Lilium bolanderi
Lilium bolanderi
Lilium bolanderi, Syn: Lilium howellii (English Bolander 's lily) is a species of the genus Lilium (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 3.5 to 7.9 cm wide and 2.6 to 5.3 cm high. The loose, white scales of the onion are unsegmented and the longest of them will be from 3 to 5.7 cm long. From the onion plant forms a gray - green stem axis. The roots push out only from the Onion, but not from the stems.
The leaves are arranged in whorls one to six or Teilwirteln to the stem axis. You 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 1.8 to 7.1 cm long and 0.7 to 2.8 cm wide. The edge is always curled and the tip breitlich sharp. The leaf veins run off-axis to the major axis of the leaf.
Lilium bolanderi flowers in July. The inflorescence is umbel- shaped plants with smaller and larger specimen but a panicle or two whorls consisting. There are one to nine single -stalked flowers. The flower stems are 0.8 to 14.2 cm long. The almost bell-shaped flowers are nodding, or nearly horizontal, they do not smell. In general, the flowers are brick to burgundy, but also rare salmon or pale yellow. But always the flowers are dotted maroon or yellowish. The sepals are slightly larger ( about 1 mm longer and wider) bent over as the petals, are both 2 /5 to 4/5 of its length. The petals are 3.0 to 4.5 cm long and 0.7 up to 1.1 cm wide.
The filaments of the stamens run slightly apart, soft between 0 ° and 12 ° from the axis it off, the anthers are reddish or magenta and 0.3 to 0.8 cm long. The pollen are rusty red, orange or yellow. The stamp is 2.1 to 3.5 cm long, the ovary makes 1 to 2.3 cm from it, the pen is green, but rarely reddish or purple.
After flowering, 2 to 4.1 cm are trained long and 1.2 to 2.1 wide capsule fruits that contain 90-210 seeds. The seeds of Lilium bolanderi have two copies of the genome (2n), and the DNA is distributed on 2n = 24 chromosomes. They germinate delayed - hypogeous. From germination to flowering pass usually three years.
Ecology
Lilium bolanderi settled fully sunny locations on heavily drained rocky and gravel bottoms. In autumn and spring, their locations are always damp and cool, in winter cold and snowy, hot in summer and dry.
Phytosociological we find the way in mixed conifer forests, especially in association with Douglas fir ( Pseudotsuga menziesii), like in community with bear grass ( Xerophyllum tenax ).
Lilium bolanderi is pollinated primarily by Red-backed Zimtelfen ( Selasphorus rufus) and Allenkolibris ( Selasphorus sasin ). The species forms hybrids with Lilium rubescens Lilium washingtonianum ssp. purpurascens and the subspecies of panther - lily.
Dissemination
Lilium bolanderi is in the Siskiyou Mountains in northern California and southern Oregon endemic to altitudes 900-1800 m.
System
Ivan Murray Johnston remarked in 1923 that the collection had made the first description of Lilium bolanderi after Sereno Watson, was riddled kelloggii in specimens of Lilium. He argued that the description of Watson was referring to the latter species, and suggested the name Lilium Lilium howellii for bolanderi ago. Arthur Cotton Disbrowe closed but in 1936, that the description of Watson actually not kelloggii related to Lilium and the name Lilium is bolanderi valid. This view has prevailed until today.
