I may safely remark that every conservatory without a plant of this lacks a most effective feature in winter - superb in summer from its massive flag-like leaves describing a contour of symmetrical exactness. They rise erect for some distance opposite each other, then bend like two semicircles met over the pot. The flowers appear in winter: they are brilliant orange-scarlet, veined with deeper red. Inside the cup is stamped with maroon over the capsule, which extends up the petals some distance, and terminates in star-like points. Each flower measures about 7 inches diameter, and is in substance solid and leathery, lasting in a fair state of perfection for five weeks. The first set of flowers are generally succeeded by another set, when it is necessary to replace the plant in heat to expand them.
Its cultural wants are simple in the extreme. The temperature of an intermediate house suits it perfectly until the flowers begin to open, when it may be consigned to a sunny aspect in the conservatory. It delights in ample scope for its roots, and thrives well in a compost principally of light flbry loam with a slight admixture of sharp sand and leaf-mould.
