Of this genus there is only this one species, and ," this is the only British plant of this Order : it grows 0ne stamen. in ditches and stagnant waters, and blossoms in June and July. It has no corolla, but at the base of its long linear leaves it produces a Calyx with one stamen and four pistilla, which is the fertile flower, and a Calyx with one stamen without any pistilla, which is the barren flower, constituting the character of the Class : with the figure of the plant, these parts are represented enlarged for the sake of illustration. This plant was named by Micheli, in honour of Giov.Jeronymo Zannichelli., an apothecary of Venice, 4 MOXOECIA. author of many works upon different branches of na- tural knowledge. BREAD FRUIT TREE, Artocarpus communis, is supposed to be of this Order. This celebrated tree has been brought into particular notice since the dis- covery of Otaheite and the Sandwich Islands, where the fruit is eaten as bread. It is also a native of many islands in the East Indies, as Java, Amboyna, Banda, Sec. but in those islands the tree was not cultivated, and little use was made of the produce. The tree is described to be of the size of a mid- dling Oak, and the fruit to be of the size and shape of a child's head, growing on boughs like apples, with a hard, thick, and tough rind. Whea it is ripe it is yel- low and soft, and the taste sweet and pleasant. It is gathered when full grown, while it is green and hard, and baked in an oven, which scorches the rind and makes it black ; the outside black crust is then scraped off, and there remains a tender thin crust; the middle, soft, tender, and as white as snow, and somewhat of the consistence of new bread. In this sort, which is the best, there is neither stone nor seed in the inside, but all of one pure uniform substance. It requires to be eaten new; if it be kept more than twenty-four hours it becomes dry and choaky, but very pleasant before it is too stale, having some- what of the taste of a Jerusalem Artichoke. This fruit lasts in season eight months in the year, during which time the natives of the islands in the South Seas, where the tree is cultivated, eat no other sort of MONOECIA. 3 food of the bread kind, unless Yams'and Bananas may be considered as such. Three trees are supposed to yield sufficient nourishment for one person. There are several species or varieties of this tree, and die fruit of some, has a core, and some, long ob- long seeds, almost as large as chesnuts. This tree is useful not only for food, but also for clothing, the inner rind of the young bark being manufactured into a kind of cloth. In the year 1793 Captain Bligh took three hun- dred and forty-seven of these trees from the South Sea Islands to Jamaica, and about the same number to St. Vincent's, in the West Indies, where they continue to grow and bear fruit; but the hurricanes and tem- pests of that climate have been unfavourable to their increase in the degree that was expected, and the na- tives still prefer the yams of their own country to the Bread-fruit. ORDER 2. No British Plant of this Order. ANGURIA, of which there are three species, is a diandria native of St. Domingo, a perennial plant, climbing; „ ~ — . trees by the means of long tendrils to the height of twenty feet. The old stems are woody and leafless; the young ones, round, pliant, smooth, and leafy; 0 MONOECIA, the flowers, which are red or of a deep orange colour, are without scent. The fruit is green, with longitu- dinal white streaks, an inch in length, and die thick- ness of the middle finger. The seeds are white. It blossoms in September, and the fruit ripens in December. TRTAN. DRIA. Three Stami na. ORDER 3. SEDGE. Carex. Of this Genus Professor Martyn describes ninety-seven species, of which Dr. Smith enumerates fifty-two which grow wild in Great Bri- tain. This sedge, Carex acuta, is found on the banks of rivers, and will also grow in the middle of a ditch, or pond, and if suffered to increase, quickly fill up any piece of water. It has creeping roots, which easily make their way through any moorish ground, and hence the Carex is often found in meadows, though, in such situations, of less luxu- riant growth. From the joints of its horizontal roots it sends up stems, some producing flowers with stamina only, and others bearing flowers with only pistilla. In the annexed plate these two different flowers have the appearance of being on different plants, from the want of the connecting root, which has been omitted to increase the size of the represen- tation. In a mild season it blossoms in April, and ripens its seeds in June and July. In Herefordshire, and other Hop counties, the Sedge is often used for tying up young Hop wires to MOXOECIA. / the poles, and it is also employed to make common chair bottoms. Of its use and importance in Lapland, Linnneus has given a very interesting account, of which this is Mr. Curtis's translation. " Thou wilt wonder, perhaps, carious reader, in what manner human beings are capable of preserving life during an immense severity of a winter's frost in Lapland, a part of the world deserted on the ap- proach of winter by almost every kind of bird and beast. " The inhabitants of this inhospitable climate are obliged to wander with their Rein- deer flocks con- tinually in the woods, not only in the day time, but through the longest winter nights ; their cattle are never housed, nor do they eat any other food than liver- wort 3 s hence the herdsmen, to secure them from wild beasts, and other accidents, are of necessity kept perpetually with them. The darkness of their nights is, in a degree, overcome and rendered more tolerable by the light of the stars reflected from the snow, and the Aurora-borealis, which in a thousand fantastic forms nightly illumines their hemisphere. The cold is intense, sufficient to frighten and drive us foreigners from their happy woods. No part of our bodies is so liable to be destroyed by cold as the extremities, which are situated farthest from the heart; the chilblains of the hands and feet, so frequent with -■» This liver-wort is the Rein-Deer Lichen, Class XXIV. 8 MONOECIA. us in Sweden, sufficiently indicate this. In no part of Lapland do we find the inhabitants affected with chilblains, though in respect to the country one would expect them to be peculiarly subject to this disease, especially as they wear no stockings, while we clothe ourselves in one, two, and even tree pair. j ZAM*1CHE]LLIA FAJLUSTIRIS ' -^hat Tree ARTOCAjRJFITS communis CLASS MI ORDER 2 1 A^GFRIA A^GTURIA FEDATA S^SsSS\ s^s^s^*! class in ORDER 3 §EB &E V JN 'CARJEX ACUTA ■^V/\^\^V CLASS XXI ORDER 4 u FAFER MIHLBEIUKY T1LEIE I MOMS FAFYMI1FIEKA CLASS XXI ORDER 5 NEPHELIFM, V KEFHEJLIUM JECHIHATUM Vvy^Av>^= S^Ss^K N ■CIASS XXI ORDER 6 ZI^A^IA "VI ZIZAKIA AQTTATICA ■'v^, vr CLASS XXI ORDER 7 V COMMON AlMOW«EEAI)| 1- N 3A&ILTTARIA § A I > ITTIFOILltA AAM. 5555 CIAS SMI ORDER 8 I WIJLJD FIME«T1REE F»TUS SELVES TRIS DIOECIA.

No British Plant of this Order. NAJA.S. Of this Genus there is but this one monan- species. According to Dr. Smith this plant is a good DRIA: and immutable example of this Order, and the only one stamenj one of which he seems to be certain. It is found wild in the canal between Pisa and Leghorn, and in the Rhine near Basle: it has no Calyx nor Corolla. In the Histoire de IS Academic Francois, pub- lished in the year 1719, there is a small figure of this plant which bears the Pistilla, from which the an- nexed figure is copied, and to the present time, no other has been published that I am acquainted with. 16 DIOECIA ORDER 2. VALLISNERIA. This is an aquatic plant of diandria which there are two species: it grows in great quan- Twostamina. tities in Italy, in the canal and ditches in the neigh- bourhood of Pisa, and also in the Rhone. Its natu- ral habits are highly curious and interesting. The flowers which bear Stamina are produced at the bot- tom of the water till they come to maturity, but with- out expanding; they then separate from the footstalks on which they are borne, and rising to the top, open suddenly with an elastic force, and in this state swim at large on the surface. The other plant producing the Pistilla, bears its flowers on a spiral stem, which at the same season, has the power of uncoiling ac- cording to the depth of the water, so as to arrive at the surface at the same time, and thus receive the Pollen from the Antherae of the floating Stamina. The flowering season being past, the spiral stem then contracts and completes its fructification at the bottom : the other flowers with Stamina, are dispersed and perish. The plant with staminiferous blossoms is marked N°l. the other, which only produces Pistilla, and con- sequently the seed, is marked N" 2. The flowers producing Stamina are white, those producing the Pistilla are purple. D10ECIA. 17 LEAST WILLOW, Sallv herlacea. This is the least of all trees ; the stems of which, though scarcely two inches high, are truly woody and peren- nial. The woody roots are of a greater extent, creep- ing and running deep into the rocky soil which this species inhabits, about the tops of the highest moun- tains in Scotland, Wales, and Cumberland. It has been gathered on Ben Lomond. This Genus has not yet been well investigated ; at present there are enumerated fifty-three species, of which forty-five are English 5 and this is the only British Genus of this Order. These plants are very easily propagated, and remarkably tenaceous of life; hence they have been often used in experiments to ascertain some principles in vegetable ceconomy. Van Helmont, a celebrated physician and chemist, planted a willow, (the species is not defined) weigh- ing fifty pounds, in a certain quantity of earth covered carefully with a sheet of lead : he kept it in this state for five years, watering it with distilled water; and at the end of that time the tree weighed 169 lbs. 3 oz. The earth in which it had vegetated, being weighed at the same time, was found to have lost no more than three ounces. Boyle repeated the same experi- ment upon a plant, which at the end of two years had gained fourteen pounds without the earth in which it had vegetated having lost any perceptible portion of its weight. These facts serve to shew how very impor- tant air ard water are to the increase of vegetation; but by what law of nature these elements are con- VOL. III.

The plant itself is Three stami- biennial, and for one winter preserves its leaves as an ever-green. This plant, though not very common, is found in shrubby heaths and in thickets in so many parts of England as to render the indication of any particular place superfluous. It is often cultivated in gardens. Of the Ruscus there are five species, but the one here represented is the only one a native of England. Of this Order there is only one other Bri- tish genus, Empetrum, of which there are two species: the Empetncm nigrum only, is indigenous to Great Britain. The leaves are tipped with a sharp thorn, and bear a solitary flower about the middle of the upper side, whose footstalk passes down between the inte- guments of the leaf to its base. Virgil, in his seventh Eclogue, has introduced the Ruscus* as an emblem pre-eminently repulsive, from the sharp and thorny character of its leaves. I lmino ego sardo'is videar tibi amarior herbis, Honidior rusco, projecta vilior alga : Si nv.hi non hacc lux toto jam longior anno est. £cl. vii. DIOECIA. 19 ORDER 4. MISSELTOE. This plant, instead of rooting and ™™£N- 1 ° DRIA. growing in the earth, fixes itself into the branches of trees, where it spreads and forms a bush, conspicuous in winter, when it has a yellowish hue. In Worces- tershire and Herefordshire it is very common in orchards and hedge-rows, on apple-trees. In the nor- thern counties it is less frequent, and has not Deen re- marked to grow in any part of Scotland. In England it is rarely found on the Oak, but in Hungary it is said, by Clusius, to abound on that tree. It blossoms in May, and produces berries semi- transparent, full of a sweetish viscid pulp, enclosing one seed j of these berries bird-lime is made, which would seem to be a very old application of their use, as the English name is derived from a Saxon word, signifying" bird-lime. The Misseltoe is the golden bough of Virgil, which was iEneas's passport to the infernal regions.x It was always considered as sacred by the ancient Druids, and the tree on which it grew, if it were an oak. The use that was made of the berries by the ancient Romans, and the religious veneration attached to the plant by the Druids, are thus recorded by Pliny the Elder : " Bird-lime is made of the berries of the Mis- seltoe, which are collected unripe, in the season of har- vest -, if they are left to be exposed to showers, they are x /En. lib. vi. ver. 130. ~tJ BIOFXIA. increased in size,, but are less viscous, They are driedj ihen pounded and steeped in water for about twelve days to putrify. Afterwards they are put into ran- ning water and pounded, by which the pulp becomes clammy. When this is used to ensnare birds, by en- tangling their feathers, it is mixed up with walnut oil. Nor must we, on this subject, omit to mention the admiration of this plant shewn by the people of the Gallic provinces. " The Druids (so they term their Priests) hold nothing more sacred than the misseltoe, and the tree on which it is produced, if it be an oak. Hence they choose thick groves of Oak, and perform no sacred rites without this bough. (So that, by interpreting the greek, they appear to derive their name, Druid, from this circumstance.) Indeed whatever grows upon the oak they consider as sent from heaven, and as a sign that the tree is adopted by the Deity himself. It is however very rarely found upon it, and when discovered is procured with much superstitious reve- rence ; and especially on the sixth day of the moon, which with them makes the beginning of their months and years, and after the thirtieth year, of their aoe; because the moon is then supposed to have ac- quired sufficient strength, and at the same time not completed its half orb/ Great virtues are attributed z The calculation of the Druids, agreeable to this statement, shews that they considered the moon to have arrived at half her age in seven days, being the midway between the change and full. It is also curious to observe, that their age nearly DIOECIA. 2J to it, and the plant is called by a word in their tongue signifying, healing all things. When it is found, sacrifices and feasts being prepared under the Oak, two white bulls are brought, whose horns are bound for the first time with garlands : the priest clothed in white, ascends the tree, and with a golden pruning- hook cuts off the Misseltoe, which he receives into his white cassock. The victims are then killed, and offered up with prayers that God would prosper those on whom he has bestowed so precious a gift. " An antidote against sterility and ail poisons is ascribed to the virtues of this plant ; so great is the superstition of nations concerning frivolous things."- Of the Genus Viscum there are twelve species, all exotic except this Viscum album. Of this Order there is only one other British Genus Myrica, of which there are nine species, but the Myrica Gale is the only species indigenous to Great Britain. CRDER 5. HEMP. The native soil of this plant is not known with certainty. Linnaeus gives it to the East Indies and Japan. There can be little doubt but that the corresponded to that of the ancient greeks ; as by Herodotus we learn, that with them three made a century, a Piinv, lib. xvi.c 44. PEKTAN. DR1 A. rive Stamina. 22 PIOECIA. greeks took their name from the eastern Kanop, or Cannab, and that the plant originally came into Eu- rope from those countries. It grows in England, in general, to about a man's height, though it has been sometimes known to grow as high as fourteen feet.b It is fit for pulling towards the latter end of July, thir- teen or fourteen weeks after the seed has been sown. When pulled it is immersed in water and broken, combed, and dressed, nearly in the same manner as flax. It is of the greatest importance in the Navy for sails, and all kinds of cordage are made of it, and some kinds of coarse cloth for domestic purposes. Bombasin is b By a paper read in the Royal Society, 178 2, it appears, that in China, Hemp grows more luxuriantly than with us, or (hit the kind cultivated there is different from ours. A few i of Chinese Hemp seed were sown in England on the 4th of April 1762, which produced luxuriant plants several of them growing to more than fourteen feet in height and nearly seven inches in circumference by the middle of October following, at which time they came into bloom. There were from 30 to '10 lateral branches on each plant, which were set off in pairs, one on each side of the stem pointing horizontally ; the others •at about five or six inches distance from them, pointing in dif- ferent directions, and so on to the top ; the bottom branches of some measuring more than five fett, the others gradually diminishing in length towards the top, so as to form a beautiful cone when in flower, but which was unfortunately nipped by a few nights frc.=t towards the end of the month ; and the plants began to droop at the beginning Of November, when they were pulled up by the roots. These plants grew nearly eleven inches per week.— Philoso- phic::! Transactions, vol.lxxii. p. 16. D10EC1A. 23 also made of Hemp prepared in a peculiar way with sulphur, which gives it a silky gloss. The branches or stalks of common broom, when dried in the sun, and treated like Hemp, produce threads which may be spun, and worked into a coarse cloth. In the country they are made into besoms, from this, its familiar use, Linnaeus has derived the specific name of this species, and called it spartium scoparium? sweeping-broom. From the seeds of Hemp an oil is extracted. The seeds themselves are reckoned good food for poultry, and are supposed to occasion hens to lay a greater quanty of eggs. Small birds., in general, are very fond of them, but they should be given to caged birds with caution, and mixed with other seeds. A very singular effect is recorded, on good autho- rity, to have been sometimes produced by feeding Bullfinches and Goldfinches on hemp-seed alone, or in too great quantity : that of changing the red and yellow on those birds to total blackness. The Hop plant is the only British genus of this Order of which Botanists make but one species. Hu- mulus lupulus. ORDER 6". BLACK BRYONY. Of this °;enus there are nine- iilxan- teen species* but this alone is common in shady duckets, hedges and woods, in most parts of England, and blossoms in June. The root is somewhat black ex- ternally, whence its ancient name Bryonia nigra, and Six Stamina. 24 DIOECIA. the English name Black Bryony. The stems of this plant twine about every thing in their way, and ascend without tendrils to the tops of shrubs and bushes, and with festoons of red berries decorate the autumn. This is the only British plant of this Order. POLY AN- Dill A. Stamina nu- merous. ORDER 7. COMMON FROG-BIT. Of this genus there is only this one species: it floats on the surface of ditches and slow streams, almost covering the water with its leaves, and blossoms from June through the autumn.

Of this tree there are four species but this is the only one common to Europe ; the other three are natives of Japan. The proper wild situa- tion of the common Yew is in mountainous woods, and more particularly in the clefts of high lime-stone rocks. It blossoms in March and April, and the fruits DIOECIA. 25 ripens in autum. The Calyx, which is originally small, and of a green colour, sustaining an oval flat- tish seed, at length becomes red, soft, and full of sweet slimy pulp, not unwholesome, though the leaves are very poisonous. The wood, amongst our ancestors, was used for making bows, and the tree is supposed to have been planted in church-yards to foster its growth for that purpose ; but I suspect the same feelings that introduced the Cypress in the East to gloom the repositories of the dead, had a principal share in this custom, which has prevailed in the nor- thern nations j it has, however, been thought to be a symbol of immortality, the tree being of so lasting a quality, and always green. The Yew, though of slow growth, sometimes ar- rives at a very considerable size. Pennant mentions one in Fontingal church-yard, in the Highlands of Scotland, whose ruined trunk measured 56^ feet in circumference Camden tells a story of a Yew that was held in such veneration in Yorkshire, in consequence of the death of a Virgin, whose head was said to have been hung upon it, by a profligate priest, suspended by the hair, that an obscure village, called Horton, became so great a resort of strangers from all parts, that buildings were yearly increased for their accommodation, and thus originated the great manufacturing town of Hali- fax, the derivation of which is, Holy Hair. Fax, Camden says, is now used by the English, on the other side of Trent, to signify hair: Fax, is hair in the Saxon language. , 26 D10ECIA. In the mythology of the ancients, Smilax, a beau- tiful shepherdess, who was beloved by Crocus, was metamorphosed into a Yew-tree, and Crocus was changed into a flower which has since borne his name, well known to us as the harbinger of spring. It has been much debated whether the yew tree be poisonous or not; but, from numerous and well- attested facts, the poisonous quality of its leaves is now well ascertained, and if eaten by horses and cows, very small quantities produce certain death j neverthe- less, some intelligent persons assert, that the branches of yew, wrhile green, are not noxious, because yew- trees are known to stand for many years in fields, and no bad consequences have ensued; but this may be accounted for from the natural habits of cattle to reject it, and no pressing necessity occuring to oblige them to resort to it. Professor Martyn says, from his own knowledge, that a horse tied to a yew hedge, or to a faggot-stack of dead yew, has been found dead, be- fore the owner could be aware that any danger was at hand! that he lias several times, among his friends, been a sorrowful witness to losses of this kind ; and in the Isle of Ely he had once the mortification to see nine young bullocks of his own all lying dead in a heap, from browzing on a Yew hedge in an old gar- den into which they had broken in snowy weather. It is said that turkies, sheep, and deer, will crop these trees with impunity. Yew-leaves are certainly fatal to the human spe- cie. Caesar, in his Gallic war, relates that Cativolcus, joint king of the Eburones, killed himself with yew, DIOECIA. 27 taken as poison .b In Sussex, a few years ago, a young lady and her servant who had, by mistake, taken a decoction of yew leaves for the ague at night, were both found dead in the morning ; and Dr Per- civai has recorded a case of three children who were killed by a spoonful of the green leaves injudiciouly administered to them as a medicine : to these might be added other well authenticated facts of the same kind, to shew its powerful effects as a poison on the human constitution. As early as the days of Theophrastus, the fruit of the yew was eaten, and considered as harmless, and down to our own time I know of no fact to invalidate his testimony. Every one may remember, with old Gerarde, who, with his usual simplicity says, " when I was young and went to school, I and divers of my school- fellows did eat our fills of the berries of this tree." Yet, for reasons which I have already given, respecting the berries of the Cherry-laurel, it may be as well to reject them. PITCHER-PLANT. Nepenthes distillatoria. This very curious and singular plant is a native of many parts of the East Indies. It is found in the island of Amboyna and Ceylon. It grows in vallies, b Cativolcus, rex dimidiae partis Eburonurn, qui una cum Ambiorige consilium inierat, aetate jam confectus, quum labo- rem aut belli aut fugae ferre non posset, omnibus precibus detes- tatus Ambiorigem, qui ejus consilii auctor fuisset, taxo, cujus magna in Gallia Germaniaque copia est, se exanimavit.

The Leaves, which are alternate, have nerves running through the middle of each, ending in a long tendril, generally twisted j to which hangs a hollow receptacle, or bag, whose aperture at the top is covered with a leaflet representing a lid. This receptacle is four or five inches long, and is generally half filled with a sweetish fluid as clear as water, and what evapo- rates or is exhaled in the day time, is again restored in the night, by a secreting power in the plant it- self. In the Botanical Library at Oxford there are good dried specimens of this plant, which I have seen,; and though Linnaeus visited England, partly on purpose to see that Hortus siccus, yet he must have overlooked these specimens, as with some hesitation he has made this plant gynandrous in his system, which, if he had seen them, would have removed his difficulty.

Of this Class and Order Linnaeus has arranged the extensive Genus Mimosa, of which Professor Mar- tyn makes 85 species. The common Sensitive-plant, Mimosa pudica, is the most common in Brazil, where it is a native, and in the hot houses of English gar- 30 P0LYGAM1A. dens. The annexed figure is a representation of a branch of the shrub to shew the form and arrange- ment of the leaves, which have so remarkable a cha- racter as to contract upon the slightest external stimulus. It appears from the works of Theophrastus, that the Sensitive-plant was not unknown to the ancients : he speaks of it as growing about Memphis in Egypt; and Pliny also speaks of it as a plant named from con- tracting its leaves at the approach of the hand. The interesting phenomena connected with its irritability, have been alike the subject of curiosity and scientific investigation; and Professoi Martyn's observations, for more than forty years, during which time he culti- vated these plants, will serve to illustrate their general habit and character. « They are more or less susceptiUe of the touch or pressure, according to the warmth of the air in which they grow, for those plants which are kept in a warm stove contract their leaves immediately on be- ing touched, either with a hand, a stick, or any other thing, or by the wind blowing upon them : some of the sorts only contract their small leaves, which are placed along the midrib; others not only contract their small leaves, but the footstalk also declines downward on being touched; the first are called Sen- sitive, and the second Humble Plants ; but when these plants are placed in a cooler situation they do not move so soon, nor contract so closely, as those which axe in a greater warmth ; and those that are en- POLYGAMIA. tirely exposed to the open air have very little motion, bat remain in one state, neither expanded nor closed, but between both, especially in cool weather 5 nor do these shut themselves at night, as those which are in a warm temperature of air. " Secondly, it is not the light which causes them to expand, as some have affirmed who have had no experience of these things ; for in the longest days of summer, they are generally contracted by five or six o'clock in the evening, when the sun remains above the horizon two or three hours longer ; and, although the glasses of the stove in which they are placed are co- vered close with shutters to exclude the light in the middle of the day, yet if the air of the stoves be warm the leaves of the plant will continue fully expanded, as I have several times observed. Nor do these plants continue shut till the sun rises in the morning, for I have frequently found their leaves fully expanded by the break of the day ; so that it is plain the light is not the cause of the expansion, nor the want of it the cause of their contraction. " I have also observed, that those plants which are placed in the greatest warmth in winter, continue vigorous, and retain their property of contracting on be- ing touched j but those which are in moderate warmth , have little or no motion. " When any of the upper leaves of these plants are touched, if they fall down and touch those which are below them, it will occasion their contracting and failing, so that by one touching another they will con- 32 POLYGAMIA. tinue falling for some time. When the air of the stove in which these plants stand, is in a proper tem- perature and warmth, the plants will recover them- selves, and their leaves will fully expand in about eight or ten minutes. I have frequently watched them as they have been recovering, and have always found it has been by a vibratory motion, like the in- dex of a clock. " Some of the sorts are so susceptible of the touch that the smallest drop of water falling on their leaves will cause them to contract, but others do not move without a much greater pressure.

The wood is hard and the branches of the preceding year termi- nate in stiff thorns. The berries, which are very juicy, acrid, and astringent, are much eaten by the Tartars, and used as an acid sauce by the poorer peo- ple of Sweden and the south of France. They are also the principal food of the pheasants about Mount Caucasus. The fishermen of the Gulph of Bothnia prepare a sauce from them, which imparts a grateful flavour to fresh fish ; the plant is also used for dying yellow. ORDER 3. No British Plant of this Order. CULTIVATED FIG. In strict conformity to trioecia. the data laid down by Linnaeus for this Order, no Different plant has been found ; the structure of the blossoms J^elepi in the Fig being alike in all, but a trifling variation in rate Plants- the calyx has induced subsequent Botanists to con- tinue the Fig-tree here, where Linnaeus originally placed it, though not correctly, according to his own rule, as expressed in the margin. The singular structure and ceconomy of this plant deserve particular attention. The fruit, or Fig itself, not only contains the seeds, but is at the same time the receptacle, enclosing and sustaining the flowers within it. VOL. III. c 34 POL YG AM I A. The annexed figure is the representation of the common Levant Fig, which has within it blossoms bearing only pistilla, and. called by way of pre-emi- nence the Cultivated Fig, to distinguish it from an- other species called Caprificus, or Wild Fig. The wild Fig-tree bears successively in the same year three sorts of Figs. The first appears in August, and in the months of October and November gradu- ally falls away j the second sort makes its appearance towards the end of September, and remains on die tree till May^ in which month a third sort of trait puts forth, much larger than either of the others, which by the Greeks is called Orni. These fruits have all a sleek even skin, of a deep green colour, and con- tain in their dry mealy inside, blossoms, some with stamina only, and some with only pistilla, enclosed in the same Fig, placed upon distinct footstalks, the for- mer above the latter," but none of the fruits are good to eat ; nevertheless all of them are said to be essen- tial to the breeding and nourishing in succession a little gnat, on which the maturity of the cultivated Fig depends. From the earliest antiquity the use of the wild Fig- tree to ripen the cultivated Fig was well known, and great care was taken to propagate the Caprificus for that purpose, as at this day it is in the Archipelago. u In the Illustrations of the different pistilla of different flowers, N° l. is a pistillum enlarged of the Ons'i; and Nu 2. apistillum of the cultivated Fig, FOLYGAMIA. 35 As the flowers of the Fig of every species are all closely shut up in their respective receptacles, it has been an interesting subject of inquiry to know how the seeds of the cultivated Fig, bearing only pistilla, could be fertilized. Two eminent botanists on the Con- tinent, Pontederax and Tournefort, have investigated this subject, and the result of their investigation is, that a very small kind of gnat, of a black colour, no where to be seen but about these trees, makes a punc- ture into the figs at the time of their flowering to de- posit their eggs, and in passing from one tree to another to perform this office they carry with them the dust of the antherae, and thus communicate the fertilizing principle to the stigma of the cultivated fig. In the Levant, where attention to the cultivation of the fig is of the utmost importance to the natives, as well for food as for traffic, the peasants, during the months of June and July, take these wild figs at the time their gnats are ready to break out of them, to their garden fig-trees 5 and every morning make an inspection, and transfer only such wild figs, which x Julius Pontedera was an Italian Botanist, born at Vicenza, in 1688. In the early part of his life he shewed a disposition- for those pursuits which have given celebrity to his name. He became professor of botany at Padua, and superintendant of the botanic garden of that University. He was also a member of the Academy of Inscriptions and Belles Lettres at Paris. He died in 1757. His principal work is his Compendium tabularum Botanicarum, in quo plantee 272 abeo in Italia nuper detect??- recensentur, Patavii, 171 8, in 4to» 3o POL VG AMI A. they call Orni, as are well conditioned for that pin- pose. Tonrnefort says, ( he was surprised at the pa- tience of the Greeks in busying themselves for the space of two months in carrying these gnats from tree to tree) but to satisfy his curiosity he was told that one of these fig-trees under their management usually produced between two and three hundred pounds of figs, while those of Provence seldom pro- duced more than twenty-five pounds.' In England figs are brought to maturity for the table without the assistance of the wild- fig, but the fruit must be distinguished from the seed, which alone is necessary to the reproduction of the plant. If the Pollen be wanting to fructify the seed, ex- perience has shewn in the instances I have before cited from experiments by Linnaeus himself, that the seed will not vegetate when sown; the fruit may nevertheless swell, and come to an appearance of per- fection, though it more commonly drops off before it ripens if the Pollen has been wanting. The fig-tree therefore with us cannot be propagated by seed, but by layers, suckers, or cuttings. Some species of summer figs in France and Italy, and also in Malta, ripen their fruits and seeds without the assistance of the wild fig ; it is, however, neces- sary to observe, that some species of the cultivated fig- tree have a few blossoms, or florets, with stamina placed above those that bear only pistilla within the same covering, and that in warm climates they are perfect, and perform their proper office ; but in cold POLYGAMIA. °t climates, as in England, and even in late seasQns in a warm climate, the stamina prove ineffectual, and the seed consequently unproductive. Of the cultivated fig there are thirty species or varieties cultivated in France, Spain, and Italy. The number of different species of Fig, of every kind, is not well ascertained: Martyn makes fifty six. The singular character of the inflorescence of this plant, the variety of the fructification in different spe- cies, and the union of the animal kingdom in some instances, as necessary to its reproduction, are pheno- mena in the highest degree curious and interesting.

THE PA UTS OF FRUCTIFICATION OBSCURE OR UNKNOWN. This Class has four natural Orders. ORDER I. PRICKLY POLYPODIUM. This fern is a na- filtges. live of most parts of .Europe, and grows in shady Fern*. places. Polypodium is the botanical term .for that Genus of plants commonly called Ferns, and of which there are enumerated no less than one hundred and thirty- seven species, the greater part of American growth. The investigation of this extensive Genus is attended with difficulty, from their general resemblance and habit, and from the obscurity of their specific cha- racters. This Class includes many genera, besides those which are called ferns, in the common acceptation of the word, as Adder's-tongue, Rough Horse-tail* Spleen-wort, &c. 40 CllYPTOGAMIA. EQUISETUM HYEMALE. Rough horse-tail. Of this plant there are seven species ; it is a native ot boggy woods and thickets in several parts of the king- dom. The root is perennial., and the stem is erect, which lasts throughout the winter ; hence the specific name hyemale: the fructification appears in summer. This plant has long been imported in a dried state from Holland, by the name of Dutch rush, to polish cabi- net work, ivory, and brass. The cuticle is extremely rough and hard, and is found to contain a large por- tion of flinty earth. In many parts of the East there has long been a medicine in high repute, called Tabasheer, obtained from a substance found in the hollow stem of the Bamboo cane, some of which was brought to Eng- land about twenty years ago. It underwent a chemical investigation, and proved to be an earthy substance, principally of a flinty nature ; this substance is also sometimes found in the Bamboo growing in England. In the hot-house of Dr. Pitcaim at Islington, subse- quent to this time, there was found in one of the joints of a Bamboo which grew there, on cutting it, a solid pebble withinside about the size of a pea. The pebble was of an irregular rounded form, of a dark brown or black colour. Internally it was red- dish brown, of a close dull texture, much like some martial siliceous stones. In one corner there were shining particles which appeared to be crystals, but too minute to be distinguished, even with a microscope. This substance was so hard as to cut glass. CRYPTOGAM I A. 4l The cuticle or exterior covering of straw has also a portion of flinty matter in its composition, from which circumstance, when burnt, it makes an exqui- sitely fine powder for giving the last polish to marble; a use to which it has been applied time immemorial, without the principle being philosophically known. In the great heat in the East Indies it is not un- common for large tracts of Reeds to be set on fire, in their motion, by the wind, which I conjecture must arise from the flinty surface of their leaves rubbing against each other in their agitation. In the works of Sir W. Jones is an elegant Sanscrit stanza, de- scribing the effect of Bamboo- canes often taking fire by the violence of their collision, and ad- dressed, under the allegory of a sandal-tree, as a virtuous man dwelling in a town inhabited by con- tending factions: it is thus translated: "Delight of the world, beloved ChandanaJ stay no longer in this forest, which is overspread with rigid pernicious Van- sas}z whose hearts are unsound; and who, being themselves confounded in the scorching stream of flames kindled by their mutual attrition, will consume, not their own families merely, but this whole wood."a These facts cannot avoid presenting to the mind the consideration of the boundless laws of nature; — while a simple vegetable secretes the most volatile and evanescent perfumes, it also secretes a substance which is an ingredient in the primeval mountains of the Globe. y The Hindu name of the Sandal-tree. z The Hindu name for this species of Bamboo. a Sir Wm, Jones, 4to, edit. Vol. ii p. 63. 42 CRYPTOGAM I A. ORDER 2. musci. MATTED HYPNUM. The shoots of this moss Mosses. are thickly interwoven, and form a close dark green mat on the decayed bark of trees in damp woods. The stalks on which the seed vessels are supported are short and slender, of a reddish colour, scarcely an inch high, and arising out of an oval bulb at the bot- tom ; one of them is given in the annexed plate mag- nified, that the parts may be more distinctly seen. The seed vessel, which is called a capsula, is urn- shaped, with a lid, which when taken off exhibits a margin fringed with numerous teeth. Upon the number of these teeth a celebrated naturalist13 has founded a new arrangement of this tribe of plants. By the aid of a microscope he has discovered that there is an invariable uniformity in the number of these teeth in the same species. That there should be such an absolute law in the ceconomy of nature in so minute a production, is infinitely interesting to the contempla- tive mind. Mosses are found in the hottest and coldest cli- mates. They are extremely tenacious of life ; and after being long dried, by moisture they easily recover their full vigour of vegetation: an experiment was made with success, by Haller, after they had been gathered fifty years. Those mosses which grow on barks of trees take much nourishment from them; b Hedwig. CRYPTOGAMIA. 43 Irence it is observed, that trees which are annually cleared from the moss grow nearly twice as fast. ORDER 3. REIN-DEER LICHEN. Upon this vegetable alg,e, the numerous herds of Rein-deer, the only riches of riags. the sequestered Laplander, are entirely dependant for their winter food. In that remote region it grows at least a foot high, covering the ground like snow. In England it is less luxuriant, seldom attaining to half that height. In grass fields and on gravel walks, after rain, it is not uncommon to find a gelatinous substance, vul- garly supposed to be the remains of a meteor, or fallen star. This is a vegetable production belonging to this natural Order Algae ; its botanical name is Tre- mella nostoc. Of this Order belongs the Genus Fuci, many of which have no root, but float on the surface of the water, and are entirely nourished by their leaves. The Byssus, another Genus of this Order, may be consi- dered as the last in the scale of vegetation, of which there are many species. They appear in form of threads, or a kind of meal, on rotten wood, the bark of trees, rocks, damp banks, and walls, especially of damp cellars. On stagnant waters there is often a 44 CRYPTOGAMIA. thin wide extended film on the surface, which is one species, and called green-paper Byssus. The various size and grandeur of vegetable produc- tions is not less remarkable than the different qua- lities of their fruits, or the endless variety and beauty of their flowers : while on the one hand we have the Byssus so minute as to require the investigation of the microscope, we have in the same vegetable kingdom a Pine-tree rising with a perpendicular stem to the height of more than two hundred feet, governed by the same laws and subject to the same principles of life. ORDER 4. &c. fungi. MOREL. This fungus is much esteemed as an Mushrooms, ingredient in sauces and soups, for which purpose it may be preserved dry lor many months, or even years. Those who employed themselves in gathering morels in Germany, observed that they grew most plentifully where wood had been burned} and to promote their propagation they were accustomed to set tire to the woods till that practice was prohibited by law. The ancient Hindus held the fungus in such detes tation, that Yam a, a legislator, supposed now to be the judge of departed spirits, declares, " Those who eat mushrooms, whether springing from the ground CRYPTOGAMIA. 45 or growing oh a tree,, fully equal in guilt to the slayers of Brahmens, and the most despicable of all deadly sinners."0 The Fungus, joined to the Morel, in the same plate, is die Agaricus semi-ova tus, introduced only to illustrate Linnaeus's seventh kind of Calyx. The dif- ferent species of Mushrooms, of which Agaricus is the botanical name, are so vaguely ascertained, that while Linnaeus makes only 2J species, Micheli makes &J4, Haller 134, and Withering 213. Formerly there was a great diversity of opinion, whether the Fungi were of an animal or a vegetable nature. Their animal scent, when burnt, and their growing and continuing healthy without light, in opposition to the general law of vegetables, inclined some to think that they could not be considered as plants: they are now, however, received as such, though their ceconomy and their mode of reproduc- tion are yet unknown. Fungi in general are supposed to be poisonous, but in Italy all kinds are ate with but little discrimi- nation, without producing any ill effects, which I suspect to be owing to the great quantity of oil the Italians use.in their cookery. One of the most extraordi- nary, as well as most esteemed of these productions are Truffles 5 Licoperdon tuber, which are tu- berous roots, without stem or fibre, of a dark brown c Sir Wm. Jones, 4 to. edit vol.2, p. 117. 46 CRYPTOGAM I A. colour, and of a uniform texture throughout; They grow altogether underground, at about the depth of nine inches, and are found by dogs, which are of a particular breed, and exclusively trained and practised in the south of France and Italy to hunt for them. I have now enumerated the twenty-four Linnaean Glasses, and all the Orders, so as to give a gene- ral view of the whole system. This book may be therefore considered as a Linnaean Dictionary, shewing the precise situation for any plant that can be found in any part of the world. When this ar- rangement is understood, then the families of plants, which are calied Genera, and their subdivisions into Species, may be studied with more facility, and the commencement of this study may be considered, in reality, as the commencement of the study of Botany. There is nothing more important in studying Botany, according to the Linnaean system, than to have a clear and distinct perception, that the know- ledge of classing plants by this system is of itself no part of Botany ; and this I am the more desirous to impress, because much error and confusion are pro- duced by considering the genera and species of plants as growing out of the Linnaean system of arrangement. The science of Botany, so called, is usually divided into three parts j 1st, the systematical arrangement of plants, with the denomination of their several kinds; 2dly, physiology, or the knowledge of the structure CRYPTOGAM 1 A. A7 and functions of their different parts ; 3dly, their eco-- nomical and medical properties. The first part of this division ought to be confined to the actual knowledge of the plants themselves, without any consideration of the artificial means by which that knowledge is to be obtained. The systematical arrangement of Linnaeus is only a contrivance to facilitate the knowledge of the vege- table world j to know where to place an individual plant, or where to look for it, without considering the relation or affinity it may have to any other in nature. As words are disposed in a dictionary, by an arrange- ment of their letters, so is the Linnaean system, and with as little reference to radical principles. Thus the letters b,.o, t, in a dictionary, are alphabetical, and by pursuing the same system, the v/ord botany is readily found- j yet the philologist, when he is thus in possession of it and has ascertained the situation of this combination of letters, he yet knows nothing about what relation it bears to other words, whether it indicates a thing or an action, or any quality or modifi? cation of either : this knowledge must be the result of a separate inquiry. In like manner the Botanist counts the stamina of a plant, which, for example, may be five, with one pistillum in the midst, and immediately he finds it in the Ciass and Order Pentandria mono- gynia. From this information alone, he knows no- thing about the plant itself; from these signs or cha- racters he cannot tell whether it be a Rhamnus> 48 CRYPTOGAM I A. an Azalea, or a Night-shade ; whether it be a tree two hundred feet high, or a primrose at his feet jd but, by combining this knowledge with an exami- nation of all the most obvious appearances of every part of the flower, or according to the Lin- naean language, the seven parts of fructification, he identifies it; and when with a more compre- hensive view he can assign to it a place in the oeconomy of nature ; agreeable to its configuration, appearance, and habit, he may be said to be acquainted with this first division of his subject, so far as con- cerns the particular Genus which is the subject of investigation. The genera and species of plants are established in nature, the knowledge of which can alone be con- sidered as worthy of constituting that department of botanical information which comes under the head of Nomenclature, if this department can be said' to have any pretension to the dignity of a science. A familiar notion of a Geyius may be readily ap- prehended by comparing it to a great family, as the S In this artificial arrangement of Linnaeus, in some in- stances, species are even separated from their Genus. The Sweet- scented Vernal-grass, Rice, and Zizania, are ail separated from each other and from the tribe of grasses to which they belong. Some of the Rushes are separated from the rest. The two common Elms of the country are in two different Classes, and the five species of Rhubarb, according to their natural affinity, ought to be united with the Rumex, or common dock. CRYPTOGAMIA. *9 Howards, and the species, to the Houses of Norfolk, Suffolk, Carlisle, and Effingham. Although at first view the structure and appear- ance of a plant is strikingly different from an animal, yet from the examples in the preceding pages, there are some instances in which their character resembles each other so strongly, that it has been found more difficult than it would be at first imagined, to make an accurate distinction between them. The power of changing place in animals is an obvious character which serves to make a good general distinction be- tween these two kingdoms of nature, but on close examination it will be found that there are many ani- mals that have no such power ; and there are vegeta- bles that have no root, and are constantly changing place. Spontaneous motion and irritability are also common to the vegetable kingdom, as I have already- shewn . That definition therefore of a plant which has been thought to be the least objectionable, is, that it is an organized body, nourished by matter des- titute of any living principle, while animals live upon what possesses, or has possessed life ; and the conside- ration of this law is the more interesting, as it would seem to shew one grand scheme in the universe, in which the Fossil, the Vegetable, and the Animal kingdoms are rendered alike subservient to each other, and mutually perish to restore new life, to perpetuate the revolving system of Nature.

The different Genera of British plants of which there are figures in this work, are in the following pages described by their characters founded in nature, and agreeably to the principles of Linnaeus, taken from the seven parts of fructification. The examples comprehend all the Classes and Or- ders according to theLinnaean system; to the characters of which I confined myself entirely in the previous pages, that the system might be clearly and fully understood, and that the facts on which the arrangement depends might not be confounded with the more general eco- nomy of nature on which Generic and Specific cha- racters are established. When these volumes are read, and the parts of fruc- tification attended to which are defined and demon- strated in various examples, the technical language used in generic descriptions will be understood with- out difficulty 3 and by the help cf the figure and an examination of the plant itself this work will put the learner in possession of the knowledge of one hundred ADVERTISEMENTS. and thirty- two Genera of plants, of which the greater number are natives of Great Britain. This will be a good foundation for the Study of Botany, as a science, and afterwards, other works, more comprehensive, may be studied with advantage. HIPPURIS.
