CHRYSOGONUM 



heads being solitary and peduncled in the axils. Lys. 

 ovate and mostly obtuse, crenate. Prop, by creeping 

 rootstocks and runners. Of little merit horticulturally. 



CHEYSOPHt'LLUM (Greek, golden leaf, in reference 

 to the color of the under surface of the handsome leaves ) . 

 SapotAcea. Many species of trees, with milky juice, 

 widely distributed in the tropics. Fls. small, solitary at 

 the nodes or in fascicles; calj-x mostly 5-parted; corolla 

 tubular-campanulate, usually 5-lobed or -parted ; sta- 

 mens 5, standing on the corolla tube : fr. usually fleshy, 

 sometimes edible. C. Cainlto, Linn., is the Star Apple, 

 Pig. 409. The fruit is the size of an apple, symmetrically 



globular and smooth. A cross-section shows the star- 

 shaped core, whence the common name. It varies from 

 white to purple in color of skin and also of flesh. The 

 pulp is drlii-ious (usc-d uiiconkrd I if thf fniit is allowed

 properly protected. Propagation i- iir.|iii:iiil\ < nVcted 

 by seeds, which readily germinate if jilantc-.l wli. n fresh, 

 and it is stated that all species may be grown from cut- 

 tings of well-ripened shoots placed in strong, moist heat. 

 The soil most suited for their growth is of a sandy char- 

 acter, and if not of a good quality should be well manured, 

 using a considerable proportion of potash in the fertilizer 

 for fruiting specimens. They seem to do well on a 

 great variety of soils, however, that are sufficiently well 

 drained, wet land not agreeing with them. 



E. N. Reasoner and L. H. B. 

 CHBYSOPOGON (golden beard), iframinem. Very 

 like Andropogon, with which some authors unite it : 

 differs in having spikelets in pairs (or sometimes in 3's), 

 the lateral ones stalked and sterile or often reduced to 

 mere pedicels, only the middle or terminal one fertile. 

 C. nitans, Benth. {Andropdgon avendceus, Michx.), is in 

 the trade. It is native on dry soils in the eastern U. S., 

 growing 2-5 ft. high : perennial : culm unbranched, 

 terete: lvs. glaucous and narrow, short: panicle narrow, 

 with nodding, shining yellowish spikelets. Useful for 

 the wild border. L. H. B.

CHKYS6PSIS [golden appearance, 'trom the heads). 

 Compdsitce. Allied to Solidago and Erigeron; N. Ameri- 

 can. Heads of medium size and many-fld., usually with 

 numerous yellow rays ; involucre bell-shaped or hemi- 

 spherical, of imbricated bracts : akenes compressed, 

 bearing a pappus of numerous hair-like bristles. C. vil- 

 losa, Nutt., is the only species in the trade. It is widely 

 di.stributed from 111. W., N. and S. : 1-2 ft., grayish 

 pubescent : lvs, oblong to lanceolate, entire or few- 

 toothed : heads usually at the ends of leafy branches, 

 aster-like in shape. Extremely variable, and has several 

 named forms. Mn. 7:101. Var. Riitteri, Rothr., is larger 

 and later. Of value as a border plant. Cult, the same 

 as Aster. Perennials, but bloom the first year from 

 seed, if sown early. l. h. B. 



CHRYSOSPLfiNIUM AMEEICANUM, Schw. (name 

 from r/oldun and spleen, referring to some old medicinal 

 tradition). StiJ-ifragdceo'. A native plant creeping 

 in mud, which is sold for bog-planting. Stems fork- 

 ing, bearing roundish or cordate small mostly opposite 

 lvs., with very small, nearly sessile, greenish, incon- 

 spicuous fls. Scarcely known in cult.
