Lilium stewartianum ( Chinese 单 花 百合 , Pinyin Dàn huà băi hé ) is a plant species from the genus of lilies ( Lilium ) in the Asian section . The species was named after John Stuart, 3rd Earl of Bute .
description
Lilium stewartianum is perennial and 20 to 50 centimeters high. The egg-shaped onion reaches a diameter of around 2 centimeters and is composed of white, egg-shaped-lanceolate scales.
The linear foliage leaves are distributed along the green, occasionally dark red spotted stem, are 2.5 to 7 centimeters long and 3 to 4 millimeters wide, have one nerve and are weakly papillary at the edge .
The plant blooms in July to August with a terminal, nodding and fragrant single bloom. This is stalked and the stem is about 2 inches long. The six inverted-lanceolate to elongated-round bloom cladding sheets ( tepals ) are greenish-yellow, deeply dark red, 4.5 to 5 centimeters long and 7 to 9 millimeters wide. The stamens are up to 3 inches long. The ovary is upper constant and violet, the stylus is 2 to 2.2 centimeters long and has a diameter of about 3 millimeters.
After flowering, a brown, elongated-round to elliptical capsule fruit forms which is ripe in October, it is 2 to 2.5 centimeters long and 1.5 to 2 centimeters thick.
distribution
Lilium stewartianum is endemic in northwest China's Yunnan Province , from the mountains around Lijiang to the Zhongdian Plateau. There it grows at altitudes between 3600 and 4300 m on forest edges and in open grassland in rocky locations on limestone soils. It is unclear whether there is also a population in the Tibet Autonomous Region . Isaac Bayley Balfour (1853–1922) made an initial description of the species in 1922 without a holotypical specimen available to him. Instead, he was guided by an earlier Chinese description of a find from Tibet. The specimen found is archived in the Kunming Botanical Garden , today only one capsule and one onion remain. Specimens pulled from the capsule look very similar to Lilium habaense , but have unusually large flowers. It is still unclear whether it is actually Lilium stewartianum or possibly a hybrid Lilium stewartianum x habaense .
