Arum idaeum is a woodland plant species of the family Araceae. It is found on Crete.
It has an ovate tuber. [2]
The plant grows 18–22 centimetres (7.1–8.7 in) tall. Stalk base and lower third of petioles is red-veined. Stem is white. Leaves immaculate, and smaller than some coterminous species; ovate-triangular in outline, their lobes horizontally lanceolate, peduncle equal to the leaves. [3]
Spathe is usually almost white, shorter, concolorous, white appendix, far exceeding the spathe, male ring much shorter than female. [3]
Berry is angular, ovate. [4]
It has been recorded at elevations of 1060–1981 m. [1] It often grows under thickets of Berberis cretica . [2]
Flowers June–July. [2]
Together with Arum creticum it has been placed in subsection Cretica, [5] which has been confirmed through genetic testing. They are estimated to have split about 2.2 Mya. No other species are related within 5 Mya. [6]
It was discovered as a species on Mount Ida in 1913–1914 by botanists Paul Cousturier and Michel Gandoger. [2]
