Cephalanthera

(Greek for head and anther). Orchiddcese. About 10 species of small temperate-region terrestrial orchids, allied to Epipactis and Pogonia. Some of them are western N. American, and others are European. Sepals 3; petals small, ovate; lip saccate: leaves (sometimes wanting) lanceolate or oblong: flowers mostly small (sometimes showy), in an open spike. The species are scarcely known in cultivation, but 2 Japanese species have been offered by importers. These are E. falcata Blume, yellow, and E. erecta, Blume, white.

Cephalostachyum

(Greek, head and spike). Gramineae. A few species of grasses of the bamboo tribe in E. Indies and Madagascar, one of which (C. per-gracile) has been offered in this country. Tall shrubs: spikelets in dense solitary heads at the ends of the branches or in scattered glomerules, the heads bristly with the subtending leaves; stamens 6; empty glumes 1-2; style long, 2-3-cleft: fruit elongated and beaked. C. pergracile, Munro. Forty ft., stems 2-3 in. thick: leaves 14 in. or less long: an elegant species, growing in clumps. Burma. It is offered in S. Calif. In Fla., it loses most of its leaves in winter, but the new growth in spring and summer is very attractive; it is said not to do well there on high dry pine land, preferring moderately moist soil; it needs much water in summer, and responds readily to fertilizer. l. H. B.

Cerasus

(from Cerasunt or Cerasonte, a place in Asia Minor on the Black Sea, whence cherries are said to have been brought to Italy before Christ). Cherry. Rosacese. Tournefort in 1700 founded the genus Cera-sus, but by general usage it is now combined with Prunus inasmuch as no single important character holds clearly between the two groups. The name is sometimes kept distinct in trade lists, representing the cherries as distinct from the plums. Botanically, the group is distinguished from Prunus proper (the plum group) in having conduplicate vernation (young leaves with the halves folded together) rather than involute vernation, flowers more characteristically in umbels or racemes, fruit mostly lacking bloom and pubescence, and the stone not corrugated or pitted. See Prunus.

Branches often whorled as are the leaves, which are narrow, strongly re volute and thus almost tubular: flowers dioecious, 2-3-whorled in the axils, sessile; sepals, petals and stamens, each 2. - Only 1 species.

Michx. Height 2-8 ft.: branches subverti-cillate, marked with scars of numerous fallen leaves, the younger and upper ones only retaining foliage: leaves crowded, 1/2-3/4in.. long, linear, rigid, shining, pale: flowers inconspicuous reddish, whorled in the axils: drupe round, orange-yellow, berry-like.
