 toothed, or incised and dissected. 

 Flower - heads solitary or in loose or 

 dense corymbs at the ends of the 

 branches. Involucre hemispherical, flat, 

 or rarely bell-shaped. Eeceptacle flat,

C. arcticum. — A pretty Siberian 

 species about 1 ft. high. Flowers during 

 the summer, white tinged with lUac or 

 rose. 



Culture and Propagation. — A good 

 plant for the rockery. It grows well in 

 ordinary soil and may be raised from seeds 

 sown in gentle heat in early spring. The 

 seedlings are pricked out and by the end 

 of May will be ready for the outside. 



C. argenteum. — An herbaceous peren- 

 nial about 1 ft. high, native of the Levant. 

 Leaves twice pinnate, silvery, with acute 

 entire leaflets. Flowers in July, white. 



Culture and Propagation. — This is 

 suitable for the border or rockery, in 

 ordinary soil. May be increased by 

 dividing the roots in spring ; by cuttings 

 at the same period ; or from seeds sown 

 in gentle heat, afterwards transplanting 

 the seedlings about May to the open 

 border. 



C. carinatum [C. tricolor). — A hand- 

 some showy annual about 2 ft. high, 

 native of N. Africa. Leaves twice pin- 

 nate, fleshy, smooth. Flowers during 

 summer, white, purple &c. 



There are many iine varieties of this 

 species, among which may be mentioned : 

 Burridgeamum, with flowers 2-3 in. 

 across, symmetrically zoned with white, 

 lUac, purple, yellow, maroon &c., with a 

 dark centre. The golden-leaved form of 

 Burridgeanum is very distinct. The 

 variety album has a yellow blotch at the 

 base of the white ray florets surrounding 

 a purple disc. Luteum is a variety in 

 which the ray and disc florets are of a 

 soft nankeen-yellow. Venustum has the 

 upper half of the ray florets white, the 

 lower half purple - violet, and the disc 

 purple. Other varieties are Morning 

 Star, large primrose-yellow ; John Bright, 

 golden-yellow ; and atrococcineum or The 

 Sultan, deep crimson. 



Culture and Propagation. — Besides 

 the single forms there are also many fine 



double white and double yellow ones. 

 The species and its varieties are beauti- 

 ful plants for the flower border, or in beds 

 by ^themselves. They are easily raised 

 from seeds sown in rich sandy loam 

 in April, thinning the seedlings out to 9 

 or 12 in. apart, where they are to bloom. 

 Seeds may also be sown in sUght heat in 

 March, and the seedlings planted out at 

 the end of May. They may also be sown 

 from September to October, and the 

 plants wintered in cold frames or green- 

 houses, from which they may be trans- 

 ferred to the open ground the following 

 spring, or flowered in pots. The plants 

 will develop a bushy habit more quickly 

 if the point of the main shoot is pinched 

 out. 



C. Catananche. — A beautiful peren- 

 nial 4-6 in. high, native of the Greater 

 Atlas Mountains. Leaves springing from 

 stout rootstocks, stalked, irregularly cut 

 into linear acute lobes. Flowers in spring, 

 pale yeUow, l-j-2 in. across, tipped with 

 purple, and blood-red at the very base 

 of the ray-florets. Disc deep yellow. 



Culture and Propagation. — This is an 

 excellent plant for warm and sheltered 

 parts of the rock garden. It grows best 

 in well-drained gritty loam and leaf 

 mould, and may be increased by division 

 in early autumn, so that the divided por- 

 tions will become well established before 

 winter sets in. 



C. cinerariEefolium. — A native of 

 Dalmatia with leaves pinnately cut into 

 lobed segments. Flowers in July and 

 August, solitary, IJ in. across, white, with 

 a yellow centre borne on stems a foot or 

 more high. The famous Dalnaatian in- 

 secticide powder is obtained from this 

 plant. 



Culture dc. as above for C. Cata- 

 nanche. 



C. coronarium (Crown Daisy). — A 

 charming and very showy annual 3-4 ft. 

 high, native of S. Europe, with leaves 

 twice piimately cut into lobed and toothed 

 segments. Flowers from July to Sep- 

 tember, bright yellow, 2-3 in. across on 

 long stalks. • 



Cultivation and selection have pro- 

 duced some charming double varieties,' 

 with white, orange, lemon, and sulphur- 

 yellow flowers. 



Culture and Propagation. — Exactly 

 the same as for C. carinatum above.
