Olearia (J. G. Olearius, who published a flora of Halle, 1668). Compositae. Tree-aster. Shrubs and trees of Australia and New Zealand, allied to Aster, somewhat planted abroad, but apparently not tested in this country. The tree-asters are of more than 100 species, evergreen, with white, blue or purple rays, many of which are worthy of cult.: Lvs. alternate, or sometimes opposite or fascicled, mostly tomentose beneath: heads various in size, solitary or clustered, sometimes rayless, the involucre with several rows of bracts that have scarious or dry margins; ray-florets female, in a single row; disk-florets perfect: achene terete or somewhat compressed, bearing one or more rows of pappus bristles. Some of the New Zealand species have large usually solitary fl.-heads and stiff lanceolate toothed Lvs., which should be tested in Amer.; Cockayne writes that they require a moist equable climate with low summer temperature, and are not suited to ordinary garden conditions. Speaking of the New Zealand olearias in general, of which there are more than 40 species, Cockayne says that all are well worthy of cult.: some are alpine and subalpine; some are both trees and shrubs, others shrubs alone.
