INTRODUCTION. THE study of the British Grasses is one of no mean interest, inasmuch as many of the species are very graceful and beautiful, whilst a number have added to this interest, usefulness in an agricultural point of view. Great Britain possesses about one hundred and forty species, and many very distinct varieties. Beautiful as many of them are, still they sink into insignificance in comparison with some of the Exotic species. The huge Pampas Grass, (Gynerium argenteum,J with its large graceful foliage, and flower stems ten feet in length; the Quaking Grass, (Briza maxima,} of southern Europe, and many others, are all handsome hardy herbaceous plants. Amongst the British Grasses six species flower in April, three in May, forty-four in June, sixty-six in July, and nine in August. In writing the present work the author has consulted Dr. ParnelPs "British Grasses," Hooker and Arnott's "British Flora," Smith and Sowerby's "British Botany," Smith's "English Flora," and several other works. Dr. ParnelPs "British Grasses" is an admirable work, containing a vast amount of research and microscopic investigation; such a book is exceedingly valuable, and must necessarily be expensive; it is therefore the object of the author in the present book, to furnish a brief description of each species, with a coloured illustration; and the aim will be to complete the work in about twenty shilling numbers, so as to place it within the reach of those who cannot afford to purchase expensive works. INTRODUCTION. The study of our native flora renders a visit to any and every different locality interesting, inasmuch as we come upon fresh objects of attraction wherever we happen to bend our steps. How often have we heard it declared that such and such a place was dull, nothing going on, nothing to do in order to pass away time pleasantly; whilst a naturalist would tell you that those identical localities teemed with objects of interest. To those who extend their pleasures to the beauties of this earth, there are attractions everywhere. We are so accustomed to Grasses varying from one to four or five feet in height, that when we turn our attention to Exotic species above ten times these dimensions, we become bewildered, yet so it is. In the New Continent Baron Humboldt discovered a gigantic Guaduas which grew from fifty to sixty feet high. To the east of the Duida Mountains, growing at the foot of the great mountain cluster of Maravaca, is a colossal grass with stalks whose joints measure above eighteen feet from knot to knot, and which the Indians make use of as blowpipes for the discharge of their arrows. This noble grass, which is a species of Arundinaria, is well described by Schomburgk; he speaks of it as growing in large tufts like the Bambusa, the first joint rising in the old cane sixteen or seventeen feet before it com- mences to bear leaves. Although it attains the height of forty feet, it scarcely exceeds half an inch in diameter. The top is always inclining, which enables it to withstand winds more easily. This grass appears to be confined to the sandstone mountains between the Ventuari, the Paramu, (Padamo,) and the Mavaca. Thus in tropical regions grasses exceed the height of our noble oaks. In Italy we have the first approach to a tree-grass in the species Arundo donax; north of this there are no arbo- rescent species. The most Antarctic flowering plant is a grass, (the Aira An- tarctica;) it is found in south latitude 62° in South Shetland INTRODUCTION. Ill Islands, at an elevation of seven thousand and forty-six feet above the level of the sea. Trisetum subspicatum is a plant having an extraordinary geographic range ; Dr. Hooker mentions it as being found over the Peruvian Andes and Rocky Mountains, extending into the Arctic regions to Melville Islands, (the winter quarters of Capt. Sir Edward Parry in one of his Arctic expeditions.) Found also in Iceland, Greenland, Kamtschatka, and on the Alps; then again met with on Campbell's Island, which is south of New Zealand, thus extending over 127° of latitude — from 54° south latitude to 72° 50' north. Amongst useful and ornamental grasses may be mentioned the Bamboo. Then again an aromatic grass oil is extracted from the seed of the Andropogon schwnanthus , or Calamus aromaticus, and the Lemon grass oil from another species of the same genus : these are Indian grasses. This latter species gives out an odour very similar to that of the Lemon-scented Verbena, ( Aloysia citriodora,J a plant introduced seventy years ago from Chili, and now to be met with in almost every garden. It must not be forgotten that the bread we eat is derived from a grass, ( Triticum vulgare,} and the beer we drink from another grass, ( Hordeum distichum.J We feed our horses with oats, (Avena sativa,} our cattle with rye, (Secale cereale,J sweet-scented vernal grass, ( Anthoxanthum odoratum,) and many others. The corn of India, commonly known as maize, is the Zea mais, a tropical grass, which was introduced into England as early as 1562; and the Curagua, (Zea Curagua,} another species inhabiting Chili, brought over to this country in 1824. Again, our sugar is a grass, derived from the sugar-cane of India, (Saccharum officinarum,) our rice, (Oryza sativa,) another, and millet a third. Then the Guadua angustifolia, (Bambusa Guadua,J generates in its interior large quantities of the sili- ceous Tabaschia, (cow-milk,) much esteemed by the natives as a pleasant beverage. IV INTRODUCTION. The Bamboo comprise a small tribe of huge Exotic Grasses of the East Indies, found in the Islands of Java and Mada- gascar. There are eight species found at Apetal; — the B. aristata, growing twenty feet high; B. arundinacea, forty feet; B. glauca, twenty feet; B. nigra, twenty feet'; B. pubescens, B. spinosa, B. stricta, and B. verticittata, all attaining a height of twenty feet. The Tussac Grass, (Dactylis ccespitosaj of the Falkland Islands and Terra del Fuego, was brought to this country by the celebrated arctic and antarctic explorer, Sir J. C. Ross. It is a most valuable grass for agricultural purposes, being large and standing the climate of England. The young shoots are boiled and eaten like asparagus. It is also an extremely orna- mental plant. All the grasses, including wheat, barley, oats, and rye, yield starch unmixed with any deleterious matter. One English grass, the Bearded Rye Grass, (Lolium temu- lentum,) is said to have poisonous qualities, and this I believe is the only poisonous grass. Every British Grass but one is contained in the third class of Linna3us — Triandria; the solitary exception is Anthoxantlium odoratum, belonging to the second class — Diandria. The Grasses are in many respects allied to the sedges, the latter are distinguished, however, by their solid stems, (the Grasses are all hollow stemmed,) and by their leaves completely surrounding the stem, like a tube; in the Grasses they only sheathe instead of surrounding the stem. All the species have a thin siliceous coating on their stems, which appears to impart greater strength and durability than could have been procured by simple ligneous fibre, and this gives their stems that highly-polished appearance. Flint is also formed at their joints. It is one of the wonders of the vege- table kingdom, how solid flint can be formed on the stems and in the interior of the stalks of grass; and when we observe INTRODUCTION. V the minute rooty fibres through which it must ascend, it is at once apparent that a power to dissolve flint is given to the Grasses, and that it is conveyed upwards in a liquid or fluid state. To the Grasses we are in a great measure indebted for the splendid green of the landscape, and indeed every one must look with pleasure on the vivid freshness of the fields in early spring, when the increasing warmth has induced them to put forth fresh leaves. Although the farmer reaps a plentiful harvest from the choicest of our British graminaB, there is one species that may be said to be his greatest pest. I allude to Twitch, or Couch Grass; rapid in its growth, tenacious of life, and propagated with a freedom scarcely to be met with in any other plant; a field soon becomes covered with this troublesome weed, its under- ground creeping stems spreading in all directions, until, if left alone, it would speedily take sole possession of the land, to the exclusion of all other crops. Some time since it was proposed to try experiments in order to ascertain whether this abundant plant might not be turned to some useful purpose, and the manufacture of paper from it was proposed. It would be a great boon to the farmer if something could be done with this plant, something that would enable him to clear the soil with profit to himself beyond that of clearing his land. It is very surprising that so little appears to be known amongst botanists and farmers regarding our British Grasses, in very many instances, beyond the knowledge that such and such is a Grass, nothing more is known; indeed to those who spend their whole lives amongst this tribe of plants, if they are told how many British species are to be found in their fields, hedge- rows, and plantations, they are astonished, and will scarcely believe the information. Yet a knowledge of the agricultural Grasses, at all events, would be of inestimable benefit to the farmer. There are profitable Grasses, and those that are un- vi INTRODUCTION. profitable; there are Grasses which yield an early crop, and there are others that are much later in their growth. Again, some species nourish best on a strong clayey soil, others where it is dry and gravelly, and others in damp situations. Grasses are to be found everywhere, by the sea-side, in brackish water, on mountain tops, in woods, swamps, sandy plains, in short whichever way we turn Grasses are to be seen. For works treating on the British Grasses, we are indebted to Sir James Edward Smith, who has, in his "English Flora," devoted many pages to this subject; to Sir William Jackson Hooker, and Dr. Arnott, who have also devoted much space to the Grasses, in their "British Flora;" to Mr. Sowerby, who, in his "English Botany," has a whole volume on the Grasses. Other works published on this subject are "Gramina Britan- nica," by J. L. Knapp, published in 1804; Withering's "British Plants," published in 1796; Hudson's "Flora Anglica," published in 1778; Curtis's "British Grasses," published in 1790; Schreber's "Beschreibung der Graser," published in 1769; De Candolle's "Flora Fran9ois," published in 1805-15; Deering's "Catalogue of Plants round Nottingham;" the works of Ehrhart, published about 1790; Grave's "Monograph on the British Grasses," published in 1822; Jussieu's works; Leer's "Flora Herbornensis;" Linnaeus, various works; Martyn's "Flora Rustica, 1791;" Peti- ver's "Graminum," etc., published in 1717; Schrader's works; Sinclair's "Hortus Gramineus Woburnensis," published in 1816; Willdenow's works; Gouan's "Hortus Regius Monspeliensis," published in 1762; Oeder's "Flora Danica," published in 1766; Plukenet's various works; Morison's "Historia Plantarum Uni- versalis," published in 1680; Scheuchzer's works; Haller's "Historia Stirpium Indigenarum Helvetia;," published in 1768; Hoffmann's "Deutschlands Flora;" Sibthorp's "Flora Oxoniensis," published in 1794; Roth's "Tantamen Flora Germanics," pub- lished in 1778; Lightfoot's "Flora Scotica;" Gerarde's "Herball," INTRODUCTION. Vll published in 1636; Eelhan's "Flora Cantabrigiensis," published in 180&; Ray's "Synopsis Methodica Stirpium Britannicarum," published in 1724; and a host of other botanists. It is purposed as an "addenda" to the "Natural History of British Grasses/' to describe those Exotic species that are remarkable, either as ornamental plants, useful as introduced species for the agricultural community, or for their domestic interest. In conclusion, I take this opportunity of soliciting of those whose pursuits and inclinations lead them to a study of the Grasses, their aid in specimens and information; for let it be borne in mind, that every one has power to render valuable aid, and in a work like the present, the more assistance that is given, the better able will the author be to produce a work worthy of that patronage which, from its cheapness, must have a wide circulation. BRITISH GRASSES. GRAMINEJB. JUSSIEU. FLORETS mostly perfect, yet occasionally imperfect, or even without stamens or pistil. One, two, or more imbricated on a common axis or rachis situated within an involucre, called a calyx by Linnaeus, consisting of one or two (rarely none) valves or glumes, the whole constituting a spikelet. Perianth, (called corolla by Linnaeus,) glumaceous, the fertile florets generally consisting of two dissimilar glumellas or valvelets. The exterior or lower one simple, mostly keeled or having a midrib, the interior or upper one having two lateral or dorsal nerves; occasionally one or even both are wanting. Stamens hypogynous, usually three, but either one, two, three, four, five, six, seldom indefinite. Anthers, bi-celled, attached by their back near the middle, versatile. Ovary superior, single-celled with one ovule, having mostly two (more rarely one, or even none) diminutive hypogynous scales, called lodicules or abortive stamens. Styles usually two, which are simple or bifid, more rarely one or three. Stigmas mostly plumose. Pericarp closely incorporated with the seed. Embrio lenticular, external, situated at the base of the farina- ceous albumen. The culms or stems generally fistulose, mostly simple, herba- C 2 GRAMINEJE. ceous, and knotted. Occasionally branched, seldom shrubby. Hollow mostly, being closed at the joints. Leaves, a single one to each node, having a sheath slit lon- gitudinally on one side, and frequently possessing a membranous appendage at the summit, called a ligule. The flowers, which are small, are solitary or in spikelets, which are panicled or spiked. • IIO X A NT-HUM.. ODCKATUM. I ANTHOXANTHUM ODORATUM. PAENELL. YAHL. MAETYN. STILLINGFLEET. KOCH. SMITH.

THE pleasant odour that is so very powerful in our hay-fields, whilst the grass is drying, owes much of its scent to the present species, a scent very similar to that of the Woodruff, ( ' Asperula odorata.J It springs up early, and is a true permanent pasture grass, and is to be met with almost everywhere both on strong and light soils. A common species throughout Europe, and in the more northerly parts of North America. Panicle upright, form ovate-oblong, with short hairy branches, length an inch and a half. Spikelets in form ovate-lanceolate, large, erect, four or five together, one awned floret. Calyx two remarkably unequal glumes, which are hairy; the larger glume is three-ribbed, the outer smaller glume destitute of lateral ribs. Floret consisting of two palese, oblong in shape, hairy, brownish, the palese equal in size, being half the length of the larger glume, and having two awns very dissimilar in length.

There is a rush-like character in its leaves, which are rigid, harsh, and forming thick tufts which continue all winter. It is of no use for agricultural purposes, cattle rejecting it if they can find other food. Common throughout Scotland, England, Ireland, Lapland, Norway, Sweden, and Germany; also found in the most nor- therly portions of North America. Spike single; spikelets single-flowered, lanceolate in form, de- posited in two rows on one side of the rachis only; the opposite side of rachis naked. Without a calyx. Glumes none. Florets consisting of two palese, the exterior one tipped with a brief rough awn; the inner palea shorter, entire, membranous, and linear-lanceolate in form. Anthers oblong.

Two almost equal glumes, their base mostly connate; membranaceous, and of the same length as the floret. A solitary glumella, having a dorsal awn above the base. ONE of the most valuable agricultural Grasses; cattle are exceedingly fond of it, and being good in quality, and an early species. It flourishes best in meadows which have been drained, on a rich clayey soil. Exceedingly common in Great Britain, and is found also in Russia, Sweden, Norway, Denmark, Lapland, Holland, France, Germany, Italy, and America. In the latter country it is how- ever supposed to have been introduced. Panicle upright, varying from an inch to two inches long, nearly cylindrical in form, having small branches arranged all round the rachis. Spikelets ovate in form, erect, imbricated, numerous. Calyx consisting of two equal-length glumes, acute and jointed at the base, pale green lateral ribs and keels, which are fringed. Floret consisting of a solitary ovate-oblong palea, 8 ALOPECURUS PRATENSIS. with two green ribs on either side; having a lengthened slender dorsal awn arising almost immediately above the base. Upper portion of the keel hairy. Anthers conspicuous, yellow in colour. Styles joined together. Stigmas divided, slender, and downy. Seed ovate. Stem erect, circular, polished, and striated, carrying four or five leaves, with smooth inflated sheaths. Joints smooth. Leaves flat, acute, both surfaces usually rough. Inflorescence compound, branched. Panicle upright, from one to two inches long; cylindrical-oblong, compact, with short branches placed all round the rachis. Length varying from one to three feet, according to circumstances. Root perennial and fibrous. Flowers through April, May, and June, and ripens its seed in July and August. Dr. Parnell gives the following distinctions in his "Grasses of Scotland," from other species in the same genus: — "1st. — From A. geniculatus in upper leaf being only half the length of its sheath; awn extending more than half its length beyond the palea; palea conical, with four distinct broad green ribs; glumes more acute, and of a different shape, whereas in A. geniculatus the upper leaf is nearly the same length as its shield; palea obtuse, with four indistinct green ribs, tinged at apex with purple. 2nd. — From A.fulvus in the awn of A.fulvus not extending beyond the palea. 3rd. — From A. agrestis in the stems and sheaths being smooth, in A. agrestis they are rough. 4th. — From A. alpinus in the panicle being longer; in A. alpinus it is not an inch long; also differs in the position of the awn." My thanks are due to Dr. Wilson, of Nottingham, and to Mr. Joseph Sidebotham, of Manchester, for the illustrated specimens. ALOPECURUS ALPINUS. SMITH. HOOKER AND AENOTT. DON. KNAPP. PAENELL. LINDLEY. PLATE III. B. Alopecurus ovatus, KNAPP. The Alpine Fox-tail Grass. A lopecurus — Fox- tail. A Ipinus — Alpine. A HA.RE northern Grass, growing in marshy situations on mountains at an elevation of three thousand eight hundred feet above the sea. Sheep will feed upon the lower leaves, rejecting the stem of this Grass. It does not appear to be found below the elevation of two thousand five hundred feet. From the circumstance that Alopecurus alpinus will not grow except on high mountains, it is useless as an agricultural Grass. In Great Britain it is peculiar to the Highlands of Scotland, about Loch-na-Gar, Clova mountains, Canlochen, Glen Prosen, Ben Lawers, and Loch Lee. Found also in Greenland, Spitz- bergen, and in the north of British America. Panicle upright, not an inch long, oblong, soft and silky. Spikelets upright, oval, placed all round the rachis, of one-awned floret of the same length as the calyx. Calyx consisting of two acute hairy glumes of the same size, three-ribbed. Floret con- sisting of one palea, with two ribs on either side, and sometimes furnished with a slender dorsal awn. Filaments three and slender. Anthers protruding, and notched at the extremities. Styles united and short. Stigmas two, lengthy, and feathery. Seeds ovate. Stem upright, smooth, circular, bent at the base. Stem D 10 ALOPECURUS ALPINUS. carrying four leaves, whose sheaths are smooth and striated, the uppermost sheath extending beyond its leaf. Joints smooth. Leaves flat and broad, the inner surface and margin rough. Inflorescence panicled. Length from nine inches to a foot. Root perennial, creeping, having lengthened fibres. Flowers in July, and ripens seed at the end of August. The illustration was forwarded by Mr. Joseph Sidebotham, of Manchester, having been gathered on the Clova mountains. ^LOPECURUS A G R E R T I S . IV 11 ALOPECURUS AGRESTIS. LlNN,EUS. WlLLDENOW.

Agrestis — A field. A USELESS agricultural Grass, indeed cattle refuse to feed upon it; when once it takes possession of a field it is difficult to eradicate, and causes much trouble to farmers when growing amongst wheat. It is perhaps better known under the name of "Black-bent." Where it flourishes it proclaims that the land is in a poor condition, for it grows most luxuriantly when the land is in that state. It appears almost confined to England, as it is rare and local in Scotland. Unknown in Ireland. It is common in the south of Europe, but does not extend north of latitude 56°. It has not been found in America. In England it is found in Devonshire, Somersetshire, Sussex, Surrey, Kent, Essex, Suffolk, Norfolk, Cambridge, Bedford, Oxford, Leicestershire, Nottinghamshire, Warwickshire, Worces- tershire, Cheshire, Yorkshire, Durham, and Northumberland. Fields and way-sides. Panicle upright, slender, attenuated, compact, two or three inches long, deposited in short branches all round the rachis. Spikelets oval, consisting of one awned floret of an equal length with the calyx; compressed and numerous. Calyx consisting of 1£ ALOPECURUS AGRESTIS. two acute membranous glumes of the same length, joined near the base; keels hirsute, and having two green smooth ribs on each side. Floret of one palea, ovate -oblong, and having two green ribs on each side. Awn lengthy, slender, commencing slightly above the base of the palea, and extending considerably beyond it. Filaments three in number, slender. Anthers protruding, each end notched. Styles united and short. Stigmas long, downy, and two in number. Stem circular, upright, slender, rough, bearing three or four leaves, with rough, striated, swollen sheaths, upper sheath carrying at its apex a blunt downy ligule, and being longer than its leaf. Joints smooth. Leaves flat, rough, striated, and acute. Inflorescence simple, panicled. Length from one to two feet. Root small, fibrous, annual. This species is easily known by its attenuated panicles, which are often purplish in colour; and by the rough stem and sheaths, and the long dorsal awn. Dr. Parnell mentions that it can be recognised from A. pra- tensis in the slenderness of the panicle, in the spikelets being larger, the ligules considerably longer, the roughness of the stem and sheaths, and in the keels of the calyx being but slightly hairy; whilst in A., pratensis the ligule is short and blunt, keels of calyx and lateral ribs having long hairs, and the stem and sheaths being quite smooth. In A. geniculatus the stem and sheaths are also smooth, the awns shorter, the spikelets less, ligule shorter, calyx less acute and different in shape, and the panicle not so tapering. In A. fulvus the stem and sheaths are smooth, the panicle less tapering, spikelets less, ligule shorter. Flowers in the first week in July, and ripens its seeds in October. My thanks are due to Mr. Joseph Sidebotham, of Manchester, and to Dr. Wilson for good specimens of this Grass. The illustration is from Dr. Wilson's specimen. , -, N E U L 3 G A.

Two glumes nearly equal in size, upright, membra- naceous. Glumellas two, awnless, hairy; outer palea without lateral ribs. Leaves broad and flat. Only two British species. Its name is derived from the Greek, in allusion to the polished appearance of its seeds. THIS handsome Grass is not strictly a native of Great Britain, yet has now become naturalized in many parts of England and Scotland, probably owing to the extensive use of its seeds for feeding Canaries and other small birds. It appears to prefer rich ground, and near Beeston it is seldom found except in gardens and orchards. Native of the Canary Islands. It has also become naturalized in America. Probably it is not of any agricultural value. Panicle globular, upright, with brief branches. Spikelets oval, imbricated, flat, handsomely marked with yellowish green and white stripes, having one awnless floret. Calyx of two equal-sized compressed glumes. Floret consisting of two palese, the outer one egg-shaped, acute, hairy, having two membranous lance-shaped acute scales at the base, of half the length of 20 PHALARIS CANARIENSIS. the palea. Palea having the outer one longest. Seeds pol- ished. Stem slender, upright, smooth, having five or six leaves with rough inflated sheaths, the upper one being longer than its leaf, and having a white rounded ligule at its apex. Joints yel- lowish, naked. Leaves somewhat broad, lanceolate, acute, rather rough. Inflorescence panicled. Length from twelve to twenty- four inches. Root fibrous, white, annual. Flowers at the beginning of July, and ripens seed in last week in August. Specimens have been forwarded by Dr. Wilson, of Notting- ham, and Mr. Sidebotham, of Manchester, the latter from the road-sides in Cheshire, where it is not common.

It is known as the Common Sea Grass, the Marum or Matweed. The present species is protected by an Act of Parliament, on account of its great use along our coasts in Norfolk, and in Holland it is extensively grown, as also about Lytham, in Lancashire. Found on coasts of Northumberland, Durham, Lancashire, 24 AMMOPHILA ARUNDINACEA Cheshire, Denbigh, Anglesea, Merioneth, Essex, Kent, Norfolk, Worcester, Somersetshire, Devonshire, and Cornwall.

Glumes parallel, about equal in size, longer than the floret. There are six British species. Name derived from the Greek, formerly applied, it is conjectured, to the Reed Mace. A COMMON species, known as Timothy Grass, growing in moist soils, common in Great Britain in meadows and pastures. It has been recommended as a good agricultural Grass, from the nutritive matter in its flower stems, yet cattle are not fond of it, and it appears to be of too slow growth for the after- math, in order for it to become a remunerative Grass. Mr. Sinclair condemns its being grown alone in fields, but recom- mends it amongst other species as a valuable addition. Found in Lapland, Sweden, Norway, and North America. 26 PHLEUM PRATENSE. Panicle upright, compact, and cylindrical, green and white; length varying from two to five inches. Spikelets diminutive, abundant, arranged in pairs all round the rachis on brief foot- stalks, having one . slightly-awned floret considerably shorter than the calyx. Calyx consisting of two equal-sized glumes, having a broad membranous margin, keels furnished with short stout white hairs. Palea, outer one five-ribbed, egg-shaped, apex jagged, keel hairy. Floret consisting of two palea3, which are membranous. Stem circular, smooth, upright, bearing four or five leaves. Sheaths smooth, the uppermost one longer than its leaf, having a membranous ligule. Joints smooth. Leaves rough, flat, broadish, acute. Inflorescence simple, panicled. Length eighteen to twenty-four inches. K-oot creeping, some- what bulbous, perennial. Flowers in the third week in June, and ripens seed at the end of July. In A. alpinus the glumes are a third longer than their awns, in P. pratense about twice the length. In P. arenarium glumes acute and not awned, in P. pra- tense blunt and awned. In P. arenarium floret one-third of the length of the calyx, whilst in P. pratense about half the length of the calyx. P. Michelii has longer spikelets, acute glumes, and not awned. P. pratense, var. longiaristatum, Parnell, (the Long-awn ed Timothy Grass,) found in a damp wood near Edinburgh, dif- fers from the normal form by the awns of the glumes being almost as long as the glumes, and the root being bulbous. It does not flower till August. P. pratense, var. longiciliatum, Parnell, (The Bulbous Timothy Grass.) Stem near base prostrate, joints bent, awns of glumes short, root bulbous. Found in sandy situations. Flowering in the end of July. Fine specimens have been forwarded both by Dr. Wilson, of Nottingham, and Mr. Sidebotham, of Manchester.

EXCLUSIVELY a mountain Grass, flourishing in damp situations, at elevations varying from two thousand five hundred to three thousand five hundred feet. It is by no means a common species, being unknown either in England or Ireland. Mr. Dickson, the discoverer, first recognised Phleum alpinum near Garway Moor, whilst other explorers have found it on Craig- neulict, above Killin, Ben Lawers, Clova mountains, Breadalbane mountains, Feula Burn, Canlochen Glen, Glashieburn, Glen Fiadh, and Loch Brandy. Abroad it is plentiful in Norway, Sweden, Lapland, Switzer- land, Germany, and North America. As an agricultural Grass it is useless. Root slightly creeping, perennial, and somewhat tuberous. Stem upright, except near the base, where it is usually decumbent, smooth, circular in form, with four or five leaves, which are provided with polished striated sheaths. Uppermost sheath slightly inflated, and being longer than its leaf; capped with a short obtuse ligule. Joints smooth. Leaves broad, sharp pointed, smooth both above and below, except along the edges, where rough. Inflorescence simple, panicled. Panicle oval, tinged G 28 PHLEUM ALPINUM. green and white with dull purple, varying in length from half an inch to an inch and a half. Spikelets close together, dim- inutive and numerous. Calyx of two equal-length glumes, with wide membranous margins; the keels, which are green, are fringed with short white hairs; the glumes end in a rough awn, of rather more than half the length of the glume. Floret consisting of a pair of membranous paleae, the exterior one being egg-shaped, five-ribbed; keel hirsute; small rough dorsal awn; inner palea somewhat shorter. Length from six to twelve inches. Comes into bloom in July, and the seed becomes ripe before September. The present Grass bears some resemblance to Alopecurus alpinus, yet the latter species has the panicle silky, the glumes of the calyx destitute of awns, and the floret possessing only one palea.

Mr. Hudson procured it near Bristol, and on the heath at Newmarket; Mr. Crowe near Bournbridge. It has also been seen in Badminton Park. In Ireland it has been found near Belfast. It is a native of Belgium, Italy, Switzerland, Holland, Prussia, and France. Phleum asperum grows in arid sandy situations. Root perennial, consisting of a number of strong fibres. Stem circular, upright, exceedingly smooth, carrying four or five flat, rough, acute leaves, with rough tumid sheaths, the upper one extending beyond its leaf. Ligule bold and pointed. Joints four in number, covered by the sheaths. Inflorescence close, panicled, and from two to five inches in length. Spikelets abundant, compact, composed of two equal-length, rough, cuneate glumes, and one floret.

THE present species is a south of Europe Grass, which has been added to our British Flora, from the circumstance that Mr. Don discovered it amongst the rocks on the higher parts of the Clova mountains, in Scotland. It grows from one to two feet high. Phleum Michelii differs from P. arenarium, in having perennial roots, in the whole of the keels of the glumes being hirsute, and in the floret being entire at the apex instead of being notched. It is also readily distinguished from P. pratense, in having the glumes of the calyx acute-lanceolate, instead of being- obtuse; and from P. Boehmeri by the tapering glumes. No other botanist has been fortunate enough to discover it. It must be considered a doubtful British species. PHLEUM BOEHMERI. P. ARENARIUM. S3 PHLEUM BOEHMERI. SCHRADEE. KOCH. SMITH. KUNTH. HoOKEE.

It has not been discovered either in Scotland or Ireland. On the continent it is included in the fiora of Russia, Swit- zerland, Italy, France, Germany, Norway, and Sweden. Root fibrous and perennial. Stem upright, smooth, simple, slender, striated; upper portion purple and shining, having four or five leaves, with smooth rather tumid striated sheaths, the uppermost one much longer than its leaf, and having a broad obtuse ligule, which entirely encloses the stem, mostly four- jointed, the joints being all below the centre. Leaves rough on both sides and along the edges, flat, linear-lanceolate in form, except those near the base, which are narrower. Inflorescence compact, dense, panicled, cylindrical. Spikelets diminutive, very numerous, situated all round the panicle, consisting of two equal- sized glumes and one floret; glumes linear, the edges being white and membranous; apex oblique; floret awnless, and only 34 PHLEUM BOEHMERI. three-fourths of the length of the glumes, consisting of two equal-sized paleae, the exterior one being five-ribhed and roughish, the inner one membranous. Ovarium hirsute, scales bold, styles two, stigmas feathery, stamens three. Length from six to eigh- teen inches. Flowers in July, and the seeds become ripe about the middle of August. The present species differs from Plileum asperum in not having the glumes cuneate, in not having a long and pointed ligule, and in having the keels fringed. It differs from P. arenarium in having the floret entire instead of jagged at the apex, in the floret being much longer in comparison to the glumes, and in the inner edges of the glumes not being fringed with diminutive hairs as in P. arenarium. From P. Michelii in having more linear-shaped glumes, and in having only the upper portion of the keels hirsute, instead of throughout their whole length, as in P. Michelii; whilst from P. pratense it differs in the glumes being pointed and destitute of awns, and the inner edges ending obliquely instead of abruptly. Also in the exterior palea having the apex entire instead of jagged, as in P. pratense. The specimen illustrated was procured in Norfolk by Mr. Joseph Sidebotham, of Manchester. 35 PHLEUM ARENAPJUM.

It is to be met with on the coasts of Devonshire, Somersetshire, Sussex, Kent, Suffolk, Norfolk, Cheshire, Durham, and Northumberland. Also in Denbigh and Fifeshire; indeed it is by no means uncommon in Scotland, although local in Ireland. On the continent it is met with in various places in southern Europe. Inland it is recorded as growing on Swaffham and Newmarket Heaths. The leaves being harsh it is not an agricultural Grass. Root annual, consisting of numerous long simple fibres. Stem circular, smooth, and mostly having a purple tinge on the upper portion; joints naked. The stem bears four or five leaves, whose sheaths are slightly tumid, smooth, and striated, the uppermost sheath being above double the length of its leaf. Leaves rough both above and below, brief and broad. Inflor- escence simple panicled, the panicle being obovate-cylindrical in form, and upright in habit. Spikelets oval in shape, and numerous, consisting of one floret of one-third the length of the calyx, and awnless. Calyx composed of a couple of equal-sized mem- branous glumes, which are lanceolate in form. Upper portion H 36 PHLEUM ARENARIUM. of the keel and inner edges fringed. Floret consisting of two equal-sized membranous palese, notched at the apex, the outer palea five-ribbed; keel hirsute. The length of this Grass varies considerably, according to the support it is enabled to procure from the sandy ground. Sometimes it does not exceed three inches, at others it is five times this length. Phleum arenarium has much smaller spikelets than P. Michelii, it is notched at the summit instead of being entire, and the glumes not hirsute on the lower half of their keels. It differs from P. pratense in being smaller, the base of the panicle contracted, and having no awned floret. Comes into flower in the middle of July, the seeds becoming ripe in about a month.

Millet Grass, says Sir W. Hooker, either receives its name from mille — a thousand, on account of its fertility, or from mil — a stone, because of the hardness of its seeds. AN elegant Grass, growing commonly in damp woods and in moist shady situations. Of no agricultural value, but the seeds are a favourite food of small birds. Common in many portions of England, Scotland, and Ireland. Abroad it is found in Norway, Sweden, Lapland, North America, the United States, and in the Mediterranean Islands. Root fibrous, perennial, and branching. Stem upright, smooth, slender, shining ; and having four or five broad, flat, pale green, shining, smooth, lanceolate-shaped leaves, with sheaths that are smooth and striated, the upper sheath having an oblong membran- ous ligule. Joints smooth. Inflorescence compound panicled, or spreading, the panicle being glabrous, subverticillate, loose, and of large size, with lengthy slender branches arranged in alternate distant clusters along the rachis. Spikelets abundant, small, ovate in form, on delicate footstalks, and consisting of 42 MILIUM EFFUSUM. one awnless floret, hid within the calyx.

There is only a solitary representative of this genus in Great Britain, and that one very rare. The name is derived from the Greek, signifying a flaxen appearance, in reference to the present species — Stipa pennata. AN exceedingly rare British Grass, of but little agricultural value. It was first discovered on rocks in Long Sleadale, Westmorland, by Dr. Kichardson and Mr. Lawson, in the time of Dillenius, and from that time there seems to be no re-discovery of it. Lately, however, Mr. Joseph Sidebotham has forwarded me specimens gathered in corn-fields near Hebden Bridge, Yorkshire, where he informs me it is found growing wild, although rare. From the extreme beauty of this species it is extensively cultivated in our gardens, and its flowers gathered to ornament our drawing-rooms during winter. Stipa pennata grows in dry sandy situations. It is found in many parts of Germany. 44 STIPA PEN N ATA. Stem upright, circular, smooth, carrying four or five long, splendid, hirsute, rigid, and setaceous leaves, with rather rough sheaths, the uppermost one being longer than its leaf. Joints three or four in number, hid by the sheaths. Ligule of upper- most sheath hirsute, long and pointed. Inflorescence racemed, rising out of the highest sheath. Spikelets consisting of two nearly equal-sized, long, slender, hirsute glumes ; and one floret of only half the length of the glumes, consisting of two paleae, the exterior one sharp-pointed at the base, hirsute, five-ribbed, and ending in a considerable feather-like awn. The awn com- mences at the apex of the exterior palea, and usually twenty times its length; with the exception of that portion immediately about the base, it is feathery to the apex. Styles prominent, two. Stigmas feathery. Filaments capillary, three in number. Anthers notched at either extremity. Scales acute. Length about two feet. Root perennial and fibrous. This species does not flower till August, and its seeds become ripe about the middle of September. When gathered to decorate a room, this should be done at the commencement of September, before the seeds are ripe. The illustration is from a specimen gathered near Hebden Bridge, Yorkshire, by the late S. Gibson, and forwarded by Mr. Joseph Sidebotham, of Manchester. POLYPOGON MONSPELIENSIS, P. LITTORALI6.

It is a common species in England, Scotland, and Ireland, of no agricultural merit, being coarse and rough, with but little nutritive proper- ties. It will flourish in almost any situation, but prefers damp fields, where it grows into large tufts, and is known to agri- culturists as hassacks, a Grass difficult to destroy. It is a native of Norway, Sweden, Lapland, France, Italy, Germany, North America, and the United States. Nowhere does it flourish so luxuriantly as on the banks of a brook. The plant forms a large coarse tuft, and, as it is not eaten by cattle except when nothing else can be procured, a field in which it abounds has a singularly unsightly, and to farmers unwelcome appearance. The root is perennial and fibrous. Stem upright, circular, and 68 ARIA CJESPITOSA. x rough, and supporting four or five narrow, rough, coarsely-ribbed, acute leaves with rough striated sheaths, the uppermost one ex- tending considerably beyond its leaf, and having a lengthy, mem- branous, acute ligule at its apex. Joints smooth and very strong. Inflorescence compound panicled, and exceedingly handsome. Panicle when first expanded drooping, afterwards becoming upright, with the branches spreading in all directions. Branches and rachis rough. The spikelets are small and numerous, con- sisting of two or three horned florets. The calyx consisting of two equal-sized acute glumes, the upper one three-ribbed and the lower one destitute of lateral ribs. Of the two palese the exterior one of the lowest floret not equal in length to the glumes, membranous, base hirsute, destitute of lateral ribs, jagged on the summit; a slender awn starts from a little above the base as far as the apex of the palea. The inner palea rather shorter, linear, margin entire, and also membranous. Length from two to five feet. Aira alpina differs, on account of the awn commencing in that species slightly above the centre of the outer palea; whilst on the other hand, Aira flexuosa has the awn of the lower floret protruding above one-third its length beyond the glumes. There is a viviparous variety of Aira ccespitosa, known under the name of variety Vivipera, which has been found on the Clova mountains. It is an interesting ornamental variety, worthy of extensive cultivation as a border flower in gardens. Dr. Parnell describes two varieties, namely, " Longiaristata" and "Brevifolia" The variety Longiaristata differs in having the awn of the outer palea extending one quarter of its length beyond the apex of the palea, and in having the spikelets of a rich chocolate colour. Found on the mountains in Perthshire, between three and four thousand feet above the sea level. The variety Brevifolia is distinguished by the very short radical leaves. It is found growing near the summit of several of our highest Scotch mountains. This species usually flowers in the beginning of July, and ripens its seed early in September. Door-mats and basses are made of the hay of Aira ccespitosa, and for this the Grass is much in repute by rural cottagers. The illustration is from a plant growing on the edge of the lake at Highfield House. AIRA ALPINA. A . CARYOPHYLLEA. XXI 69 AIRA ALPINA. LINNAEUS. HOOKER AND ARNOTT. PARNELL. BABINGTON. LINDLEY.

THIS reed-looking Grass, perhaps better known as the Purple Melic Grass, is abundant throughout Scotland, England, and Ireland, growing on damp heathy moors. It is of but little agricultural value. In the Orkney and Shetland Islands the stems are made by the fishermen into ropes, whilst in England they are manufactured into cheap brooms. It occurs in Lapland, Norway, and Sweden, and to the most southern portions of Europe. Stem upright, circular, smooth, being bulbous at the base, carrying three lengthy, narrow, linear, taper-pointed, acute, rough leaves, with smooth striated sheaths, the uppermost one shorter 80 MOLINIA CJERULEA. than its leaf, bearing at its apex a diminutive ligule. Joints smooth, and close to the base. Inflorescence compound panicled. Panicle upright, lengthy, narrow, and compact; branches slender, rough, and situated on the rachis in bunches at certain intervals. Spikelets numerous, small, chiefly composed of two, yet some- times of three, awnless florets, purplish in colour, and considerably longer than the glumes. Calyx smooth, of two unequal, acute glumes. Florets of two equal-sized palese, exterior one of basal floret smooth, three-ribbed, and acute; inner one having two bold marginal ribs of a green colour. Root consisting of a multitude of strong fibres, perennial. Length from one to two feet and a half. Flowers towards the end of July, and ripens its seed at the close of August. There is a variety known as Molinia depauperata, which Lindley and Parnell give as a distinct species, and known as the Tawny Melic Grass. It differs in being usually less in size, and having the leaves of the stem extending beyond the panicle, in the calyx having only one floret, the outer palea being five- ribbed. It was discovered on the Clova Mountains, (three thousand feet above the sea,) by Mr. Donald Munro. There is another variety more dwarf and compact, known as M. ccerulea, var. breviramosa, distinguished by its dwarf habit and dark purple inflorescence — a common Grass on moors. The specimen for illustration was forwarded by Mr. Joseph Sidebotham, of Manchester. 81 MELICA NUTANS. LINNAEUS. HOOKER AND ABNOTT. SMITH. PAENELL. G-BEVILLE. LlNDLET. KOCH. WlLLDENOW. CuBTIS.

A GRASS as yet of no agricultural value, growing in damp shady woods at an altitude of about five hundred feet above the sea, and not found higher than two thousand feet. It is an early Grass, doing well under cultivation, and therefore may prove of use to the farmer. In Scotland it occurs in Aberdeenshire, Forfarshire, Fifeshire, and near Edinburgh. In England, in all the northern counties and Nottinghamshire, Derbyshire, Worcestershire, Suffolk, and Hertfordshire. In Wales, in Denbigh. Abroad, it is a native of France, Italy, Germany, Denmark, Sweden, Norway, and Lapland. This lovely Grass is very ornamental when growing luxuri- antly, and no one can fail being struck with its beauty after seeing it growing, as it does, in a damp wood near Ambleside. p 82 MELICA NUTANS. The wood seemed as if meant for Fairyland, each raceme of bloom bearing a number of bells, all hanging in one direction. Stem upright, slender, roughish, bearing four or five long, narrow, acute, flaccid, pale green leaves, with rough striated sheaths, the upper one shorter than its leaf, and having at the apex a brief obtuse ligule. Inflorescence racemed. Raceme long, mostly of ten spikelets placed on short rough footstalks. Spikelets large, ovate, pendulous, and consisting of two perfect and one imper- fect floret. Calyx of two broad, reddish brown, smooth, five- ribbed glumes. Florets of two palese. Length from twelve to twenty-four inches. Some specimens gathered near Ambleside were above three feet in length. Root perennial and creeping. Flowers at the end of May, and becomes ripe in July. This Grass is known from Melica uniflora in the inflorescence being racemed instead of simple-panicled, and in the calyx containing two perfect florets. The most unaccustomed eye can at once recognise the difference between these two species. My thanks are due to Mr. Joseph Sidebotham for specimens gathered near Halifax, and from which the illustration is taken. MELICA UNIFLORA. LlNNJEUS. HOOKEE AND AENOTT. SMITH. PAENELL. GrBEVILLE.

Great Britain only possesses one species, namely, Sierockloe borealis, which has been found in Scotland. It is an abundant Iceland plant. THIS very rare species, although one of our earliest, yet it is not a valuable Grass. It is confined to Scotland, having been found by the late Mr. G. Don, in a mountain valley called Kella, near the Spittle of Glen Shee, Forfarshire, and near Thurso, Caithness, in 1854, by Mr. Eobert Dick.

Aquatica — Aquatic. POA, LinncBus. — The Meadow Grass takes its name from the Greek, sig- nifying grass, or to feed, on account of the whole genus being valuable for pasturage. There are fifteen British species. A VERY common handsome Grass, growing in wet situations, such, as undrained meadows, and along the edges of water. It is a valuable agricultural Grass for damp situations, as it can be mown twice a year, yields a heavy crop, and cattle are fond of its sugary flavour. In Scotland it is found near Edinburgh, Forfar, Perth, and Dumbarton. In England, in the counties of Devon, Somerset, Kent, Surrey, Sussex, Middlesex, Norfolk, Suffolk, Cambridge, Oxford, Bedford, Worcester, Gloucester, Warwick, Nottingham^ Leicester, York, Chester, Durham, Westmorland, and North- umberland. This summer I found it very abundant and large at Amble- side, in Westmorland, and in many places round Nottingham. Rare in Ireland. 104 POA AQTTATICA. Abroad it is a native of France, Italy, Germany, Norway, Russia, Sweden, and North America. Stem erect, strong, smooth, striated, tearing seven or eight flat, lengthy, broad, rough-pointed leaves, with harsh sheaths, the upper one longer than its leaf, and having at its apex a brief, broad ligule. Joints smooth, six to eight in number. Inflorescence compound-panicled. Panicle upright, large, branches rough, situated alternately in half-whorls on the rachis. Spike- lets many, upright, having from four to eight florets, the upper ones large and ovate, the others smaller and narrower. Calyx consisting of two membranous, unequal-sized, blunt glumes, destitute of lateral ribs. Florets not webbed, consisting of two awnless paleae. The exterior palea of lowest floret seven-ribbed. Stigmas compound and plumose. Styles larger than the stigmas. Length from three to six feet. Root perennial and creeping. Flowers about the middle of July, and ripens its seed in a month.

Root perennial and fibrous. Flowers at the beginning of July, and ripens its seed in a month. Known from Poa maritima by the rough rachis and branches; from P.procumbens by the spreading branches of the panicle and the ribs of the glumes not being prominent; from P. trivialis by its smooth sheaths, blunt ligule, linear spikelets, and florets not being webbed ; from P. annua in the roughness of the inner surface of the leaves and the branches of the panicle; and from P.pratensis in the linear spikelets, obtuse glumes, and in the florets not being webbed. Variety Obtusa found at Breeden, Leicestershire, by Mr. Babington, where it was growing in great quantities in the fields. The spikelets are larger, ligules shorter, and outer palea broader and more obtuse. Variety Minor also gathered at Breeden, by Mr. Babington. It is more dwarf, and the spikelets of fewer florets.

Amongst our indigenous species are Avena fatua, A. strigosa, A. pratensis, A.pubescens, A.flavescens, and A. planiculmis; the latter has only been collected by one botanist, Mr. Murray, who discovered it at Glen Sannox, in the Isle of Arran. THE Wild Oat-Grass is a common species in England and Ireland, yet much rarer in Scotland, It chiefly grows in corn- fields, and is a troublesome weed. The awns, from their extreme sensitiveness to the moisture of the air, are manufactured into Hygrometers. The florets are also occasionally used as artificial flies for trout- fishing.

IN the present Work there are several species not enumerated, some being of doubtful origin, and others so exceedingly rare as scarcely to be procured: they are mentioned briefly in the addenda. At the con- clusion of this "Work the author intended to have commenced a Natural History of those Foreign Grasses that were remarkable for their beauty, singularity, or economic values; this latter Work, however, will be deferred, as the author cannot devote the time requisite for this un- dertaking at the present moment. In order to distinguish the species of British Grasses, the author has appended a COMPAEATIVE ANALYSIS, ARRANGED BY MR. EALFS. OEDEE I.— MONOGYMA. Stigma one. . . Stigmas two. ...
