ing among other American plants, and re¬ 
quire similar treatment. Increased by 
layers. 
GENISTA (Lama.hck.) Nat. Ord. 
Leguminosee. The hardy species of genista 
are low deciduous shrubs, with yellow 
flowers copiously produced, and desirable 
in the fronts of shrubberies, because of 
their compact growth, and the contrast 
afforded by their glaucous foliage among 
others of a deeper and brighter green. 
They grow in common soil, and are readily 
increased by seeds, cuttings, or layers. 
Trained with an upright stem to what is 
called half-standard height, several of the 
species form handsome specimens to plant 
singly. 
GLEDITSCHIA (Linn.) Nat. Ord. 
Leguminosee . This genus is composed, 
with one exception, of large deciduous 
trees, resembling the common acacia in 
foliage and general habit; their flowers, 
however, are less beautiful, being green, 
and the branches are armed with large 
thorns, which are very hard and sharp- 
pointed : those on G. horrida are near 
three inches long, and have lateral spines 
equally strong and sharp. G. triacan¬ 
thus, the honey-locust tree, and G. mono- 
sperma, the swamp-locust tree, attain a 
height of thirty feet, and are very orna¬ 
mental in plantations; G. horrida is of 
smaller growth, and may be admitted for 
variety into the dressed portion of the 
garden. All of them succeed in ordinary 
soil, and are rapid growers; they, are 
usually raised from seed, but as this is 
seldom perfected in this country, we 
have to depend upon importations; graft¬ 
ing upon the acacia is also resorted to 
with success. 
GORDONIA (Ellis.) Nat. Ord. 
Ternstromiaceee. There are two species 
of Gordonia which, with some care, may 
be had to grow and flower in the open 
air, they are G. Franldini and Lasianthus, 
natives of North America, with bright 
green ample foliage, and elegant white 
flowers, resembling in form those of the 
almond. The plants should be stationer, 
in a bed of peat and loam, at the foot of 
a south wall, and in severe weather it 
may be necessary to cover them with a 
mat, in order to protect the young shoots. 
on which depends the next season s 
flowering; and to assist an early develop¬ 
ment and maturity, the ground about 
them should be well drained. Increase 
is had by layers or cuttings. May be 
struck under a handglass. 
GYMNQCLAHUS. (Lamauck.) Nat. 
Ord. Leguminosm. A strange-looking, 
scrambling shrub, with large pinnate 
leaves and white flowers; in summer it 
throws up a number of strong-growing, 
suckers and branches, almost denuded of 
leaves, and hence its name, which may be 
translated “naked stem.” These branches 
at first grow erect, but afterwards assume 
a subscandent character. It grows fast 
in any soil, and may be increased by 
division of the suckers, or cuttings of the 
roots. 
IIALESIA, Snow-drop tree. (Ellis.) 
Nat. Order. Fbenacene. The three 
species known to us are each hand¬ 
some flowering shrubs, remarkable for 
the number and purity of their snow- 
white blossoms, produced in .April and 
May. The flowers are borne in.clusters 
of six or eight together, at intervals 
along the branches, and resemble the 
common snow-drop; they appear before 
the leaves, and last two or three weeks, 
and are succeeded by winged drupes of 
rather large size. The plants succeed in 
common soil, of good quality, are quite 
hardy, and may be increased by cuttings 
of the roots. 
II ALIMOHENDRON (Eischeh) 
Nat. Ord. Leguminosee. A small genus 
of very handsome flowering shrubs, de¬ 
rived from the salt-fields of Siberia; there 
are three species, two of which were for¬ 
merly included in the genus Robinia, to 
which they are nearly allied. Their 
leaves are pinnate, the flowers copious, 
and a pleasing bright pink, produced in 
May and June. The plants thrive in 
common soil, and deserve a place in every 
garden. Increased by layers and grafting 
on the acacia. 
IIAMAMELIS, Witch Hazel. (Linn.) 
Nat. Order, Hamamelacere. These are 
spreading shrubs, which resemble the 
common hazel, but have bright yellow 
blossoms, appearing about the fall of the
