"Eupatorium sessilifolium", commonly called Upland Boneset or Sessile-leaved Boneset, is a herbaceous perennial plant in the family Asteraceae. This species is native to eastern North America, where it blooms in late summer with white flowers.

Description

Upland Boneset has stems that grow from 50 to over 100 centimeters tall. They are produced from a caudice or short rhizome. The top of the stems, where the branching begins to the flower heads, have short hairs, while the lower part of the stems have no hairs. The leaves are arranged in opposite pairs and are toothed. The leaf bases are rounded and the leaves are sessile (lacking stalks), but they do not clasp around the stem. The foliage is dotted with glands. "Eupatorium sessilifolium" blooms in August and September (July in the southern part of its range), and the small inflorescences are branched and composed of widely-spaced, white flower heads in corymbiform arrays. The heads typically have five or six disc florets per head, and no ray florets.

Upland Boneset has a wide distribution within the eastern and central United States, [http://plants.usda.gov/java/profile?symbol=EUSE3] but is endangered in Minnesota, New Hampshire, and Vermont. It is a threatened species in Michigan, and legally protected in that state. [http://web4.msue.msu.edu/mnfi/explorer/species.cfm?id=13517]
