GERANIUM, CRANE'S BILL, in botany, a genus of the monodelphia decandria class. It has but one stylus; the stigmata are five; and the capsule is shaped like the bill of a crane. There are fifty-seven species, sixteen of which are natives of Britain, viz. the cicutarium, or hemlock-leaved crane's bill; the maschatum, or musked crane's bill; the maritimum, or sea crane's bill; the nedosum, or knotty crane's bill; the phœum, or spotted crane's bill; the sylvaticum, or mountain crane's bill; the pratense, or crowfoot crane's bill; the robertianum, or herb Robert; the lucidum, or shining dove's-foot crane's bill; the ro-
tundifolium, or round-leaved crane's bill; the perenne, or perennial dove's-foot crane's bill; the molle, or common dove's-foot crane's bill; the pusillum, or small flowered dove's-foot crane's bill; the columbinum, or long-stalked dove's-foot crane's bill; the diffeum, or jagged-leaved dove's-foot crane's bill; and the sanguineum, or bloody crane's bill. The leaves of the robertianum and pratense were formerly used as astringents, but are now left out both of the London and Edinburgh dispensatories.
