FIG. 347. FLOWERING BRANCH OF CAMPANULA MEDIUM.
C. peregrina (foreign).* fl. disposed in a dense spicate raceme, sessile; corollas of a dark violet colour at the base, not so deep in the middle, and paler towards the margins, funnel-shaped. July. l. crenated; lower ones obovate; superior ones ovate, acute. Stem simple, angular. h. 2ft. Mount Lebanon, 1794. Borders. (B. M. 1257.)
C. persicæfolia (Peach-leaved).* fl. terminal and axillary, pedunculate, solitary, inclined, racemose; corollas blue and all the intermediate shades to white, large, broadly campanulate. July. l. glabrous, stiff, crenulated; radical ones lanceolate-obovate; cauline ones linear-lanceolate. Stems nearly simple. h. 1ft. to 3ft. Britain. (Sy. En. B. 871.) The forms of C. persicæfolia are very numerous in gardens. The following are well worth growing: alba, pure white, single-flowered; alba coronata, pure white, semi-double; alba fl.-pl., flowers very double and Camellia-like, constituting one of the best hardy flowers for cutting; cærulea coronata, blue, in form like the white; cærulea fl.-pl., flowers semi-double.
C. phrygia (Phrygian). fl., corolla bluish-violet, spreading, having the nerves more intensely coloured. July. l. ovate-lanceolate, crenated; lower ones obtuse, upper acute. Stem branched. Branches very naked, divaricate, each terminating in a single flower. h. 3in. to 6in. Mount Olympus, 1820. Rockery annual.
C. planiflora (flat-flowered). A synonym of C. nitida.
C. Portenschlagiana (Portenschlag's).* fl. light blue-purple, erect, or nearly so, bell-shaped, with spreading segments, several at the ends of the shoots, and one or two in the upper axils. June, July. l., radical ones broadly reniform, conspicuously but irregularly toothed, on long slender petioles; cauline ones passing from reniform to ovate. h. 6in. to 9in. South Europe. Rockery. SYN. C. muralis. (B. R. 1995.)
C. primulæfolia (Primula-leaved). fl. disposed in a spicate raceme; corolla blue or purple, with a whitish downy bottom, campanulately rotate, nearly glabrous. July. l. unequally and doubly crenated; radical ones lanceolate, bluntish; cauline ones ovate-oblong, acute. Stem hispid, simple. h. 1ft. to 3ft. Portugal. Borders. (B. M. 4879.)
C. pulla (russet).* fl. terminal, large for the size of the plant; corollas violaceous-blue, campanulate. June. l. glabrous, crenulately toothed; lower ones on short petioles, ovate-roundish; superior ones sessile, ovate, acute. Stems rarely pilose at the base. h. 3in. to 6in. Eastern Europe, 1779. Rockery, in rich sandy peat and leaf soil. (L. B. C. 554.)
C. pumila (dwarf). A synonym of C. pusilla.
FIG. 348. UPPER PORTION OF FLOWERING STEM OF CAMPANULA PUNCTATA.
C. punctata (dotted). fl. whitish, spotted with red on the inner surface; large, pendulous. l. ovate-acute, somewhat crenate. Stem simple, erect, few-flowered. h. 1½ft. Siberia, Japan, &c. Border perennial. See Fig. 348.
C. pusilla (small).* fl. axillary and terminal at the upper part of the slender stems, pendulous, bell-shaped, passing from deep blue to white. July, August. l., radical ones tufted, broadly ovate or roundish, slightly cordate, obtusely serrated, on petioles longer than the laminæ; cauline ones linear-lanceolate, distinctly toothed, sessile. h. 4in. to 6in. Southern Europe. SYN. C. pumila. (B. M. 512.) There is a pale-coloured variety named pallida, and a pure white variety named alba, both of which, as well as the species, are most desirable for the embellishment of rockeries, or for planting in sandy soil as a front line for a border.
FIG. 349. CAMPANULA PYRAMIDALIS, showing Habit and Flower.
C. pyramidalis (pyramidal).* Chimney Bell-flower. fl. very numerous, pedicellate, usually three together from the same bract, the whole disposed in a large pyramidal raceme, which is loose at the base; corollas pale blue or white, with a dark base. July. l. glandularly toothed; lower ones petiolate, ovate-oblong, somewhat cordate; cauline ones sessile, ovate-lanceolate. Stem nearly simple, but furnished with floriferous branchlets. h. 4ft. to 5ft. Europe, 1596. See Figs. 349 and 350. There are several excellent varieties, but the light and dark blue and white are the best. Borders, and for pot culture.
C. Raineri (Rainer's).* fl. blue, erect; corolla turbinate. June. l. almost sessile, ovate, tomentose, remotely serrated; lower ones the smallest, obovate. Stems erect, firm, branched. Branches one-flowered, leafy. h. 2in. to 3in. Switzerland, Italy, &c., 1826. A beautiful little alpine, requiring a warm position in rich gritty soil; it must be religiously protected against slugs. (F. d. S. 1908.)
