as fully expanded, dyed various colours, and used for decorative purposes. 
They will grow in almost any soil, and are easily propagated by dividing 
the roots; or they may be grown from seed. 
Popo.epis (Greek, pous, a foot, and lepis, a scale; from the bracts 
at the top of the footstalk). Another group of Everlastings, so far as 
the involucres are concerned. The ray-florets are strap-shaped in a 
single series. The flowering plant somewhat resembles Acroclinium 
roseum. The two best-known species are: Podolepis wristata, with the 
bracts ending in a bristle-point, and golden disks with small pink rays; 
July; annual. P. gracilis is a more delicate perennial species with 
purple, lilac, or white heads; August; should be grown as an annual. 
Both species have similar lance-shaped, stem-clasping leaves, and come 
from Australia. Seeds may be sown in a sunny border in May; the 
seedlings being thinned out, not transplanted; or in April if on gentle 
heat. In the latter case a few seeds should be sown in each pot, and the 
plants turned out in June with a ball of earth round each root. A foot 
should be allowed between each two plants. 
INULA (the classical name used by Horace). Rigid herbs with erect 
alternate leaves ;. bell-shaped involucre, the bracts in several series; 
florets yellow (rays occasionally white), Principal species: Inula 
glandulosa, introduced from the Caucasus (1804). About 2 feet high, 
- with flower-heads 5 inches across, solitary; July and August. J. ensi- 
_ folia is a smaller plant of neat bushy habit, with a profusion of golden 
heads 14 inch across; J uly to September. Introduced from Austria (1793). 
Both these plants are hardy perennials, easily grown in any garden soil 
from seed sown in March, or propagated by divisions. 
BUPHTHALMUM (Greek, bous, an ox, and ophthalmos, the eye). 
Oxeye. Flower-heads large and showy, yellow, rayed. Principal 
Species: Buphthalmum salicifolium, with narrow leaves and large

speciosa (B. cordifolium of gardens) is 4 feet high, with heart-shaped 
leaves and bright yellow flower-heads, 3 inches across, with long rays; 
June to August. Introduced from Hungary (1739). Both hardy 
perennials of easy culture, propagated in spring or autumn by 
divisions. 
SANVITALIA (named in honour of a Parma family, the Sanvitali). 
Sanvitalia procumbens is a commonly cultivated half-hardy annual of 
trailing habit, with oval leaves and showy flower-heads with yellow rays
