mental tree, thriving in peat and loam, with a

Hkdychium, KSnig. From hedys, sweet, and chion, 
snow ; alluding to the sweet-scented snow-white 
flowers of some of the species. Linn. 1, Or. 1, Nat. 
Or. ScitamineoB. The species of Hedychium, or 
Garland Flower, are all highly -prized flowering 
plants, more particularly H. angustifolium and 
H. ceronarium ; they are all well worthy of exten- 
sive cultivation. They all grow freely in rich 
light soil, and to flower them well, they require a 
large pot, with a plentiful supply of water when 
in a growing state ; they are readily increased by 
dividing the roots. Synonymes : 1. angustifolium.

Hedysarum, Linn. From hedysaron, the name of a

Linn. 17, Or. 4, Nat. Or. Leguminosx. Almost all 
the species of this genus are very handsome flower- 
ing plants, producing racemes of very beautiful 
pea flowers, particularly adapted for flower- 
borders, or rock-work. They grow freely in a 
light rich soil, or loam and peat, and the herba- 
ceous kinds are increased by dividing the roots in 
spring, or by seeds. The seeds of the annual and 
biennial kinds only require sowing in the open 
border in spring. Synonyms: 1. H. sibiricum. 2.

Heimia, Link. In honour of Dr. Heim, a celebrated 
Berlin physician. Linxi. 11, Or. 1, Nat. Or. Ly- 
thracece. These plants are very pretty when m 
blossom ; they grow well in an equal mixture of 
loam and peat, with a little sand. They only 
require to be protected from frost in winter, which 
may easily be done if the plants are against a south 
wall ; if in pots, they should be removed into the 
greenhouse. Cuttings strike freely either in sand 
or soil, under a glass. Synonyms : 1. Nesaea salici-

Heisteria. Named by Linnaeus, in honour of 
Laurence Heister, once professor of botany at Helm-

Olacaceas. This is a tree which attains the height 
of about fifteen feet, and is cultivated in a mixture 
of loam, peat, and sand ; and cuttings will root in 
sand, under a glass, in heat. The wood of this 
tree is the partridge-wood of the cabinet-makers,

HelEnium, Linn. Named after the celebrated Helen. 
Linn. 19, Or. 2, Nat. Or. CompositiP. Very pretty 
tallish-growing plants, well adapted for flower- 
borders ; they will grow freely in any common 
garden soil. The herbaceous species may be in- 
creased by dividing the roots. The annuals and 
biennials require the same treatment as is generally 
given to such species.

HelianthEmCm, Toum^ort. From helios. sun, and

Linn. 13, Or. 1, Nat. Or. dstaceoe. This is a very 
showy, free-flowering genus of plants, comprising 
some of the prettiest little shrubs in cultivation, 
for ornamenting rock-work. In winter, some of 
the species require the protection of a frame, or 
greenhouse, and on that account, require to be 
grown in pots; they all thrive well in a mixture 
of sandy loam and peat. The shrubby kinds may 
be increased by cuttings, under a hand-glass, in a 
sheltered situation, or by seeds, by which the annual 
species are also to be raised. Synonymes: l.visci-
