Thalictrum pubescens Pursh
Common Name: TALL MEADOW-RUE, LATE MEADOW-RUE, KING-OF-THE-MEADOW
Coefficient of Conservatism: 3
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Nt P-Forb

This species of moist to wet meadows, thickets, open woods, and shores is admitted to our flora with some skepticism. The sparse distribution is widely scattered, and some of our collections are at the upper limits for measurements of this species, which replaces T. dasycarpum as the common meadow-rue immediately to the east of Michigan. The filaments are normally strongly clavate, often becoming broader than the anthers, while in T. dasycarpum they are filiform (often kinky and tangled at maturity) or clavate but still distinctly narrower than the anthers. There is a tendency for the anthers to have an inconspicuous apiculus, as compared to the more prominent one of T. dasycarpum.
