GILIBERTIA (named after J. E. Giliberfc, 1741- 

 1814, a French botanist and physician). ORD. Araliacecc. 

 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. 



G. brasiliensis (Brazilian), fl,. greenish. February and March. 

 I. leathery, dark green. A. 4ft. to 6ft. 



CrlLLENIA (named after Arnoldus Gillenius, a 

 botanist of the seventeenth century). ORD. Rosacece. 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, 

 trifoliolato ; 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. 

 G. Stipulacea (stipulaceous). fl. white. June. I. lanceolate, 

 deeply incised, h. 1ft. to 2ft. "

 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. 



G. graminea (grass-like), fl. green, inconspicuous, drooping ; 

 umbels divaricate, few-flowerod ; spathe two-valved, green, erect, 

 persistent; scapes weak, terete, decumbent. September. I.

GILLIFLOWER. A name corrupted from the French 

 Giroflee; 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, Mattliiola and Clieiranthus " (Britten and 

 Holland, " Dictionary of English Plant Names "). 



GINGER. The Ginger of commerce is the dried 

 rhizomes of Zingiber ofiiciiiale (which see). It is 

 imported into this country in its dried and bleached

 used both as a condiment and as a preserve.

 STNS. Salisburia, Pterophyllus. ORD. Coniferce. A mono- 

 typic genus, the species being a fine deciduous tree. It 

 thrives thoroughly well in almost any garden soil in the 

 South of England, but in the North requires the shelter

 Propagated by imported seeds. 

 G. biloba (two-lobed).* fl. dioecious; male catkins slender, stalked; 



females in pairs, or solitary, on long footstalks. Spring, fr.
