seventy species) of half-hardy, annual, biennial or 
perennial herbs, abounding in tropical America and 
Australia, one species being widely dispersed through 
Asia and tropical Africa. Flower-heads generally sessile 
and solitary at the tips of the branches. Leaves oppo- 
site, sessile or shortly-stalked, entire. The common 
globe-flowered species is one of the prettiest hardy 
plants grown. It is admirably adapted for the summer 
decoration of greenhouses and conservatories, forming a 
neat, erect-branched growth of about 2ft., and apro- 
fusion of richly- coloured flower-heads. In order to 
retain the beauty of these for a considerable period, 
they should be cut previous to full maturity. For 
eulture, see Celosia.

(B, M. 2815.) Of the many varieties, nana is perhaps the 
rettiest, with flowers of a fine dark red; it rarely exceeds Sin. 
in height, and is usually 7in. to 8in. in diameter. Other 
varieties are: alba, aurea superba, carnea, Isabellina, pur-

A singular genus, comprising more than a score species of 
ornamental, evergreen, stove epiphytal orchids, natives of 
tropical America. Flowers drooping, in racemes, some- 
times 2ft. long; lateral sepals free and spreading; upper 
one remote and connate with the column; petals small, 
adnate to the middle of the column; lip clawed, continuous 
with the base of the column. Leaves broadly lanceo- 
late, plaited, 1ft. or more long. Pseudo-bulbs oblong, 
two-leaved. Gongoras should be grown in baskets of 
peat and moss, and with the temperature of a cool end 
of the Cattleya house. A liberal supply of water, both 
to leaves and roots, may be applied during summer. 
During winter, little will be required, but the pseudo- 
bulbs must not be allowed to shrivel. This genus, 
although somewhat neglected of late, possesses several 
free-flowering and handsome species, of which the follow- 
ing are a selection : 
G. armeniaca (Apricot-coloured). fl. rich yellow, slightly spotted 
with red; raceme rather lax, twelve to twenty-flowered, pendu- 
lous, 1ft. or more long. Summer. l twin, broad, light green, pro- 
duced on the top of the oval pseudo-bulbs. Nicaragua, 1850.

GONOLOBUS (from gonia, an angle, and lobos, a 
pod; in reference to one of the original species having 
costate-angled follicles). ORD. Asclepiadew. A genus 
containing about seventy species of stove, greenhouse OF 
hardy, twining or prostrate, shrubs or sub-shrubs, natives 
of tropical and North America, Flowers dull or dark- 
coloured, in racemes or corymbs ; peduncles interpetiolar ; 
corolla rotate or reflexed, spreading; limb five-parted. 
Leaves opposite, very often cordate. The greenhouse 
and stove species thrive, with ordinary treatment, in a. 
compost of loam and peat. Cuttings will root readily 
in sand, under a glass. The hardy sorts require a light 
sandy soil, and a warm dryish situation; and may be 
increased by divisions or by seeds.
