Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

Dasistoma macrophylla (Nutt.) Raf.
Coefficient of Conservatism: 10
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt A-Forb
Status: E
Dasistoma macrophylla W. W. Brodovich

Deciduous forests and forest openings, along larger rivers.

In the absence of flowers, one might confuse the upper part of specimens with the similarly pubescent Aureolaria virginica, although the latter, besides its much larger flowers, usually has slightly longer pedicels and a larger capsule (over 1 cm long, compared to 1 cm or less in D. macrophylla), and is a shorter plant; Dasistoma can be up to 2 m tall. Our other two species of Aureolaria are easily distinguished from Dasistoma by having the pubescence glandular (A. pedicularia) or absent (A. flava).

Usually considered an annual, but vegetative rosettes present at Michigan populations suggest it may sometimes be a biennial (or more likely monocarpic).
