Purple Toadflax (Linaria Purpurea, Mill.)

This plant has long been in cultivation in England and established in many places, old walls, waste ground, near towns. The habit is erect. The plant is smooth. The stem is leafy. The leaves are linear, lance-shaped, scattered, the radical leaves irregularly in fours. The flowers are purple, in long, narrow racemes. The sepals are linear, not so long as the capsule. The corolla has a long, incurved spur, 2-3 times as long as the flower-stalks. The lips may be purple, the flower yellow otherwise. The seeds are angular, netted. The plant is 1-3 ft. high, and flowers in July and August, being a herbaceous perennial.

Great Snapdragon (Antirrhinum Majus, L.)

This plant is an alien, which has become naturalized in many places, as on old walls and calcareous cliffs, being an escape from gardens, where it has been long cultivated generally.

The leaves are oblong, linear, lance-shaped, opposite or alternate, devoid of hairs. The flowers are purple, white, yellow or crimson, in dense racemes, glandular, downy, with ovate, narrow-pointed bracts. The ultimate flower-stalks are erect. The sepals are ovate, unequal, blunt, shorter than the corolla. The palate is yellow, the upper lip divided into two nearly to the base. The spur is hairy within. The capsule is glandular. The seeds are black or brown, longitudinally ribbed, prickly, oblong, ovoid. The plant is 1-2 ft. high, flowering from July to September, and is a herbaceous perennial.

The flowers are large, bright-blue, in more or less corymb-like racemes, with few flowers, downy, hairy, without glands, the hairs crisped. The bracts are more or less opposite. The sepals are linear to oblong, blunt, not so long as the capsule. The flower-stalks are long and erect. The ultimate flower-stalks are stiff. The style is short and slender. The capsule is oblong, ovate, narrow-pointed, the valves bifid, the seeds nearly flat. The plant is 2-4 in. high, flowering in July and August, and is a herbaceous perennial.

Alpine Bartsia (Bartsia Alpina, L.)

The stem is simple, erect, square or round, leafy. The leaves are opposite, stalkless, egg-shaped, bluntly toothed, the upper heart-shaped, clasping, leathery, blunt. The bracts are purplish. The flowers are bluish-purple, in a short, dense, leafy spike, downy. The calyx is purplish, clammy, with egg-shaped to lance-shaped lobes. The lips of the glandular corolla are small. The anthers project, and are hairy and bearded. The capsule is longer than the sepals. The seeds are small, numerous, winged. The plant is 4-8 in. high, flowering from June to August, and is a herbaceous perennial.

Rhinanthus Borealis, Druce

The habitat of this plant is Scottish mountain pastures, corries. The habit is erect, the stem simple, densely hairy, with no black striae, the internodes more or less long.
