Stock tufted, with stalked, lanceolate leaves. Stems nearly simple, 3-10 inches high, erect, cottony, and leafy. Leaves linear, cottony. Flower-heads small, ovoid or cylindrical, in little clusters in the axils of the leaves, forming a long, leafy spike. Involucres with brown, shining bracts.

Antennaria Gaertner. Antennaria Dioica Gaertn. (Gnaphalium Dioicum L.). (Plate XIII)

Similar to A. carpatica, but whiter, with creeping stolons and oboval, spathulate leaves; the upper ones only are lanceolate. The capitula are white, broad, obtuse, and spreading in the male, and red and acuminate in the female. Stems 2-8 inches high, leafy.

Mountain pastures and rocks in Central, Southern, and Arctic Europe, descending occasionally to nearly sea-level in the British Isles, and attaining 9400 feet in the Alps. Also found in Russian Asia and North America.

A useful creeping plant for covering rocks and stones; it likes plenty of limestone.

Capitula small, few-flowered in racemes or panicles. Involucral bracts in few rows, margins scarious. Receptacle very narrow. Flowers all tubular, outer female, inner male or perfect. No pappus. Bitter or aromatic herbs, often somewhat shrubby.

A numerous genus extending over nearly the whole of the northern hemisphere from the Arctic regions to the borders of the tropics. Several are high Alpine species, and known collectively as Genippi in France and Switzerland. They do not descend to the sub-Alps, but sometimes in that zone we find A. vulgaris, A. Absinthium, and A, campestris from the plains and also;

Artemisia Incanescens Jord

Plant 1-2 1/2 feet high, smelling like terebinth, covered with white tomentum, especially in the upper portion, the stem being almost glabrous below. Leaves white-felted on both sides, not spotted, divisions of leaflets linear. Flowering heads shortly stalked and forming a long, loose panicle.

Dry, hot, and stony places in the mountains up to about 5000 feet, as near La Grave in Dauphine"; local. September.
