Illust. in fig. 818, 319. 



Genei-a '2S, species 500, chiefly abounding in tho northern temperate zone and in South 

 Africa. Of its 500 species, according to Alphonse Do Candolle, only 19 inhabit the torrid rone. 

 The Campannlaceaa are interesting chiefly for their beauty, being destitute of any important 

 known properties. 



i. CAMPAN'ULA, Tourn. (Lat. campanula, a little bell ; from the 

 form of the flowers.) Calyx mostly 5-cleft ; corolla campanulate, or 

 subrotate, 5-lobecl, closed at base by the broad, valve-like bases of the 5 

 stamens ; stigma 3 to 5-clcft ; capsule 3 to 5-celled, opening by lateral 

 pores. — Mostly 2f. . Fls. generally in racemes, sometimes spicate, or 

 few and axillary. 



§ Corolla rotate, flat, deeply 5-lobed, arranged in leafy spikes Nos. 1, 2 



§ Corolla campanulate, broadly or narrowly (a) 

 a Flowers on slender pedicels, solitary or paniclod (b). 



b Root leaves unlike tho stem leaves. Corolla large (6 to 12" broad). Nos. 3, 4 



b Root leaves and stem leaves similar. Corolla small ('i to 5" broad) Nos. 5, 6 



a Flowers sessile or nearly so. Stem erect. Gardens Nos. 7 — 9 



1 C. Americana L. St. erect; lvs. ovate-lanceolate, acuminate, uncinately ser- 

 rate, contracted to a winged petiole, veins often ciliate ; fls. axillary, sessile ; styl© 

 exserted, decurved. — A tall, erect, ornamental species in copses, woods, &c. 

 Western N". Y. and Penn. to 111., common. Also cultivated in gardens. St. 2 to 

 3f high, nearly smooth. Lvs. ending in a long point, smooth, with fine teeth. 

 Fls. blue, flat, on short stalks, or sessile, numerous, solitary, or several in each 

 upper axil, forming a terminal, leafy raceme. Corolla spreading. Aug. f (C. 

 acuminata Mx.) C. Illinoensis Frosen (in DC.) is a branching state of tho samo 

 plant. 



2 C. planiflora DC. Very glabrous; st. simple; lvs. sessile, coriaceous, 

 shining, radical, crowded, ovate or obovate, obtuse, crenulate, cauline linear-lanceo- 

 late, acute, subentire ; fls. in a spicate raceme ; cal. lobes ovate, acute, -J as long 

 as tho campanulate-rotato corolla. — Native about Hudson's Bay (Pursh.) A 

 species with numerous blue fls. Stem about a span high, f (C. nitida Ait.) 



3 C. rotundifolia L. Hare Bell. St. weak, slender; radical lvs. ovate or 

 reniform-cordate ; cauline, linear, entire ; fls. few, nodding. — Fine and delicate, 

 with blue, bell-shaped fls. On damp rocks, rocky streams, N. States and Brit. 

 Am. St. a foot or more high, smooth. The root lvs. generally decay on the 

 opening of tho flowers, so that a specimen with these (7 to 10" by 4 to 7") is 

 rather rare. Cauline lvs. smooth, linear, 2' long and scarcely a line in width. 

 Fis. terminal, in a loose panicle, drooping. Boot creeping, perennial. Jn., Jl. 



4 C. persicifolia L. St. angular, erect ; lvs. rigid, obscurely crenate-ser- 

 rate, radical oblong-obovate, cauline lance-linear; fls. large, broadly campanulaKfe.
