CHEILANTHES 



CHENOPODIUM 



DDD. Lvs. covered beneath with both scales and wool. 



myriophylla, Desv. (G. elegans, Desv.). Lvs. densely 

 cespitose from short, erect, scaly rootstocks, 3-9 in. 

 long, beside the chestnut-colored scaly stems ; tri- 

 quadripinnatifld : ultimate segments minute, innumer- 

 able. Tex., Ariz, and Trop. Amer. 



Another native species worthy of cultivation is C. 

 leucopbda, Link, from Tex., with broadly deltoid-ovate 

 leaves. L. M. UNDERWOOD. 



CHEIEANTHUS (derivation in dispute, but probably 

 from Greek for hand and flower}. Cruciferce. A dozen 

 or more Old World herbs, with large purple or yellow 



fls., entire Ivs., and a strict or upright habit. Lateral 

 sepals sac-like at the base : valves of the pod with a 

 strong midnerve. Much confounded with Matthiola, and 

 the genera are not sufficiently distinct. In Cheiranthus, 

 the Ivs. are acute, stigma more spreading, pod more 

 flattened and seeds not thin-edged. 



Cneiri, Linn. WALLFLOWER. Fig. 424. Perennial, 

 slightly pubescent, 1-2% ft. : Ivs. lanceolate and entire, 

 acute : fls. large, mostly in shades of yellow, in long, 

 terminal racemes. S. Eu. An old garden favorite, 

 blooming in spring. Although a woody perennial, it is 

 best to renew the plants from seed, for they begin to 

 fail after having bloomed one or two years. Seedlings 

 should bloom the second vear. There are dwarf and 



double-fld. varieties, and innumerable forms in various 

 shades of yellow, brownish, and even purple. Not 

 prized so much in Amer. as in Eu. It thrives in any 

 good garden soil. 



C. dnnuus, Hort.=Matthiola, but early-blooming forms of 

 C. Cheiri seem to pass under this name. C. Menziesii, Benth. 

 & Hook.=Parrya. j^ H. B. 



CHELIDdNIUM (Greek for the swallow: the fls. 

 appear when the swallow comes). Papaveracece. CEL- 

 ANDINE. One or two loose-growing herbs, with fl.-buds 

 nodding, and small yellow fls. in small umbel-like clus- 

 ters : sepals 2 ; petals 4 ; stamens 16-24 : style very 

 short, the stigma 2-lobed ; pod slender, 2-valved, open- 

 ing first at the bottom. C. ma jus, Linn., is a European 

 plant, now run wild in waste places, and often seen in 

 old gardens. It is biennial or perennial, with brittle, 

 hairy stems and pinnately-parted Ivs., the lobes rounded 

 and toothed (or, in var. lacinidttim again dissected). 

 The plant has yellow juice. Lvs. light-glaucous under- 

 neath. 



CHELONE (Greek for tortoise or turtle: the corolla 

 fancied to resemble a reptile's head). Scrophularidcece. 

 TURTLE HEAD. Several North American perennial herbs, 

 some of which are now sold by dealers in native plants. 

 Allied to Pentstemon. Corolla more or less 2-lipped or 

 gaping, white or red: anthers 4, woolly, and a rudiment 

 of a fifth stamen : seeds winged: Ivs. opposite, serrate: 

 fls. large and showy. Half-shaded places are preferable 

 for these easily cultivated plants. Very dry ground should 

 be avoided, from the fact that they are best in swampy 

 places. In the ordinary border they should have a very 

 liberal mulch of old manure in their growing season : 4 

 to 5 in. thick is none too much ; the surface roots will 

 feed in this compost, and the plants are not so liable to 

 suffer from drought when thus protected. 



A. fls. in terminal and axillary close spikes. 



B. Lvs. broad-ovate, long-petioled. 

 Lyoni, Pursh. Plant, about 2 ft. high: Ivs. often cor- 

 date at base, thin, evenly serrate : fl. -bracts minutely cili- 

 ate; fls. rose-purple. Mts., N. Car. and S. 



BB. Lvs. lanceolate or oblong, short-petioled. 

 obliqua, Linn. Two ft. or less: Ivs. 2-5 in. long, broad- 

 lanceolate or oblong, very veiny, sharp- or deep-serrate : 

 fl. -bracts ciliate: fls. deep rose. Damp grounds, 111. and 



\ tl. ? O 



glabra, Linn. (C. obliqua, var. dlba, Hort.). Une-2 

 or more ft. high : Ivs. narrower, acuminate, appressed- 

 serrate, nearly sessile, not very veiny: fl.-bracts not 

 ciliate : fls. white or rose-tinged. Wet grounds ; com- 

 mon. 



AA. Fls. in a loose thyrse or panicle. 



nemorosa, Dough. Two ft. or less high, of unpleasant 

 odor : Ivs. ovate and acute, sharp-dentate, sessile or 

 nearly so: fl.-bracts none; corolla 1 in. long, violet-pur- 

 ple. Calif, and N. 



C. barbata of gardens is Pentstemon barbatus.

CHENILLE PLANT. A proposed name forAcalypha 

 hispida, better known as A. Sanderi. 



CHENOPODIUM (goose-foot, alluding to the shape of 

 the Ivs.). Chenopodiacece. Widely dispersed weedy 

 herbs, with very inconspicuous greenish fls. in glome- 

 rules'' or spikes. Spinach, beet, and orach are allied 

 plants. Fls. perfect; calyx 4-5-parted; petals wanting; 

 stamens usually 5; styles 2 or 3. The calyx sometimes 

 enlarges and becomes succulent and colored, enclosing 

 the fr., and the glomerules may then look like berries, 

 as in the common Strawberry Blite ( C. cap itatum, Wats., 

 or Blitum cap itatum, Linn.). This plant has been in- 

 troduced to the trade as a pot-herb. It is an annual of 

 easiest culture, with hastate-ovate toothed Ivs. and 

 fleshy red glomerules. The common pigweeds are 

 Chenopodiums of several kinds, the commonest being 

 C. album, Linn. This species and others are used as 

 pot-herbs or greens in the country. The Good-King- 

 Henry is C. Bonus-Henricus, Linn. It is a perennial, 

 of ten cult, for its succulent spring shoots and Ivs., which
