19. Caryophyllus, Linn

Carnation. Clove Pink Picotee. Grenadine. Figs. 801-818. Plate XXII. Cespitose, glabrous, 1-3 ft., the stems hard or almost woody below, the nodes or joints conspicuous: leaves thick, long-linear, very glaucous, keeled, 5-nerved, stiffish at the ends: flowers mostly solitary, showy, very fragrant, rose, purple or white; calyx-bracts 4, very broad, abruptly pointed. B.M. 39 (Bizarre Carnation); 1622 (variety imbricatus); 2744 (Picotees). - Generally supposed to be native to the Medit. region, but Williams gives its geographical limits as "north and west Normandy" and "south and east Punjaub" (northwestern Hindoostan). In Eu. it is largely grown as an outdoor pink, but in this country it is chiefly known as the greenhouse carnation. The American forcing type (which may be called variety longicaulis) is distinguished by very long stems and a continuous blooming habit; it is here the carnation of commerce. Garden varieties of D. Caryophyhus are numberless, and they often pass under Latinized names (D. punctatus, Hort., is one of these names). See Carnation. The carnation has been long in cultivation The bloom is now very variable in size, form and color; originally probably pale lilac.

Fragrant.

bb. Calyx-bracts half the length of the calyx, mostly narrow-pointed, more or less spreading at the tips: leaves short and spreading, the radical ones obtuse or nearly so.

Scotland to Norway and Japan. Gn. 66, p. 224. G.M. 55:28.

Mts. of S. Eu. G.C. II. 21:809-A pretty species, but difficult to establish. Grown among alpine plants. variety Freynii, Williams (D. Freynii, Vandas). Leaves rather soft, keeled, the lateral nerves obscure: stems usually 1-flowered: calyx-teeth ciliate. variety neglectus, Williams (D. neglectus, Loisel).

25. Chinensis, Linn

(D. sinensis, Hort.). Fig. 1254. Cespi-tose, glabrous, more or less creeping at base: stem forking, angled and more or less grooved, pubescent: leaves broad and nearly flat or slightly trough-shaped, 3-5-nerved: flowers large, solitary or more or less clustered, pink or lilac; the petals (at least in the wild) barbed or hairy toward the base; calyx-bracts 4, in some cultivation vars. short. China and Japan; but recent authorities consider a European pink to be but a form of it, and thereby extend its range west to Portugal. B.M. 25. The Amoor pink (D. dentosus, Fisch.) is a form known as variety macrosepalus, Franch.: it is a hardy border plant, 1 ft. high, with bright red flowers and a spot at base of each petal. variety asper, Koch (D. Seguieri, Auth.). has flowers in panicles, and the bracts squarrose - spreading: the European form of the species. D. semperflorens, Hort., is a hardy perennial form, 12-18 in., with silvery foliage and deep pink, red-eyed, fragrant flowers D. chinensis has given rise to a beautiful and variable race of garden pinks, variety Heddewigii, Regel (D. Heddewigii, Hort.). These are extensively grown from seeds, and are practically annuals, although plants may survive the winter and give a feeble bloom in the spring in mild climates.

The flowers are scarcely odorous. They are single and double, of many vivid colors; and many of the garden forms have bizarre markings. Gt. 7:328. G. 2:537. In some forms, variety laciniatus, Regel (D. laciniatus, Hort.), the petals are slashed and cut. G. 2:538. G.Z. 6:1. D. imperialis, Hort., is a name applied to a strain with strong habit and rather tall growth, mostly double. C. diadematus, Hort., is another garden strain. G. 2:538. D. cincinnatus, Lem., is a red form with shredded petals. I.H. 11:388. D. hybridus, Hort., is another set. This name (D. hybridus) is also applied to a dentosus-like form, which some regard as a hybrid of D. dentosus and some other species. A recent race of the garden pinks, with narrow petals and a star-like effect, is variety stellaris, (D. stellaris, Hort.). For portraits of garden pinks, see B.M. 5536. F.S. 11:1150; 12:1288-9; 13:1380-1. Gn. 49:82. - The garden pinks are of easy cultivation Seeds may be sown in the open where the plants are to stand, but better results are obtained, at least in the N., if plants are started in the house. Plants bloom after the first fall frosts. They grow 10-16 in. high, and should be planted 6-8 in. apart.

They are very valuable for borders and flower-gardens. Species - names now referred to D. chinensis are D. caucasicus, Sims, D. ibericus, Willd., D. ruthenicus, Roem., D. montanus, Bieb., D. collinus, Waldst. & Kit., representing the European extension of the species.
