Lilium distichum
Lilium distichum
Lilium distichum is a species of the genus Lilium (Lilium ) in the section Martagon.
Description
Lilium distichum is a perennial, herbaceous plant and reaches a height of 50 to 120 centimeters. The bulbs are broad ovoid and reach a Height from 2.5 to 3 centimeters and a diameter of 2.5 inches to 4 inches. They consist of numerous white, ovate - lanceolate scales that 1.5 to 2 inches long, 4-6 mm wide, loose above the other and at the base are movable.
The hairy stem is papillose, serrated slightly below the whorl and hollow.
Almost all leaves are arranged in the center of the stem to a whorl from seven to nine, often up to twenty hairless leaves. They are obovate - lanceolate to narrowly oblong -round- lanceolate, 5-15 cm long and 1-4 cm wide, tapering towards the base to a winged petiole, taper to a point and are often mucronate. The leaves are dark green and the margin slightly membranous.
Below the whorl there are only one or two membranous leaves, which are also often missing, above found some more freely distributed, small bracts. The bracts are deciduous leaves largely equal, lanceolate, 1 to 2.5 inches long and 3-6 mm wide.
Lilium distichum flowers from July to August, two to twelve nodding or horizontal, scentless flowers in a panicle. The upright -looking flower stalks are 3 to 8 inches long. The six arranged bloom ( tepals ) are lanceolate, slightly beaten, 3.5 to 4.5 inches long and 5 to 13 mm wide, nailed to the approach. At the outer end, they are thicker, they are - with the nectaries - papillose, their color is pale vermilion with purple dots. The lower Tepalenpaar is bent sideways. The stamens are much shorter than the bracts, the orange-yellow stamens are 20 to 25 millimeters long and smooth, the anthers are also orange yellow, linear and up to 10 millimeters long. The ovary is 5-9 mm long and 2-3 mm thick, slightly curved to straight pen twice as long as the ovary. The scar is round and three-lobed.
The seeds ripen in September to 2 centimeters long and 1.5 centimeters wide, inversely egg-shaped and slightly winged seed pods zoom and germinate delayed - hypogeous.
Dissemination
It is native in the People's Republic of China in the provinces of Heilongjiang, Jilin and Liaoning, as well as in South and North Korea and the Russian Primorye.
Lilium distichum preferred sites with weakly acidic, volcanic soil on forest slopes, forest edges or slopes of rivers at altitudes 200-1800 m. In South Korea, it is rare, of the deposits there is a growing broadleaf deciduous trees in under 70 to 80% shade is reported.
System
Lilium distichum was first described in 1915 by Takenoshin Nakai, the specific epithet refers to the lateral spreading of the lower Tepalenpaars. The type takes morphologically a position between their closely related Lilium tsingtauense (flower cup-shaped ) and Lilium medeoloides ( much more recurved bracts ), all species also differ by their distribution areas. Just to the south of South Korea, the areas of Lilium distichum overlap and Lilium tsingtauense, there occur natural hybrids that were formerly classified as a separate species Lilium miquelianum.
