Paris quadrifolia; herb-paris can be found in sheltered places, for example in lava fissures. Characteristically a number of shoots rise from an underground rhizome where each shoot has only one flower. Each plant therefore bears only one berry-fruit.
It is an unusual member of the Lily family (Liliaceae), though some botanists have included the genus Paris in a special family: Trilliacae (Birth Root family). More recent though, botanists have made it a member of the Melanthiaceae (Bunchflower family) which now includes the Trillia's as well and is considered to be very closely related to the lily family.
