Art. XXXVII.—Description of a new Roseaceous Plant. By R. Brown. Communicated by Professor F. W. Hutton. [Read before the Philosophical Institute of Canterbury, 3rd May, 1883.] Acæna huttoni. Growing from a stout woody perennial rootstock. Leaves impari-pinnate; radical 5–8 inches long; petioles long, slender, triquetrous, woolly; stipules adnate, small, subulate, decurrent, expanding into a membranous, clasping base; leaflets spirate, or alternate, 11–17, enlarging upwards, the lower sub-rotund, the upper oval or obovate, all sub-plicate, incised, or inciso-dentate, midrib woolly on the under side, veinlets with a few hairs, the upper surface smooth. Peduncles erect, or inclined, sometimes decumbent, angular, woolly, leafy to near the apex; upper leaves becoming sessile and exstipulate, from 9–18 inches high; heads sub-globular, florets sessile with a small scarious bract at the base of each, fimbriated on the margin; bracteola two, sub-rotund, very concave, scarious, fimbriated on the margin, attached near the base of the calyx-tube on spirate angles, and in a young state wholly enclosing the flower. Calyx-tube elliptic in outline, 4-angled, the angles produced into wings, each face deeply wrinkled; calyx-lobes four. Corolla either absent or very fugacious. Stamens 2–8, immersed; anthers oval, dehiscence introrse, filaments short, slender. Pistil—style erect, short; stigma dilated at the apex and fimbriated. Achenes two, plano-convex with an oblique ovoid outline, pale and long. Collected on the Canterbury Plains, near the River Ashburton, in December, 1882.
