Kentia. : 
(Viscount Canterbury’s).* fl., panicle branch- 
ing into spreading spikes of about 6in., the rachis thick and 
flexuose, the notches not immersed and not close ; male perianth, 
outer segments narrow-lanceolate, about two lines, the inner ones 
broader and striate ; female perianth, outer segments three lines 
broad, and almost as long, inner ones ovate and rather shorter. 
fr. ellipsoid, the pericarp hard when dry. J. long, pinnate, in a 
dense head; segments numerous, nearly equal, and acuminate.

Fig. 194. - 
HEEL. The base of a young cutting, when removed 
from the junction formed by its connection with the parent 
plant. Many cuttings, especially those of a hard-wooded 
nature, root better when inserted with Heels, that part of 
the wood being just sufficiently solidified ; and, if removed 
from the side of a branch, a larger surface is secured for 
placing in contact with soil than when a horizontal cut 
is made. 
HEELING-IN. The temporary insertion of cuttings, 
or the roots of plants, in soil, to preserve them until their 
permanent quarters are prepared. Heeling-in also applies 
to crops that are lifted, and their roots temporarily covered 
with soil in a cool situation, to prolong the season of 
supply. 
HEERIA (named in honour of Oswald Heer, a cele- 
brated Swiss botanist of the present century). Sywns. 
Heterocentron, Schizocentron. ORD. Melastomacee. A 
genus comprising about four species of erect or pros- 
trate, pilose or glabrous herbs and sub-shrubs, inhabit- 
ing the mountains of Mexico and Guatemala. Flowers 
white or pink; petals four, ovate or obovate, obtuse or 
acuminate. Leaves cordate, lanceolate, or obovate-lanceo- 
late, membranaceous. H. rosea, the only species yet 
introduced, is a very rare but ornamental stove ever- 
green shrub, which can be grown out of doors, in warm 
localities, during part of the summer. It is a valuable 
stove winter-flowering plant, and succeeds best in sandy 
loam and peat. Cuttings of young shoots may be struck 
in February and March. 
oota ol Uns gaara ————— 
corymb of many bright rose-coloured flowers, nearly lin. in 
diameter; petals four, spreading, rhomboid-orbicular, a little 
concave, shortly unguiculate. Autumn and early winter. J. 
opposite, slightly scabrous above, elliptical, obtuse, entire, penni- 
_nerved, tapering at the, base into a moderately lon, tiole. 
k. 1ft. or more. Mexico. Plantsuffruticose. (B. M. 5166, t under 
name of Heterocentrum mexicanum.) 
This genus is now included under Neswa 
H. Canter’ 
(which see). 
_HEINSIA (named after the -celebrated philologist, 
Heinsius, who translated the writings of Theophrastus), 
_ Opp. Rubiacew. A genus including three or four species 
< evergreen shrubs, natives of tropical Africa. Flowers 
White, largish, pedicellate, solitary, or disposed in three 
to six-flowered terminal cymes. Leaves opposite, shortly 
petiolate, oblong or elliptic-lanceolate, acuminate. H. 
jasminiflora, the only species yet introduced, is a beau- 
tiful, much-branched, unarmed, glabrous, stove shrub. 
æ (Jasmine-flowered).* fl. white, salver-shapen: 
yur together at the tops of the branchlets, 
racemose, February. l. opposite, oval-

cellate, in the axils of the leaves. Leaves entire, coriaceous. 
Probably the only species yet introduced is the one 
described below. It is a stove evergreen tree, thriving 
in a compost of loam, sand, and peat. Firm cuttings 
will root in sand, in brisk bottom heat. 
H. coccinea (scarlet). f. white, small, twin or numerous, 
axillary; calyx dark purple or scarlet. Winter. J. alternate, 
— lanceolate, rounded at the base. A. 15ft. West Indies, 
HELCIA. Included under Trichopilia (which see). 
HELENIUM (Helenion, an old Greek name used by 
Hippocrates, and probably derived from Helen of Troy). 
ORD. Composite. A genus containing about eighteen 
species of ornamental hardy herbaceous annuals or peren- 
nials, inhabiting Central and North America. Receptacle 
chaffy, between the ray-florets only; pappus of five 
bristles; involucral bracts in one series, united at the 
base; ray-florets toothed at the apex. Leaves alternate, 
often decurrent, entire or few-toothed. The species are 
more or less strong-growing, and are, consequently, best 
suited for the margins of shrubberies or the back of 
herbaceous borders. In such situations, they may be 
‘extensively grown, and the abundance of flowers which 
they produce will prove valuable for decorative purposes. 
Propagated by divisions, or by seed. 
H. autumnale (autumnal).* jl.-heads pure yellow, large, with 
long four to five-cut ray-florets. Autumn. Z. smooth, lanceolate, 
din, to 4in. long, żin. broad, acute at both ends. Stem branching 
attop. h. 4ft. to 6ft. North America, 1729, Perennial. A very 
showy and elegant species, (B. M. 2994.) 
H. Hoopesii (Hoopes’s). fl.-heads bright orange, about 2in. across; 
involucral segments long, narrow, acuminated. Summer, l. 
lanceolate, acuminated, smooth, stem-clasping. Stem simple. 
h. 2}ft. North America. Perennial. 
H, nudiflorum (naked-flowered). fl.-heads pure yellow, loosely: 
disposed, medium-sized, fragrant. Summer andautumn. 1. alter- 
nate, linear-lanceolate. h. 2ft. to 34ft. South Unitel States. 
Perennial. H. n, atropurpureum (dark purple) is a variety with 
purple ray-florets. 
H. quadridentatum (four-toothed). fl.-heads yellow; disk- 
florets four-toothed. May to October. Ñ, lower ones pinnatifid ; 
oper gyre smooth. Louisiana, 1790. Annual or biennial. 
HELIAMPHORA (from helios, the sun, and amphora, 
a pitcher; in reference to the circular ascidia). ORD. 
Sarraceniacew. A monotypic genus. The species is a 
greenhouse herbaceous perennial. Probably this plant 
only yet exists in a single establishment in this country. 
Most likely it requires similar treatment to Sarracenia 
(which see). í 
H. nutans (nodding). f. white, or pale rose-coloured, nodding, 
on an erect, few-flowered scape ; sepals five, rarely four, spreading. 
l radical, tubular, in the Drin of a pitcher with an oblique 
mouth, lined with deflexed hairs. h. lft. to 2ft. Roraima, 
1883. (T. L. S. xviii. 29.) 
HELIANTHEMUM (from helios, the sun, and anthe- 
mon, a flower). Sun Rose. Including Fumana. ORD. 
Cistinee. A genus of showy, hardy, annual or perennial 
herbs or sub-shrubs, often prostrate. Nearly 150 forms 
have been described as species; but, according to Bentham 
and Hooker, only about thirty are entitled to specific 
rank, They are natives of North, Central, and South 
America, and the Mediterranean region; a few extend 
to other parts of Europe and Western Asia, four species 
being members of the British Flora. Racemes secund, 
sometimes corymbose, sometimes paniculate; and before 
the flowers expand, the racemes at the top are bent or 
twisted backwards, becoming gradually erect as the 
flowers open. Leaves opposite and alternate. All the 
species are of easy culture in a sandy-loam soil, and 
are best adapted for banks and rockwork. The annual 
species must be raised from seed. The perennials 
may be similarly increased; but it is better to trust to 
cuttings, which root readily in a sandy soil, if kept 
shaded until established. The following is a selection. 
of the more important species and varieties.
