(Greek for head, alluding to the capitate flower-clusters). Dipsaceae. Coarse annual or perennial herbs planted to some extent in herbaries.

Much like Dipsacus, but the heads less spiny and mostly smaller: heads terminal, ovoid or globular, bearing many 4-parted yellowish, whitish or bluish florets; stamens 4, perfect; style filiform: fruit a 4-8-ribbed achene, the calyx-border often remaining on its summit. - About 30 species in the Medit. region, N. and S. Africa and W. Asia; also in Abyssinia. Leaves entire, dentate, or lobed. They are not much planted in Amer., but they make striking subjects for summer bloom, and the long stems make ihem useful for cut-flowers The bloom is something like that of scabiosa. Of simple cultivation; grown readily from seeds.

Alpina

Schrad. Perennial: tall and widely branched, 5 or 6 ft.: leaves pubescent and pinnatifid, the segments cut and decurrent: flower-heads sulfur-yellow; involucre with 8 aristate teeth. S. Eu. - A good coarse plant for summer bloom. Hardy N.

Leucantha

Schrad. Perennial: leaves pinnate-parted, the lobes linear or oblong: flowers in subglobose heads, creamy white, in autumn. S. Eu. Variable.

Transylvanica

Schrad. Annual, slender, 2-3 ft.: lower leaves lyrate; the segments serrate and the terminal one large; upper leaves pinnate-parted into linear-lanceolate divisions: flowers in globular heads on long peduncles, the ray-corollas bluish and disk-corollas whitish (flowers said to be yellow, in trade lists, to bloom June-Aug. and plant perennial). Greece and eastward.

Tatarica

Schrad. Perennial, 6 ft., rank, with striate stems, suited to the rear border, where strong effects are desired, with showy cream-white, flat heads in July and Aug.: leaves pinnate, the leaflets broad-lanceolate and serrate. Russia, Asia Minor and E. - Grows readily, and is increased by seed or dividing the clumps.
