description
Lilium sherriffiae is a perennial , herbaceous plant and reaches heights of between 35 and 90 centimeters. The white, egg-shaped to narrow-egg-shaped onion has a diameter between 2 and 3 centimeters and is around 2.5 centimeters high. The approximately twelve pointed scales are lanceolate to ovoid-lanceolate, up to 8 millimeters wide and 2 to 3 millimeters thick.
The stem is hairless and tinted purple and has only weak roots at the base above the bulb. The internodes are up to 9 inches long. The sessile, linear to narrowly lanceolate-linear foliage leaves are 3 to 13 centimeters long, six to eight nerved and the midrib on the underside is slightly protruding.
In June, the species usually blooms with a single terminal flower , rarely with two flowers. The narrow, bell-shaped, nodding flowers are on 2 to 7 centimeters long, hairless, green flower stalks. The bracts are slightly bent back and of approximately the same shape. The bracts of the outer circle are 5.5 inches long and 1.4 to 1.7 (rarely up to 2) inches wide, narrow, elongated-round, elliptical and hairless; those of the inner circle are elongated-round elliptical and 1.8 to 2, rarely up to 2.5 centimeters wide. They are all of a brown-purple basic color and on the outside, like a mosaic, golden yellow and green piebald, also on the inside in individual places.
The slender stamens are 1.8 to 1.9 centimeters long, 1 millimeter thick at the base and hairless. The linear anthers are 13 millimeters long and 2 to 2.5 millimeters thick, the pollen is golden in color. The cylindrical ovary is 11 mm long and 3 mm wide, the hairless stylus 23 millimeters long and club-shaped, the scar 2 millimeters long, 3 to 4 millimeters wide and three lobed.
distribution
The species occurs in the northeastern districts of Bhutan , in Bumthang and Trashiyangtse as well as in Nepal. It grows at altitudes between 2700 and 3800 meters, near river banks on open grassland on slopes or under trees, often under willows , on sandy soils.
Botanical history
Lilium sherriffiae was first collected on May 23, 1949 by JH Hicks and Elizabeth Sherriff on the basis of a single plant near Lao in the Trashiyangtse district. On July 22 of that year, Frank Ludlow and George Sherriff found a large population of several hundred plants near the Dhur River in the Bumthang district. Based on the herbarium he had brought with him, William Thomas Stearn described the species in 1950 and named it Lilium sherriffiae in honor of the discoverer Elizabeth Sherriff . Some plants were grown from seeds brought along in Great Britain, including in the Edinburgh Botanical Gardens. However, it disappeared from human culture again by 1960 at the latest.
