Flower of the Day: Winged Monkeyflower

Mimulus alatus; Phyrmaceae (lopseed family)


(The genus Mimulus is also placed in the figwort family by some authorities.)

Winged monkeyflower is found in the eastern US, and is listed as a plant of special concern in Connecticut, threatened in Iowa, endangered in Massachusetts, probably extirated in Michigan, and rare in New York.

It might not be rare in Maryland, but I consider myself lucky to have found it. I knew exactly where to look, and when, and there it was.  But I was hiking with Steve, who doesn’t like to stand around for half an hour while I photograph the same plant over and over, so I took a few very quick pictures and decided to come back a few days later for a more leisurely photo shoot.

When I say exactly, I mean exactly – I know exactly which fallen log over which seasonal stream these plants stand by.  And when I went back a few days later – nothing.  No flowers, anyway.  Top part of the plants missing, too.  Deer browse.

Always take the time to get a few good pictures, for you never know what the future holds.

Anyway, this is the sister plant to the Aug 1 FOTD (Allegheny monkeyflower). A few characteristics set them apart:

  • The leaves of M. alatus have long winged petioles, while the leaves of M. ringens are sessile.
  • The flowers of M. alatus have very short pedicels, while those of M. ringens are very long.
  • M. alatus flowers tend to be pink; M. ringens flowers tend to be light purple.

Of the 91 species of Mimulus listed in the USDA plants database, these are the only two found in Maryland.
