Descr. A small shrub, about two feet high, with downy, stout tortuose branches. Leaves nearly a foot long, including the petiole, deeply pinnatifid, coriaceous, dark green above, clothed with rusty down beneath, the segments one to two inches long, broadly linear, dilated at the base, acute at the point, marked with three to four parallel

nerves: petioles four to five inches long, rounded, clothed with rusty down. The young leaves are covered all over with a rich velvety, red tomentum. Head of flowers terminal, moderately large, handsome, surrounded at the base by an involucre of many imbricated, oblongo-ovate leaves or bracteas : thickly clothed with rusty-coloured down. Small, subulate scales are mixed with the flowers. Perianth tubular, cut nearly half-way down into four, narrow-linear, dull orange-coloured, erect laciniæ, hairy without, and bearded at the extremity. Within each of these laciniæ, lodged in a groove, is a linear anther. Germen linear- oblong. Style filiform. Stigma clavate.

The present is one of the many Australian Proteaceæ for which our collections are indebted to Mr. Mackay of the Clapham Nursery; and by him plants were communicated to the Liverpool Botanic Garden, where the flowering specimen here figured was produced in September, 1830. It is a native of the South coast of New Holland, whence the seeds were procured by Mr. Baxter. It is a plant of considerable beauty, and of much variety of colouring.
