Description & Remarks

Description Iris palaestina is a perennial geophyte, 8 -13 cm tall that grows solely or in small clumps.  Bulb coverd with papery tunics, it is elongated with several thick fleshy perennial roots. Its stem is short, erected, unbranched, and covered with long linear and twining  leaves that are arranged like a fan. The green leaves are shiny when young and have whitish rims. Its flower is white-cream, rarely bluish (in the southernmost populations), 6-9 cm wide, has 6 perianth segments and 3 lobed pistils. 3 of the outer perianth leaves bend downwards, have dark spots and central yellow vein. These, together with the pistil lobes create 3 tunnels. The inner 3 perianth leaves are small-degenerated and spreading (unlike most other iris species). The fruit that develops in the spring is a long capsule full of dark seeds.

Habitat Rocky lighted batha and herbaceous pastures.

Distribution and abundance Abundant along the central mountain ridge, especially in its western lower part. Large populations are common mainly in the Shefela, in Mt Carmel and in the coastal sandstone ridges (kurkar) of the coastal plain.  The southern location of this species is around Omer near Beer-Sheva, other southern populations occur from Mt Amasa in the south of Judean Mountains to Lehavim and Be’eri in the west. Endemic to Israel and south Lebanon.
