The term liveforever may refer to the longevity and hardiness of some plants in the wild. The name of the subgenera Stylophyllum is an allusion to the pencil-shaped leaves of the type species, Stylophyllum edule, now known as Dudleya edulis. The name of the subgenera Hasseanthus was in honor of Dr. Hermann E. Hasse, a surgeon and collector of California flora. Dudleya virens subsp. hassei is also named after him. Nomenclature English: Dudleya, liveforever Spanish: siempreviva, mezcalito Tiipai: milhka’mey (wide-leaf); milh kajmila (narrow-leaf) Paipai: awi mielh Reproductive biology Pollinators and flower morphology The pollinators of Dudleya are mostly hummingbirds and bees, although this has been inferred in some species only from flower morphology. The genus exhibits a wide array of diverse flower varieties, even within species complexes. The flowers are mostly hermaphroditic, although some individuals may have sterile anthers. Plants with long, tubular, reddish flowers, mostly in the subgenus Dudleya, are adapted towards pollination via hummingbirds, while short, spreading, yellow flowers favor pollination by insects. Despite the evolution of long flowers towards hummingbirds, the long flowers also show no performance disadvantage in pollination environments exclusively composed of insects. While the long flowers may provide an evolutionary advantage for more effective pollination, more energy is required to produce the larger amounts of floral tissue.
