl-shaped, crowned; anthers free; style none. Eu. 



13. Moorcroftiana, Wall. A stiff annual 8-16 in. 

 high: fls. pale blue in nearly terminal cymes which are 

 racemosely clustered ; calyx 5-cut ; corolla funnel-shaped, 

 about 1 J^2 in. wide. Himalayas. B.M. 6727, where fls. 

 are shown as pale purple. 



14. crinita, Froel. Fig. 1625. Fringed Gentian. 

 Biennial or often annual: erect, branched, 1-2 ft. high: 

 lvs. lanceolate or ovate-lanceolate, acutish, from a 

 rounded or subcordate partly clasping base: coroUa-

lobes wedge-obovate : seeds roughened by scales or 

 needle-Uke projections. Moist woods and meadows. N. 

 Amer. B.M. 2031. Mn. 4:161. B.B. 2:613.— The ribs 

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

 the minor beauties of this plant, and are probably more 

 pronounced than in the other fringed gentians here 

 described. Almost impossible to grow in cult. 



15. ciliata, Linn. Perennial: st. flexuose, scarcely 

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

 oblong: seeds smooth. Dry limestone soils. Eu. Not 

 B.M. 639, which is G. serrata. — Hardly 3 per cent of 



. Correvon's seedlings have flowered. He recommends 

 a heavj', compact soil which is almost claj'ey, and full 

 sunlight. 



16. serrata, Gunner (G. barbata, Froel. G. detdnsa, 

 Griseb. G. detdnsa var. barhdta, Griseb.). Annual: 

 st. erect, branching, 3-18 in. high: lvs. linear or lance- 

 hnear: corolla-lobes oblong or spatulate-obovate, 

 fringed around the apex and sides or sometimes either 

 part nearly bare. Wet lands, Ural and Altai Mts., Cau- 

 casus, N.'Amer. B.B. 2:614. B.M. 6.39 (erroneously 

 as G. ciliata). — No plants appear to be advertised as G. 

 serrata. G. barbata is a trade name abroad. 



17. quinquefolia, Linn. (G. guinquefldra. Hill, Lam. 

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

 branched: lvs. 3-7-nerved: infl. thyrsoid- paniculate; 

 clusters 3-5-fld.; fls. bright blue; calyx one-fifth or one- 

 fourth as long as the narrowly funnel-shaped corolla. 

 N. Amer. Probably the form in cult, is var. occiden- 

 talls, Gray. Height 2-3 ft., paniculately much 

 branched: infl. more open; calyx half the length of the 

 broader corolla. B.B. 2:615. B.M. 3496.— Very pretty. 



18. Froelichii, Jan. Sts. short, almost tufted: fls. 

 blue, solitary, peduncled, nearly as long as the St.; 

 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- 

 exposure to sunlight. 



19. asclepiadea, Linn. St. strict, about 1-1 J^ ft. 

 tall: lvs. sessile, ovate-lanceolate: calyx-teeth very 

 short: fls. in spike-like racemes, dark blue, very showj'j 

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

 corolla: seeds not winged. July-Sept. S. Eu., Caucasus. 

 B.M. 1078. Gn. 48, p. 143, and 54, p. 39. G.M. 47:544. 

 Gt. 54, p. 345. G. 3:.59; 8:481; 13:403; 21:233. Var. 

 alba, a white-fld. form is excellent but perhaps not 

 known outside of English trade. Shade or half-shade, 

 and moist, deep soil rich in humus. 



20. Pneumonanthe, Linn. St. erect: fls. dark blue 

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

 corolla club-shaped; lobes ovate, acute, mucronate, 

 much longer than the appendages. Aug.-Oct. Moun- 

 tain 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. Saponaria, Linn. (G. Catesbxi, Walt., not Andr.). 

 Barrel or Soapwort Gentian. St. ascending: fls. 

 hght blue, club-shaped; calyx-lobes linear or oblong, 

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

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

 longer than the 2-cleft and raany-toothed intervening 

 appendages. N. Amer. B.M. 1039. (Hooker is prob- 

 ably wrong in referring this picture to G. Andrewsii, 

 although the calyx-lobes in the plate are not narrow 

 enough.) — Cult, like preceding. 



22. Andrewsii, Griseb. (G. Ca(fs6*i', Andr., not Walt.). 

 Closed, Blind or Bottle Gentian. Fig. 1626. St. 

 ascending: fls. purplish blue; calyx-lobes lanceolate to 

 ovate, usually spreading or recurved, shorter than the 

 calyx-tube; corolla-lobes entirely obliterated, the teeth 

 at the top being supposed to be the remains of the
