At the lower elevations within its range, Lilium parvum tends to have clear yellow-orange flowers—a form that has been recognized as L. parvum var. crocatum—but perianth parts are redder apically at higher elevations in the Sierra Nevada. The pink-flowered form that is apparently localized at lower elevations in El Dorado County, California, is referred to informally as the ditch lily (O. H. Ballantyne 1983).

Lilium parvum hybridizes sporadically with L. pardalinum subsp. pardalinum at middle elevations (ca. 1200–1500 m) in the Sierra Nevada, resulting in variable swarms of plants with flowers that are intermediate in orientation, size, and perianth recurvature. Hybrids with Lilium kelleyanum are discussed under that species. Lilium parvum is a pollination generalist visited by several species of hummingbirds (family Trochilidae), western tiger swallowtails (Papilio rutulus Lucas, family Papilionidae), pale swallowtails (P. eurymedon Lucas), and various bees (mostly family Apidae).

Lilium parvum ( германски )

Lilium parvum

Lilium parvum ist eine Art aus der Gattung der Lilien (Lilium) in der amerikanischen Sektion.

Beschreibung

Lilium parvum erreicht eine Wuchshöhe von 90 cm bis 170 cm. Die Zwiebeln sind unsegmentiert und rundlich. Sie bilden Rhizome aus.

Der gerade Stängel selbst bildet keine Wurzeln aus. Die Blätter sind lanzettförmig, bis zu 15 cm lang und bis zu 4,4 cm breit. Sie sind in zwei bis fünf Wirteln aus drei bis dreizehn Blättern angeordnet.

Die Pflanze blüht von Juni bis August mit 1 bis 26 waagerechten Blüten in einer Rispe. Die zwittrigen Blüten sind dreizählig. Die sechs gleichgestalteten Blütenhüllblätter (Tepalen) sind leicht gerollt und 3,2 bis 4,2 cm lang. Die Grundfarbe der Blüten ist häuft orange, seltener gelblich, manchmal mit dunklen braunen oder purpurnen Punkten. Insgesamt ist die Farbgebung von Lilium parvum sehr vielfältig und variabel. Jede Blüte enthält drei Fruchtblätter und sechs Staubblätter. Die Antheren sind blass gelb, orange oder magenta die Pollen sind gelblich bis orange. Die Samen reifen in 2,3 cm bis 3,7 cm großen ovalen Samenkapseln.

Verbreitung

Die Art ist in Kalifornien und Nevada heimisch. In niedrigeren Höhenlagen findet sich häufig der gelbe bis orange Typ, in der Sierra Nevada tendiert die Art zu eher roten Blüten. Die purpurne Form findet sich vor allem im El Dorado County.

Lilium parvum braucht einen feuchten Boden, am besten wächst die auf nassen Wiesen oder in Dickichten in der Nähe von Flüssen oder Tümpeln, häufig in der Umgebung von Weiden (Salix spp.) in Höhenlagen zwischen 1400 und 2900 m NN.

Systematik

Lilium parvum bildet in der Natur Hybriden mit Lilium pardalinum und Lilium kelleyanum.

Lilium parvum ( англиски )

добавил wikipedia EN

Lilium parvum is a species of lily known by the common names Sierra tiger lily and alpine lily. It is native to the mountains of the western United States, primarily the Sierra Nevada of California but also with additional populations in northwestern Nevada and southwestern Oregon.[2][3] The plant grows in high altitude forests, sending up flowering stalks during the summer months.[4]

Description

The flowers of Lilium parvum are smaller than those of other lilies, and more bell-shaped than most others. They are yellowish-orange to dark orange-red with lighter orange or yellow centers. The petals are spotted with purple or brown markings. There is a variety that bears lighter pink flowers in the foothills of El Dorado County, California, which is known by the informal common name ditch lily. The plant also readily hybridizes with other Lilium species growing close by.[4]
