Proiphys is a small genus of herbaceous, perennial, bulbous plants belonging to the family Amaryllidaceae (subfamily Amaryllidoideae), within the order Asparagales. The genus comprises five accepted species distributed across Southeast Asia, Papuasia (New Guinea), and northern and northwestern Australia.
Plants in this genus grow from bulbs and produce strap-shaped leaves typical of the Amaryllidaceae family. They bear showy, white, funnel-shaped flowers that make them attractive as garden ornamentals, though they are not widely cultivated. The flowers and foliage are considered garden-worthy characteristics across the genus.
Among the best-known members are Proiphys amboinensis, commonly called the Cardwell Lily, which occurs from Thailand and the Philippines through Sulawesi, the Lesser Sunda Islands, Papuasia, and into Queensland and Western Australia; and Proiphys cunninghamii, the Brisbane Lily or Moreton Bay Lily, native to Queensland and New South Wales. Other species include Proiphys alba from New Guinea and northern Australia, Proiphys infundibularis from Queensland, and Proiphys kimberleyensis from northwestern Australia.
Distribution
Proiphys species are native to Southeast Asia (Thailand, the Philippines), Sulawesi, the Lesser Sunda Islands, Papuasia (New Guinea), and Australia (Queensland, New South Wales, Northern Territory, and Western Australia). The genus spans a range from tropical Southeast Asia south through the Pacific islands to the Australian continent.
Cultivation
The flowers and leaves of Proiphys species make them desirable garden subjects, though they are not widely cultivated as ornamental plants.
