12 CAMPANULACE^. Campanula. 



§ 2. Calyx wholly destitute of appendages at the sinuses : stigmas and cells of 



the ovary 3.

 -1— Openings of the capsule toward its summit: low and one-flowered arctic-alpine plants. 



C. lasiocarpa, Cham. An inch to a span high, rather slender : leaves denticulate or 

 laciniate with subulate salient teeth ; the radical spatulate or oblong, mostly acute, and 

 slender-petiuled ; caulme few and lanceolate or linear : calyx-tube obconical, villous ; its 

 lobes lanceolate-linear, laciniate-toothed : corolla between half and an inch long, broadly 

 oblong-campanulate, glabrous within ; its tube twice the length of its lobes and surpassing

 entire or nearly so, thickish ; the lowest spatulate or oblong, obtuse, uppermost linear : 

 flower small (4 to 6 lines long), rather slender-peduncled : calyx-tube often pubescent, nearly

++ Rather coarse and large, pubescent, many-flowered European species, escaped from cultivated 

 ground and sparingly naturalized near the Northern Atlantic coast. 



C. KAPUNCULOiDES, L. Minutely roughish-pubescent : stem 1 to 3 feet high, simple or at 

 length branching : leaves more or less crenate and acuminate ; the lower and radical ones 

 cordate and long-petioled ; upper lanceolate and passing into bracts of the loose virgate 

 mostly one-sided true raceme : corolla oblong-campanulate deeply G-lobed (an inch long), 

 blue : capsule globular, nodding on a short pedicel. — Fl. Dan. t. 1327. — Roadsides and 

 fields, Canada to Penn. (Nat. from Eu.) 

 "•C. glomeeAta, L. Pubescent, a foot high: leaves serrulate; the lowest and radical cor- 

 date-oblong and slender-petioled ; the others closely sessile, ovate-lanceolate or oblong : 

 flowers sessile in a few terminal and upper axillary clusters, exceeding the leafy bracts : 

 corolla (an inch long) oblong-campanulate : capsule erect, opening near the base. — Fl. 

 Dan. t. 1328. — Eoadsides, E. Massachusetts: rare. (Nat. from Eu.) 



++ ++ Slender or low species, with filiform, rootstocks, mostly glabrous, one-several-flowered (in- 

 florescence centrifugal): peduncles or pedicels slender, 



^ When se.veral racemosely disposed on the simple smooth stem : capsule nodding : radical leaves 

 roundish or ovate and often cordate, at least on sterile shoots. (Hare-uells. ) 



bC. Scheuohzeri, Vill. Stem a span to a foot high, 1-4-flowered, more commonly 1- 

 flowered : cauline leaves linear or narrowly lanceolate, sessile, not rarely denticulate ; 

 lowest cauline spatulate : flower-bud nodding : campanulate corolla half to three-fourths 

 inch long, little or moderately exceeding the slender linear-subulate calyx-lobes. — Prosp. 22

 1-flowered, with the base or lower part of the leaves hirsute-ciliate, and calyx-lobes spar- 

 ingly denticulate. (Eu., N. Asia.) 



Var. heterodoxa. Stems more diffuse and leafy : cauline leaves from lanceolate to 

 ovate-lanceolate (2 or 3 to even 5 lines wide), often sharply denticulate, nearly all tapering 

 into margined petioles; the radical round-cordate or ovate (sometimes an inch in diameter) : 

 corolla two-thirds to a full inch long : slender calyx-lobes more spreading or even reflexed,
