Lilium bolanderi

Lilium bolanderi is a species of lily of western North America, known by the common name Bolander's lily. It is a perennial herb growing a waxy, erect stem that approaches a meter in height. It originates from a scaly, elongated bulb up to about 7 centimeters long. The wavy oval leaves are located in several whorls about the stem, each waxy green and up to 7 centimeters in length. The inflorescence bears up to 9 large, nodding lily flowers. The flower is bell-shaped with 6 red tepals up to 5 centimeters long and marked with yellow, purple, or darker reds. It often hybridizes with other lilies, producing a variety of forms, colors and patterns. There are 6 stamens with anthers sometimes nearly a centimeter long and a pistil which may be 4 centimeters in length. The flowers are pollinated by Allen's and rufous hummingbirds, Selasphorus sasin and rufus, respectively.[1]

The lily was named after the California botanist Henry Nicholas Bolander.

Notes

Comments

Lilium bolanderi Watson was based on a mixed collection including L. kelloggii, and he argued that Watson intended the name to apply primarily to the latter species. Thus he proposed the name L. howellii for this diminutive, red-flowered, serpentine endemic. A. D. Cotton (1936) correctly concluded that Watson’s description applied primarily to the specimens here called L. bolanderi, and this view is now widely accepted. 

 Lilium bolanderi hybridizes with L. rubescens, L. washingtonianum subsp. purpurascens, and subspecies of L. pardalinum.  Bolander’s lily is primarily pollinated by Allen’s and rufous hummingbirds (Selasphorus spp., family Trochilidae).
