says, "I found it particularly abundant, and I afterwards found it in West Bothnia." The French call this plant La Montie; the Germans, Die Quellenmonti. It is the Bronminnende montia of the Dutch.

ORDER XXXIV. PARONYCHIEÆ.-KNOT-GRASS TRIBE. Sepals usually 5; petals 5, minute, inserted between the lobes of the calyx, sometimes wanting; stamens varying in number, opposite the petals if equalling them in number; ovary not combined with the calyx; pistils 2-5; fruit 1-celled; opening with 3 valves, or not opening. The Knot-grass Tribe is composed of small shrubby or herbaceous plants, with minute flowers and undivided leaves. The few British genera are mostly found in the southern counties of the kingdom; and the plants of this order occur chiefly in Southern Europe or Northern Africa.

1. CORRIGÍOLA (Strapwort).—Sepals 5; petals 5, as long as the calyx; stamens 5; stigmas 3, sessile; fruit 1-seeded, inclosed in the calyx. Name from corrigia, a strap, from the form of the leaves.

2. HERNIÁRIA (Rupture-wort).-Sepals 5; petals 5, resembling barren filaments; stamens 5, inserted on a fleshy ring; stigmas 2, nearly sessile; fruit 1-seeded, inclosed in the calyx. Name from the disease which it was supposed

to cure.

3. ILLECEBRUM (Knot-grass).—Sepals 5, coloured, thickened, and terminating in an awl-shaped point; petals 0, or 5; stigmas 2; fruit 1-seeded, inclosed in the calyx. Name from the Latin illecebra, an attraction.

4. POLYCARPON (All-seed).-Sepals 5; petals 5, notched; stamens 3-5; stigmas 3, nearly sessile; fruit 1-celled, 3-valved, many-seeded. Name from the word polys, many, and carpos, fruit.

1. CORRIGÍOLA (Strapwort).

1. C. littoralis (Sand Strapwort).-Stem spreading, leafy; flowers stalked in small clusters; stem-leaves oblong, narrow below. Plant annual. This rare and pretty little Strapwort spreads itself over the ground, bearing, from August to December, tufts of little white flowers. It grows on Slapham Sands, and near the Star-point, in Devonshire; and is found in great abundance on the banks of the Loe Pool, near Helston, in Cornwall. It is the Corrigiole of the French, the Lingenkraut of the Germans, the Riempjis of the Dutch, and the Corrigiola of the Italians.

2. HERNIÁRIA (Rupture-wort).

1. H. glábra (Smooth Rupture-wort).-Stem prostrate, clothed with minute curved hairs; leaves oval, narrowing towards the base, more or less hairy, in some cases fringed with delicate hairs; flowers sessile, axillary. Plant perennial. This varies very much in some of its characters. In one variety the leaves are quite smooth, and in the other the leaves have sometimes hairs on the surface, with a delicate fringe around the edges, like an eyelash. Some botanists think the latter a permanent distinction, and describe the plant in this condition as a different species, under the name of H. ciliata. The plant is sometimes said to resemble Wild Thyme in its habit, but the flowers are green. They grow from July to September, either in tufts from the axils of the leaves, or the clusters form a crowded spike interspersed with leaves. The plant is not common, occurring in some of the southern counties of England, and in the western parts of Kerry, in Ireland, though nowhere in any abundance, save at the Lizard

Point, Cornwall. A variety of a more hairy nature is by some botanists termed H. hirsuta. Its hairs are spreading, but in other respects it resembles the ordinary form.

3. ILLECEBRUM (Knot-grass).

1. I. verticillátum (Whorled Knot-grass). Leaves broadly egg-shaped, smooth; stipules white, chaffy and jagged at the margin; stems slender. Plant perennial. This little Knot-grass, doubtless, received its English name from its entangling stems. These have a reddish hue, and the small white flowers which grow around them in axillary whorls, are remarkable for their thick calyxes. The plant is found on boggy lands and in standing pools in Cornwall and Devonshire. In the former county it is not uncommon. It flowers from July to September. One of its old names was Whitlow-grass, from a fancied efficacy in its cure of whitlows. The Germans call it Nagelkraut, and the Spaniards Nevadilla. It is the Paronique of the French.

4. POLYCARPON (All-seed).

1. P. tetraphyllum (Four-leaved All-seed).-Stems prostrate and branched; leaves oval, tapering at the base, upper leaves in pairs, lower in fours; flowers with 3 stamens. Plant annual. This plant is neither conspicuous nor frequent in this kingdom, occurring chiefly on the southern coast of England. It has also been found in Glamorganshire, and is a common weed in the Isle of Jersey, growing all about St. Aubyns, on sunny banks, on hedges, and in gardens. It produces, from May to August, numerous little greenish white flowers. It has plenty of tiny seeds in its small two-valved capsules; but the name which it now bears was originally applied to the common Knot-grass (Polygonum aviculare), which it somewhat resembles. One of its old English names was Linum.
