A. Hooded Or Marsh Skullcap   Scutellaria galericulata

A. Hooded Or Marsh Skullcap - Scutellaria galericulata

In swamps, wet meadows and along streams, Newfoundland to Alaska, south to New Jersey, western North Carolina, Ohio, Nebraska and Washington. Also in Europe and Asia. Flowering from June to September.

There are three additional species of Scutellaria in New York of more limited distribution than the two preceding. The Showy Skullcap (Scutellaria serrata Andrews) with oval or elliptic, coarsely toothed leaves and blue flowers about an inch long in terminal clusters, is the most conspicuous species of the genus in this State. It is found from southern New York southward.

The Larger or Hyssop Skullcap (Scutellaria integrifolia Linnaeus) of about the same range, has thin, linear to oblong, entire, blunt leaves and blue flowers, usually whitish beneath, in terminal racemes, the corolla 1 to 11/4 inches long.
