CAMPANULA 



hairs, VA-3 in. long, 1-2 in. wide, with a cordate, ovate- 

 oblong blade shorter than the petiole ; upper ones ses- 

 sile, ovate, acute : fls. in dense 'heads or glomes, 15-20 

 in the terminal heads, fewer in the axillary ones. Eu., 

 Armenia, Persia, Siberia. 

 B.M. 2649 is var. specidsa, 

 which has the largest fls. 

 L.B.C. 6:505 is var. sparsi- 

 fl6ra, with much smaller 

 clusters. — This is one of the 

 earliest flowcriiiu' and easi-

 B.M. 1973. — Not advertised 

 in Amer. at present. C 

 celtidifdlia, Boiss., referred to the above, may be a 

 strongly marked variety. A plant once cult, at Harvard 

 Botanic Gardens has very characteristic, perfectly el 

 liptical Ivs., blue fls., and more open inflorescence. 



12. thyraoldes, Linn. Biennial : height 1-1}4 ft 

 stem grooved : Ivs. all covered with long hairs at the 

 margin ; root-lvs. sessile, spatulate or obtusely lanceo 

 late, 2J-2 in. long, % in. wide, in adense rosette, lying on 

 the ground ; upper Ivs. more narrow and acute : fls 

 40-50, sulfur or creamy yeUow, in a dense thyrse-like 

 spike, which may be 6 in. long and 2% m. broad : stjle 

 exserted. B.M. "1290. L.B.C. 17: 1644. -Intermingled 

 with the fls. in the spike are Ivs. which are longer than 

 the fls.. which is not true of C. laetiflora. Should not 

 be confounded with C. thyrsoidea, Lapeyr., which = 

 C. speciosa. No blue or purple forms are known. The

 Vid&lli, H. C. Wats. Perennial : height 1- 



stem branching from the base : some branches short 

 sterile, others tall, floriferous, all grooved, clammy 

 glossy : Ivs. 3-4 in. long, oblong-spatulate, coarsely ser 

 rate, thick, fleshy, firm, viscid, the upper ones gradually 

 becoming bracts : fls. 2 in. long, nodding, about 9 in a 

 loose terminal raceme ; calyx lobes triangular, thick, one 

 fourth shorter than the corolla ; corolla tubular, swelled 

 below, constricted above, with a yellow base. Azores

 long as the broadly bell-shaped corolla : fls. numerous,

Var. compActa, Hort. S.M. 2:97. Gn. 47, p. 86 (with

 and one of the oldest. Much grown in pots for exhibi-

 venient for conservatory, but larks the characteristic 

 tall, pyramidal habit.

 date, covered with soft hairs ; stem-lvs. sessile, more 

 acuminate: peduncle 1-fid. : calyx lobes long-acuminate, 

 one-third shorter than the corolla : fls. 6-15 in a loose 

 spike or raceme about 8 in. long, erect, very large, 2J^ 

 in. long, purple or dark blue, hairy. Eu., Persia. Var. 

 macrdntha, Sims (C. macrdntha, Fischer), is commoner 

 in cult, than the type, a little hairier, with a glabrous 

 calyx and very large fls. B.M. 2553 and 3347. R.H. 

 1897, p. 2.39. Var. erioc4rpa, DC, has the stem 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 in their wild gardens. The stem-lvs. 

 are probably the largest of any of the garden kinds, 

 often 3yi in. long and 2 in. wide.
