D. annua [Calendulapliwialis). — Cape 

 Marigold. — A straggling green and purple 

 stemmed annual about 6-18 in. high, with 

 narrow oblong obovate sinuately lobed 

 leaves 2-3 in. long, and masses of flowers 

 2-3 in. across in July, pure white inside, 

 dull purple outside, with a yellow centre. 

 They open well only in fine weather, 

 closing during rain and early in the 

 afternoon. There is a double-flowered 

 form caHeAflore plena. 



Culture dc. as above. 



D. Ecklonis. — A pretty species 1-1'. 

 ft. high, with oblong lance-shaped leaves 

 4-6 in. long, with a few large, irregular, 

 triangular teeth on the margins. Flowers 

 in June and July, pure white within, dull 

 purple outside, about 3 in. across, open- 

 ing only in bright sunny weather ; when 

 closed the ray florets are spirally twisted. 



Culture do. as above. 



CALENDULA (Marigold). — A 

 genus with about 20 species of aimual or 

 perennial, somewhat downy herbs with 

 alternate entire or sinuate toothed 

 leaves. Involucre broad. Disc flat, 

 naked. Pappus none. 



C. officinalis. — A showy strong- 

 smelling annual native of S. Europe, 9-12 



Tribe X. Arctotidb^. — Leaves radical or alternate. Achenes often fleshy, 

 smooth or with a chaffy pappus. Bracts of the involucre in many rows, often 

 searious or spinescent at the apex. Disc naked, chaffy, jpitted or hollowed. 

 Flowers rayed. 



in. high, with oblong sessile ciliated leaves. 

 Flowers in summer and autumn, orange- 

 yeUow, with a darker centre. The vari- 

 eties mentioned below, as well as La 

 Beine and Le Proust, are all fine double 

 ones. The variety prolifera is a Hen- 

 and-Chickens form, in which 8 or 9 

 smaller single flower-heads radiate from 

 the base of a larger central double 

 flower. 



Culture and Propagation. — Everyone 

 knows how easUy grown the Common 

 Garden Marigold is. The seeds are 

 sown in April or May, in any ordinary 

 soil in sunny or half-shady places. They 

 germinate freely and may be thinned 

 out about 1 ft. apart. Year after year 

 they wiU appear with regularity, and in 

 ever-increasing masses unless thinned 

 out. The choicer varieties, like Meteor, 

 Orange Cockade, and Orange King, are 

 improvements upon the common form 

 described above. For French and African 

 Marigolds, see Tagetes (p. 525). 



C. sufTruticosa. — A bushy Algerian 

 annual, softly downy and with a some- 

 what straggling habit. Leaves narrow, 

 almost entire. Flowers smaller than 

 those of the ordinary Marigold, but very 

 numerous, and bright yellow. 



Cultiire d-c. as above for C. officinalis. 



URSINIA (Sphbnogyne). — A genus 

 containing over 50 species of smooth or 

 rarely downy annual or perennial herbs or 

 bushes. Leaves alternate, serrate, pinna- 

 tifid, or often pinnately dissected. Flower- 

 heads at the ends of the branches usually 

 long-Stalked, soUtary, or in loose panicles. 

 Involucre hemispherical, or broadly bell- 

 shaped. Disc flat or convex, chaffy. 



Culture and Propagation. — Ursinias 

 grow in any ordinary light soil, and are 

 iiseful in masses in borders or beds in 

 snnny places. The kinds mentioned 

 below are best treated as half-hardy 

 annuals, and may be raised from seeds 

 sown in gentle heat about February or 

 March, and planted out at the beginning 

 of June, 12-18 in. apart. 



Seedlings from seeds sown in Septem- 

 ber may be wintered in cold frames or 

 greenhouses, but they are scarcely worth 

 6 months' care. 



U. anthemoides {Arctntis anthemoi- 

 des). — A S. Afiican annual 3-12 in. high, 

 with finely divided leaves and yellow 

 Marguerite-like flowers in August, the ray 

 florets being tinged with purple outside. 



Culture dr. as above. 



U. pulchra (Sphenogyne speciosa). — 

 A pretty annual, probably native of S. 

 Africa, 9-18 in. high. Leaves sessile, 

 pinnate, with linear acute segments. 

 Flowers in summer, 2-3 in. across, bright 

 yeUow, with a deep purple-black zone at 

 the base of the lance-shaped ray florets. 

 The variety aurea has a wholly yellow 

 centre, and there is also a pale sulphur 

 coloured form called sulplun-ra. 



Culture dc. as above. 



HAPLOCARPHA.— A smaU genus 

 of almost stemless peremiials with radical 

 entire or too bed leaves covered with 

 hoary wool or down on the under surface.
