Geranium, crane's bill, in botany, a genus of the monodelphia decandria clas. It has but one stylum; 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 cicatarium, or hemlock-leaved crane's bill; the macchatum, or mushed crane's bill; the maritimum, or sea crane's bill; the nodulum, 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 pulchillum, or common dove's-foot crane's bill; the columbinum, or long-stalked dove's-foot crane's bill; the dissecum, 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 dispensaries.
