HEDYSARUM 



HELENIUM 



are of easiest cult, in a light and open, well-drained soil. 

 Give a sunny place; hardy. Prop, by division and seeds. 

 For the sainfoin, sometimes known as H. Onobrychis, 

 see Onobrychis. 



A. Fls. normally red (varying to white). 

 coronarium, Linn. FRENCH HONEYSUCKLE. Peren- 

 nial or biennial, 2-4 ft. tall, branchy: an old garden 

 plant with deep red, fragrant fls., crowded in axillary 

 spikes or racemes: Ivs. with 3-7 pairs of elliptic or 

 roundish, somewhat pubescent Ifts. Eu. Summer. 

 Var. album, Hort., has white fls. H. humile, Linn., is 

 by some regarded as a form of this species, with rather 

 more and narrower Ifts., and wings only half as long as 

 the keel. 



AA. Fls. normally purple (varying to white). 



multiiugum, Maxim. Hardy perennial of angular, 

 straggling growth, 2-5 ft. high, very showy, and worthy 

 of general cult.: fls. violet or purplish magenta, with 

 yellow blotches, in racemes 8-18 in. long, all summer: 

 Ivs. 4-6 in. long, containing 6-12 pairs of grayish green 

 oval, small Ifts. Mongolia. Gn. 53:408. G.C. III. 

 18:8, 9. Excellent for rockwork. Var. apiculatum, 

 Sprague, has fewer Ifts., which are apiculate, and gla- 

 brous above: perhaps the plant cult, as H. multijugum.

boreale, Nutt. (H. americanum, Brit.). Erect or 

 half -decumbent herb: sts. simple or nearly so, 1-3 ft.: 

 Ifts. 5-10 pairs, glabrous, oblong or oblanceolate : fls. 

 violet-purple, varying to white, the calyx-teeth ovate- 

 acute and shorter than the tube. Labrador and N. 

 New England across the continent. 



Mackenzii, Richards. Much like the last, but some- 

 what pubescent: fls. larger, violet-purple; calyx-teeth 

 awl-like and acuminate, and longer than the tube, or 

 at least equaling it: Ifts. 5-9 pairs. Colo., north and 

 west. 



sibiricum, Poir. Height 3-4 ft. : Ifts. ovate-lanceolate, 

 glabrous, apiculate: fls. purple, drooping in long axillary 

 racemes. Siberia. B.M. 2213 (as H. alpinum). 



obscurum, Linn. (H. neglectum, Ledeb.). Small, 

 usually about 6-12 in. high: Ifts. 5-9 pairs, ovate, 

 glabrous : fls . purple, pendulous in long spikes. Eu . B.M. 

 282. It is said to vary to white. L. jj_ g_ 



HEDYSCEPE (Greek, sweet covering). Palmaceae, 

 tribe Arecex. UMBRELLA PALM. A tall hothouse 

 palm known to the trade as a Kentia, and resembling 

 that genus in habit and foliage, but distinct in flower. 



In Kentia the fls. are arranged in 4 ranks, and the 

 ovule is fastened at the bottom of the cell, while in 

 Hedyscepe (and its cult, allies, Kentiopsis, Veitchia, 

 Nenga, Archontophcenix, Rhopalostylis and Dictyo- 

 sperma) the fls. are spirally arranged in the branches of 

 the spadix, and the ovule is fastened at the side. From 

 the allies above mentioned Hedyscepe is distinguished 

 by the following characters: staminate fls. with nar- 

 rowly lanceolate sepals, 9-12 stamens, with long 

 filaments; pistillate fls. with petals like the sepals and 

 yalvate at the apex. As a house plant, H. Canterburyana 

 is dwarf er and more spreading than the two howeas, and 

 has a lighter shade of green. G.C. II. 24:587. 



H. Canterburyana, a very handsome palm, is the only 

 species belonging to the genus, and, like the important 

 howeas (or kentias of commercial horticulture), is known 

 in a wild state only on Lord Howe's .Island, where it 

 is known as the "umbrella palm" from the recurving 

 habit of its foliage. It grows at a greater altitude than 

 the howeas, not appearing below the 900-feet level, and 

 from this it may be inferred that a slightly lower tem- 

 perature is more suitable for this palm; but in a general 

 way the same conditions as those required by the so- 

 called kentias will give good results with this subject, 

 namely, a night temperature of 60 to 62 F., moderate 

 shading throughout nearly the whole year, plenty of 



water, and a rich and rather heavy soil. These palms 

 respond freely to generous treatment. As a commercial 

 palm, H. Canterburyana is not very popular as yet, 

 partly owing to the higher cost of seeds and the fre- 

 quently low percentage of germination, and partly 

 from the fact that in a young state this palm is by no 

 means a rapid grower. In regard to hardiness of foliage,

it is fully equal to the kentias, and for gracefulness and 

 symmetry of growth will compare favorably with any 

 of the commercial species. In southern California it 

 is cultivated outdoors. (W. H. Taplin.) 



Canterburyana, Wendl. & Drude (Kentia Canter- 

 buryana, F. Muell. Vektchia Canterburyana, Hort.) 

 UMBRELLA PALM. Fig. 1791 (adapted from Martius). 

 Tall, spineless palm, with a thick, stout caudex: Ivs. 

 terminal, dense, equally pinnatisect, the numerous 

 segms. linear-lanceolate, acuminate, the lower nerves 

 recurved at the base, rather remote from the margin; 

 rachis arched, recurving: spadix with a short peduncle, 

 and thickened, flexuose branches; areoles lax: fls. 

 medium: fr. ovoid, large. R.H. 1873, p. 218. F.R. 

 1:85. G. 2:418; 5:592; 16:414. G.W. 12, p. 207 (the 

 last four all as Kentia). N. TAYLOR.! 



HEERIA: Heterocentron. H. elegans: Schizocentron. 



HEIMIA (Geheimerath. Dr. Heim, Berlin, died 

 1834). Lythrdcese. Two shrubs of the New World, 

 differing from Decodon in the yellow mostly 6-merous 

 trimorphous fls. borne in spikes: stamens 10-18. 

 H. salicifolia, Link (Nesaea salicifolia, HBK.), native 

 from Mex. to Buenos Ayres, is offered abroad: sub- 

 shrub, about 5 ft.: Ivs. opposite or in 3's, or the upper 

 alternate, lanceolate and acute: fls. yellow, with obo- 

 vate petals. This is said to be prized as an antisyphiiitic 

 and for other purposes. L. jj. B. 



HELENI6PSIS: Heloniopsis. 



HELENIUM (possibly from Helenus, the son of 

 Priam, but there is no clear record of the application 

 of the name). Composite. SNEEZEWEED. Hardy 

 annual and perennial herbs, bearing yellow flowers 

 from early summer to late autumn; only the perennials 

 are in cultivation. 



Stem erect, usually branching above: Ivs. alternate, 

 narrowly to broadly lanceolate, entire or toothed, 

 glandular-dotted; the frequently decurrent petiole and 

 st. sometimes winged: heads solitary or corymbose, 

 yellow or brownish; disk-fls. perfect, fertile, their 

 corollas 4-5-toothed; the ray-fls. pistillate or neutral, 

 the rays wedge-shaped, 3-5-lobed. About 30 species, 

 N. Amer., Mex. Closely resembles Helianthus, but dif- 

 fers in having elongated, often top-shaped frs., which 

 are never compressed and are usually silky villose; while
