in threes, their stalks shorter than the bracteas, smooth, naked or slightly setigerous, glaucous; tube of the calyx urceolate, naked, glaucous; segments permanent, equal to the petals, 3 of them copiously pinnate, and all of them thickly covered with glands beneath. Petals white, sometimes slightly tinged with pink, obcordate. Styles hairy, columnar, the stigmas collected into a roundish head. The total absence of glands on the leaves distinguishes this from every variety of R. tomentosa.

RUBUS, (p. 108.)

7. R. macrophyllus, stem somewhat angular and furrowed; prickles uniform, few, small; leaves digitate, of 3 or 5 stalked elliptical or ovate leaflets, very large, thin, soft and pliant, green on both sides, hairy; panicle repeatedly divided, somewhat corym、 bose; petals white.-Hook. Brit. Fl. i. 247.

Hab. In deans, in shaded and rather moist situations.
Near Houndwood. July, August.

8. R. saxatilis, stems herbaceous, ascending, slightly prickly, with prostrate runners; leaflets three; panicle with few flowers, small, greenish-white; calyx of the fruit converging, without prickles or glands; fruit red.-Stone Bramble.

Hab. Lees'-Cleugh, a wooded ravine near Langton Lees farm-house, plentiful, Mr Thomas Brown. June, July.

POTENTILLA. (p. 108.)

5. P. argentea, stem ascending; leaflets 5, wedge-shaped, jagged, white and downy beneath; flowers small, yellow, numerous, in a white cottony corymbose panicle.-Hoary Cinquefoil.

Hab. Road-side west of Stitchell, not common, Mr R.
Dundas Thomson. June, July.

NEPETA.

1. N. cataria, whorls stalked, crowded into spikes; flowers very numerous, white, lower lip flesh-coloured, dotted with crimson; leaves finely downy, heart-shaped, stalked, with tooth-like serratures. Common Cat-mint.

Hab. "Near Gateheugh, in the west of Berwickshire,”
Mr W. Baird. July.

"The later herbarists do call it Herba Cattaria, and Herba
Catti, because the cats are very much delighted herewith;
for the smell of it is so pleasant to them, that they rub
themselves upon it, and wallow or tumble in it, and also
feed on the branches and leaves very greedily."-GERARDE.
On this account it can only be preserved in gardens by
sowing the seed, for, by the handling in the process of
transplanting, or in the languid state subsequent to it, the
peculiar scent is exhaled, and the cats are attracted to the
plant, which otherwise they are unable to discover.
" If
you set it, the cats will eat it; if you sow it, the cats will
not know it."

MENTHA, (p. 126.)

1. M. viridis, spikes interrupted: leaves sessile, lanceolate, acute, naked; bracteas bristle-shaped, somewhat hairy, as well as the teeth of the calyx; flower-stalks very smooth.-Spearmint.

Hab. At the sides of the Whiteadder above Gainslaw-ford,

on the north side, in two or three large patches, and apparently perfectly wild. Aug. Sept.

MELAMPYRUM, (p. 128.)

2. M. sylvaticum, leaves in distant pairs, entire; flowers axillary, turned to one side; corolla deep yellow, small, gaping, the lip deflexed; height about 1 foot.-Wood Cow-wheat.

Hab. Banks of the Dye above Longformacus, Mr Thomas
Brown. July, Aug.

My specimens from Mr BROWN agree entirely with the de-
scriptions of authors, and also with authentic specimens of
M. sylvaticum, with which they have been compared. I
mention this the more particularly, because I am tolerably
certain that, in the above station, it grows intermixed with
the more common M. pratense. The latter, in addition to
its other habitats, I may add, grows very abundantly in
the woods between Houndwood and the Pease-bridge, and
on some wooded parts of the banks of the Whiteadder be-
tween the Retreat and Elmford; but in no part of Ber-
wickshire have I observed it to attain the size of the plant
figured in Eng. Botany, and which I have gathered in the

woods at Roslin. Our plant is rarely above 6 inches, bushy, with narrow linear leaves, and very often with entire bracteas. My Mel. montanum (vol. i. p. 136.), I am now satisfied, is only an alpine state of this. It may be found in profusion on Hedgehope, one of the Cheviots, and on Hepburn-hill at Chillingham, but in the latter station the plant begins to assume the appearance of the true pratense.

LATHREA.

1. L. squamaria, flowering branches erect, simple; flowers axillary, unilateral, subpendulous; lower lip in 3 lobes. (tab. viii.)

Hab. Damp shaded woods, rare. In some natural wood above the Retreat plentiful. April.

Roots fibrous. Stem subterraneous, irregularly branched; branches often clustered, short, obtusely pointed, covered with fleshy imbricated leaves, which in shape resemble a horse's-hoof in miniature. Flower-stalk or branch thick, succulent, 4-6 inches high, tapered upwards, purplish, downy, bearing a spike of crowded flowers of a pale purplish-pink colour, arranged in 4 rows, and all leaning to one side. Bracteas large, inversely heart-shaped, entire, cream-coloured, smooth, thin. Stalk of the lower flowers as long as the bractea; of the upper shorter, compressed, clothed with a soft glandulous down. Calyx cream-coloured, downy, cleft into 4 subequal segments. Upper lip of the corolla entire or merely emarginate, sprinkled over with a short glandulous down; lower lip 3-cleft. Fila ments purplish-pink, smooth, with downy anthers. Style protruding, filiform, smooth, tubular, with a dilated stigma. Germen smooth. Gland semilunar, with an obtuse tooth, secreting at the base a sweetish fluid. Supposed to be parasitical, attaching itself to the roots of trees, but I could not trace the connection, perhaps from my time not permitting me to dig it up with sufficient care.

I have been particular in the description of this singular plant, for there are some particulars in which it differs from the plant of the English Flora. 1. The upper lip is not cloven; it is said in SMITH's description to be" deeply cloven." 2. The leaves are not ovate, as SMITH says they are. 3. The segments of the calyx are not smooth, for the whole calyx is covered with down. 4. The style projects considerably beyond the under lip, while in Eng. Fl. it is "scarcely the length of the corolla." 5. The nectary is not notched, for the centre rather projects.
