HELIPTERUM 



kinds are aunual herbs (or grown as such), of easiest 

 cultivation in any garden soil. Fls. mostly perfect, with 

 5-toothed open corollas: akenes woolly, bearing a pap- 

 pus of many plumose bristles: involucre glabrous, obo- 

 vate or top-shaped, silvery or rose-colored: plants 

 mostly glabrous. This and Helichrysum are amongst 

 the most important of everlasting flowers. 

 A. Heads large, many-flowered. 

 B. Lvs. broad. 

 Hinglesii, Muell. {Bhoddnthe Mdnglesii, Lindl. Boc- 

 cdrdia Mdnglesii, Voss). Fig. 1033. Neat glaucous an- 

 nual, 12-18 in. tall, with very slender, long pedicels, 

 bearing pretty nodding heads: lvs. thin, oval or elliptic, 

 clasping: involucre silvery-chaify, the ray florets origi- 

 nally clear, handsome pink, but now varying to white 

 {R. dlha, Hort.), and to dark red (B. atrosanguivea', 

 Drumm.). Var. macuIAtum ( ii". mnciiM^n, Drumm. Boc- 

 cdrdia Mdnglesii, var. maeuldla, Voss), is usually 

 larger, with shorter lvs. and involucre flecked with red: 

 rays pink or white. Austral. B.R.20:1703. — A charm- 

 ing plant, and one of the few everlastings which retains 

 much of its grace and beauty after being dried. There 

 are double-fld. forms, i. e., those with all or nearly all 

 the florets ligulate. Excellent also for pot culture. 

 Seeds of the mixed vars. are sometimes sold under the 

 name Bhodanthe varius.

rdseum, Benth. (Acro- 

 cliniiim rdseum, Hook. 

 Boccdrdia rdsea, Vo.ss). 

 Fig. 1034. Annual, 1-3 ft. 

 high, glabrous, with many 

 strict simple branches 

 from the crown, each stem 

 terminated by one large 

 head: lvs. numerous, al- 

 ternate, small and linear: 

 rays many, pointed, bright 



pink (or varying to white in ff. dlium, Hort.). Austral. 

 B. M. 4801. — A very serviceable and handsome plant. 



AA. Heads small, clustered. 



Humboldtianum, DC. (H. Sdiifordii, Hook. Boccdrdia 



Humboldtidna , Voss). Fig. 1035. Annual (or cult, as 



HELLEBORUS 



such), erect or with a decumbent base, the stems some- 

 what branching: lvs. (and stems) white-tomentose, 

 linear or lance-linear, pointed, alternate: heads small, 

 oblong, yellow, in a dense corymbose truss. Australia. 

 B.M.5350. 



corymbifldrum, Schlecht. {Boccdrdia corymbiflora, 

 Voss). Annual, lower than the last, more branchy: lvs. 

 broader: heads 2-3 times larger, top-shaped, in small 

 corymbs, the prominent rays white. Australia. 



HELLEBORE, See Helleborus. 



HELLEBORUS (ancient name of H. orientalis, mean- 

 ing unknown). Ban line II I deed. Hardy herbaceous per- 

 ennials, about 8 species, natives of Europe and western 

 Asia. Erect, with large palmately divided lvs., the ba- 

 sal long-petioled, the upper sessile and sometimes re- 

 duced to bracts: fls. large, white, greenish, red, purple, 

 or yellowish; sepals 5, broad, petal-like, mainly persis- 

 tent; petals small, tubular, furnished with claws; sta- 

 mens many ; carpels 3-10, sessile, forming leathery, 

 many-seeded capsules, dehiscent at the apex. 



All the kinds will thrive in ordinary garden soil, but 

 for the best results use a soil of rich loam and coarse 

 sand, with a top-dressing of rotten manure. A moist, 

 well-drained, partially shaded situation is preferable. 

 The species may be planted in shrubbery borders, and 

 in rockeries, or if wanted for cut-flowers they should be 

 planted in beds. An important point is not to disturb 

 the plants when once established, as they are very sen- 

 sitive to frequent changes of location. AH the species 

 bloom before spring arrives; a few mild days in Decem- 

 ber or January will bring out the buds of H. niger va- 

 rieties, and the others are not far behind. They are 

 easily forced under glass. Strong plants should be taken 

 up into large pots and gradually inured to a warm tem- 

 perature. Blossoms may thus be brought forth at any 

 time desired in winter. Prop, best by division in fall or 

 spring; but if seeds mature they will germinate well 

 if planted immediately in pans or in rich, open ground. 

 Seedlings should bear flowers the third season. Mono-
