X. BARTSIA. BARTSIA. 
Herbs, usually half parasitical on the roots of other plants, with erect 
stems, opposite leaves, and yellow or purple flowers in terminal spikes. 
Calyx tubular or campanulate, 4-cleft. Corolla with a distinct tube ; 
the limb 2-lipped; the upper lip erect, concave, entire or notched, but 
without spreading lobes. Stamens 4, in pairs; the cells of the anthers 
pointed at the base. Capsule opening in 2 valves in the middle = the 
cells. Seeds many, more or less striated or furrowed. 
Rather 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 it appears to me a more natural course to 
consider these as sections of one genus, distinguished from Fuphrasia 
by the corolla.

1. B. alpina, on (fig. 7 66). yee B. ae ase 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-purple, 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 winged seeds. 
In mountain pastures, in the higher chains of central and northern 
Burope, to the Arctic regions. Rare in the higher mountains of Scot- 
land and the north of England, and unknown in Ireland. Fl. summer. 
2. B. viscosa, Linn. (fig. 767). Viscid B.—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 yellow, in a long terminal 
spike; the calyx tubular, 6 lines long, with 4 lanceolate lobes; the 
corolla half as long again, with the lower lip longer than the upper one. 
Anthers hairy. Capsule oblong, with very numerous, minute, scarcely 
striated seeds. Fufragia viscosa, Griseb. 
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. B. Odontites, Huds. (fig. 768). Red B.—An erect, branching 
annual, seldom a foot high, slightly downy, and not glutinous. Leaves 
lanceolate and toothed. Flowers of a purplish red, numerous in 1- 
sided spikes; the calyx campanulate, 4-cleft; the upper lip of the
