Heracleum sphondylium L.

국표에 없다.

Heracleum sphondylium, commonly known as hogweed or common hogweed, is a herbaceous perennial plant in the carrot family Apiaceae, which includes fennel, cow parsley, ground elder and giant hogweed. It is native to most of Europe, western Asia and northern Africa, but is introduced in North America and elsewhere. Other common names include cow parsnip (not to be confused with Heracleum maximum of North America). The flowers provide a great deal of nectar for pollinators.

Description

Heracleum sphondylium is a herbaceous, flowering plant. It is a tall, roughly hairy plant reaching up to 2 metres (6 ft 7 in) in height. The hollow, ridged stem with bristly hairs arises from a large tap root. The leaves can reach 50 centimetres (20 in) in length. They are once or twice pinnate, hairy and serrated, divided into 3–5 lobed segments.

Heracleum sphondylium is most commonly a polycarpic perennial plant, not a biennial as sometimes claimed. The flowers are arranged in umbels, either flat or slightly convex, 4–25 cm in diameter, usually with 10–25 hairy, somewhat unequal rays, each 2–12 cm long. Each flower has five white or rarely pinkish-white to purplish petals. The central flowers of the umbel have radial symmetry (actinomorphic), while the flowers around the perimeter of the umbel have bilateral symmetry (zygomorphic) since the outermost petals are enlarged. The winged fruits are flattened schizocarps, elliptical to rounded and glabrous, about 7–12 mm long.

The characteristic 'farm yardy' smell or the observation that pigs would eat the foliage and roots of hogweed is perhaps the origin of its common name.

Heracleum sphondylium is smaller than Heracleum mantegazzianum (giant hogweed) and Heracleum sosnowskyi (Sosnowsky's hogweed). It contains some of the same phytophototoxic compounds (furanocoumarins), albeit at much lower concentrations, and there is evidence that the sap from common hogweed can also produce phytophotodermatitis (burns and rashes) in sensitive individuals when contaminated skin is exposed to sunlight.
