(Eurybia, Cass.) 
Shrubs or trees. Leaves alternate or fascicled, very rigid, coriaceous, with 
white or buff tomentum below. — Heads large or small, rayed, corymbose or 
solitary, peduncled or sessile. Involucre of imbricate, rigid scales. Recep- 
tacle convex, alveolate or almost even. Florets 20-100 (rarely 1-4); outer 
female, in one row, ligulate, white, the rest tubular, hermaphrodite ; anthers 
with very short tails. Pappus of one or more rows of long, rigid, usually un- 
equal, scabrid hairs, acute or thickened at the points. Achenes ribbed, terete, 
not flattened. 
A very large New Zealand and Australian genus, which will possibly have to be united 
with some others of the Old or New World ; most were included, by De Caudolle, under 
Eurybia, Cass., a genus established on the siugle pappus, but which cannot be separated 
from Olearia. The small N. Zealand section, having opposite pairs or fascicles of leaves, might 
(on account of its habit) be separated generically, were it not for intermediate Australian 
forms. The terete (not compressed) achene and short tails to the anther-cells, distinguish the 
genus from the Northern shrubby Asters ; and the branched, shrubby or arboreous habit 
alone from Celmisia and Fleurophyllum. The three first species, or two of them, may prove 
varieties of one, as may the fourth and fifth of another.
