21. O. moschata, Hook. f. Handb. N.Z. Fl. 127.—A much-branched shrub 4–12 ft. high, with a strong musky fragrance; branches stout, spreading; branchlets, inflorescence, and leaves beneath clothed with soft white densely appressed tomentum. Leaves alternate, close-set, ⅓–¾ in. long, obovate-oblong, obtuse, narrowed into a very short petiole, quite entire, coriaceous, glabrous or slightly pubescent above, veins altogether concealed below; margins flat. Corymbs small, lax or compact, on long axillary peduncles much exceeding the leaves; pedicels slender, tomentose. Heads few, ¼ in. long, campanulate or broadly turbinate; scales of the involucre in few series; the outer short, ovate, obtuse, tomentose; the inner linear-oblong, obtuse, pubescent or nearly glabrous.
