Arum italicum subsp. albispathum is a flowering plant subspecies in the family Araceae.
Description
[edit]Arum italicum subsp. albispathum differs from other subspecies in having very pale, nearly white spathes and pale yellow spathe appendices.[1] This subspecies is reported to have a lower chromosome number, with tetraploid counts in subsp. albispathum (2n = 56) and hexaploid counts in subsp. italicum and subsp. neglectum (2n = 84).[1]
Habitat
[edit]It grows in woodlands from the Caucasus west to Crimea.[1]
Taxonomy
[edit]Within the genus Arum, it belongs to subgenus Arum, and section Arum.[1] Though currently considered a subspecies of Arum italicum, its relationship with the other subspecies of A. italicum and with Arum concinnatum are unclear[2] and it may represent an independent species.[3]
