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 
y seen in cultivation. For culture, see Eran-

GYMNOTHRIX. Now referred to Pennisetum

GYNANDREOPSIS (from gyne, a female, andros, a 
male, and opsis, appearance; stamens appear as if in- 
serted on the top of the ovary). ORD. Capparidee. 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-foliate. For cul- 
ture, see Cleome. 
G. coccinea (scarlet). 7. scarlet, in a many-flowered corymbose 
terminal raceme. Summer. J. long-stalked, partite. h. 
6ft. to 9ft. Columbia, 1878. A beautiful cool-house plant. 
G. pentaphylla (five-leaved)., jl. white; petals obovate, four

East and West Indies, 1640. Greenhouse. (B. M. 1681, under 
name of Cleome pentaphylla.) 
GYNERIUM (from gyne, female, and erion, wool;

ORD. Graminee. 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 dicecious flowers. G. argentewm 
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).* /l. disposed in a very large, dense, ter- 
minal, silky panicle, La including the stalk, pri ok a height 
of from 6ft. to 10ft. Autumn. Z. 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). ORD. 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

propagated by cuttings. The three species described 
below are those usually seen in cultivation. 
G. aurantiaca (orange-coloured).* — brilliant orange- 
colour, about}}in. across ; florets all tubular. February. Z. (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 
— in warm places out of doors during the summer. (I. H. 
56.) 
G. bicolor (two-coloured), l.-heads solitary, terminal; invo- 
lucres cylindrical ; florets rich orange, slightly spreading, uniform, 
tubular. l. on the under side purple, sub-membranaceous, broad-

GYPSOPHILA (from gypsos, lime, and philein, or 
love; in reference to the species preferring a limestone to 
a chalky soil). ORD. Caryophyllee. 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),* jl. white, red-veined,
