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]
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe. Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
Anthurium is a genus of about 1,000 species of flowering plants, the largest genus of the arum family, Araceae. General common names include anthurium, tailflower, flamingo flower, and laceleaf.
Arum maculatum is a woodland flowering plant species in the family Araceae. It is native across most of Europe, as well as Turkey and the Caucasus.
Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for Z. aethiopica and calla and calla lily for Z. elliottiana and Z. rehmannii, although members of the genus are neither true lilies of Liliaceae, true Arums, nor true Callas. The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
Lysichiton is a genus in the family Araceae. These plants are known commonly as skunk cabbage or less often as swamp lantern. The spelling Lysichitum is also found. The genus has two species, one found in north-east Asia, the other in north-west America.
Arisaema triphyllum, the Jack-in-the-pulpit, is a species of flowering plant in the arum family Araceae. It is a member of the Arisaema triphyllum complex, a group of four or five closely-related taxa in eastern North America. The specific name triphyllum means "three-leaved", a characteristic feature of the species, which is also referred to as Indian turnip, bog onion, and brown dragon.
Calla is a genus of flowering plant in the family Araceae, containing the single species Calla palustris.
Arum is a genus of flowering plants in the family Araceae, native to Europe, northern Africa, and western and central Asia, with the highest species diversity in the Mediterranean region. Frequently called arum lilies, they are not closely related to the true lilies Lilium. Plants in closely related Zantedeschia are also called "arum lilies".
Arum italicum is a species of flowering herbaceous perennial plant in the family Araceae, also known as Italian arum and Italian lords-and-ladies. It is native to the Mediterranean region. It is also naturalized in Great Britain, the Netherlands, Crimea, Caucasus, Canary Islands, Madeira, Azores, Argentina, and scattered locations in America.
Dracunculus vulgaris is a species of aroid flowering plant in the genus Dracunculus and the arum family Araceae. Common names include the common dracunculus, dragon lily, dragon arum, black arum and vampire lily. In Greece, part of its native range, the plant is called drakondia, the long spadix being viewed as a small dragon hiding in the spathe.
Bucephalandra is a genus of flowering plants in the family Araceae. There are 30 species of Bucephalandra which have been discovered in Borneo and have been formally described by S.Y. Wong and P.C. Boyce. Most of the species are found in Borneo. Bucephalandra are usually found growing as dense mats over stones or rocks in streams or rivers in moist tropical forest.
Orontium aquaticum, sometimes called golden-club, floating arum, never-wets or tawkin, is a species of flowering plants in the family Araceae. It is the single living species in the genus Orontium, which also contains several extinct species described from fossils. O. aquaticum is endemic to the eastern United States and is found growing in ponds, streams, and shallow lakes. It prefers an acidic environment. The leaves are pointed and oval with a water repellent surface. The inflorescence is most notable for having an extremely small almost indistinguishable sheath surrounding the spadix. Very early in the flowering this green sheath withers away leaving only the spadix.
Peltandra virginica is a plant of the arum family known as green arrow arum and tuckahoe. It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba. It is common in central Florida including the Everglades and along the Gulf Coast. Its rhizomes are tolerant to low oxygen levels found in wetland soils. It can be found elsewhere in North America as an introduced species and often an invasive plant.
Arum dioscoridis, commonly known as the Spotted arum, is a plant of the arum family (Araceae).
Arum cylindraceum is a woodland plant species of the family Araceae. It is found in most of Europe except the UK, Russia, Ukraine, Belarus, the Baltic States and Scandinavia, and in Turkey. It is also missing in northwestern France and southern Italy.
Arum orientale is a woodland plant species of the family Araceae. It is found in southeastern Europe as far west as Vienna and in Turkey. Its primary range is Romania, Bulgaria, and southern Ukraine.
Arum sintenisii, known as Sintenis arum, is a flowering plant species in the family Araceae.
Arum italicum subsp. canariense is a flowering plant subspecies in the family Araceae.
Arum italicum subsp. albispathum is a flowering plant subspecies in the family Araceae.
Arum concinnatum, commonly known as the Crete arum, is a flowering plant species in the family Araceae.
