HALESIA. 
Gypsoca’Luis, Sal.— Ericdcee.— 
The mbor, or Cornish Heath, sepa- 
rated from the genus Erica by Sal- 
isbury.—For culture, see Ert‘ca. 
Gypso'pHiLa. — Caryophyllacee, 
or Silendcee. — Small - flowered 
creeping or trailing plants, annuals 
and perennials, which require a 
calcareous soil, and are well adapt- 
ed for rockwork. 
Gypsum.—Sulphate of lime, com- 
monly called plaster of Paris. 
Guo Arabic Tree.—Acdcia vera, 
or arabica.—See Aca\cta. 
Gum Cistus.—Cistus Cy'prius, 
or ladaniferus—See Ci'stus. 
H. 
Hapena‘RIA. Orchidaceae. — 
Hardy North American perennials, 
with tuberous roots, and very curi- 
ously shaped flowers, which are 
generally yellow, but sometimes 
purple, and sometimes white. They 
grow best in a shady situation, and | 
in a peat soil, kept rather moist 
than dry. 
Hapra’ntuus. — Amaryllidacee. 
—Bulbous-rooted plants, (some of | 
which will thrive in the open ground, 
though others require a greenhouse, 
and others a stove,) the culture of 
which exactly resembles that of 
the Amaryllis. The flowers are 
also similar, though very much 
smaller; and, as in the Amaryllis, 
they are produced before the leaves. 
The Habranthus appears to exem- 
plify the doctrine of bulbs being | 
under-ground stems; for we are 
told by the Hon. and Rev. W. Her- 
bert, (Got. Mag. t. 257,) that the 
bulbs of this species, though round | 
when imported, after having been 
potted a year become gradually 
elongated. Plants of this genus are 
generally grown in a mixture of 
sandy loam and peat; and for the 
details of their culture, see Ams-| seed is curiously winged. 
RY’LLIs. 
Hema'ntuus.—Amaryllidacee.—- 
Bulbous plants, with large red flow- 
ers of very singular appearance and 
no particular beauty. They are 
very coarse-growing, and take up 
a great deal of room. H. multi- 
florus is, however, an exception, a9 
it is rather pretty. All the species 
require the heat of a greenhouse, 
and to be grown in sandy loam and 
peat ; they should also have a sea- 
son of complete rest. For the rest 
of their culture, see AMARY’LLIS. 
H zmato'xyLon.—-Leguminose.-— 
The Logwood. This tree, which 
grows about twenty feet high in its 
native country, is a stove-shrub in 
Britain, It has yellow flowers, and 
should be grown in a mixture of 
peat and loam. 
Ha‘xea.— Protedcee. — Austra- 
lian shrubs, with flowers somewhat 
resembling those of the Grevillea, 
which are frequently sweet-scented. 
The plants are generally kept in 
the greenhouse, should be grown in 
peat and sand mixed with a little 
loam, and the pots should be well 
drained, and never suffered to be- 
come either too wet or. too dry. See 
| AUSTRALIAN SHRUBS. 
Haxe'sis. — Halesidcee. — The 
| Snowdrop-tree. American low trees, 
|which generally form very hand- 
| some hardy shrubs in British pleas- 
ure-grounds. The reason of this 
lis, that in North America the 
species all grow on the banks of 
rivers, in very poor rocky soil, 
whereas in England they are grown 
|in dry places in rich soil; and too 
much nourishment to a tree which 
does not require it, has the same 
effect as too much animal food to a 
child—it makes it increase in width 
instead of height. ‘The Snowdrop- 
tree flowers freely, and its stem 
| droops gracefully over water. ‘The 
flowers are white, and resemble 
those of the Snowdrop; and the
