SCEOPHULAEIiraiE. 405 



Eatlier a large genus, chiefly European, north African, and west Asiatic, 

 but also with a considerable number of South American species. It has 

 been divided into three or four distinct genera, distinguished chiefly by the 

 seeds ; but although I had myself on anotlier occasion adopted three of 

 them, it appears to me now to be a more natural and convenient course to 

 consider them as sections of one genus, distinguished from Eyehright by 

 the form of the corolla. 



Spites panicled. Flowers pink. Seeds few, pendulous 3. Red B. 



Spikes simple or nearly so. Seeds numerous. 



Spikes short. Flowers duU-purple. Calyx campanulate. Seeds deeply 



furrowed l- Alpine B. 



Spikes long. Flowers yellow. Calyx tubular. Seeds scarcely striated 2. Viscid B. 



1. Alpine Bartsia. Bartsia alpina, Linn. 

 (Eng. Bot. t. 361.) 



A hairy perennial, with a short rootstock, and erect stem 6 to 8 inches 

 high. Leaves sessile, ovate and crenate, the floral ones rather smaller. 

 Flowers in a short, leafy spike. Calyx deeply 4-lobed. Corolla of a dull 

 livid-pui-ple, 8 or 9 lines long, with a tube much longer than the calyx, 

 and very short lobes to the lower lip. Anthers very hairy. Capsule ovate, 

 longer than the calyx, with several deeply furrowed, almost vdnged seeds. 



In mountain pastures, in the higher chains of central and northern 

 Europe, to the Arctic regions. Eare in the higher mountains of Scotland 

 and the north of England, and unknown in Ireland. Fl. summer. 



2. Viscid Bartsia. Bartsia viscosa, Linn. 



(Eng. Bot. t. 10-15.) 



An erect, rigid annual, often above a foot high, more or less clothed with 

 a short, glutinous down ; the root-fibres hard and wiry. Leaves lanceolate, 

 coarsely toothed, the floral ones alternate. Flowers yeUow, in a long ter- 

 minal spike ; the calyx tubular, 6 lines long, with 4 lanceolate lobes ; the 

 coroUa half as long again, with the lower Up longer than the upper one. 

 Anthers hairy. Capsule oblong, with very numerous, minute, scarcely 

 stiTated seeds. 



In fields and pastures, chiefly near the sea, in western Europe, and round 

 the whole Mediterranean region, and has established itself in the Canary 

 Islands and South America. In Britain, at present confined to some of the 

 southern and the western maritime counties of England, to southern Ireland, 

 and south-western Scotland. Fl. summer and autumn. 



3. Red Bartsia. Bartsia Odontites, Huds. 



(Eng. Bot. t. 1415.) 



An erect, branching annual, seldom a foot high, slightly downy, and 

 not glutinous. Leaves lanceolate and toothed. Flowers of a purplish red, 

 in numerous one-sided spikes ; the calyx campanulate, 4-cleft ; the upper 

 hp of the coroUa longer than the lower one. Aiithers scarcely hairy. Cap- 

 sule oblong, with- a few pendulous, fiuTOwed seeds, as in Eyehright, but 

 with the general habit and corolla of a Bartsia. 



In fields and waste places, aU over Europe and Eussian Asia, except the 

 extreme north. GeneraUv distributed over Britain. Fl. summer.
