The Early Field Scorpion Grass (_Myosotis collina_) belongs to the order _Boraginaceæ_--a family of (usually) hairy herbs with alternate leaves and one-sided spikes or racemes of showy flowers. The flowers have a five-lobed calyx and corolla, five stamens, and a fruit of four nutlets. It is in the same genus as the familiar Forget-me-not, and, in fact, somewhat closely resembles that plant, which is often confused with certain species of Scorpion Grass. It is a slender, more or less prostrate herb, with blunt oblong leaves; and minute, bright blue flowers which are at first hidden among the leaves, but afterwards exposed by the lengthening of the stem. The flowers have very short pedicels; and are in long, slender, leafless, spikelike racemes, with a single flower some distance down, in the axil of the highest leaf. The popular name of Scorpion Grass has been given on account of the characteristic arrangement of the flowers when in the bud, these being then tightly coiled in a scorpoid fashion. In order that the present species might be distinguished from allied plants, we should note that the pedicels are shorter than the calyx; that the calyx is furnished with hooked bristles, and is open and swollen when the fruits are formed; also that the tube of the corolla is very short. The Early Field Scorpion Grass is very common on dry banks. Its stems vary from about four to ten inches long, and the flowers appear during April and May. [Illustration: THE BLACK BRYONY IN FRUIT.] The Wood Loosestrife or Yellow Pimpernel (_Lysimachia nemorum_) of shady waysides and woods is a member of the _Primulaceæ_ or Primrose family. It is altogether a pretty little plant, much like the Scarlet Pimpernel in general appearance, but somewhat larger and more glossy. It has a prostrate, spreading stem, often tinged with red; and opposite, oval, acute leaves with short stalks. The flowers are yellow, usually a little more than half an inch in diameter, with a spreading corolla. They are axillary, placed singly on very slender peduncles, and have very narrow sepals. This species flowers from May to August. The Perennial or Dog's Mercury (_Mercurialis perennis_), of the _Euphorbiaceæ_ or Spurge family, is one of our earliest spring flowers, and may be seen in abundance on almost all shady waysides, in bloom from March to May, and growing from six to eighteen inches high. The minute green flowers, which have three sepals and no petals, are in racemes or spikes that grow from the axils of the upper leaves. They are unisexual; the staminate flowers in slender racemes, with several erect stamens; and the pistillate ones in short, few-flowered spikes, with a two-celled ovary, two styles, and a few imperfectly formed stamens.
