Discussion | Throughout most of modern botanical history this Chinese lily has been known as Lilium tigrinum, but recent nomenclatural reassessment affirms that Thunberg’s description, published sixteen years earlier than Ker Gawler’s, applies to this species. Though many North America species are known vernacularly as tiger lilies, the name is properly applied only to this one. Along with L. candidum, it is considered to be among the earliest domesticated lilies (H. D. Woodcock and W. T. Stearn 1950), no doubt because it is handsome, easy to grow, and the bulbs are edible and substantial. It is widely planted in North America, usually as a sterile triploid that is best propagated from the bulbils. Perhaps the hardiest garden lily, Lilium lancifolium is a widespread but sporadic garden escape, and roadside lilies near habitation in eastern and northeastern North America are often this species. Despite its general use in gardens, it seems to be naturalized only in the better-watered eastern portion of the continent. In North America, the tiger lily is rather easily diagnosed by its truly lanceolate and widely sessile alternating leaves that bear dark bulbils on the upper stem. The mature buds are usually high-shouldered and taper rather evenly to a flattish apex with three greenish, terminal, rounded processes. No native lily consistently displays any of these features.

I. M. Johnston (1923) noted that 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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
