oval, terminated by an awn, scored with red veins, slightly woolly. Head single, usually roundish, situate between a pair of nearly sessile leaves, and in part surrounded by their stipulæ, smaller, and of a deeper purple than those of T. medium. Calyx short, slightly woolly, generally scored with red veins; teeth bristle-shaped, woolly, usually tinged with purple. Blossom reddish purple, sometimes white; of one petal; tube long; standard longer than the wings and keel, blunt, notched at the end ; wings blunt. St. Stems always bowed upwards at the base.

P. B. May-Sept. Var. 2. Smaller. Leaves inversely heart-shaped, the upper generally opposite. Spike bare. Ray.

Ray 13. 1. English Botanists have considered this as a smaller var. of T. pratense, the

stipulæ being awned and the teeth of the calyx nearly equal, as in that species; but it differs in other respects very materially, the leaves being opposite, the leafits small, short, inversely heart-shaped, the fruit-stalk

very long and destitute of floral-leaves. Afzel. Linn. I'r. i. 227. Between Peckham and Camberwell. Hudson. Var. 3. Cultivated. Larger and more upright than var. 1. Leaves some

what paler and thinner. Flowers somewhat paler. Does not propagate itself by seed, or continue so long in the ground. Ray.

Fl. Dan. 989. Stems strong, almost smooth, furrowed, twice as tall as those of var. 1.

Heads large, oval, hairy. Petals more expanding, and styles shorter than those of var. 1. Mill.

The heads are used in Sweden to dye woollen green. With alum they gire a light, with copperas a dark green. (This is one of the oldest and most useful plants in cultiva-' tion, yielding an abundant and putritive crop; but it soon exhausts the ground. Mr. Salisbury remarks that the seeds of Clover have the property of remaining long in the ground after it has appeared to be exhausted, when ashes laid on will by their stimulating effects, cause the sceds to vegetate. Hence some persons have affirmed that (soap) ashes, when scattered orer land, will produce Clorer, (vid. 7'. repens.) Though

Nature should provide Green grass and fatt’ning Clover for their food," Cattle should be turned into heavy crops of Clover at first rery cautiously, or it may soon prove fatal, especially if wet with dew or rain. When intended for immediate use, it should be mown in the middle of the day. Clover seeds of all kinds are necessary ingredients in laying down pasture lands. - Bees extract much boney from the sweet scented blossoms. The young plants are often injured by the same little jumping beetles, Hallion, that attack turnips. See Obs. on the Clover Weeril in Linn. Tr. sol. vi. A small weevil, also spion Anvisemoratum, fceds upon the seed of Purple Clover, and in most seasons does the crop considerable damage. But this mischief is njoderated by the penetrating Ichneumon, froni whose research the insect, concealed eren within the legume of the plant, is not secure. Indeed, so wisely and mercifully is the balance adjusted throughout the whole economy of nature, that, though the impending evil be calculated to excite serious apprehension, we may rest assured that He who rides on the tempest and directs the storn, also works by means imperceptibly minute for the general welfare of created being.

Broad-leaved Clover. Meadows and pastures.*
Var. 4. Flowers cream-coloured : in other respects exactly resembling

T. pratense.
A single specimen, found by the Rer. Mr. Swayne, in a field belonging to

Tracy Park, near Bath. (Two solitary plants observed in a field of pur

ple, near Uxbridge, by Mr. W. Christy. E.) This plant has not the general hairiness, the long horns of the stipulæ, or the

very long tooth of the calyx, so striking in T. ochroleucum. (Var. 5. T. pratense perenne. Perennial Red Clover of Sinclair.

Hort. Gram. Root slightly creeping, extremely fibrous. Of a darker green than the com

Flower-stalks longer and more slender, with a disposition to grow flexuose. Heads of flowers less crowded, though equally large. When young the flower-head is ex

tremely pubescent. In the fertile grazing lands between Wainfleet and Skegness, in Lincoln

These circumstances, together with the great length of the lower tooth of the calyx, sufficiently distinguish it from the yellow-flowered var. of T. pratense.

pairs, obtusely oval-spear-shaped. Leaf-stalks short. Leafits heartwedge or egg-shaped, very entire towards the base, serrated upwards, the odd one on a short leaf-stalk, the side one nearly sessile, smooth. Fruit-stalks from the bosom of the leaves, longer than the leaf-stalks, slightly dowuy. Pedictes very short. Floral-leaves none. Flowers after flowering bent back, hanging loosely and separate. Woodw. Stem a little hairy. Leafits inversely heart-shaped, mid-rib a little hairy underneath, with about seven semi-transparent lateral ribs. Flowers yellow; loosely tiled. This is the most common sort of Hop Trefoil, and may be found in almost every dry, sandy, or gravelly pasture, especially where the turf is fine, but varying greatly in size according to the richness or poverty of the soil, and flowering from May to August. On considering that the above described plants frequently grow intermixed, are very similar in general habit, and subject to considerable variation in size, we hesitate to admit the latter as a distinct species. On this point the acute Greville observes, “ I cannot find sufficient difference between T. filiforme and minus, to make them even varieties. The middle leafit is both sessile and petiolate on the same specimen in both plants, and is so represented in E. Bot. 1257 as T. filiforme. The teeth of the calyx, said by Sir J. E. Smith to be glabrous in the same plant, are figured in E. Bot. slightly hairy in both. The peduncles are pubescent in each; as to the latter being somewhat flexuose or straight, and the heads few or manyflowered, no importance can surely be placed on such characters.” Fl.

Leuves ternate, inversely egg-shaped, smooth, somewhat toothed. Linn. Every part of the plant, except the leaves, is buried in the sand, (so that even its seeds are actually perfected subterraneously, and without light: E.) but on putting down a knife or a stick the whole plant may be raised, and then its flowers and fruit come into view. The clusters in some of

the older plants are as large as a small nut. Woodw. (SUFFOCATED Trefoil. Welsh : Meillionen fygiedig. E.) Discovered in
