(SPEC) Iris longiscapa Ledeb.

1853, Ledebour

Iris longiscapa Ledeb. (Carl F. von Ledebour, 1853, Kara Kum and Kyzl Kum deserts); Section Hexapogon; height 4-8" (10-20 cm); 2-5 flowers, lilac with darker veining; beard whitish; Leaves straight, narrow; Fl. Ross. 4: 93. 1853. Lawrence (1961) notes "When looking over the specimens Caution reference often do not distinguish I. longiscapa represented by the above names, I was impressed particularly by that of Iris longiscapa, one of the Regelia irises. It is a plant 18 to 24 inches tall, sometimes taller in nature, and produces several slender grass-like flexuous leaves along its very slender erect stem. However, the peculiar and distinctive features are in the inflorescence and the flowers. Each main stem bears from three to five flowers that are nearly I. falcifolia. Note last reference for observations; two inches across, and each flower stands on a slender wiry pedicel some two to three inches beyond the spathe valves. The pair of spathe valves themselves are borne on a short peduncle that varies from one half to one inch in length. The specimens, as pressed on the herbarium sheet, suggest horticultural potentials if grown in clumps or small stands by themselves."
"This species has never been illustrated except for a small drawing of one flower in a figure published in Komarov's Flora USSR (vol. 4, t. 34, 1935)";
