Rhodohypoxis is a small genus of tuberous flowering plants in the family Hypoxidaceae, native to southern Africa (South Africa, Lesotho, Swaziland).[1] The small flowers, no more than 15 cm (6 in) high, are constructed so that their centres are not visible. Some species are in cultivation.

Description and distribution


Rhodohypoxis species grow from small tubers. They flower in the summer and die down in the winter. When in flower, they are typically 2–15 cm (0.8–5.9 in) tall. The flowers are white, pink or red; the bases of the tepals bend inwards, so that the stamens and ovary are not visible. Rhodohypoxis species are found in the eastern part of southern Africa, particularly in the Drakensberg mountains in the province of KwaZulu-Natal and Lesotho. This is a region of summer rainfall with relatively dry winters.[2]

Species[3]

  2. Rhodohypoxis deflexa Hilliard & B.L.Burtt - Cape Province, Lesotho, KwaZulu-Natal
  3. Rhodohypoxis incompta Hilliard & B.L.Burtt - Lesotho, KwaZulu-Natal
  4. Rhodohypoxis milloides (Baker) Hilliard & B.L.Burtt - Cape Province, KwaZulu-Natal
  5. Rhodohypoxis rubella (Baker) Nel - Cape Province, Lesotho, KwaZulu-Natal
  6. Rhodohypoxis thodiana (Nel) Hilliard & B.L.Burtt - Lesotho, KwaZulu-Natal

Cultivation


Rhodohypoxis baurii is not uncommon in cultivation. It is not reliably frost hardy, so is often grown in pots, protected in the winter. Various colour forms are available under cultivar names, e.g. 'Ruth' (pure white), 'Allbrighton' (pink) and 'Douglas' (red). Some other species, such as R. milloides, and hybrids with Hypoxis species are also grown.[2]

Rhodohypoxis es un pequeño género de 6 especies perennes y bulbosas de la familia Hypoxidaceae, nativas de Sudáfrica, particularmente de la región de las montañas Drakensberg. Está estrechamente relacionado al género Hypoxis. De hecho, las especies de Rhodohypoxis fueron dispuestas en el género Hypoxis hasta 1914, cuando Gert Cornelius Nel reconoció que estas plantas herbáceas con flores de color rosado eran diferentes de sus contrapartes de tépalos amarillos y perigonio con forma de estrella. Nel estableció entonces el género Rhodohypoxis para acomodar las plantas de "Hypoxis" con flores blancas, rosadas o rojas. En aquel momento, este taxónomo reconoció únicamente dos especies, R. baurii y R. rubella. El prefijo "Rhodo" se refiere al color rosado de las flores de este género, e "Hypoxis" a la similitud estructural con las plantas de este taxón.
