CHEIRANTHUS 



CHENOPODIUM 



and innumerable forms in various shades of yellow, 

 brownish, and even purple. Not prized so much in 

 Amer. as in Eu. A common plant on walls in England. 



alpinus, Linn. St. strict and simple, 1 ft.: Ivs. 

 lanceolate, somewhat dentate, stellate-pubescent: pods 

 spreading on short pedicels: fls. lemon-yellow, spring. 

 Norway, Lapland. 



mutabilis, L'Her. More or less woody, 2-3 ft.: Ivs. 

 linear-lanceolate and pointed, obscurely serrate: fls. 

 white, cream-colored or yellowish, becoming darker and 

 striped. Madeira. B.M. 195. It is doubtful whether 

 the plant known in cult, as C. mutabilis is this species. 



Mdrshallii, Hort. Perhaps a hybrid, 1-1 ^ ft.: Ivs. 

 spatulate and crowded below, more scattered and 

 narrower above: fls. orange. 



Allionii, Hort. Said to be a hybrid: 12 in. or less: 

 fls. brilliant orange, profusely produced in spring and 

 summer and sometimes so freely that the plant exhausts 

 itself and becomes practically biennial. 



kewensis, Hort., is valuable as a winter-blooming 

 greenhouse plant, prized for its fragrance and its dark- 

 colored fls. In 1897 at Kew a cross was made between 

 C. mutabilis of the Canary Isls. and a yellow wall- 

 flower, the cross being known as C. hybridus; and this 

 in turn was crossed with a red wallflower, producing 

 the plant known as C. kewensis. It has the bushy char- 

 acter of C. mutabilis; racemes upright; fls. about 1 in. 

 across, brown in bud, or expanding brownish orange 

 inside and reddish brown outside, all turning pale 

 purple with age. Prop, by cuttings. G.C. III. 35:123. 

 Gn. 65, p. 89. 



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

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

 & Hook.=Parrya. L H B 



902. Chelone glabra. ( X l /i) 



CHELIDONIUM (Greek for the swallow: the fls. 

 appear when the swallow comes). Papaveracese. CEL- 

 ANDINE POPPY. One or two loose-growing herbs, some- 

 times seen in old gardens. Plant with fl.-buds nodding, 

 and small yellow fls. in small umbel-like clusters; 

 sepals 2; petals 4; stamens 16-24; style very short, the 



stigma 2-lobed: pod slender, 2-valved, opening first 

 at the bottom. C. majus, 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 

 sts. and pinnately-parted Ivs., the lobes rounded and 

 toothed (or, in var. laciniatum again dissected). The 

 plant has bright orange juice which has been used for 

 removing warts. Herb an old-time remedy, used for 

 its cathartic and diuretic properties, for promoting 

 perspiration, and as an expectorant. Lvs. fight glau- 

 cous underneath. L H B 



CHELONE (Greek for tortoise or turtle: the corolla 

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

 TURTLE -HEAD. Several North American perennial 

 herbs, with showy flowers in short spikes or in panicles, 

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

 Allied to Pentstemon. 



Upright smooth branching plants: corolla more or 

 less 2-lipped or gaping, white or red, the upper lip 

 arched and conspicuous and notched; anthers 4, woolly, 

 and a rudiment of a fifth stamen: seeds winged: Ivs. 

 opposite, serrate. Four species, in N. Amer. 



Half-shaded places are preferable for these easily 

 cultivated plants. Very dry grounds 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: 4-5 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. (J. B. Keller.) 



A. Fls. in terminal and axillary close spikes. 

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

 Lyonii, Pursh. Plant, 2-3 ft. high: Ivs. broad to 

 nearly cordate at base, thin, evenly serrate: fl.-bracts 

 minutely ciliate: fls. rose-purple. Mts., Va. and S. 



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



obliqua, Linn. Two ft. or less: Ivs. 2-8 in. long, 

 broad-lanceolate or oblong, very veiny, sharp- or deep- 

 serrate or cut: fl.-bracts ciliate: fls. deep rose. Damp 

 grounds, 111., Va., S. 



glabra, Linn. (C. obliqua var. alba, Hort.). Fig. 902. 

 One to 2 or more ft. high, more strict: Ivs. mostly nar- 

 rower, acuminate, appressed-serrate, nearly sessile, not 

 very veiny: fl.-bracts not ciliate: fls. white or rose- 

 tinged. Wet grounds: common. 



AA. Fls. in a loose thyrse or panicle. 

 nemordsa, Douglas (Pentstemon nemordsus, Trautv.). 

 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-purple. Calif, and N. 

 B.R. 1211. 



C. barbata of gardens is Pentstemon barbatus. L H B 



CHENILLE PLANT. A proposed name for Acalypha 

 hispida, better known as A. Sanderi. 



CHENOPODIUM (goosefoot, alluding to the shape of 

 the leaves). Chenopodiacese. GOOSEFOOT. Widely dis- 

 persed weedy herbs, with very inconspicuous greenish 

 flowers, some of which occur in gardens as oddities or for 

 ornament, and others are pot-herbs of very minor 

 importance. Spinach, beet, and orach are allied plants. 



Plants of various habit, mostly erect: fls. perfect, 

 bractless, sessile in small masses and these clusters 

 arranged in spikes or panicles; calyx 4-5-parted, petals 

 wanting; stamens usually 5; styles 2 or 3.: seed lentic- 

 ular: Ivs. alternate. The calyx sometimes enlarges 

 and becomes succulent and colored, inclosing the fr., 

 and the glomerules may then look like berries. Per- 

 haps 60 species in all parts of the globe, annuals and 

 perennials, sometimes woody. Many of them are 

 field and garden weeds. They are mostly mealy or
