tubs, and transferred to the conservatory, 

 if there is sufficient room, and its fine 

 leaves will retain their green freshness, 

 and new ones even will be developed, 

 thus rendering the plant a useful winter 

 ornament. In cold bleak parts of the 

 country it requires a slight protection in 

 severe winters. Increased by seed and 

 division. 



A. spinosissimus. — A distinct and 

 handsome species, about 3^ ft. high, 

 native of S. Europe. Leaves tufted, 

 leathery, pinnately divided, blistered and 

 densely armed with sharp, white spines. 

 Flowers in summer and autumn, rosy 

 flesh-colour, in spikes 12-18 in. high, 

 furnished with acute recurved and very 

 spiny bracts. 



Culture £c. as above. Increased by 

 division and seed. 



A. spinosus. — A beautiful species 2-4 

 ft. high, native of Central and S. Europe. 

 Leaves pinnately cut into regular 

 divisions, each ending in a short, stifftsh 

 spine. Flowers in summer, purplish, in 

 the axils of spiny bracts on tall spikes. 



Culture dc. as above. This is perhaps 

 the hardiest species of all and also the 

 most free-flowering. It may be increased 

 by division, seeds, or root cuttings. 



DIANTHERA (Watbr Willow).— A 

 genus containing 80 species of erect, 

 ascending, diffuse or trailing herbs with 

 entire or rarely toothed leaves. Calyx 

 deeply divided in 5 or 4 narrow awl- 

 shaped segments. Corolla tube slender, 

 straight or incurved; limb 2-lipped. 

 Stamens 2. Staminodes none. 



D. americana (Justicia pedunculosa). 

 A pretty N. American water perennial 1-3 

 ft. high with narrow lance-shaped almost 

 stalkless leaves 3-4 in. long. Flowers in 

 summer, pale violet or whitish, less than 

 ^ in. long, several in a head. 



Culture OMd Propagation. — This plant 

 is suitable for growing at the edges of 

 streams, ponds &c. It may be increased 

 by cuttings of the green shoots vmder a 

 handlight, or by seeds sown in spring in 

 gentle heat. 



LXXXVII. SELAGINEiE— Globe Daisy Order 



A small order of shrubs or undershrubs, often Heath-like in appearance, or 

 perennial tufted herbs or rarely small annuals. Leaves alternate, or the lower 

 ones rarely opposite or radical, entire or toothed, often narrow or leathery. 

 Mowers hermaphrodite, irregular, white, blue, or rarely yellow, in dense 

 rounded or oblong terminal or very rarely axillary spikes. Calyx inferior, 6- 

 cleft or parted, or owing to some of the segments being united or absent, 

 variously 3-parted, 2-parted, or spathe-like. Corolla gamopetalous shortly 

 and slenderly tubular at the base, sometimes widened at the throat; limb 

 normally d-S-lobed, spreading. Stamens didynamous, or rarely 2. Ovary 

 superior, usually 2-celled. Fruit small, enclosed by the calyx. 



garden. They like a rich, free, sandy 

 loam, and warm sheltered situations, and 

 are increased by seed sown in spring, or 



GLOBULARIA (Globe Daisy).— A 

 genus containing about a dozen species 

 of undershrubs or herbaceous perennials. 

 Leaves radical or alternate, leathery 

 obovate oblong or lance-shaped, entire or 

 with a few sharp teeth. Flowers blue, 

 rather small, coUeeted in a globose ter- 

 minal head and surrounded by a many- 

 leaved involucre, or rarely dense clustered 

 and axillary. Calyx more or less beU- 

 shaped, 5-lobed, or slightly 2-lipped. 

 CoroUa oblique 8-5-lobed, 2-lipped. Sta- 

 mens 4, didynamous. Ovary 1 -celled. 

 Fruit small, 1-seeded. 



Culture amA Propagation. — Globu- 

 larias are suitable for the border or rook 



by division in early autumn. To make a 

 show it is necessary to grow several plants 

 together. 



G. Alypum. — A somewhat tender S. 

 European species about 2 ft. high, having 

 lance-shaped entire or 3-toothed leaves. 

 Flowers in August and September, pale 

 blue, in rounded terminal heads. 



Culture So. as above. Often grown 

 as a greenhouse plant, but in the southern 

 parts of the country grows very well and 

 requires shelter only in bad winters.
