AN ENCYCLOPADIA 
OF HORTICULTURE 109 
Hematoxylon—continued. 
H. campechianum. Campeachy Wood. f. yellow, produced in 
axillary racemes. J. abruptly pinnate, in fascicles ; leaflets small, 
obovate, obcordate. A. 20ft. to 40ft. Central America, Columbia, 
and the West Indies, 1724. This plant yields the well-known 
logwood of commerce, largely pnpioyad by calico-printers, dyers, 
and hat-makers. Ft consists of the heart-wood of the tree, from 
which the sapwood has been removed, and is of a deep, dull, 
brownish-red colour, (B. M. Pl. 86.) 
HE MODORACEZ. An order of epigynous mono- 
cotyledons, belonging to Lindley’s Narcissal alliance of 
Perennial herbs, natives of the Cape, North 
and South America, Central and Eastern Asia, and South- 
west Australia. Perianth petaloid, tubular or sub-cam- 
panulate, usually hairy or woolly outside, glabrous within. 
Leaves alternate, usually distichous, sub-ensiform, sheath- 
ing at the base, equitant. Bitterness exists in some of 
the plants. The roots of some also yield a red colour: 
hence the name of the order. As understood in the 
“Genera Plantarum,” there are twenty-six genera and 
about 120 species. Well-known genera are: Anigo- 
santhus, Hemodorum, and Wachendorfia. 
HAMODORUM (from haima, blood, and doron, a 
gift; probably in reference to the roots serving as food 
for the natives of Australia. The name was given by 
Theophrastes to the Broom-rape). Bloodroot. ORD: 
Hemodoracee. A genus of about seventeen species of 
pretty greenhouse perennials, all natives of Australia, with 
black, red, livid green, or orange-coloured flowers. They 
thrive in peat and loam. Increased by dividing the 
roots, in spring. The two species described below are 
those best known to cultivation. 
H. planifolium (flat-leaved). fl. livid-purple or greenish at the 
base, in short forked racemes or cymes, collected in a compact, 
more or less corymbose panicle; perianth segments linear or 
linear-lanceolate. August. 1., lower ones grass-like, flat; ba 
ones few and short. Stems 2ft. to 3ft. high. 1810. (B. M. 1610.) 
H. teretifolium (terete-leaved). This closely resembles H. plani- 
folium, but the leaves are from a short sheathing base, very long, 
slender, and terete, or nearly so. August, 1822, 
HAGBERRY. Sce Cerasus Padus. 
HAIRBELL. See Harebell. 
HAIR GRASS. Se Aira. 
HAKEA (named after Baron Hake, a German patron 
of botany). Syn. Conchium. ORD. Proteacee. A large 
genus (ninety-five species have been described) of green- 
house evergreen shrubs or rarely small trees, limited to 
Australia. Flowers hermaphrodite, in pairs; perianth 
irregular or rarely regular, the tube revolute or curved 
under the limb, or rarely straight. Leaves alternate, very 
diversified in shape, flat or terete; margins rarely re- 
curved, and the two surfaces usually similar and equally 
veined. Hakeas thrive in a compost of two parts peat 
and one of loam, with sufficient sand to secure perfect 
drainage. Well-ripened cuttings will root in sandy peat, 
under a bell glass, if first placed in a cool house, and 
transferred to a mild bottom heat so soon as a callus 
is formed. During summer, when the plants are grow- 
ing, water may be freely given in early morning or 
—— at other times, it should be carefully adminis-

cacee. A genus containing about -a-dozen species 
ornamental hardy deciduous small trees, of which three 
are North American, one Chinese, and two or three 
from Japan. Flowers white, showy, drooping, on slender 
pedicels, in fascicles (or rarely very short racemes) from 
the axils of the fallen leaves of the preceding year. Leaves 
rather large, ovate-oblong, acuminate, more or less den- 
ticulate, slender-petioled. The species are well suited for 
shrubberies and lawns, in almost any position; but one 
somewhat sheltered is most suitable, and a deep, sandy, 
moist soil is best. Increased by layers, or by cuttings 
of the roots, in spring and autumn.
