hes high, with narrow leaflets, and
terminal heads of yellow flowers produced in summer.

G. SAGITTALIS.--South Europe, 1750. With its peculiarly winged and
jointed stems, which are of a deep green colour, this is one of the most
distinct forms. The flowers are few but pretty, and with the dwarf habit
render the plant an excellent subject for rockwork.

G. TINCTORIA.--Dyers' Greenweed. Europe (Britain), North and West Asia.
This is a spineless species, and bears a profusion of yellow flowers
from July onwards. The double-flowering variety, G. tinctoria
flore-pleno, is, in so far as ornamental qualities are concerned,
superior to the parent form.

G. TINCTORIA ELATIOR (_syn G. elatior_) grows to 12 feet in height, is
of free, spreading growth, and a very handsome plant. The flowers, which
are individually small and yellow, are so thickly produced that the
shrub, in late summer, has the appearance of a sheet of gold.

G. TRIANGULARIS (_syn G. triquetra_).--South Europe, 1815. This is a
decidedly good garden plant, and of neat, trailing habit. The stems are
three sided, and the flowers golden yellow and plentifully produced. A
native of South Europe, and perfectly hardy in almost any position.

The above include most of the hardy Genistas, though G. capitata and G.
daurica, both very ornamental kinds, might be added to the list. They
are all very hardy, free-flowering shrubs, of simple culture, and
succeeding well in any light and rather dry soil.

GLEDITSCHIA.

GLEDITSCHIA TRIACANTHOS.--Honey Locust. United States, 1700. As an
ornamental hardy tree this is well worthy the attention of planters, the
pinnate and bipinnate foliage being particularly elegant, while the
flowers, though individually small, are borne in such quantities of
fascicled racemes as to attract notice. The stem and branches are armed
with formidable prickles, but there is a form in which the prickles are
absent. A native of North America, and readily cultivated in any soil of
even fair quality. For town planting it is a valuable tree. There is a
good weeping variety named G. triacanthos pendula.

G. SINENSIS (_syn G. horrida_).--China, 1774. This nearly resembles the
latter, and is occasionally to be met with in cultivation in this
country.

GORDONIA.

GORDONIA LASIANTHUS.--Loblolly Bay. North America, 1739. A shrub of
great beauty, but one that, unfortunately, is rarely to be seen outside
the walls of a botanic garden. It is of Camellia
