Heracleum maximum,
cow parsnip (also known as
Indian celery,
Indian rhubarb or
pushki) is the only member of the genus
Heracleum native to
North America. Its classification has caused some difficulty, with recent authoritative sources referring to it variously as
Heracleum maximum or
Heracleum lanatum, or as either a subspecies,
H. sphondylium subsp.
montanum, or a variety,
H. sphondylium var.
lanatum, of the
common hogweed (
H. sphondylium). The classification given here follows ITIS.
