Rhinanthus Sub-Alpinus Schinz And Thellung. (Plate XXVIII)

Plant 6-12 inches high. Stem streaked with black, almost glabrous. Leaves broadly lanceolate, crenate-dentate, sub-acute. Bracts triangular, ending in a short point, the lower teeth being subulate, aristate. Upper lip of corolla with violet lobes, narrowly conical, sub-acute, 2 mm. long.

Alpine and sub-alpine meadows in the Alps and Jura, and also in the plain of Switzerland.

The writer did not see the plant which was drawn and here figured, and cannot be sure that it belongs to this species.

Pedicularis L. Lousewort

Flowers usually in bracteate spikes or racemes, large and showy, red or yellow. Calyx tubular or campanulate, often inflated, 2-5 toothed. Corolla 2-lipped, tube often dilated, upper lip entire or notched, lower lip 3-lobed. Stamens 4. Anthers hairy. Erect herbs with deeply divided leaves, turning black when dry, parasitic upon roots.

There are about 150 species inhabiting the mountainous parts of Europe, Asia, Africa, and America. Many are acrid, and consequently harmful to the pastures. Nearly all are Alpine or sub-alpine, and the great majority in the Alps grow from about 4500-6000 feet, and having been fully treated in the author's Alpine Plants of Europe, he does not propose to repeat many of those descriptions here, but to give a brief summary of them and to add a few species which grow at lower altitudes. This summary is based on that of the late A. W. Bennett.2

A

Flowers yellow. Upper lip of corolla drawn out to a long narrow beak:

P. Elongata Kerner

Stem 6-12 inches, few-leaved, nearly glabrous. Spike elongated. Calyx-teeth leaf-like, inciso-dentate, bracts glabrous, pinnatifid. Leaves deeply pinnatifid. Segments inciso-serrate. South-eastern Tyrol and Venetian Alps; rare.

C

Flowers red. Corolla beaked. Stem-leaves alternate:

P. Incamata L

D

Flowers red. Corolla not beaked. Stem-leaves alternate:

P. Sylvatica L

Stem nearly simple, leafy, about 6 inches long, prostrate or spreading. Flowers sessile, dark pink or rarely white, in short terminal heads. Calyx-lobes unequal, lower ones toothed. Leaves pinnate, with deeply cut segments. Damp meadows and pastures in the plains and sub-Alps. Western, Central, and Northern Europe. British.
