Among the aquatics (page 34, Plate VIII) we have already acquainted ourselves with a curious connection of this pretty plant. U. cornuta we find in peat bogs; it does not bear any bladders and is therefore less extraordinary in its movements. On a slender pedicel it bears from two to four large flowers about one inch long, which have a helmet-shaped lower lip and long curved spur. They are bright yellow, delicate, and very fragrant. In fact, Mr. Burroughs regards this to be the most intensely fragrant wild flower of our country.
