CAMPANULA 



tate, lower petiolate, ovate-oblong, subcordate; st.- 

 lvs. sessile, ovate-lanceolate: calyx-lobes acuminate, 

 spreading, half as long as the broadly bell-shaped 

 corolla: fls. numerous, in pyramidal racemes, pale blue 

 varying to white and darker at the base. G.C. III.

 Var. alba, Hort., has 

 white fls. Gn. 74, p. 

 645. J.H. III. 51:257. 

 Var compacta, Hort. 

 Dwarf er: fls. larger and 

 of better substance. 

 The compact variety is 

 very floriferous and 

 convenient for conser- 

 vatory, but lacks the 

 characteristic erect, 

 pyramidal habit. Gn. 

 73, p. 54. G. 18:64. 

 S.H. 2:97. C. Fer- 

 gusonii, Hort., is a hy- 

 brid of C. pyramidalis 

 and C. carpatica, re- 

 sembling a dwarf form 

 of the former in growth, 

 18 in.: petals more 

 pointed than those of 

 the latter: fls. bright 

 lilac. Gn. 66, p. 276. 

 Hybrids between C: pyramidalis and C. versicolor are 

 reported. 



FF. Raceme not pyramidal, usually looser. 



17. latifolia, Linn. Perennial, 3-4 ft.: Ivs. large, 

 doubly serrate; root-lvs. sometimes 6 in. long, petiolate, 

 cordate, covered with soft hairs; st.-lvs. sessile, more 

 acuminate: peduncle 1-fld.; calyx-lobes long-acumi- 

 nate, one-third shorter than the corolla; fls. 6-15 in a 

 loose spike or raceme about 8 in. long, erect, very large, 

 2^2 in. long, purple or dark blue, hairy. Eu., Persia. 

 G.W. 8, p. 445. Var. macrantha, Sims (C. macrantha, 

 Fisch.) is commoner in cult, than the type, a little 

 hairier, with a glabrous calyx and very large fls. B.M. 

 2553, 3347. R.H. 1897, p. 239. J.H. III. 60:263. Var. 

 eriocarpa, DC., has the st. and Ivs. pilose and more pallid, 

 and a hispid calyx- tube. There is a white-fld. form. It 

 is native to England, and is easily naturalized there in 

 wild gardens. The st.-lvs. are probably the largest of 

 any of the garden kinds, often 3^ in. long and 2 in. wide. 



EE. Size of fls. small, less than 1 in. long. 



18. bononiensis, Linn. Perennial, 2-2^ ft.; sca- 

 brous: st. simple: Ivs. serrulate, ovate-acuminate, pallid 

 beneath; root-lvs. cordate-petiolate; upper Ivs. clasp- 

 ing: calyx-lobes acuminate, one-fourth shorter than the 

 funnel-shaped corolla: fls. normally purplish, in a long, 

 loose, pyramidal spike, which may be 2 ft. long, with 

 60-100 small fls.; corolla %in. long and broad. E. Eu., 

 W. Siberia, and Caucasus. Var. ruthenica (C. ruthen- 

 ica, Bieb.), has Ivs. wider and tomentose beneath. 

 Caucasus and Tauria. B.M. 2653. There is a white- 

 fld. form. The fls. are much smaller than in C. latifolia, 

 and the raceme is much larger. 



19. rhomboidalis, Linn. Perennial, 1 ft., sometimes 

 2 ft.: st. simple, erect: Ivs. sessile, ovate-acute, serrate: 



766. Campanula pyramidalis. 



calyx-lobes awl-shaped, one-half shorter than the bell- 

 shaped corolla; fls. 8-10 in an almost corymbose 

 raceme, the lower pedicels of which may be 3 in. long, 

 the uppermost 1 in. or less; corolla purplish blue, 1 in. 

 long, and a little wider. Mts. of Eu. B.M. 551 (as 

 C. azurea). J.H. III. 50:541. Var. alba, Hort., has 

 white fls. G.W. 3, p. 14. It flowers in July and 

 August, after which the sts. and Ivs. die down quickly. 



20. Trachelium, Linn. THROATWORT. Fig. 767. 

 Perennial, 2-3 ft.: st. angular, somewhat bristly (as 

 also the fls.) : Ivs. rough, acuminate, coarsely crenate- 

 dentate; root-lvs. cordate, ovate, short-stalked: calyx- 

 lobes erect, triangular-acuminate, one-third shorter 

 than the bell-shaped blue or white corolla: peduncle 

 1-3-fld.; fls. erect at first, at length tending to droop 

 in a loose raceme, which may be 12-18 in. long: caps, 

 nodding. Eu., Caucasus, Siberia, Japan, and run wild 

 in parts of N. Amer. R.H. 1897, p. 239. There is a 

 double-fld. form and variations in color. One of the 

 commonest and hardiest of the border plants, often 

 running out the other campanulas, and passing under 

 many names, especially as C. urticifolia. 



21. rapunculoides, Linn. Fig. 768. Perennial, 2-4 

 ft.: st. indistinctly pubescent or almost smooth: Ivs. 

 rough, ovate-acuminate; root-lvs. petiolate, cordate, 

 crenulate; st.-lvs. serrulate: calyx a little rougher than 

 in C. Trachelium, the lobes linear-lanceolate, at length 

 reflexed, one-fourth length of the oblong-campanu- 

 late bright blue corolla; fls. soon declined or nodding, 

 in long mostly 1-sided racemes or spikes, bright blue. 

 Eu., Caucasus, Siberia, and common in patches on old 

 roadsides and about yards. Summer. Gn. M. 14:9. 



22. versicolor, Sibth. & Smith. Perennial, 3-4 ft.; 

 plant glabrous: st. ascending: Ivs. serrate; root-lvs. 

 long-petioled, ovate-acute, subcordate; st.-lvs. short- 

 petioled, ovate-lanceolate, acuminate: calyx-teeth 

 acuminate, spreading, at length reflexed, one-half as 

 long as the corolla: fls. in long, spicate racemes; style 



exserted: caps, spheroid. Greece. 



ccc. Infl. an open, compound panicle. 

 23. divaricata, Michx. Glabrous peren- 

 nial, 1-3 ft.: st. erect, slender, paniculate 

 above: branches slender, divergent: Ivs. 

 sparse, subsessile, ovate-lanceolate, acumi- 

 nate at both ends, coarsely serrate: calyx- 

 lobes awl-shaped, one- 

 half shorter than the 

 tubular, bell-shaped cor- 

 olla; fls. small, nodding, 

 pale blue, in a very open 

 and compound panicle; 

 style straight, exserted. 

 Alleghanies, from Va. to 

 ( Ga. Rare in gardens. 



GROUP III. Low-growing 

 or rock-garden cam- 

 panulas, mostly less 

 than a foot or 15 in. 

 high. Nos. 24-49. 

 A. Calyx with an append- 

 age at the base of 

 each sinus , often 

 minute or disguised 

 in form. 

 B. Throat of corolla 



spotted violet. 

 24. punctata,Lam. (C. 

 nobilis, Lindl.). Named 

 from the spotted whitish 

 corolla, the purplish 

 spots being inside and 

 showing through faintly
