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. OBD. Leguminosce. A genus com- 

 prising about twelve species of hardy herbaceous peren- 

 nials. Flowers blue, violet, white, or yellow, in axillary 

 racemes. Leaves pinnate. Boot 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 <?. glabra, from which is obtained the true 

 liquorice. 



G. echinata (prickly). 



the leaves. June and July. 'I., leaflets oval-lanceolate, mucro- 

 nate, glabrous ; stipules oblong-lanceolate, ft. 3ft. Europe, 1596. 

 Whole plant glutinous to the touch. (B. M. 2154.) 

 G. glabra (glabrous).* /. pale blue, distant ; spikes or racemes 

 pedunculate, shorter than the leaves. Summer and autumn, 

 t., leaflets ovate, rather retuse, and somewhat clammy beneath, 

 as well as the branches. Stem only terete at the apex. ft. 3ft. to 

 4ft. Europe, &c., 1562. 



G. lepidota (scaly), fl. whitish; spikes pedunculate, shorter 

 than the leaves, dense. July and August. Pods beset with 

 hooked prickles. 1., leaflets 15in. to 19in. long, oblong-lanceo- 

 late, acute, squamulose, under surface covered with glandular 

 dots. Root creeping, ft. 2ft. to 3ft. North America, 1817. 

 (B. M. 2150.) 



GLYPH2EA (from glyphe, carving, carved work ; in 

 allusion to the markings of the fruit). OBD. TiUacece. 

 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. For culture, see Apeiba. 



G. grewloides (Grewia-like). fl. bright yellow, IJin. in diameter ; 

 cymes three to four-flowered, pubescent, with stellate hairs. 

 September. I. glabrous, 4in. to 6in. long, membranous, oblong 

 or ovate, rounded or slightly unequally cordate at the base, 

 acuminate, acutely and irregularly toothed. Benguela, 1866. 

 (B. M. 5610, under name of Glyphasa Monteiroi.) 



GLYFHOSFEBMA (from glyphe, carving, and 

 sperma, seed; in allusion to the markings of the seed). 

 OBD. Liliacece. A singular hardy plant, nearly allied to 

 the European Anthericnm. 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, |in. in diameter, in 



Cicled racemes. 1. linear, channelled, 1ft. to lift. long, 

 them Mexico, 1884. (B. M. 6717.) 



GLYPTOSTROBUS. See Taxodimn. 



GMELINA (named in honour of S. Gottlieb Gmelin, 

 a celebrated German naturalist and traveller, 1743- 

 1774). OBD. Verbenacece. 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, bilabiate. June to August. I. rhomb-cordate, sometimes 



three-lobed, tomentose beneath. A. 20ft. East Indies, 1824. 



Plant arboreous, downy. (B. M. 4395.) 



GNAFHALIUM (from gnaphalon, soft down; woolly 

 covering of the leaves). Cudweed ; Everlasting. OBD. 



Gnaplialium continued. 



Composites. 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.

 Cluster of Flower-heads. 



G. decurrens (decurrent). fl. -heads white, in cymosely disposed 

 glomerules. July and August. I. strongly scented, lanceolate or 

 linear, white beneath, ft. 2ft. to 3ft. North America. Hardy 

 perennial. See Fig. 121. 



G. Leontopodium. See Leontopodium alpinum. 



G. margaritaceum (pearly). Pearl Cudweed. A synonym of 

 Antennaria inargaritacea. 



GNETACE2E. A small order of shrubs, rarely trees, 

 natives, for the most part, of tropical regions. Flowers 

 monoecious or dioecious, 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 are edible. There are 

 three genera the best-known of which are Ephedra and 

 Welwitschia and about thirty species. 



GNIDIA (pertaining to Gnidus, a town in Crete ; a 

 name given by the ancients to the Laurel). OBD. Thyme- 

 lacece. A rather large genus (about fifty species are 

 known) of greenhouse evergreen shrubs or under-shrubs ; 

 found in the Southern and Eastern tropical parts of 

 Africa. Flowers white or pale yellow, inconspicuous ; 

 calyx funnel-shaped, with a regular four-cleft limb. 

 Leaves scattered or opposite. Branches slender. The 

 plants require a moist atmosphere, and a situation close 

 to the glass. In other respects, they should be treated 

 like Pimelea (which see). 



G. denudata (shaven), fl. pale yellow. May to July. I. ovate- 

 oblong, imbricated, hairy, with naked nerves, ft. lift Cape of 

 Good Hope, 1820. (B. R, 757.) 



G. oppositifolia (opposite-leaved), fl. pale yellow, terminal; 

 scales four. May to July. 1. opposite, ovate, tomentose. ft. 1ft. 

 Cape of Good Hope, 1783. (B. M. 1902.) 



G. pinifolia (Pine-leaved).* fl. creamy-white, very fragrant, dis- 

 posed in umbellate heads. March and April. I. scattered, 

 three-cornered, ft. 1ft. Cape of Good Hope, 1768. (B. M. 2016.) 

 G. tomentosa (downy), fl. pale yellow, sessile, collected into a 

 sort of fasciculated head at the extremity of the younger shoots, 

 and surrounded by four closely-placed leaves, which form an 

 involucre ; tube long and slender, swollen at the base, clothed 

 externally with long, white, rather silky hairs ; segments faintly 

 three-nerved. March and April. I. opposite, decussate, more or 

 less spreading, sometimes refiexed, ovate or ovate-lanceolate,
