Description
Summarize
Perspective
Perennial geophyte. Colms globose.[5]: 129
Purplish-red stems usually 11–18 cm long, but may appear acaulescent. The stem lacks speckes and generally becomes violet-colored toward the base. Scapes are 6–15 cm long, thickening around the lower region of the spathe. Leaves petiolate and hastate, with lateral veins that branch out toward the midsection of the leaf blade upon separation from the middle vein. Basal lobes are linear and come to a point, curling upward. The lower blade of the leaf generally has blackish-brown speckles.[5]: 129 [6]
It can be distinguished from E. rauwolffii by its leaves: its posterior leaf lobes may fragment into secondary lobes, unlike those of E. rauwolfii.[5]: 128
Flower with spathe, purplish, brownish, or reddish black, purplish, or reddish on the inside, green on the outside. Inner surface of spathe is velvety textured. Glabrous 5-8[-10] mm long spadix, with 11–13 mm long pistil. Sterile zone 20-24-35 mm lon long, stamen 7-8[-10] mm long, and sterile flowers 4–5 mm long. Appendix is cylindrical, conical, dark brown or blackish purple, with short stems.[5]: 129
Fruit is grape-like in texture.[5]: 129
Pollen 46.07 μm in diameter, covered with spines 2.37 μm in height.[5]: 130

Taxonomy
A 2021 phenogram placed it closest to E. spiculatum,[5]: 136 but a genetic study has yet to be undertaken (apart from its use as an outgroup).[7]
Distribution and habitat
It is found native in Turkey, Lebanon, and Syria.[8]
It grows on rocky slopes at an elevation of 820–1700 m.[5]: 129
Ecology
Flowers April–May.[5]: 129
History
It was first described as Arum intortum in 1794 by Joseph Banks and Daniel Solander in Volume II of the 2nd edition of Alexander Russel's The Natural History of Aleppo.[6][9]
Uses
A 2023 study aimed at metabolite profiling was the first mass spectrometry of the species, and identified the extract of its flowers as a strong cholinesterase inhibitor.[10]
Toxicity
A case of poisoning occurred in the countryside of Edessa when a girl consumed about 50 g of the corm of the plant raw,[a] developing SOB, a swollen tongue, a burning sensation in the mouth, hypersalivation, and eventually aphthous lesions and a necrotic wound on the underside of the tongue.[11]
