18. Leuc&nthemum, Linn. Ox-ete Daisy. White- 

 weed. Fig. 467- Glabrous weed, 1-2 ft. high : root-lvs. 

 long-petloled, with a large, oval blade and coarse, 



rounded notches; stem- 

 Ivs. lanceolate, becom- 

 ing narrower toward 

 the top, serrate, with 

 few distant and sharp- 

 er teeth. June, July. 

 Eu., N. Asia.— One of 

 the commonest weeds 

 in the eastern states, 

 being the characteristic 

 plant of New England's 

 womout meadows. 

 The daisies are never 

 cultivated, but they 

 are often gathered for 

 decoration, and make 

 excellent cut-flowers. 

 See, also, Daisy.

19. tndicum, Linn. 

 (C t/ap dnicum , 

 Thunb. ) . The wQd 

 plants native to China 

 and Japan are dwarfer 

 than C morifolium, 

 with Ivs. thinner, more 

 sharply cut, and green 

 on both sides, not glau- 

 cous: involucral scales 

 with wider and more 

 soarious margins : no 

 467. Ox-eye Daisy, or Whiteweed. chaff- fls. smaller, nu- 

 Whrvsanthemum Leucanthemum.) me^rous, and with rays 



always yellow ana 

 short, not much longer than the involucre. For pictures 

 of wild plants, see G. C. III. 8:565 and G. M. 33:729.— 

 Neither this species nor the next grows wild in India, 

 and the name given by Linnasus was inappropriate. 

 This species has varied greatly in cultivation, and its 

 progeny has been hybridized with that of O. ynorifolium. 

 Neither species in its pure form is in cultivation. Un- 

 fortunately, it is not possible to definitely trace the 

 origin of any of the main horticultural types, races or 

 sections. See historical sketch above. C. Indieum. is 

 often used in Germany in a wide sense, including O. 

 Sinense. 



20. morildlium, Eamatuelle (C. Sin^itse, Sabine). The 

 wild plants in Japan and China are more robust than C. 

 Indicwn. 2-4 ft. high, more or less tomentose, with 

 very variable Ivs., which are usually ovate in outline, 

 simiately cut and lobed, thick, firm, leathery, long-peti- 

 oled, and glaucous beneath: fls. larger and fewer, with 

 rays never (?) yellow; involucral scales with narrower 

 scarious margins: chaff present on the disk. — This spe- 

 cies was founded upon a cultivated and double form, and 

 fhere have been different opinions as to the original 

 wild progenitor. The above definition is an enlargement 

 of Hemsley's, in G.C. III. 6: 522. B.M. 327 (erroneously 

 named O. Indicum). Fig. 468 is the original double 

 purple-flowered, partly quilled variety, on which Eama- 

 tuelle, in 1792, founded the species C morifolium. 



C. inoddrum., LinTi.=Matricaria inodofa. W. M. 



CHRTSOBACTBON (golden wand, from the Greek). 

 Lili&ceoe. Two New Zealand bulbs, bearing many small 

 yellow fls. in a long raceme on the top of an elongated 

 scape. Plant often dioecious. Very closely allied to 

 Anthericura, with which Baker unites it, whereas 

 Bentham & Hooker refer it to Bulbinella. C. Hodkeri, 

 Colenso, is in cult, in this country. It is a hardy plant 

 2-3 ft. high, with sword-like foliage. B.M. 4602. -Cult. 

 in the ordinary border, and treated like the Asphodel, 

 they do well, but are vastly improved in rich, deep and 



rather moist soil. Strong clumps, 4-6 years old, are 

 then at their best and are very excellent plants. After 

 that they should be divided. Prop, by division or seed. 

 Blooms in June and July. j. b. Keller and L. H. B. 



CHBYSOBALAN'TTS (golden aeorn, from the Greek, 

 referring to the fruit). JBos&eeee. Two species in the 

 warm parts of Amer. and Afr. The Coooa Plum, C. 

 Ic&co, Linn., grows on coasts and along streams in S. 

 Fla., in south to S. Amer., and also in Afr. It is some- 

 times planted in the extreme south (and in the tropics) 

 as an ornamental shrub and for its sweetish but insipid 

 and dry plum-shaped fruits. The Cocoa Plum is a mere 

 bush on the northern limits of its distribution, but in 

 extreme S. Fla. it reaches a height of 25-30 ft. It has 

 glossy, thick obovate (sometimes obcordate) Ivs,: fls. 

 small and white, in axillary, erect racemes or cymes ; 

 calyx 5-cleft, pubescent ; petals 5 ; stamens about 20 : 

 fr. 1-seeded, often 1 in. in diam., varying from nearly 

 white to almost black. It is best propagated by seeds, 

 but may also be had from cuttings of half -ripened wood.

CHEYSOGONUM (Greek-made name, golden knee or 

 joint). Oomp6sit(e. C. Virginitlnum, Linn., is a peren- 

 nial yellow-fld. plant of S. Penu. and south, which is 

 sometimes cult, as a border plant. It blooms in spring 

 or early summer on stems which become 1 ft. high, the
