GLYCYRRHIZA (the old Greek name used by 
Dioscorides, from glykys, sweet, and rhiza, a root; in 
reference to the sweetness of the root). Liquorice. In- 
cluding Liquiritia. Orp. Leguminose. A genus com- 
prising about twelve species of hardy herbaceous peren- 
nials. Flowers blue, violet, white, or yellow, in axillary 
racemes. Leaves pinnate. Root long, perpendicular, 
sweet. These rather coarse-growing plants succeed in 
a deep sandy loam. Propagated by divisions, each of 
which should have one or more buds. The species most 
cultivated is G. glabra, from which is obtained the true 
liquorice. 
G. echinata (prickly). fl. purple, in racemes not half so long as 
the leaves. June and July. l., leaflets oval-lanceolate, mucro- 
nate, glabrous ; stipules oblong-lanceolate. R. 3ft. Europe, 1596. 
Whole plant glutinous to the touch. (B. M. 2154.) 
G. glabra (glabrous).* M. pale blue, distant; spikes or racemes 
ger mpi shorter than the leaves: Summer and autumn: 
, leaflets ovate, rather retuse, and somewhat clammy beneath, 
as well as the branches, Stem only terete at the apex. h. 3ft. to 
Ht. Europe, &e., 1562, BOLLS of 
G. lepidota (scaly). fl. whitish; spikes pedunculate, shorter 
than the leaves, dense. July and August. Pods beset with 
hooked prickles. .,J., leaflets.15in. to 19in. long, oblong-lanceo- 
late, acute, squamulose, under surface cove with glandular 
dots> . Root creeping. 2ft. to 3ft. North America, 1817.

allusion to ‘the markings of the fruit). ORD. Tiliacee. 
A genus containing two, species of stove shrubs, natives 
of tropical Africa. Flowers yellow; cymes few-flowered, 
axillary, lateral or terminal. Leaves denticulate, three- 
ribbed.. Eor culture, see Apeiba, = = 
G. grewioides (Grewia-like). -bright yellow, 1}in. in diameter ; 
cymes three to ‘four-flowered, pibescent, with stellate hairs.

or ovate, rounded or slightly unequally cordate at the base, 
acuminate, acutely and irregularly toothed. Benguela, 1866, 
(B. M. 5610, under name of Glyphæa Monteiroi.) 
GLYPHOSPERMA (from glyphe, carving, and 
sperma, seed; in allusion to the markings of the seed). 
ORD. Liliacee. A singular hardy plant, nearly allied to 
the European Anthericum. It has fascicled, fleshy, fibrous 
roots, and slender, soft, bright green, grass-like leaves. It 
thrives in any dry, sandy soil, but should be protected, 
during, winter, from-.excessive moisture. 
G. Palmeri (Palmer’s). fl. white, starry, Zin. in diameter, in 
anicled racemes. 7. linear, channelled, lft. to 14ft. long.

GLYPTOSTROBUS. See Taxodium. 
GMELINA (named in honour of S. Gottlieb Gmelin, 
a celebrated German naturalist and traveller, 1743- 
1774). ORD. Verbenacee. A genus containing eight 
species of stove evergreen trees, natives of East 
India, Eastern Asia as far as China, the Malayan Archi- 
pelago, and tropical Australia. Flowers blue, pale violet, 
or yellow. Leaves opposite, entire. Gmelinas thrive in 
a rich fibry loam. Propagated by cuttings, made of firm 
young shoots, and inserted in sand, in heat. They 
are seldom seen in cultivation in this country; and, in 
all probability, the species described below is the only 
one yet introduced. 
G. Rheedii (Rheed’s |, white ; thyrse many-flowered ; corolla 
downy, bilabinte Pe; August. J. rhomb-cordate, sometimes 
three-lobed, tomentose beneath. h. 20ft. East Indies, 1824, 
Plant arboreous, downy. (B. M. 4395.) 
GNAPHALIUM (from gnaphalon, soft down; woolly 
Covering of the leaves), Cudweed; Everlasting. ORD. 
Gnaphalium— continued. F: 
Composite. A genus comprising about a hundred species 
of hardy, stove, or greenhouse, annuals, biennials, or 
perennials, spread over nearly the whole globe, from the 
tropics to the Arctic Circle. Flower-heads yellow or 
white, small, sessile, often clustered, rarely forming ter- 
minal corymbs; involucral bracts imbricated, scarious 
(whence the English name), and often coloured at the 
tips. Leaves alternate, entire, sessile, decurrent, or 
rarely petiolate. Few of the species (four of which 
are natives of Britain) are worthy of special mention in 
this work.

GNETACEÆ. A small order of shrubs, rarely trees, 
‘natives, for the most part, of tropical regions. Flowers 
moneecious or dicecious, with sheaths or laciniate scales, 
the female with a membranous, tubular, bifid, calyciform 
sheath. : Leaves opposite, reticulated; sometimes scaly. 
The seeds of some of the species arè edible. There are 
three genera—the best-known of which are Ephedra and 
Welwitschia—and about thirty: species. abe aah ae 
GNIDIA (pertaining to Gnidus, a town in Crete; a 
name given by the ancients to the Laurel). ORD. Thyme- 
lacew. A rather latge genus (about fifty species are 
known) of greenhouse evergreen shrubs or under-shrubs ; 
found in the Southern and sv aggre dl tropical parts of 
i white or pale yellow, inconspicuous ; 
pe —— with a regular four-cleft limb. 
— scattered or opposite. Branches slender. The 
lants require a moist atmosphere, and a situation close 
to the glass. In other respects, they should be treated 
like Pimelea (which see).
