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

 C. 3 :21B) , may he a hybrid between this audC Andre wsii. 

 It resembles O. orhroieuca in having calyx lobes of 

 unequal lengths, but as long as or longer than the calyx 

 lube, and free anthers : it resembles G. Aiidreiexii in the 

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

 (O. incarndta, Sims). B. M. IS.'JG from Carolina is not 

 cult. These forms are not considered worthy of varietal 

 rank in Gray's Syn. Fl. 



9. frigida, H.-enk. Lvs. spatulate-Iinear, obtuse: lis. 

 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 tlio 

 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 cultivation, but is inserted to 

 make clear the differences between G. ahjida of Fallas 

 and of Steven. 



10. Algida, Pall., not Stev. {G. frUjida, \-o.v. dhjida, 

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

 distinctly pedicel led ; calyx laterally cut and one-third the 

 length of the corolla; calyx teeth linear- lanceolate, 

 hardly as long as the calyx tubo 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 Ofn. 27, p. 81); 4H, 

 p. 146, and N, 2:00, Pig. 93. -This grows 4-5 in. high, 

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

 ish, with blue spots in longitudinal lines. The writer 

 has not seen Gt. 100(J. 



11. gSlida, M. Bicb. (G. dlnida. Stev., not Pall.). 

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

 or many in the upper axils, jteduncled; 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 O. septeinfida,Yiir. 

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

 Correvon. 



12. camp§stris, Linn. Annual : f1s. dark purplish 

 l)Iue; calyx 4-cut; corolla nearl}- b'.)wl-shaped, crowned; 

 anthers free; style none. 



13. MoorcroJtiana, Wall. Annual, 4-10 in. high: fls. 

 pale bhie; calyx 5-cut; corolla funnel-shaped. Hinial. 

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



14. crinita, Prcel. Pig. 897. Fringed Gentian. Bien- 

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

 <»vate-lanceolate, acutish, from a rounded or subcordate 

 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.P. 19. Mu. 4:161. B.B. 2:013. -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. ciliita, Linn. Perennial: stem ileiuose, scarcely 

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

 long: seeds smooth. Dry limestone soils. Eu. Not B.IM. 

 639,whichis G. .-iej-nf/rt. — 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. serrata, Gnnn. {G. barbSta, Frffil. G. deti'msei, 

 Griseb. O. detonsa, var. barbdta, Griseb.). Annual: 

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

 linear: corolla lobes 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 <?. (■(7'"/a. 

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

 barbata is a trade name abroad. 



17. quinquejolia, Linn. {G. qainqnefibra, 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; 

 calyx one-fifth or one-fourth as long as the narrowly 

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

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



jianiculately much branched: inflorescence more 07)en ; 

 .■alvx half the length of the broader corolla. B.B. 2 :615. 

 B.M. 3496. -Very pretty. 



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

 blue, solitary, i)eduncled, nearly as long as the stem: 

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

 — Easily grown on rockwork in compost of equal parts 

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

 posure to sunlight. 



19. asclepiadea, Linn. Stem strict: calyx teetli very 

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

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

 not winged. .luly-Sep. S. Eu., Caucasus. B.I\I. 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. PneumonAnthe, Linn. Stem erect: fls. dark blue 

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

 roUa 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 i-ool, deep, spongy soil, 

 rich in humus. Dislikes lime, ;irid prefers sandy soil. 

 Does remarkably well when planted on margins of ponds 

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

 iigijt bine, club-shaped; calyx lobes linear or oblong,

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

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

 dages. N.Amer. B.M. 10.39. — (Hooker is probably wrong 

 in referring this picture toff. ^Hrfrews it, though the calyx 

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