[Illustration: FIG. 4.—THE FLOWER OF THE COMMON BUTTER-CUP.] [Illustration: FIG. 5.—FLOWER AND RIPE CARPELS OF THE BUTTER-CUP.] The plant from which my drawings were made was a common buttercup, _Ranunculus acris_, which my readers will easily recognise if they should meet with it, by its erect flower-stem, deeply cut leaves, and fibrous root. Another species (_Ranunculus bulbosus_) is, also, sometimes called the buttercup; but it is easily distinguished by its bulbous root. Both these, and several other species, have deeply cut leaves, which somewhat resemble the feet of a bird, and hence the name of crowfoot is often applied to them. Others, such as the greater spearwort (_Ranunculus lingua_), have long tongue-shaped leaves. In all, the footstalks of the leaves are somewhat folded round the stem at their base. Such of my readers as reside in the country will find it very amusing to gather all the kinds of crowfoot, buttercup, goldilocks, and spearwort, they can find in the fields and lanes; and after having compared the flowers with the description I have given, to try to find out the specific names, by comparing the other particulars with the descriptions in Hookers or Lindley’s British Botany, or with the plates and descriptions in the new edition of Sowerby’s English Botany. In a short time they will not want these aids, but will be able to name the plants at once, and to tell in what they differ from each other by memory. I shall never forget the pleasure I once had in finding out the name of a plant myself. I happened to be waiting for Mr. Loudon, (who had gone to examine some new pines and firs,) in the pleasure-grounds of a villa, just opposite a small pond, which was covered by some white flowers that I did not know. The flowers were small, but very beautiful, and as they shone with almost a metallic lustre in the sun, they looked like a silvery mantle thrown over the water. I was curious to know what they were, and having got one with some difficulty, and by the help of my parasol, I began to examine it botanically. The leaves at first told me nothing as to the genus, for the upper ones were nearly round, and only slightly cut into three lobes, while the lower ones were almost as much divided as fennel; but on examining them closely, I found their stalks sheathed the stem at the base. This gave me the first idea of the plant being a Ranunculus, for I remembered the leaves of that genus were stem-clasping. I then looked at the plant again, and wondered at my own stupidity in not having before observed its resemblance to the genus. There was the cup-shaped flower of five petals, the green calyx of five sepals, the numerous stamens and
