One translation of the Latin term 'Iris regis-uzziae' in Hebrew is אִירוּס טוּבְיָה [5]

It is a bulbous perennial.

It was first described in notes from Royal Botanic Garden Edinburgh in 1978 by Prof. Naomi Feinbrun-Dothan (an Israeli botanist).[6] She also then described it in The Iris Year Book 1979.[7]

It can be seen in Jerusalem Botanical Gardens.[1][8] It also can be found at Kew Botanic Gardens, but confusingly they call it 'Jordan Iris'.[9]

Description

Iris regis-uzziae has 1–2 pale-blue, lilac or very pale green flowers.[7] They can also be described as blueish-white.[10]

The falls are about 4.5 cm long.[7] It flowers in early spring in January and February, after the leaves have emerged from the ground.[10] The leaves have thich white margin. They reach about 4 cm when the bulb flowers.[7]

The 3.5–4 cm long greyish-brown oblong bulbs,[7] grow about 7–12 cm (3–5 in) below the surface.[10] They have fleshy-like roots.[7]

It has 4 mm long globose seeds.[7]

Compared to Iris aucheri, it is smaller, has fewer leaves and has a yolk-yellow coloured crest. Compared to iris nusairiensis, it has highest leaf is not dilated and its yellow crest has a white margin.[7]

Biochemistry

As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[11] It has a chromosomal count of 2n = 20,[12] or 2n = 22 (Feinbrun 1978).[13]

Native

It was found on north or west facing rocky slopes [10] of Southern Jordan and Negev in Israel.[10]
