Pamianthe is a genus of South American bulbous perennials in the Amaryllis family, subfamily Amaryllidoideae.[4] They can be found in sandy, but rocky areas in Colombia,[5] Ecuador, Peru, and Bolivia.[1][6]
Description
[edit]
Generative characteristics
[edit]The plants produce umbels of large, fragrant white flowers in the spring. They resemble daffodils, hence the common name Peruvian daffodil for at least one of the species. Pamianthe pollen grains are large and the surface structure is coarsely reticulate.[7] The winged, flattened seeds of Pamianthe have a brownish-black seed coat.[8]
