Lilium bolanderi , Syn .: Lilium howellii ( English Bolander's Lily) is a species from the genus of lilies ( Lilium ) in the section Pseudolirium . It was named after Henry Nicholas Bolander , a German-American botanist.
description
Lilium bolanderi reaches a height of 30 to 120 centimeters. The small, round, onion is between 3.5 and 7.9 cm wide and 2.6 to 5.3 cm high. The onion's loose, white scales are unsegmented, and the longest of them are anywhere from 3 to 5.7 cm. The plant develops a gray-green stem from the onion . The roots only sprout from the bulb, but not from the stem.
The leaves are arranged in one to six whorls or partial whorls around the stem axis. They stand upright and are usually curved around the stem. The shape is narrow-lanceolate and the leaf surface is blue-green and waxy. The leaves are between 1.8 and 7.1 cm long and 0.7 to 2.8 cm wide. The edge is always wavy and the tip broadly sharp. The leaf veins run off-axis to the main axis of the leaf.
Lilium bolanderi flowers in July. The inflorescence is umbel-shaped in smaller plants , but in larger specimens it is a panicle or two whorls. There are one to nine stalked single flowers . The flower stalks are between 0.8 and 14.2 cm long. The almost bell-shaped flowers are nodding or almost horizontal, they do not smell. As a rule, the flowers are brick-red to wine-red, but more rarely salmon-colored or pale yellow. But the flowers are always maroon or yellowish dots. The sepals are slightly larger (about 1 mm longer and wider) than the petals , both bent over after 2/5 to 4/5 of their length. The petals are between 3.0 and 4.5 cm long and 0.7 to 1.1 cm wide.
The stamens of the stamens diverge slightly, they deviate between 0 ° and 12 ° from the axis, the anthers are reddish or magenta and 0.3 to 0.8 cm long. The pollen is rust-red, orange or yellowish. The stamp is 2.1 to 3.5 cm long, the ovary makes 1 to 2.3 cm assuming the stylus is green, but rarely or reddish purple.
After flowering, capsule fruits 2 to 4.1 cm long and 1.2 to 2.1 wide are formed, which contain between 90 and 210 seeds . The seeds of Lilium bolanderi have two copies of the genome (2n) and the DNA is distributed over 2n = 24 chromosomes . They germinate delayed - hypogean . It usually takes three years from germination to the first flowering.
ecology
Lilium bolanderi lives in full sun on heavily drained rock and scree soils. Their locations are always damp and cool in autumn and spring, cold and snow-covered in winter, and hot and dry in summer.
In terms of plant sociology, the species is found in mixed coniferous forests especially in association with the Douglas fir ( Pseudotsuga menziesii ), often in association with beargrass ( Xerophyllum tenax ).
Lilium bolanderi is mainly pollinated by red-backed cinnamon fever ( Selasphorus rufus ) and allen hummingbirds ( Selasphorus sasin ). The species forms hybrids with Lilium rubescens , Lilium washingtonianum ssp. purpurascens and the subspecies of the panther lily .
distribution
Lilium bolanderi is in the Siskiyou Mountains in northern California and southern Oregon in the amount altitude of between 900 and 1800 m endemic .
Systematics
Ivan Murray Johnston noted in 1923 that the collection from which Sereno Watson first wrote the description of Lilium bolanderi was interspersed with specimens of Lilium kelloggii . He argued that Watson's description was of the latter species and suggested the name Lilium howellii for Lilium bolanderi . Arthur Disbrowe Cotton concluded in 1936 that Watson's description actually did not refer to Lilium kelloggii and that the name Lilium bolanderi is valid. This view has prevailed to this day.
