Lilium pardanthinum is a species of plant in the genus Lilium . It is in the border region in the northeast of the province of Yunnan in the People's Republic of China endemic .
features
Lilium pardanthina is a perennial , herbaceous plant . It reaches heights of growth between 25 and 65 centimeters, in extreme cases up to 90 centimeters. The number of chromosomes is 2n = 24. The seeds germinate above ground (epigeic).
onion
Lilium pardanthinum lives geophytically and forms underground onions . These are approximately egg-shaped and are between 2.5 and 3.5 centimeters high and 2 to 3.5 centimeters in diameter. They are white and turn pale brown when dried. As is typical with Nomocharis , the onions are made up of oval-lanceolate onion scales. The roots are adventitious roots , most of which arise from the onion, but partly also directly from the stem axis .
leaves
The stem axis is erect and papillae . The leaves are in 4 to 8 whorls , the position of the leaves changes towards the tip . The leaf shape is elliptical or lanceolate. The leaves are about 1.0 to 1.4 inches wide and 5 to 7 inches long. The blade is pointed at the tip and hairless on both sides.
Flowers and fruits
The plant blooms from May to July with one or more six-fold, nodding flowers . The inflorescence is umbrella-shaped and white or pink. The outer three tepals are narrowly egg-shaped and between 2.5 and 3.5 inches long and 1.5 to 2.0 inches wide. They are entire and pointed at the tip. The three inner tepals are broad-egg-shaped to almost round and between 2 and 3 inches long and 2 to 3 inches wide. They are fringed-slit on the edge and studded with purple dots, which enlarge into broad spots towards the tip. The tip is pointed.
The yellowish-white stamens are fused at the base to form a fleshy cylinder and about 6.5 to 7 millimeters long, they taper abruptly towards the top. The ovary measures between 6 and 8 millimeters in length and 2 to 3 millimeters in diameter. The stylus thickens to the top and is approximately the same length as the ovary (6 and 8 millimeters). The scar is head-shaped and three-lobed on the surface. The nectaries are purple, fleshy, pillow-shaped clusters of cells. The pollen has a net-like exine and measures an average of 70.5 × 47.0 micrometers.
The fruit ripening is completed between July and September. The elongated egg-shaped capsule fruits are pale brown. They are about 2.5 inches long and about the same width. You are jaded sex-angled.
Distribution and habitats
distribution
Lilium pardanthinum is endemic to a small area . Populations of the species can be found in the border region between the northwest of the Chinese province of Yunnans and Sichuan .
Habitats
Lilium pardanthinum prefers to grow on the edges of forests and on grassy slopes. It can be found at altitudes of 2700 to 4100 meters.
Botanical history
Lilium pardanthinum was collected by Pierre Jean Marie Delavay in the Cangshan Mountains near Dali in 1883 . Adrien René Franchet described the species in 1889 as a type of the new genus Nomocharis as Nomocharis pardanthina . René Maire collected some Nomocharis in the neighboring mountains of Lijiashan , which Augustin Hector Léveillé described as Nomocharis mairei in 1913 . In 1979 Joseph Robert Sealy realized that it was a form of Nomocharis pardanthina f. puctulata acted. In 2016 the species was recombined as Lilium pardanthinum with the incorporation of the genus into the lilies by Gao .
The specific epithet pardanthinum is made up of the ancient Greek παρθος (= pardos) in German the leopard or panther and άνθος (= anthos) the flower. This refers to the leopard skin-like spots on the tepals.
Systematics
In addition to the nominotypical taxon , the form Lilium pardanthinum f. punctulata recognized.
When cultivated , Lilium pardanthinum forms hybrids with Lilium farreri , which are called Nomocharis x finlayorum , which suggests that the two species are closely related.
Culture
Lilium pardanthinum bulbs reached the Royal Botanic Garden Edinburgh as early as the end of the 19th century , where they first bloomed in 1914 and can still be seen today. Despite the attractive flowers, the species is rare in culture.
