" Low smooth and weak," says Gray, when speaking in his Manual of Circaea alpina, and " common northward".

The little heart-leaved plant is said to be not over eight inches in height, and of the dozen specimens that, nearly a year ago, I found in one saucer-shaped damp depression, about the width of a wash-tub, none were that.

Pressed, it makes a very pretty and manageable tenant of the herbarium, and shows better there; is less likely to be overlooked than in the shady woods where it prefers to grow. My knowledge of the plant is confined to the few specimens above mentioned, which were in flower and fruit near this city on the 3d of last September.

A less shy plant, but more rare, perhaps, is the diminutive Euphorbia peplus. A large yard on West Main Street in this city, is so largely filled with it that it would be certain to detain the plant hunter, should his eye catch sight of it. It is, doubtless, quite a delicate herb; indeed, it was so spoken of by the lady occupying the house in the lot. Blue grass, if allowed freely to grow, would perhaps crowd it out; and I noticed that it preferred to follow the but seldom used carriage way, and spread under shrubbery and where the ground inclined and was so broken as to easily receive the yearly crop of seed.

I was told that a few came to view the plant, and that it could not be found elsewhere in the city. This latter belief is a slightly mistaken one, as I have seen single specimens of it on the footway margins of several of the streets, and in florists' yards. Except where massed, as in the yard mentioned, it might at a distance be easily mistaken for Oxalis stricta, its general height and color being similar, or for a nearly erect, broad, and thin leaved form of Polygonum aviculare.
