EEICACEJE. 349 



European mountains, from Switzerland to the Balkan, where it is usually, 

 but not always, a rather low, almost straggling shrub. Descending to the 

 shores of the Atlantic it is there more erect, with rather smaller flowers, a 

 form considered by many as a distinct species, under the name of E. medi- 

 terranea. It reappears in some of the western counties of Ireland in a form 

 intermediate between the extreme Continental varieties. It is not wild in 

 Great Britain, but frequently cultivated in our gardens. Fl. early spring. 



6. Cornish Heath. Srica vagans, Linn. 

 (Eng. Bot. t. 3, incorrect as to the shape of the flowers.) 



A rather low species, the leaves hnear, m fours or sometimes in threes, as 

 in the Mediterranean H. Flowers very numerous, on slender pedicels, 

 formuig terminal, oblong or cylindrical racemes. Sepals short and obtuse. 

 Corolla pink, rather small, campanulate when it first expands, but becom- 

 ing nearly globular. Ajithers very small, appearing double, protruding 

 beyond the corolla upon very slender filaments, without appendages. 



A gregarious species, often occupying large tracts of open country like the 

 Scotch H. ; ranging all round the Mediterranean from Spain to Greece, 

 Turkey, and Egypt, and ascending along the Atlantic to Cornwall and the 

 south coast of Ireland, but never penetrating very far inland. Fl. summer, 

 rather early.

VIII. 'WINTBRGREEM. PYEOLA. 



Low herbs, with a slender, shortly creeping stock ; orbicular or ovate, 

 nearly radical leaves ; and white or greenish, drooping flowers, either solitary 

 or several in a short raceme, on leafless, erect peduncles. Sepals 5, small. 

 Petals 5, distinct or shghtly joined at the base, ibrming at first a spreading 

 corolla, which persists round the capsule, assuming a globular shape. 

 Stamens 10. Capsule 5-ceUed, opening by shts in the middle of the cells. 



A small genus, confined to the northern hemisphere both in the new and 

 the old world ; allied to the Heaths in aU essential characters, although so 

 different in habit and foliage. It has been divided by modern botanists into 

 almost as many genera as it has species. 



Flowers solitary 1. One-flowered W. 



Flowers several in a raceme. 

 Leaves ovate, pointed. Flowers small, in a close one-sided 



raceme 5. Serrated W. 



Leaves ovate or rounded, obtuse. Flowers in a loose raceme, 

 usually few. 



Style much longer than the corolla, and curved 2. Xa/rger W. 



: Style longer than the coroUa, and straight 3. Intermediate W. 



Style not longer than the corolla 4. Common W. 



I. One-flovirered V^intergreen. Pyrola uuiilora, Linn. 

 (Eng. Bot. t. 146.) 

 Leaves of the common W., but rather smaller. Flower rather large, 

 always sohtary on the peduncle, drooping, nearly white, and very fragrant ; 

 the petals ovate, slightly connected at the base. The pores of the anthers 

 form little protruding tubes much more prominent than in the other species, 

 although they are sometimes observable even in the common W. Style 

 nearly straight, with a broad, 5-lobed stigma. 



In woods, in northern and Arctic Evirope, Asia, and America, and along 

 the high mountain-ranges of central Europe. Very scarce in Scotland, and 

 unknown in England or Ireland. Fl. summer.
