Abstract
We examined 104 species (13%) of the approximately 784 species of biotically pollinated plants native to Hawai'i and found 14 (13.5%) that have an ultraviolet (UV) floral pattern. However, detailed examination revealed that 32% of the Hawaiian strand species have UV floral patterns, whereas only 8% of the upland species did. All of the flowers with UV patterns measured 1 cm or more in diameter and all but two appear yellow to humans. We discuss several possible explanations for the apparent paucity of UV floral patterns in the native Hawaiian upland flora.
