The habitat of this plant is heathy places, and the plant is very rare. The habit is erect. The plant has short barren stolons below, with one or more stems from one root. The plant is devoid of hair. The leaves are oblong on the stolons, opposite, and in whorls of 3 or 4, the stem-leaves scattered, linear, blunt, alternate. The sterile branches are radical and prostrate, with ternate, lance-shaped, ovate leaves. The flowers are few, purple, with dark veins in a short raceme, on stalks as long as or less than the bracts. The sepals are linear, awl-like, acute, shorter than the spur, twice as long as the capsule, which is broad and 2-lobed. The seeds are nearly flat. The corolla has a spur parallel to the tube, which is acute, winged, tubercled on one face. The wing is fringed with teeth. The plant is 6-12 in. high, flowering in June and July, and is a herbaceous annual.
The habitat of this plant is sandy fields, dry, bare heaths, and waste places. The habit is erect, or nearly so, the stem rigid, with spreading branches, downy, and glandular. The small leaves are bracts ' above, cut, the lower stalked, finger-shaped. The flowers are dark-blue, in a raceme with few flowers, somewhat spiked. The calyx is shorter than the flower-stalk. The capsule is many-seeded, the seeds hollow on one side. The plant is 3-8 in. in height, and flowers in May and June, being an annual.
The habitat of this plant is sandy fields and bare heaths. The habit is erect, the stem simple or branched below, hairy or downy, and glandular above, as in other heath plants. The leaves are deeply divided to the base, the lower stalked, coarsely I toothed, lobed, the upper bract-like, lance-shaped. The flowers are deep blue, with darker lines, the corolla small, the calyx longer than the flower-' stalk, the raceme somewhat spiked with many I flowers, loose. The capsule is flattened at the margin, fringed with hairs on the keel, inversely heart-shaped, the seeds flat. The plant is 2-4 in. high, flowers in May and June, and is an annual. Spiked Speedwell (Veronica spicata, L.). - The habitat of this plant is dry calcareous places, chalky pastures, chalky heaths. The habit is prostrate, then ascending. The rootstock is creeping. The stem is branched below, stout, leafy. The radical leaves have a wedge-shaped base, being blunt, and are more or less stalkless, toothed above the middle, or scalloped, entire at the end, oblong, leathery. The flowers are borne in a dense spike (hence spicata) or terminal raceme, and have ovate to lance - shaped bracts, longer than the blunt sepals, fringed with hairs. The corolla has the tube as broad as long, the throat bearded. The lobes are narrow, acute. The stamens are very long. The anthers are large and purple. The style is long. The capsule is ovate, with a notch and long style, downy, as long as the sepals. The plant is 4-12 in. high, flowering in July and August, and is a herbaceous perennial.
