LINE.2E. Including Erythroxylece. A small order of 

 herbs, shrubs, or rarely trees, glabrous or rarely hirsute 

 or tomentose. Flowers regular, hermaphrodite, usually 

 terminal, in racemes, panicles, corymbs, heads, fascicles, 

 or spikes ; petals often blue, yellow, or white, rarely pink, 

 fugacious, or, in a few genera, persistent. Leaves alter- 

 nate, or very rarely opposite, simple, entire. Linum 

 usitatissimum yields the flax and linseed of commerce. 

 There are fourteen genera, and 135 species. Illustrative 

 genera are : Erythroxylon, Ixonanthes, Linum. 



LINEAR. Narrow; when the two sides aro nearly

parallel. A Linear-acute leaf is shown in Fig. 444. 

 LINO. See Calluna and Trapanatans. 

 LINGULATE. Tongue-shaped. 



LINNJEA (so named by Gronovius, after the great 

 Linnaeus, at his own request). OBD. Caprifoliacece. A 

 monotypic genus. The species is a very pretty, hardy, 

 trailing, sub-shrubby, creeping evergreen, and forms 

 broad leafy patches. It is a desirable plant for rock 

 gardens, preferably in a rather shaded situation ; and 

 thrives best in a moist peaty soil. Linnaea will also 

 grow luxuriantly in large pots, filled with peat soil. 

 Propagated readily by divisions. 



L. borealls (Northern).* fl. flesh-coloured, twin, pendulous, 

 fragrant ; peduncles axillary ; corolla campanulate, tube cylin- 

 drical ; calyx double. May and June. I. roundish or ovate, 

 firm, slightly hairy. The cold regions of the Northern hemi- 

 sphere (Britain). (Sy. En. B. 644.) 

 LINOSYRJS. See Chrysocoma Linosyris. 

 LINUM (from Linon, the old Greek name used by 

 Theophrastus). Flax. OBD. Lineae. A genus compris- 

 ing about eighty species of glabrous or rarely pubescent, 

 annual, biennial, or perennial herbs or shrubs, natives of 

 all the temperate regions of the globe, but rare in the 

 tropics. Flowers yellow, blue, or rarely rosy, blood- 

 coloured or white, very fugitive, in terminal or axillary
