Dorema sabulosum Litv.

Local name:

  • Russian: Дорема песчанная - dorema pesčannaja
  • Uzbek: Ilyan

Chromosome numbers: 2n = 22 (Takhtadzhyan 1987; Schulz-Gaebel 1930).

Description and morphology: Perennial large monocarpic herbs with a woody deep pivotal root. Stem: thick, strong pyramidal, ramified from the middle. Leaves: lower – rosette-like on short petioles, greyish pubescent with triangular large leaf (up to 12 cm long, 3.5 cm wide), tri-pinnatisected into lanceolate, accuminate leaf plates; middle – sessile, leaf base extends along the stem. Umbels (8–12 flowered), alternate or distributed in couples on short petioles. Calyx segments non-dentate. Flowers: bisexual; on short thin pedicel (5 mm long) with 5 free, yellow, oblong-oviform attenuated to the top petals. Ovary densely pubescent.

Reproduction: Flowering: April. Fruit maturation: May–June. Fruit: large (up to 15 mm long), elliptic, usually spirally incurvate (curved) with whitish margins, narrow achene, divided into ribbed thin mericarps. Pitch channels superficial, furrows singularly arranged.

Pastoral importance: Contradictory data. Satisfactory spring green forage for sheep, goats and camels (Nechaeva and Prihodko 1952). Larin (1937) indicates that it is poorly grazed, mostly by camels. Erejepov (1978) describes it as a poisonous plant.

Economic interest: Milky latex from the roots used as diuretic and for head and respiratory organs. Tincture from green stem used as a remedy for head and heart illnesses.

Habitat: Frequently occurs in the desert on hillocks and fixed sands.

Distribution: Endemic. Karakalpakistan, Karakum, Kyzylkum and Sundukli deserts.
