included under Ornithogalum. Flowers greenish-yellow, on 
a scape, in a terminal bracteated umbel. Leaves radical, 
linear. The species closely resemble each other; but few 
of them, however, are seen in gardens. For culture, see 
Ornithogalum. 
G. lutea (yellow).* Yellow Star of Bethlehem. fl. three or four 
in a flat raceme, almost contracted into an umbel ; the leaf-like 
bracts as long as the pedicels or longer ; perianth segments yellow, 
with a green back, very spreading, narrow-oblong. Spring. l. 
one, or very rarely two, linear, pointed and curved like those of a 
Tulip. Stem slender, rarely 6in. high. Europe and Russian 
Asia, except the extreme North; also occurring in several parts 
of England, and, but rarely, in the Lowlands of Scotland.

G. stenopetala (narrow-petaled). fi. in umbels; perianth pale 
yellow, deeply six-parted. March. ` l., root ones solitary, glau- 
cous, revolute, linear-lanceolate, acute, strongly three-nerved ; 
scape leaves — lanceolate, acute, age keeled, glaucous, 
agen pig and fringed with long hairs. Europe. (Š. B. F. G. 
77, under name of G. glauca.) 
GAGNEBINA (named in honour of P. Gagnebin, a 
botanical writer of the seventeenth century). ORD. Legu- 
minose. An elegant, unarmed, stove evergreen shrub, 
closely allied to Mimosa (which see for cultivation). 
G. tamariscina (Tamarix-like). fl. yellow; spikes crowded at 
the top of the branches, disposed in a kind of racemose corymb. 
l. with about twenty pairs of pinne, each pinna bearing about 
thirty pairs of leaflets. h. 6ft. Mauritius, 1824. 
GAILLARDIA (named in honour of M. Gaillard, a 
French patron of botany). ORD. Composite. A genus 
of very ornamental hardy annual or perennial herbaceous 
plants, natives of North and extra-tropical South Ame- 
rica. Flower-heads yellow or purple, 2in. across, single, 
and supported on naked stalks; ray-florets three to five- 
toothed, often two-coloured ; receptacle furnished with 
filiform bristles between the florets. Leaves sometimes 
pinnatifid, but usually entire or obscurely toothed, lance- 
shaped and rough; the cauline ones sessile. There are 
about eight species, all thriving in a good light friable 
soil, in masses. Propagation may be effected by cuttings, 
in autumn or spring; also by division, in the latter 
season. In cold localities, the perennial species fre- 
quently die in winter: in this case, seeds should be sown 
on a mild hotbed, in February or March. The best

method of propagating the annuals is by cuttings, which 
are readily obtainable, as these form far superior plants 
to those procured from seed. 
G. amblyodon (blunt-toothed).* .-heads terminal, peduncled; 
ray-florets deep blood-red, twelve to fourteen, spreading ; limb 
cuneate-oblong, obtusely three-lobed; disk-florets short. October.

GALACTIA PINNATA. A synonym of Barbieria

GALACTITES (from gala, galaktos, milk; in allu- 
sion to the veins of the leaves being milk-white). ORD. 
Compositæ. A genus of hardy annual or biennial erect 
herbs, nearly allied to Onicus, from which it differs 
chiefly in the outer florets of the flower-head being sterile 
and larger than the others, as in Centaurea. Leaves 
pinnatifid, with spiny - pointed segments, spotted with 
white above, and covered with cotton -down below. 
There are three species, all inhabiting the Mediterranean 
region. They thrive in any common garden soil, and 
may be propagated by seed, sown in the flower border, 
in March or April. The species here described is the 
one best known to cultivation. is

Amaryllidee, A well-known genus, containing three 
species of hardy bulbous plants. It is distinguished from 
Leucoium principally in having the three inner segments 
of the perianth shorter than the outer. Snowdrops are 
well-known and general favourites, on account of the 
modest beauty displayed by their flowers at the early 
season in which they appear; hence, no word of recom- 
mendation is needed to insure their cultivation, which 
is of the simplest description, as the roots thrive in 
almost any soil or position outside. When once planted, 
it is best to let them take care of themselves, as liftin 
has a tendency to dry the bulbs, which is not desirable 
if it can be avoided. Snowdrops are cheap and attractive —
