Arum italicum subsp. italicum is a flowering plant subspecies in the family Araceae.
Arum italicum subsp. italicum is a morphologically variable subspecies.[1] Leaves often have various degrees of pale veining or blotching, although uniform green leaves also occur.[1] Spathe limbs are greenish to yellowish white, while the spathe tube is greenish white on the inside (sometimes stained with purple).[2] Spadix appendices are dark yellow.[2]
Plants from the British Isles and the Atlantic coast of western Europe with deep green leaves and winter leaves differing in shape from spring leaves have been treated as a distinct subspecies, Arum italicum subsp. neglectum (F. Towns.) Prime.[2] Differences in germination (epigeal in subsp. italicum, hypogeal in subsp. neglectum) and phenology (subsp. italicum beginning growth earlier) have also been reported.[2] However, there are intermediate forms between the two subspecies, particularly on the European mainland, and there have been proposals to merge the two under subsp. italicum.[1][3]
It in a wide range of habitats between sea level and 1,200 meters.[2] It is native to Europe south of the Netherlands, North Africa, and north and western Turkey, but has is now widely established elsewhere after being introduced as an ornamental plant [2]
Within the genus Arum, it belongs to subgenus Arum, and section Arum.[2] Its relationship with the other subspecies of A. italicum and with Arum concinnatum are unclear.[4]
This subspecies is reportedly hexaploid (2n = 84).[2]
