| + | Glabrous and erect low herbs with dark-colored aromatic roots: Lvs. palmately lobed or dissected, petioled, the st.-lvs. often sessile and more simple: fls. polygamous, the sterile long-pedicelled and the fertile short-pedicelled; calyx with 5 foliaceous lobes, more or less tuberculate; petals oblong-ovate, connivent: fr. compressed. — Perhaps a half-dozen species, in Eu. and W. Asia, bearing fls. in leafy-involucred umbels and umbellules, the fls. being white, rose-colored or blush. The astrantias grow a foot or more high, making interesting branching plants for the border, particularly in moist places. Prop, by seeds, and easily by divisions in autumn or spring. |
