Nemastylis geminiflora, commonly known as prairie celestial, celestial,[1] prairie pleatleaf,[2] or celestial lily[3] is a perennial herb in the Iridaceae (iris) family. It is native to the south-central area of the United States.

Description

[edit]

N. geminiflora grows to a height of 30 centimetres (12 in), sometimes taller, with stems growing from a bulb deep in the ground. Each stem is clasped by 1 to 4 narrow, linear leaves. The leaves are long and narrow, up to 11 centimetres (4 in) wide, folded lengthwise near the base and pleated along the veins or flat near the top.[4] Flowers are 6.5 centimetres (2.6 in) long, in the shape of a star with 6 blue-violet or blue pointed petals and sepals. 1 or 2 flowers emerge from a common spathe, or sheath.[3] Each flower lasts only one day, opening up in the late morning and closing mid-afternoon.[5]

Distribution and habitat

[edit]

The plant is native to Alabama, Arkansas, Kansas, Louisiana, Missouri, Mississippi, Oklahoma, Tennessee, and Texas.[2] The plant occurs in limestone glades, prairies, and rocky slopes.[3]

Ecology

[edit]

N. geminiflora is pollinated by bees, flies, and other insects, which gather nectar from the flowers. Flowers appear in April and May.[6]
