certainly very rare in the Isle of Wight, where I have found it but once on an eastern fence with C. danica on High Down Freshwater, directly above and at the back of Watcomb Cave, but in no great quantity. The var. B. grænlandica, Sm., I have on the authority of my friend the Rev. G. E. Smith, as growing on the edge of Freshwater Down, but not having yet fallen in with this alpine form myself, I am inclined to believe it was inadvertently named in place of the commoner state of C. officinalis, and that his station and mine are identical.

Cochlearia danica, add, Plentiful on the South Beach, Hayling

Island.

anglica. Muddy places near the sea in the county and island, but rare, at least in the latter. Shores of Brading Harbour, Yarmouth; Mr. Snooke. Betwixt Southton and Netley.

Camelina sativa. See Alyssum calycinum, p. 209. Of this I have seen no specimen, and from the circumstance mentioned under the head now quoted, of its being mostly if not always in this country the associate of flax, I am in doubt as to the accuracy of the fact of its occurrence near Alverstoke. N. B.-Lepidium sativum occurs here and there partially naturalized in this island on banks, waste ground, and by road-sides at Sandown, Ventnor and elsewhere, but is very fugitive in all its casual stations.

Crambe maritima.

In various places along the south shore of Hayling Island, very sporadical, though truly indigenous. A single specimen found by me some years back, on the sandy beach at Norton Freshwater, western coast; Dr. Pulteney in Hamp. Rep.

Cakile maritima. Sandy shores of the county and island; extremely common, Sandown Bay. Abundant near the south-west corner of Hayling Island.

Raphanus Raphanistrum. Not uncommon, and sometimes abundant in cultivated fields in the Isle of Wight, and I presume throughout the county. Flowers sometimes white, and with the veining of the petals very faint and inconspicuous.

Frankenia lævis, add,

Island, Emsworth, &c.

Drosera longifolia, add,

Very common in mud flats on Hayling

Short Heath Oakhanger, near Selborne. anglica. Ramsdown, near Heron Court, Christchurch, Mr. Curtis (in litt.), Icon ad exemplar ex loco in Brit. Entom. x. t. 473. Mr. C.'s exquisite figure represents the true anglica, which I have not seen from this county, and inserted solely on the authority

of Pulteney, which is thus corroborated for a plant of decided rarity in the south of England.

Parnassia palustris, add, In various parts of the (New) Forest; Mr. J. S. Mill in Phytol. i. p. 92.

Dianthus prolifer, add, In considerable plenty on the south beach, Hayling Island, along the way to the Passage House, October 3rd, 1848, and still in flower. Cumberland Fort, Portsea Island;

Dr. Macreight, Man. Brit. Bot.

Armeria, add, Wicor Hard; Mr. W. L. Notcutt.

Silene maritima, add, Abundant on Hayling Island. A variety with the margin of the leaves cartilaginously spinulose occurs occasionally in the Isle of Wight.

Lychnis Flos-cuculi. Very frequent in wet places.

Githago. Very common, and often far too abundant amongst corn and other crops.

Spergula nodosa, add, Sandy ground in the New Forest; Mr. T. B. Flower!

Sagina procumbens. Common everywhere, on and under walls in dry pastures, &c.

maritima. Rare?

Helen's, Isle of Wight.

Sandy shore, Gurnet Bay, and at St. At West Cowes, near the Yacht Club House; Dr. Martin !! Probably not uncommon on the Hampshire

coast.

apetala. Corn-fields and dry pastures frequent, at least in

the island. Abundant near Ryde.

Profusely on

Alsine rubra. Common on dry sandy ground. rocky ledges behind Bonchurch, with Crithmum maritimum, and on the chalk cliffs at Freshwater Gate, Isle of Wight. The plants in these maritime situations preserve their character as regards the shape and roughness of the seeds, length of the capsules, and aristate leaves, but the latter are semi-cylindrical beneath, or nearly so, the plant very much branched, forming dense tufts, the roots thick (perennial?) and as well as the base of the stems, subligneous. This form accords with the description of Arenaria macrorhiza, Req. in Bartoloni's Flora Ital. iv. p. 687. A. rubra, y. macrorhiza, Moris, Fl. Sard. i. p. 278. A. media, B. macrorhiza, D. C., in Duby Syn. ii. p. 1025, and which Moris judiciously considers a mere variety, assigning very sufficient reasons for his opinion.

marina. Salt-mashes and waste ground by the sea, common. A good species?

Stellaria uliginosa. Frequent in wet and boggy ground.

Stellaria graminea. Abundant over the B. intermedia, Gaud. Fl. Helv. iii. p. 185. the calyx; leaves more or less glaucous. Wight.

county and island. Var. Petals much longer than Near Westridge, Isle of

holostea. Profusely bedecks our hedgerows with its pure, starry blossoms in spring and early summer. Var. B. laciniata. Petals scarcely equalling the calyx in length, deeply divided almost to the base into three segments, of which the middle one is linearlanceolate, the two exterior with a tooth on the inner side. Quarr Copse, Binstead, Isle of Wight, May, 1838. Of this singular variety I found a good many specimens, and at first imagined the laciniated appearance of the petals to have resulted from mutilation by insects, till the regularity of the monstrosity in all, which I traced in the bud, proved to be the work of Nature. In this state the flowers bore some resemblance to those of S. uliginosa. A form very similar, if not the same, is recorded in the 'Phytologist' (Phytol. i. 264) for July, 1842, as found near Pont-y-Pool, by Mr. J. Bladon. Cerastium glomeratum and C. triviale. Very common in pastures, by road-sides, and in waste places over the county and island. semidecandrum. On waste, sandy ground, wall-tops, &c., very common in spring and early summer in the Isle of Wight, as on Ryde Dover, &c. A most variable and perplexing plant, on the different forms of which botanists have wasted much time and ingenuity in endeavouring to find permanent marks of distinction where none exist. We need but compare the descriptions and figures of those who have laboured the most to elucidate our common Cerastia, to be convinced that not one has seized upon any absolutely fixed mark of distinction betwixt C. triviale, semidecandrum, tetrandrum and pumilum, the very multiplicity of their synonyms, and the elaborate commentary of Fries (Nov. Fl. Suec.), who has still further augmented the difficulty attending their study by increasing the species and changing and mixing the names first imposed, prove how little writers have advanced in assigning to each its precise limits. Mr. H. C. Watson's pleasant but somewhat caustic remarks in Cybele Britannica' on the above species, with two others of more recent creation, are exactly in accordance with my own views of their validity, which have not been hastily assumed, as a few years since I devoted much time and pains to the study of the British species and varieties of this genus inhabiting the south of England. The result of my inquiry, embodied in notes and descriptions too multitudinous for insertion here, even in a condensed form, was only increased perplexity,

and of course augmented scepticism and distrust of the labours of others. Still I am willing to give brevet rank to the five veteran Cerastiums specially introduced into these Notes, and to call them species by courtesy, without joining the opprobrious epithet of "book" to them, trusting to time either to confirm their claim to the honour, or to revoke the grace which bestowed it. Yet I shall protest against granting a like degree to any more of the scions or offsets from stocks of such dubious character and deserving, and rejoicing that one of these younger branches has quietly disappeared by a process of self-absorption, devoutly hope that another and only remaining one, still dark green and flourishing where the departed so lately bloomed in new-born dignity, will make its exit from the court of Flora in the same easy and agreeable manner without compulsion, as being too nearly allied, like most, I fear, of the others we are treating of, to that confessedly little-renowned and retiring individual, C. obscurum of Chaub., to the paternity of which personage, whoever he may be, it seems under no great obligations for its name or reputation in the vegetable world.

Cerastium tetrandrum. On dry pastures, banks, wall-tops and sandy heaths, frequent in the Isle of Wight, and perhaps in the county generally. On Ryde Dover. I believe my plant to be exactly that of Curtis, on a renewed examination of my specimens so named in

1838.

pumilum. Curt. ? Sandy places rare. Abundant on the sandy fence of the Ferry Boat Inn, opposite Bembridge, Isle of Wight, April, 1842. I cannot now quite answer for the exact correspondence of my plant with the C. pumilum of Curtis, as I at that time considered it, what I still think it likely to be, a mere variety of C. semidecandrum, but my notes express no doubts of their identity, and I was extremely cautious about coming to conclusions until after repeated careful comparison of the living plants with the best and most authentic descriptions and figures. At that date I was not so much in the habit of preserving specimens of what I looked upon as trivial varieties as I have since been, and therefore I cannot now renew the comparson of my own with Curtis's pumilum, but having quoted his figure in Flora Londinensis' without a ? after it in my MS. notes, which it was my constant rule to do where the least doubt remained on my mind, I fell pretty well assured of their agreement. It may assist the advocates for retaining this and the remaining forms under their distinctive names, in coming to a conclusion on the subject of our Isle of Wight C. pumilum, to add what I considered, VOL. III. 2 Y

though not without some uncertainty, as a synonym and figures of the island plant. C. glutinosum, Fries, Nov. Fl. Suec. ed. alt. p. 132 ? Reichenb. Iconogr. Bot. ii. t. 181, fig. 315, 316? (C. semidecandrum of that author). In my Ryde specimen of C. tetrandrum the membranaceous margins of the sepals vary extremely in breadth, even on the same plant, they are mostly broader on the alternate segments, at one time very wide, at another nearly or quite obsolete. Flowers by far most frequently four-cleft, with four stamens and as many styles, sometimes five-cleft, with five stamens, and four-cleft on the same plant; whilst not unfrequently I find four-cleft flowers with five stamens and only four styles. Certainly the bracts are not scarious in any of my specimens of C. tetrandrum, as Mr. J. Woods has well remarked in his tour in Brittany,* which I presume Mr. Babington means to express by the term "herbaceous." My own impression after much careful investigation is, that C. tetrandrum is a dwarf maritime state of C. semidecandrum, which last may itself, as Mr. W. Wilson suggests, prove to be a modification of C. viscosum (C. triviale), as it is difficult to assign a character to the one which is not occasionally assumed by the other. An extremely humble plant of this genus, not an inch high, with four- (rarely five-) cleft flowers, spreading in the form of a cross, grows profusely on our downs and short pastures, which are quite enamelled with it in the spring, and this I have been in the habit of calling, I know not with what propriety, C. tetrandrum, though probably quite as near to any of the others we have been speaking of.

Malva moschata, add, Common at Appleshaw. at Selborne.

Not unfrequent

Hypericum hirsutum. Extremely uu d ant in woods and thickets in various parts of the Isle of Wight and mainland, especially on the chalk.

elodes, add, Profusely in the boggy parts of Short Heath, at Oakhanger, near Selborne.

Geranium pratense, add, Plentifully along the banks of the brook and in damp meadows adjacent betwixt the Priory Farm and Oakhanger, near Selborne, following the winding of the stream for nearly half a mile, and still partially in bloom, September 17th, 1848. Observed in a few other places about Selborne.

Radiola millegrana, add, On Short Heath, near Selborne. Wolmer Forest. In cart-ruts on Parley Heath; Mr. Curtis.
