Nicole Kalkbrenner and I are currently in Superior, Wisconsin doing some botanical inventory work at a boreal forest restoration. We have been working with local botanists Gary Walton and Paul Hlina. Today, we came across an Aster that I'd never seen.
In examining this plant, it appeared similar to Aster novae-angliae, but without the strongly auriculate-clasping leaves, and with stipitate glands only in the inflorescence.
Gary suggested that maybe this plant could be Aster modestus. Upon keying this plant several times, I am fairly convinced that it is indeed Aster modestus (now known as Canadanthus modestus). Below are additional photos of the stem and leaves.
Note that leaves are not strongly clasping.
Scabrous pubescence on top surface of leaves.
Soft pubescence on bottom surface of leaves.
We believe that this would be a new state record for Wisconsin. I made a collection and plan to submit it to the herbarium at Madison.
Do any of you have any experience with this plant? Any thoughts on this would be welcomed.
