HELIPTERUM 



HELLEBORUS 



kinds are annual 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. 



Manglesii, Muell. (Rhoddnthe Mdnglesii, Lindl. Roc- 

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

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

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

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

 nally clear, handsome pink, but now varying to white 

 (R. dlba, Hort.), and to dark red (R. atrosanguinea, 

 Drumm.). Var. maculatum (R. maculata, Drumm. Roc- 

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

 larger,with shorter Ivs. 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 .Rhodanthe varius. 



BB. Lvs. linear. 

 rdseum, Benth. (Acro- 

 clinium rdseum, Hook. 

 Roccdrdia rbsea, Voss). 

 Fig. 1034. Annual, 1-2 ft. 

 high, glabrous, with many 

 strict simple branches 

 from the crown, each stem 

 terminated by one large 

 head: Ivs. numerous, al- 

 ternate, small and linear: 

 rays many, pointed, bright 



1034. Helipterum 

 roseum (X %). 



1035. Helipterum Humboldti- 

 anum 



i o, in H ' dlbu > Hor *. ) Austral. 



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



AA. Heads small, clustered. 



Humboldtianum, DC. (H. Sdnfordii,Kook. Roccdrdia 

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



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

 what branching : Ivs. (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. (Roccdrdia corymbiflbra, 

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

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

 corymbs, the prominent rays white. Australia.

HELLEBOKE. See Htlleborus. 



HELLEBORUS (ancient name of H. orientalis, mean- 

 ing unknown). Ranunculaceaz. Hardy herbaceous per- 

 ennials, about 8 species, natives of Europe and western 

 Asia. Erect, with large palmately divided Ivs., 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 boiders, 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. All 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-

A. Lvs. dying annually, thin. 



viridis, Linn. Stem scapose: rootstock creeping: 1 

 basal leaf 8-12 in. broad, on petiole 6-10 in. long; seg- 

 ments 7-11, oblong, acute, sharply serrate: fl.-stem 

 hardly exceeding the basal leaf, bearing 3-6 fls. and 

 large, leaf-like bracts: fls. large, yellowish green; se- 

 pals broadly oblong, obtuse, spreading: capsules about

 Not so much used as the other species here given. 



Var. purpurascens, Waldst. & Kit. Differs chiefly in
