Description
Pamianthe is a small genus of South‑American bulbous perennials. The plants produce umbels of large, fragrant white flowers in spring that resemble daffodils, which has led to the common name “Peruvian daffodil” for at least one species. Pollen grains are relatively large with a coarsely reticulate surface. Seeds are winged and flattened, bearing a brownish‑black seed coat.
Distribution and Habitat
Members of the genus occur in sandy yet rocky habitats across Colombia, Ecuador, Peru, and Bolivia.
Etymology
The generic name honors Major Albert Pam, who introduced plants of this group to the United Kingdom in 1928.
