spring, afterwards transferring the seed- 

 lings to the open border when large enough. 

 They are excellent plants for the rock 

 garden, or in front of the herbaceous 

 border, but to obtain the finest effects 

 they should be grown in bold masses. 



E. alpinus. — A pretty native hairy 

 perennial, 9~-]2 in. high, suitable for 

 rockeries. Leaves oblong lance- shaped 

 below, linear oblong above. Flowers in 

 July and August, } in. across, purple, with 

 a yellow centre. The variety grand/l- 

 floriis is superior to the type. 



Culture d-c. as above. 



E. aurantiacus. — A native of Turkestan 

 it-12 in. high. Leaves oblong entire, 

 upper ones lance-shaped, sessile. Flowers 

 ill early and late summer, about "2 in. 

 across, bright orange, solitary, on a stout 

 erect peduncle. 



Culture dc. as above. This species is 

 remarkable for the bright orange-yellow 

 of its flowers, so utterly distinct from 

 other species of Erigeron. It may be 

 increased by division, but not quite so 

 rapidly as some others, and it is therefore • 

 advisable where a large stock is required to 

 obtain plants from seeds also. 



E. caucasicus. — A Caucasian perennial 

 9-12 in. high, with lower leaves spoon- 

 shaped, upper ones strap-shaped, stem- 

 clasping. Flowers in summer, about 

 1 in. across, rosy-pink, or purple, in loose

 habit. Leaves oblong ovate or somewhat 

 spoon-shaped, ciliated, glaucous, clammy, 

 lower ones with winged stalks, upper 

 ones sessile. Flowers in summer and 

 autumn, lilac-purple. 



Culture dc. as above. This is an 

 evergreen species and retains its foliage 

 during the winter months. It is easily 

 increased by division. 



E. grandiflorus. — A Bocky Mountain 

 perennial 4-8 in. high. Lower leaves 

 obovate spoon-shaped, upper ones oblong 



to lance-shaped. Flowers late in sum- 

 mer, purple or whitish, rather large. 



Culture dc. as above. This species 

 makes fine evergreen masses of foliage, 

 and may be used as a carpeting for taller 

 plants. Easily increased by division. 



E. mucronatus {Vittadinia triloba; 

 V. australis). — A much-branched, spread- 

 ing perennial 6-12 in. high, native of 

 Australia and New Zealand. Leaves 

 wedge-shaped or narrowly spoon-shaped, 

 3-5-lobed at the apex. Flowers during 

 summer, ray florets white tipped with

E. multiradiatus. — A pretty Himalayan 

 plant 6-24 in. high, with oblong, toothed 

 leaves tapering into a long stalk. Flowers 

 in summer, about 2 in. across, purple with

 rootstocks, and forming dense masses of 

 foliage close to the groimd. The soft 

 mauve-tinted flowers with a yellow centre 

 are about 3 in. across, appear in May and 

 June, and are very effective when seen in 

 bold masses. 



Culture dc. as above. 



E. speciosus {Stenactis speciosa). — A 

 showy N. American perermial about 2 ft. 

 high. Lower leaves spoon-shaped, long- 

 stalked ; upper ones lance-shaped acute, 

 sessile, 2-4 in. long. Flowers in summer, 

 violet-purple, 2 in. or more across, in 

 corymloose heads ; centre yellow. The 

 variety superhus is a larger and finer 

 flower, approaching in appearance smaller 

 forms of the typical Ca.ZWsiep7!2(s Jiortensis 

 described at p. 499. 



Culture dc. as above. This is the 

 best known of all the Erigerons. It 

 makes dense tufts close to the ground,
