Arum concinnatum is a tuberous herb in the Araceae family, native to the East Aegean Islands, Greece, Crete, and Turkey. It blooms in early autumn, with a rhizomatous tuber measuring 7-15 cm in length and 1.5-3.5 cm in thickness. The plant features a terete petiole and a leaf blade that is sagittate-hastate to oblong-sagittate in shape, with a semi-glossy, dark green surface and silver-grey blotches. The inflorescence has a strong odor of stale urine and is shorter than the leaves. The spathe is 16-29 cm long, with a pale to mid-green exterior and a pale greenish-white interior. The spadix is 9-27 cm long, with an appendix that is conic-cylindric to clavate-cylindric in shape and colored dull ochre-yellow to pale creamy yellow. It thrives in ditches, wet banks, and undisturbed olive groves, often in high abundance.
