GILIBERTIA (named after J. E. Gilibert, 1741- 
1814, a French botanist and physician). ORD. Araliacee. 
A genus comprising two or three species of ornamental 
evergreen shrubs, natives of tropical America. Flowers 
in terminal compound umbels. Leaves simple, entire. 
The species described below is, perhaps, the only one 
yet in cultivation. It thrives in a compost of sand, leaf 
mould, and light loam. Increased readily by cuttings, 
inserted in sand, in a gentle heat.

l. leathery, dark green. A. 4ft. to 6ft. 
GILLENIA (named after Arnoldus Gillenius, a 
botanist of the seventeenth century), ORD. Rosacee. A 
genus comprising two species of hardy perennial herbs, 
natives of Northern United States. Flowers axillary 
and terminal, on very long peduncles, Leaves sub-sessile, 
trifoliolate ; leaflets stalked, serrated. Gillenias are of easy 
culture, in a rather moist peaty soil, with partial shade. 
Increased readily by dividing the roots, in spring.

ing three species of bulbous herbs, natives of Chili. 
Flowers greenish, in terminal umbels; scape simple, leaf- 
less. Leaves few, radical, linear. G. graminea, the species 
best known to cultivation, thrives in a loam and peat 
soil, in a warm border; it requires a little protection 
in winter. Propagated by offsets. 
graminea (grass-like). fl. green, inconspicuous, drooping ; 
umbels divaricate, few-flowered ; spathe two-valved, green, erect, 
persistent; scapes weak, terete, decumbent. September. Z

GILLIFLOWER. A name corrupted from the French 
Giroflée; it is also written Gillyflower and Gilloflower. 
“ The name was originally given, in Italy, to plants of the 
Pink tribe, especially the Carnation, but has of late years, 
in England, been transferred to several cruciferous plants. 
That of Chaucer, Spencer, and Shakespeare was, as in 
Italy, Dianthus Caryophyllus ; that of later writers and 
gardeners, Matthiola and Cheiranthus” (Britten and 
Holland, “ Dictionary of English Plant Names ”). 
GINGER. ‘The Ginger of commerce is the dried 
rhizomes of Zingiber officinale (which see). It is 
imported into this country in its dried and bleached
