Gymnostachys continued. 



compost of peat and loam. Propagated by suckers and 



by divisions. 



G. anceps (two-edged). JL white, small, sessile, but not closely 

 packed ; perianth segments or scales obovate, truncate, not 

 exceeding the ovary ; scapes nearly as tall as the leaves, much 

 flattened, with acute, smooth, or serrulate-scabrous edges.

 to 3ft. long. Roots tuberous, fusiform. Australia, 1820. 



GYMNOSTACHYUM (from gymnos, naked, and 

 stocky s, a spike; probably on account of the absence of 

 bracteoles). SYN. Cryptophragmia. OBD. Acanthaceoe. A 

 genus of about fourteen species of ornamental stove ever- 

 green erect herbs, natives of the East Indies and the 

 Malayan Archipelago. Flowers tubular, in erect spike- 

 like racemes. Leaves cauline or sub-radical, entire or 

 obscurely sinuate. The species here described are those 

 usually seen in cultivation. For culture, see Eran- 

 thenmm. 



G. ceylanicnm (CeylonX* JL small, pretty, in pseudo-verticils ; 

 corolla white, tipped with green and yellow. Winter. Z. oppo- 

 site, spreading horizontally, oval or obovate, obtuse, obscurely 

 serrated, having milk-white stains upon a dark green ground. 

 Stem very short, downy. Ceylon. (B. M. 4706.) 

 G. vennsta (charming).* fl. purple, remotely fasciculated, sub- 

 sessile, disposed in slender elongated racemes ; panicles large, 

 terminal. September. I. ovate-acuminate, crenate. h. 5in.

GYMNOTHRIX. Now referred to Fennisetnm 



(which see). 



GYNANDROPSIS (from gyne, a female, andros, a 

 male, and opsis, appearance; stamens appear as if in- 

 serted on the top of the ovary). OBD. Capparideae. A 

 genus containing about ten species of half-hardy or green- 

 house annual herbs, natives of tropical regions of both 

 hemispheres. Flowers white or purple, often showy ; 

 racemes leafy. Leaves three to seven-foliolate. For cul- 

 ture, see Cleome. 



G. coccinea (scarlet). /. scarlet, in a many-flowered corymbose 

 terminal raceme. Summer. 1. long-stalked, palmipartite. h. 

 6ft. to 9ft Columbia, 1878. A beautiful cool-house plant. 

 G. pentaphylla (five-leaved), fl. white ; petals obovate, four 

 times the length of the calyx ; stamens inserted upon the middle 

 of the gynophore. June and July. L quinate ; segments ob- 

 ovate-lanceolate or elliptical-lanceolate. Stem unarmed, h. 2ft. 

 East and West Indies, 1640. Greenhouse. (B. M. 1681, under 

 name of Cleome pentaphylla.) 



GYNERIUM (from gyne, female, and erion, wool; 

 in reference to the stigmas being woolly). Pampas Grass. 

 OBD. GraminecB. A genus of three species of very orna- 

 mental hardy, or nearly hardy, herbaceous grasses, natives 

 of tropical and sub-tropical America. They have two- 

 flowered spikelets and dioecious flowers. 6. argenteum 

 thrives best in a light sandy soil, well enriched with 

 stable manure. The best positions for it are well- 

 prepared shrubbery borders, or sheltered places in the 

 flower garden or pleasure ground, where it will be pro- 

 tected from high winds. It requires plenty of water 

 when making growth. Propagated by seeds, sown under 

 glass, the young plants being grown on in pots until suffi- 

 ciently large to plant outside. If it is desired to utilise 

 the plumes for indoor decoration, they should be cut 

 from the plants during the latter part of summer. 

 G. argenteum (silvery).* fl. disposed in a very large, dense, ter- 

 minal, silky panicle, which, including the stalk, attains a height 

 of from 6ft. to 10ft. Autumn. I. linear, glaucous-green, about 

 6ft. long, in large dense tufts, 4ft. to 6ft. high, and as much 

 across ; edges very rough. Temperate South America, 1848. 

 See Fig. 164. Varieties have been raised with purplish or 

 yellowish-tinted panicles. 



GYNOPHORE. The stalk of the ovary, within the 

 origin of the calyx. 



GYNURA (from gyne, female, and oura, a tail ; in 

 reference to the rough, elongated stigma). OBD. Com- 

 posite. A genus comprising about twenty species of 

 stove perennial herbs, inhabiting the tropics of the 

 Eastern hemisphere. Flower-heads corymbose or soli- 

 tary, at the tops of the branches. Leaves alternate, en- 

 tire, dentate or pinnate, lobed or dissected. Gynuras

thrive in a compost of sandy loam and peat, and are 

 propagated by cuttings. The three species described 

 below are those usually seen in cultivation. 

 G. anrantiaca (orange-coloured).* fl.-heads brilliant orange- 

 colour, aboutJiin. across ; florets all tubular. February. I. (and 

 stem) furnished over their entire surface with small hairs of a 

 beautiful violet colour ; young leaves surrounding the flower- 

 heads especially hairy. A. 2ft. to 3ft. Java, 1880. This may be 

 planted in warm places out of doors during the summer. (I. H. 



G. bicolor (two-coloured), fl.-heads solitary, terminal; invo- 

 lucres cylindrical ; florets rich orange, slightly spreading, uniform, 

 tubular. 1. on the under side purple, sub-membranaceous, broad- 

 lanceolate or ovate-lanceolate, slightly downy, penninerved, petio- 

 late; petiole short. Stem herbaceous, erect. h. 2ft. to 3ft. 

 Moluccas, 1799. (B. M. 5123.) 



G. ovalis (oval-leaved). JL -heads yellow. May to September. 

 1. thickish, villous ; lower ones oval, repand-toothed, stalked ; 

 upper sub-lyrate, amplexicaul. h. 3ft. East Indies. (B. R. 101, 

 under name of Cacalia ocalis.)

GYPSOPHILA (from gypsos, lime, and philein, or 

 love ; in reference to the species preferring a limestone to 

 a chalky soil). OBD. Caryophyllece. A genus containing 

 about fifty species of hardy annual or perennial herbs, 

 inhabiting various parts of Europe and Asia. Flowers 

 white or pink, small, usually disposed in diffuse panicles. 

 Leaves flat or rarely acerose. Some of the species form 

 excellent subjects for growing as border plants or on 

 rockeries. They thrive in a dryish soil, especially if 

 intermixed with calcareous matter or old lime or brick 

 rubbish. Propagated by seeds, by cuttings, or by 

 division. The species described below are perennials. 

 G. cerastioides (Cerastium-like).* fl. white, red-veined, 

 corymbose ; petals emarginate. May. I. pilose on both sur- 

 faces ; margins ciliated ; radical ones spathulate, on long foot- 

 stalks, mucronulate ; cauKne ones obovate. Stems erect, four- 

 sided, h. Sift. Himalaya. (B. M. 6699.) 



G. fastigiata (fastigiate). fl. pale red, corymbosely fastigiate ; 

 petals very rarely emarginated. July. I. linear, rather fleshy, 

 glabrous, flat. h. 1ft. Europe, 1801. (F. d. S. 135.) 

 G. glanca (glaucous), fl. white, panicled ; panicle divaricating.
