sunny or half shady positions. The best kinds are : E. 
aurantiacus (Orange Daisy), yellow, 6in., suitable for rockery 
or margins of borders; E. speciosus superba, lilac-purple, 
orange centre, 3ft., a good border plant and flowers useful for 
cutting; C. Coulteri, white with golden centre, i8in., borders; 
E. glabellus, lilac, i8in., borders ; E. macranthus, violet-purple, 
i8in., borders ; E. philadelphicus, rosy-pink, 1 f t. , margins of 
borders; E. Roylei, blue, 6in., rockeries; E. Villarsii, soft 
lilac, i ft., borders. Mostly N. American species. Plant in 
autumn or spring. The tall kinds require to be supported by 
stakes, otherwise their shoots will sprawl about. Increased by 
division of the roots in autumn or spring; also by seeds sown 
in sandy soil in cold frames in autumn or spring. 
Erinus. — E. alpinus is a dwarf perennial of tufted growth, 
which bears violet-purple flowers in spring and summer, and 
belongs to the Foxglove order (Scrophulariaceae). The white 
variety (albus) and the red one (carmineus) are both very pretty. 
A native of the Alps. The species and its varieties should be 
grown on old walls or on sunny rockeries. Sow seeds in the 
chinks of the walls or among the rocks on the rockery in April, 
then nice tufted plants will be obtained in due course. Once 
established the plants will freely reproduce themselves from 
seed. May also be increased by division of the roots in 
autumn. 
Eriogonum. — Hardy perennial herbs, belonging to the 
Buckwheat family (Polygonaceae). The only species worthy 
of culture is E. umbellatum. This is of tufted growth, and 
bears pretty yellow flowers in dense umbels on stems 6in. high. 
The variety Sileri is said to be an improved form of this 
species. A native of California. Both should be grown in 
sandy loam on a sunny rockery. Plant in spring. Increased 
by seeds sown in sandy soil in a cold frame in spring ; also 
by division of the roots at the same time. 
Eritrichium (Fairy Forget-me-not). — E. nanum, the 
only species we shall describe in this work, is a dwarf, tufted 
alpine plant, growing 2 to 3m. high, and bearing azure or sky- 
blue flowers in summer. It resembles somewhat a dwarf Myo 
sotis, and belongs to the Forget-me-not order (Boraginacese). 
It is not a very easy plant to grow on account of its cottony 
foliage being susceptible to injury from damp in winter. 
Plant in fibrous loam and peat, mixed with small pieces of 
sandstone, and put a few pieces of the latter round the plant 
to keep its foliage off the soil. March is a good time to plant. 
Increased by seeds sown in sandy peat in a cold frame in 
spring, or division in March.
