from the amphibium; and we. ground our authority for confidering it as fuch . on the following circumftances.

3dly, It is feldom or never found in the water, unlefs accidently Overflown.
4thly, Its foliage is very different, the radical leaves much refembling thofe of the Eryfimum officinale.
And, laflly, its feed-veffels are always turgid, and full of feeds, while thofe of the amphibium are ufually abortive.
