Linaria Petraea Jord. (Plate V)

May be only a variety of the above, of looser habit, with blue-violet flowers, usually without any orange, and seeds less broadly winged.

It grows in similar places, but is far from common, except in the Jura. It reaches a height of about 6600 feet above Lanslebourg in Southern Savoy. It is not infrequent above Argentine in Haute-Savoie, whence came the plant figured, and above Zinal. It is probably biennial.

Linaria Striata Dc

Stem 1-1 1/2 feet high, glabrous, very leafy. Lower leaves in whorls of 3-4; upper ones single, linear-lanceolate, acute. Flowers pale lilac or mauve streaked with violet. Palate yellow, in long, loose, spiked racemes. Spur of corolla straight, obtuse, short.

Waste, stony places and hillsides, up to 4500 feet in Savoy. June to September.

Distribution

Southern Switzerland (very rare), France and Western Europe from the Pyrenees to Germany, Scandinavia and Dalmatia.

Linaria Minor Desf, L. Viscida Moench

This small glandular-pubescent annual species, with minute pale yellow and mauve flowers, is sometimes seen as a weed between the metals of railways and other waste places in sub-alpine France and Switzerland, just as it appears in the plains of those countries and in England.

Scrophularia L. Figwort

Rather tall herbs, with flowers in panicled cymes, small, greenish purple, yellow or violet. Corolla 2-lipped, not spurred. Tube ventricose. Stamens 4, with a scale representing the 5th. Stigma notched. Capsule ovoid, acute.

About 120 species inhabiting Europe, temperate Asia, Africa, and N. America.

Scrophularia Canina L

Plant 1-2 1/2 feet high, glabrous, nearly simple, with a loose-branched glandular panicle of small flowers which are reddish brown mixed with white. Upper lip of corolla one-third as long as the tube. Leaves pinnatifid.

Stony places, dry beds of mountain torrents, and debris, here and there in Switzerland, commoner in Southern France. July, August.

Distribution

Central and Southern Europe, Corsica, Asia Minor, N. Africa.

Scrophularia Hoppei Koch

Closely allied to the last. The upper lip of corolla longer, i.e. more than half as long as the tube. Flowers reddish brown, with white margin. Anthers bright orange-coloured. Leaves pinnatifid or pinnate. Segments inciso-dentate, deeper and broader than in the last.

Dry, stony places in sub-alpine valleys. June to September. It ascends to 6600 feet near Lanslebourg in Southern Savoy.

Distribution

Alps, Jura, Pyrenees, Cevennes, Auvergne; Central Europe.

Erinus L. Erinus Alpinus L

The only species. A small tufted, creeping plant. Leaves spathulate, serrate or crenate; stem-leaves alternate, usually hairy. Flowers in terminal corymbs, rose-coloured (very variable). Corolla saucer-shaped, nearly regular, with 5 emarginate lobes and slender tube.

Rocky Alpine and sub-alpine pastures, dry beds of streams, rocks and walls, descending to the plains in both Switzerland and Savoy. May to October.

Distribution

Central and Western Alps, Jura, Cevennes, Corbieres, Pyrenees, Spain, Sardinia, Balearic Isles, Algeria.
