the stems and branohes. Flowers in 

 summer, small, pale yellow, whitish or 

 purple in small rounded heads at the tops 

 of the branches. 



Culture Sc. as above. Warm sunny 

 sheltered spots in the rook garden in sandy 

 soil. Increased by seeds, cuttings, and 

 division. 



T. pyrenaicum. — A downy Pyrenean 

 perennial 3-6 in. high, with roundish 

 notched leaves thickly covered with soft 

 down. Flowers in summer, purple and 

 white, in dense terminal clusters. 



Culture dc. as above. The rock garden 

 or border. Increased by seeds, cuttings, 

 and division. 



AJUGA (Bugle). — A genus con- 

 taining about 30 species of annual or 

 perennial herbs, often decumbent or 

 stolon- or runner - bearing, and having 

 coarsely toothed or incised, rarely entire, 

 leaves, the upper ones more or less bract- 

 like. Calyx ovoid or roundish bell-shaped, 

 8-10-ribbed, 5-toothed or cleft. Corolla 

 2-lipped, with a tube slightly expanded 

 at the throat. Stamens 4, didynamous. 

 Ovary shortly or almost to the middle 

 4-lobed. Nutlets obovoid, reticulate, 

 wrinkled. 



Culture and Propagation. — The 

 Ajugas flourish in ordinary garden soil 

 and prefer half-shaded situations although 

 they also succeed in the sunshine. They 

 are easily increased at the end of summer 

 or in spring by dividing the tufts, which 

 may be repla,nted 8-9 in. apart. Seeds 

 may also be sown in the open border in 

 April or May, or as soon as ripe in 

 autumn. Although not in the best sense 



ornamental, Ajugas are useful in the 

 rock garden or as edgings to borders, 

 margins of shrubberies &c. 



A. genevensis {A. alpina; A. rugosa). 

 A hairy runnerless European perennial 

 6-12 in. high, with oblong coarsely 

 toothed green and hairy leaves narrowed 

 at the base. Flowers in early summer, 

 varying from blue to rose and white, in 

 distant and spioate whorls. A very 

 variable plant ; increased by division. A. 

 pyramidalis seems to be a form of it 

 having the floral leaves crowded into 

 4-angled or pyramidal spikes. 



Culture dc. as above. 



A. orientalis. — A native of Eastern 

 Europe 12-18 in. high, with woolly hairy 

 stems. Leaves large, stalked, ovate, 

 coarsely and sinuately toothed, narrowed 

 at the base, floral ones stalkless broadly 

 ovate deeply lobed or toothed. Flowers 

 in early summer, blue, 6 or more in a 

 whorl. 



Culture <tc. as above. This species 

 likes dry sunny spots in the rockery. 

 Increased by division and seed. 



A. reptans. — A smooth creeping 

 British herb 4-8 in. high, with runners 

 and entire or sinuate ovate leaves, the 

 lower ones stalked, the upper nearly 

 sessile. Flowers in summer, ^f in. 

 long, blue, rarely white or rosy, in spikes 

 3-8 in. long. 



Culture Sc. as above. There are varie-

 more handsome than the type and useful 

 as edging plantg. They are quickly in- 

 creased by division in ordinary soil, or seed.
