1. GERANIUM (Crane's-bill).-Petals regular; stamens 10, 5 of which are alternately larger, and have glands at the base; fruit beaked, separating into 5 capsules, each with a long awn, which is naked (not bearded) on the inside. Name from the Greek géranos, a crane, from a fancied resemblance of the fruit to the beak of that bird.

2. ERÓDIUM (Stork's-bill).-Petals regular; stamens 10, of which 5 are imperfect; glands 5 at the base of the perfect stamens; fruit beaked, separating into 5 capsules, each with a long spiral awn, bearded on the inside. Name from the Greek erodion, a heron, from the resemblance of the fruit to the beak of that bird.

1. G. sanguíneum (Bloody Crane's-bill).—Root-leaves nearly round, with 7 deeply-cut lobes, each of which is 3-cleft; stem-leaves 5 or 3-lobed. Plant perennial. This species is, from May to September, so beautiful with its large flowers of bright purple, that we regret that it is not more frequent. It produces a large quantity of foliage; its stem is hairy, swelling at the joints, and about a foot or a foot and a half high. Though not a common flower, it grows abundantly on some limestone and magnesian soils. In a very interesting paper, written by Mr. W. Thompson, on the relation between geological strata and the plants growing on their superincumbent soils, the author remarks:-" The basaltic ranges claim certain species, which, if not peculiar to them,

are at least more luxuriant when they are grown upon whinstone soil. The native Gerania I have always found thriving best in such districts. Geranium sanguineum, the most elegant of the genus, is richer in its tints and stronger near Edinburgh and on the Carrick shore of Ayrshire than any where else throughout the whole range of my botanical excursions. On mountain lime it is slender and straggling; on the basaltic ledges of Salisbury Crags, and beneath the scaurs of the Ayrshire whin, it exhibits the same dense bed of flowers, with a thickness of stem, compactness of leaf, and a hairiness of clothing so different, as almost to mark it out as specifically distinct from the G. sanguineum of North Wales, and its lakes. The G. sanguineum of Carrick extends nearly a mile along the shore, in one continued tract of beauty, exhibiting a luxuriance superior to that of any other flower of distinguished loveliness which our island produces." This author also describes the flower as growing, with the Broom-rape, along the ledges of the cliff in another district of mountain limestone, St. Vincent's Rock, and Clifton Downs, near Bristol. A variety of this Crane's-bill has been found by other botanists on the sands of Walney Island, in Lancashire, with pale flesh-coloured flowers, varied with purple.
