302 CAMPANULA. LCLASS v. OKDER 1. 



unfrequent in England. " Hilly pastures in Scotland ; but confined, 

 we believe, to the east side between the Firth of Forth and Montrose." 

 Perennial ; flowering in July and August. 



Few, if any of our native plants, vary so greatly as this. We have 

 enumerated the principal varieties that we have met with ; the leaves 

 vary in their size as to length and breadth, and are either smooth, 

 hairy, downy, or woolly, the flowers are either large or small, only 

 terminating the stem with a simple cluster, or with axillary ones also 

 for some distance down the stem. Of those varieties which we have 

 enumerated, the lancifolia appears to us the most like a distinct 

 species, the leaves are all truly lanceolate, the margins waved, irregu- 

 larly crenated, a fine green above and scarcely hairy, beneath pale and 

 much more hairy, the flowers small, stigma three-cleft, the lower leaves 

 have long winged footstalks, the upper with a broad one, but not 

 embracing the stem. The t. elliptica has rather small elliptic leaves, 

 elevated on a footstalk, the upper or floral leaves alone sessile, all 

 thickly clothed with short soft down, the flowers small, downy. 

 T). attenuate has nearly all its leaves sessile, or with a broad footstalk, 

 ovate lanceolate, with a long tapering point, green above and finely 

 downy, pale beneath, and soft, with spreading hairs. Tt is probable 

 that many of these varieties are, owing to the circumstances of their 

 growth with regard to the soil, and to their being more or less fre- 

 quently eaten down by cattle grazing in the pastures. It is frequently 

 cultivated for the beauty of its flowers, when their colour often becomes 

 paler, sometimes white, and their foliage larger and more luxuriant. 

 Prof. Henslow has observed the petals sometimes turn to a bunch of 

 leaves. 



*** Flowers solitary. Capsule opening at the extremity with three 

 or five valves, within the caly cine segments. (Wahlenbergia, Schrad). 



9. C. hedera'cea, Linn. (Fig. 375.) Ivy-leaved Bell-flower. Stem 

 weak, thread-like, branched; leaves smooth, stalked, sub-rotundate, 

 cordate, with angular toothed lobes.

Root small, branched, fibrous. Stem trailing, slender, thread-like, 

 much branched, angular, entangled together, and extending itself some 

 distance. Leaves numerous, opposite, or alternate, smooth, shining 

 pale green, on long slender angular footstalks, somewhat rounded, with 

 a heart-shaped base, angularly lobed in a tooth-like manner, acute, 

 Laving three principal ribs, with numerous fine branched lateral veins. 

 Flowers from the axis of the branched stem and leaves, and terminal 

 on long slender angular stalks, at first drooping, becoming erect, 

 solitary. Calyx of five slender awl-shaped segments. Corolla a 

 delicate pale blue, bell-shaped, in five acute sprcadirc: lobes. Stamens
