Xenoscapa is a genus in the Iridaceae family related to Freesia and Crocosmia. There are two species, both in the southern African winter rainfall areas. Plants are small and grow from pea sized corms. The genus name is derived from the Greek words xenos, meaning “strange”, and scapa, meaning “flowering stem”.

Xenoscapa fistulosa, synonymously known as Anomatheca fistulosa, Lapeirousia fistulosa or Ovieda fistulosa, is a South African indigenous species found in the Northern Cape and Western Cape provinces. The small plants, reaching only 3 to 20 cm high, grow on seasonally damp clay or granitic soils on south facing slopes that are often shaded. The leaves lie flat on the ground and flowers are small, white, fragrant, and remain open at night. Flowering is in early spring.
