Allium struzlianum Ogan: Red Data Book of Armenia

VU B 1 ab(ii,iii,iv) + 2 ab(ii,iii,iv)

Category. Vulnerable species. Endemic of Armenia. The area of distribution is severely fragmented. The extent of occurrence is less than 20000 km2, the area of occupancy is less than 2000 km2. The species faces decline of the extent of occurrence and the area of occupancy caused by anthropogenic factor. It was not included in the first edition of the Red Data Book of Armenia. It is not included in the Annexes of CITES and that of the Bern Convention.

Description. Bulbous plant. Stem 30–50 cm. Leaves 2–7, linear, acutate, reflexed. Inflorescence hemispherical. Perianth stellate or broadly infundibular–stellate; segments silvery–white, pinkish–lilac or pink with pinkish–lilac or greenish midrib, lanceolate, acute. Decorative plant.
