The derivation and signification of the word Trollius is given under No. 209. It will be at once seen that the name is in no degree applicable to the present plant, which happens from its having been adopted for the European species, when that was the only one known to botanists.

The two species of Trollius which we have figured the European as No. 209, and the Asiatic No. 763, are of far more robust growth, and of bolder character than the American plant now under consideration: those are well suited to the shrubbery, or back-ground of the border, whilst this, from its low stature and early flowers, should occupy a place in its foreground.

We find this plant to be remarkably hardy; indeed this would be indicated by its habitat, which is in shady moist places on mountains, in the state of New York; in some parts of which, the extremes of heat and cold are much greater than in any part of this country.

The Trollius asks not for the slightest care of the florist, other than being planted in the soil, in a situation either shaded or exposed.

Coronilla signifies a little crown, which is prettily represented by the inflorescence of some species of the genus. See No. 226.

Emerus, a name which was originally applied to this shrub, as a generic appellation, is from the Greek, and signifies agreeable. It has been called Scorpion Senna from the old name, Colutæa Scorpioides of Gerard, the pods having swellings, as Parkinson says, like a scorpion's tail.

Although well known, this shrub is not so frequently introduced into prominent situations as it deserves; for, as is rightly observed in that elaborate work-Loudon's Arboretum, The mingling of yellow flowers, with flower buds more or less red, and the elegant foliage, render this hardy shrub a very desirable one for its beauty.' The habit of the shrub, too, would indicate its utility in forming garden hedges, which could be so pruned as to be made very ornamental, and it has the advantage of being exceedingly durable.

It may be grown in any common garden soil, and increased easily by layers, or by seeds, which the plant frequently ripens.
