CAMPANULA 



CAMPANULA 



uppermost 1 in. or less : corolla purplish blue, with a 

 white variety, 1 in. long and a little wider. Mts. of Eu. 

 B.M. 551, as C. aziirea. — lt flowers in July and August, 

 after which the stems and Ivs. die down quickly. 



18. TTachglium, Linn. Fig. 337. Height 2-3 ft. : stem 

 angular, covered with dense, short hairs : Ivs. rough, 

 acuminate, coarsely erenate-dentate; root- 

 Ivs. cordate, ovate, short-stalked : calyx 

 lobes erect, triangular -acuminate, one- 

 third shorter than the bell-shaped 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 : capsule 

 nodding. Eu., Caucasus, Siberia, Jai)an. 

 R.H. 1897, p. 2.'i9. 

 There is a double-ttd. 

 form. — One of the 

 commonest and hardi- 

 est of the border per- 

 ennials, often running 

 out the other Campan- 

 ulas, and hence pass- 

 i n g under many 

 names, especially C 

 urticifolia. 



19. rapunculoldes, 

 Linn. Height 2-4 ft. : 

 stem a little rougher 

 than in C. Triiche- 

 iium : Ivs. rough, 

 ovate-acuminate; root- 

 Ivs. petiolate, cordate, 

 crenulate ; stem - Ivs. 

 serrulate : calyx a lit- 

 tle rougher than in V. 

 Trachelinm: lobes lin- 

 ear-lanceolate, at 

 length rcriexed, one- 

 fourth shorter than the 

 funnel-formed corolla: 

 fls. solitary, nodding, 

 in long, racemose 

 spikes. Eu., Caucasus, 

 Siberia. 



2n. versicolor, Sibth. 

 a Sm. Height 3-4 ft. : 

 plant glabrous : stem 

 ascending : Ivs. ser- 

 rate ; root-lvs. long-petioled, ovate-acute, subcordate ; 

 stem-Ivs. short-petioled, ovate-lanceolate, acuminate : 

 calyx-teeth acuminate, spreading, at length refiexed, one- 

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

 style exserted : capsule spheroid. Greece. — Rare. 



DDD. Infloreacence an open, vompound panicle. 



21. divaricita, Michx. Glabrous: height 1-3 ft. : stem 

 erect, slender, paniculate above : branches slender, di- 

 vergent : Ivs. sparse, subsessile, ovate-lanceolate, acu- 

 minate at both ends, coarsely serrate : calyx-lobes awl- 

 shaped, one-half shorter than the tubular, bell-shaped 

 corolla : fls. small, nodding, blue, in a very open and 

 compound panicle ; style straight exserted. Alleghanies, 

 from Va. to Ga. — Rare in gardens. 



AA. Low-grorving or rock-garden Campantdas, mostly 



less than a foot hiijh 

 B. Calt/x with an appendage at the base of each sinus, 



often minute or disguised in form. 



c. Throat of corolla spotted violet. 



22. punctata, Lam. (C.ndbilis, Lindl.). Named from 

 the spotted corolla, the purplish spots being inside and 

 showing through faintly in the fresh fl. but more plainly 

 in the dried specimen. Height 1 ft. : stem with longer 

 and looser hairs than in C. alliaricefolia : upper Ivs. 

 nearly sessile, and more sharply toothed than the lower: 

 calyx-lobes one-third as long as the corolla, longer, looser 

 and hairierthan in C. a Uiaricsfolia, and the margins much 

 more recurved : peduncle 1-4-fld. : fls. nodding; corolla 

 cylindrical, 2K in. long, white, spotted within, strongly 

 ribbed. Siberia, Japan. C. nobilis has been considered 

 distinct. In P. S. 3:247 the corolla is dark violet with- 

 out, the limb hairy, while in B. M. 1723 (C'.p«»ctete) the 



337. Campanula Trachel 



corolla is white outside and not bearded. In P. S. 6: 563 



(C. nobilis, Y&T. alba) the limb is not bearded and the 

 stem is red, and not hairy. The three pictures show 

 great differences in foliage, pubescence and appendages. 

 This is one of the most interesting of all Campanulas, 

 and is, unfortunately, usually considered more quaint 

 than beautiful. Cannot be used for cutting. The spot- 

 ted throat readily separates it from all Campanulas. 

 See supplementary list for C Van Houttei, a supposed 

 hybrid. 



CO. Throat of corolla not spotted. 

 D. Stems 1-flowered. 



23. AlUdnii, Villars. Height ,3-5 in.: rootstock slen- 

 der, creeping underground, sending up stems at inter- 

 vals of H-1 in. : Ivs. few, about 7on a stem, 1-2 in. long, 

 linear-lanceolate, sessile, slightly hairy, entire, midrib 

 distinct, lower ones in a wlicrl of about 5, upper ones 

 similar but more i net : i-:ilyx-lobes lanceolate, half as

 parently no purple. Readily told fnmi C. Allioiiii by 

 the different colored, bearded and smaller fls., which 

 are rarely borne singly, and by the dense, soft hairs of 

 the stem. Commonest species in the Alps. "In the 

 rock-garden it should be grown in poor, stony soil, as it 

 is apt to become somewhat coarse when grown in rich 

 soil."-/'. W. Meyer. 



EE. Margin of corolhi nut bearded. 

 F. Fls. erect. 



25. mdllis, Linn. Perennial : velvety gray : height 

 6-8 in. : stems procumbent, about 2-fld. : root-lvs. tufted, 

 obovate or spatulate ; stem-lvs. ovate or rotund : fls. 

 loosely panicled ; calyx-lobes lanceolate, erect, half 

 shorter than the glal)rous, bell-shaped corolla ; appen- 

 dages minute, shorter than the calyx tube; corolla erect,

26. alpina, Jacq. Height 3-8 in. : stem furrowed : 

 Ivs. smaller than in C. barbata, more narrowly lanceo- 

 late, entire, hairy : fls. typically deep blue, bell-shaped, 

 with broader and shorter segments than in C barbata: 

 calyx-lobes proportionately very long, surpassing the 

 fl.-bud, and nearly as long as the flower, but widely 

 spreading. Swiss and Austrian Alps. B.M. 957. J.H. 

 III. 29: 5.— There is a white-fld. var. Int. into England 

 about 1805 by Loddiges. The plant has a characteristic 

 shaggy appearance from the hairy Ivs. Easy of cult. 



27. Sibirica, Linn. (C. Sdhenackeri, Fisch.). Seta- 

 ceous-pilose : stem erect, simple, panicled above : Ivs. 

 crenulate ; root-lvs. petioled, obovate, obtuse ; stem- 

 lvs. lanceolate-acuminate : calyx hairy, the lobes long- 

 acuminate, a third shorter than the corolla : calyx ap- 

 pendages like the lobes but half shorter and reflexed: 

 fls. 25 or more, violet, with a longer and narrower tnbe 

 than in C. alpina, and longer divisions of the limb.
