dant in the extreme west of Europe, extending through central France, east- 

 ward to the Rhine. In Britain, common in Ireland and western England, 

 as far north as the Isle of Man, and more sparingly in the east, from 

 Sussex in the south to Yorkshire in the north. Fl. summer and autumn. 



9. Corn Campanula. Campanula hybrida, Linn. 

 (Eng. Bot. t. 375.) 



A nearly simple annual, erect or decimibent, branched at the base, 6 to 8 

 inches high, and rather hairy. Leaves oblong, much waved at the edges. 

 Flowers sessUe in the axils of the upper leaves, remarkable for their long, 

 narrow, triangular ovary and capside, crowned by the linear or oblong leafy 

 segments of the calyx. CoroUa blue, much shorter than the calyx, and very 

 open. The capsule opens by short clefts close under the segments of the 

 calyx. Seeds very bright and shining. 



A cornfield weed, apparently of southern origin, but now widely spread 

 over a great part of Europe. Not uncommon in the cornfields of central 

 and southern England, and appears occasionally in the north and in some 

 parts of Scotland, but has not been found in Ireland. Fl. ivith the corn. 

 The Venus s looking-glass of our gardens (C. Speculum) is a nearly allied 

 species, common on the Conthient, with the same long capsule, but a much 

 larger corolla, flat, and exceeding the lobes of the calyx. These plants are 

 now usually considered as forming a distmct genus, under the name of 

 Specularia. 



XLIV. THE HEATH FAMILY. EIIIOACE.E. 



Shrubs, sometimes very low, creeping, and almost herbaceous, 

 or occasionally growing into small trees, with entire or toothed 

 undivided leaves, and flowers usually drooping, either solitary 

 or in small clusters or racemes in the axils of the leaves, or 

 forming short, terminal, leafy racemes. Calyx of 4 or 5 divi- 

 sions, either free or with a tube adhering to the ovary. Corolla 

 inferior or superior, usually ovoid or globular, sometimes small 

 and campanulate, with 4 or 5 lobes, or (in the two last anoma- 

 lous genera) with 4 or 5 nearly distinct petals. Stamens twice 

 as many, or rarely the same in number as the lobes of the co- 

 rolla, and inserted within the corolla but distinct from it ; 

 anthers opening at the top with two pores, or (in Monotropa) 

 with transverse valves. Ovary having usually as many (rarely 

 apparently twice as many) cells as the lobes of the corolla. 

 Fruit a capsule or berry, with one or several seeds in each 

 ceU ; the seeds very small, with a fleshy albumen. 



A large Order, widely spread over the whole world (excepting AustraUa), 

 especially in the temperate and colder rcijions, but not uncommon also in 

 hilly districts within the tropics. It is distinguished from all British Mono- 

 petals, except CampanulacecB, by the insertion of the stamens, and from the
