H. vulgaris (Common Mare's-tail).—The only British species, not uncommon in stagnant water. A .singular plant, with erect, jointed stems, which are un- branched, except at the base, and taper to a point, bearing whorls of 8-12 very narrow leaves with hard tips. The inconspicuous flowers are sessile in the axils of the upper leaves, and are often without stamens. Not to be confounded with the genus, Equisetum (Horse-tail), a plant allied to the ferns, which has a jointed stem and rigid leaves, but bears its fructifica- tion in terminal heads.—Fl. June, Julj'.

M. spicalitni (Spiked Water Mil- foil).—An aquatic plant, rooting in the mud of stagnant waters, and form- ing a tangled mass of slender, much branched stems ; leaves 4 in a whorl, finely divided into numerous hair-like segments, the whole plant being sub- merged, except the leafless, slender spikes of inconspicuous greenish flowers, arranged in whorls, which rise a few inches above the surface. Common. —Fl. July, August. Perennial. 2. M. verticillatitm (Whoiied Water Milfoil).—Differs from the preceding in having the flowers in whorls at the base of the leaves. M. allerniflorimi (Alter- nate Flowered Water Milfoil) has barren flowers, alternately arranged in a short, leafless spike, with the fertile flowers, about 3 together, in the axils of the leave's at its base. The last two are Myrtophyllum Spic.\tum {St'i'ltcd Water Mil/oil). Please note that these images are extracted fr
