 petioled, upper ones almost sessile, the largest lvs. 5-11

 white rays, but when they are absent the plant is var.

 N. Afr.. W. A-iM. (ill. 18, p. 195. R.H. ISlir,, pp. 448, 

 449. — Var. grandiflorum, Hort., is a larRrr-tld. fimn of 

 this weed, which is .'(iiinnon in the English grain fields. 

 The var. Cloth of Gold, J.H. III. r2:445, is probably the 

 best. This species is much less popular thiui P. carina - 

 film and coromirium. It is also forced to a slight extent 

 forwinter bloom. "Segetum" means "of the corn fields." 



14. multicaCile, Desf. Glabrous and glaucous annual, 

 6-12 in. high : stems numerous, simple or branched, 

 stout, terete : lvs. fleshy, variable, usually linear- 

 spatulate, 1-3 in. long and %-^'i in. broad, very coarsely 

 toothed or lobed, sometimes shorter, with few narrow- 

 linear, acute, entire segments about 1 line broad : rays 

 much shorter and rounder than in No. l.*J. Algeria.

15. laciistre, Brot. (C. latifdlium, DC). Fig. 465. 

 This is endlessly confused with C. tnaximum in gar- 

 dens, and the two species are very variable and difficult 

 to distinguish. The fls. cannot be told apart. C. laeustre 

 is a taller and much more vigorous plant, and some- 

 times it is branched at the top, bearing 3 fls., while O. 

 maximum is always 1-fld. Height 3-6 ft. : stem sparsely 

 branched : lvs. partly clasping, ovate-lanceolate, with 

 coarse, hard teeth: fls. not distinguishable from No. 16: 

 rays about 1 in. long ; pappus of the ray 2-3-eared. 

 Portugal, along rivers, swamps and lakes. R.H. 1857, 

 p. 456. — According to R. Irwin Lynch, in Gn. 26, p. 441, 

 C, laeustre has coriaceous, oval lvs. about 3 times as 



long as broad, while in ('. iii'(.i iihiiih the lvs. are 5 times 

 as long as broad. H. Cmiiim II, Swaiilry. Eng., says that 

 C. laeustre is 2 ft. high an.l IiI.m.his :i weeks before C. 

 maximum. With Woolson, I'assaic, N. J., it grows 4-5 

 ft. high. The rays in Fig. 465 are rather shorter than 

 usual. 



16. m&ximam, Raraond. Fig. 466. This species has 

 narrower lvs. than No. 15, and they are narrowed at the 

 liase. Height 1 ft. ; stem more angled than the above, 

 simple or branched at the very base, always 1-fld. and 

 leafless for 3—4 in. below the fl. : lower lvs. petioled, 

 wedge-shaped at the base, lanceolate, dentate from the 

 middle to the apex; stem-lva. sessile, wide- or narrow- 

 lanceolate, typically serrate throughout their whole 

 len^'th, but variable, as in Fig. -U'ii\ : |i;i|ipus none : in- 

 volucral scales narrower and 1(>iiu^<-t-. w hiiish-transpa- 

 rent at the margin, while tliese of )'. hirustre are 

 broader, more rounded at the ai)ex, and with a light 

 tirown, scarious margin. Pyrenees. — For other pictures 

 of these two species, see J.H. III. 5:25, and Gn. 26, p. 437. 

 Var. {ilifdrmis, Hort., "with long, narrow, thread-like 

 petals." Int. 1899. Var. Triumpli has "fls. 4 in. across, 

 with broad, overlapping petals."

 coccineum, this is the most popular of the hardy herba- 

 ceous kinds. In A. F. 4; 405 Wm. Falconer shows a 2- 

 year-old plant 6 ft. high, 17 ft. in circumference at a 

 point 4 ft. from the ground, and carrying thousands of 

 flowers. It blooms the first year from seed or division, 

 and has been forced for Easter somewhat a>s Hydrangea 

 paniculala can be treated. Excellent for cut-fls. The 



466. Chrysanth' 



blossoms should be cut soon after opening, as the disks 

 darken with age. The plant needs a rich, moist soil, 

 and deserves a greater popularity. "Uliginosum " means 

 "inhabiting swampy places."
