Description

Arisarum simorrhinum is a perennial plant, up to Шаблон:Convert[2] or Шаблон:Convert in height,[3] with the inflorescence being usually shorter than the leaves and with a peduncle stained with purple. The spadix, a rod-like structure bearing the individual flowers, is protected by a special bract (the spathe) shaped as a tube of Шаблон:Convert, wide at the bottom, with purple spotting, and curved upper part, in the shape of a helmet tilted forward. It has sagittate leaves, with a long petiole.[2]

It has no stems, the leaves arise directly from a tuber of Шаблон:Convert, from which rhizomes develop up to Шаблон:Convert and roots up to Шаблон:Convert. It has cordate to hastate-sagittate-shaped leaves, with petioles of Шаблон:Convert, sometimes with small purple spots, winged from the base; the lamina (leaf blade) is Шаблон:Convert, its base is cordate to hastate in shape with acute to rounded lobes Шаблон:Convert.[3]

Inflorescence is Шаблон:Convert with a stalk of Шаблон:Convert, generally flexible and thin; upright spathe with the margins of the bottom joined together forming a closed tube with Шаблон:Convert that ends in the form of a hood, smooth or papillary at the margin, with longitudinal nerve, purple in the apex becoming progressively less pigmented and paler towards the base. The spadix has a sterile terminal part, arched in the upper half and unequal to the lower part, and is situated within the spathe.[3]

Fruit is composed of multiple berries (2-8), greenish and not very fleshy, Шаблон:Convert and 1 to 12 seeds per berry.[3]

Distribution and habitat

Arisarum simorrhinum is native to most of Portugal, western Spain, Morocco and northwestern Algeria. It is a nitrophile and occurs on acidic and basic soils often on disturbed ground and on sandy soils in pasture, clearings in scrub and woodland, on road sides and ditch margins, cultivated land and among rocky outcrops from sea level up to Шаблон:Convert in altitude.[1][2] Records from the Canary Islands, Balearic Islands, Madeira and Tunisia are erroneous due to taxonomic confusion with A. vulgare subsp. subexsertum.[1]
