CHRYSOGONUM 



heads being solitary and peduncled in the axils. Lvs. 

 ovate and mostly obtuse, crenate. Prop, by creeping 

 rootstocks and runners. Of little merit horticulturally. 



CHEYSOPHfLLUM (Greek, fifo/dew hiif, in reference 

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

 Sapoiacea. Many species of trees, with milky juice, 

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

 the nodes or in fascicles ; calyx 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, 

 Fig. 469. The fruit is the size of an apple, symmetrically

CHBYS6PSIS (golden appearance,' from 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- 

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

 distributed from 111. W., N. and S. : 1-2 ft., gravish 

 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. Biitteri, 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 AMERICANDM, Schw. (name 

 from ;/i-/(/i /( :uid sphvit, referring to some old medicinal 

 tradition). ,S'(ij//"cn(/(icffp. 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.

I.H. 32;0li7. A.U.ll:40.j. C. oliviSorme, Lam., is also in 

 the Amer. trade, but as au ornamental plant. It is a 

 smaller West Indian tree, native also in extreme S. Pla. 

 Lvs. like those of the last: stigma 5-crenate (in G. Cai- 

 nito 8-10-crenate) : fr. ovoid-oblong and small, 1-seeded, 

 blackish, insipid. These plants are allied to the Sapodillo. 



The various species of Chrysophyllum have beautiful 

 broad green leaves, ^ith under surfaces of a silky texture, 

 varying in color from a silvery white, through golden, to 



a russet brown, and are well worth a |ilarr in il ou-

 Apple of the West Indies, is edible, and well lik.-.l iven 

 by people of a temperate clime. All species are strictly 

 tropical, and cannot be grown where frosts occur unless 

 properly protected. Propagation is ordinarily effected 

 by seeds, which readily germinate if planted when 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.
