' Botany teaches the knowledge of Plants, either, 1, with respect to their characters and distinctions; 2, their structure and the uses of their several parts; or 3, their various qualities with regard to mankind, and the brute creation. 2. The 1st is called Systematical, the 2d Physiolo- gical, and the 3d Economical Botany. 3. Systematical Botany is founded on a knowledge of the external structure of plants, and the different forms under which their various parts and organs appear. By this we are enabled to distinguish one species of plant from another, as well as to assem- ble or arrange them in families, orders or classes. 2 SUBJECT. 4. Physiological Botany, besides a knowledge of the external forms of the vegetable body, requires an acquaintance with its internal structure, and the dif- ferent substances therein produced and contained, termed Secretions, with the purposes which such se- cretions answer. 5. Economical Botany is either empirical or philo- sophical. The former originates in the experience and practical observation of mankind, from one age to another : the tfijter is deduced from a consideration of certain characters in vegetables ; either indicating peculiar properties ; or pointing out affinities, more or less remote, by which certain known qualities in some plants, are presumed to exist in others. 6. Before a.m Knowledge of Systematical Botany (3), or the Classification of Plants, can be understood, it is necessary to be acquainted with the various parts of which the Vegetable body consists. These" are the Root, Stem, Stalks, Buds, Leaves, Appendages, Flower and Fruit. 3 CHAPTER IT. DESCENDING PART OF A PLANT. ROOT. 7. Radix, the Root, serves to fix the plant, and to imbibe nourishment for its support. It usually consists of a Caudex, or Body, the top of which is called the Crown ; and Radiculte, Fibres ; the latter being always present, and constituting the real, . or efficient, root. Radicula, the Radicle, or Primary Fibre, is the point of the Embryo (62 : 1) first pro- truded in incipient germination. 8. Roots are distinguished into 7 kinds. i. Radix fibrosa, a Fibrous Root, composed of fibres only, as in many annual plants, and most grasses. fi. R. repens, a Creeping Root, as in Mint and Couch-grass. s. R.fusiformis, a Tap Root, like the Carrot and Radish. R. pramorsa, an Abrupt Root, as Scabiosa sue- cisa. i- R. tuberosa, a Tuberous or Knobbed Root, as the Potatoe, Paeony, and Orchis. a- R. bulbosa, a Bulbous Root, either solid, like that of the Crocus ; lamellated, like Onions ; or scaly, like the White Lily. B 2 4 DESCENDING PART OF A PLANT. ROOT. r. R, articulata or granulata, a Jointed or Gra- I nulated Root, like Wood Sorrel, and White Saxifrage. Q, Roots differ in duration, being either annual, bien- nial, or perennial. Fibrous and Tap Roots are 1 1 frequently annual ; some Tap Roots are biennial ; 1 1 Creeping, Abrupt, Tuberous, Bulbous, and Jointed I Roots are always perennial, as are some Fibrous 1 and a few Tap Roots. 10. Annual Roots produce the herbage, flowers, and seeds within the compass of one season, after which they entirely die ; Biennial ones produce herbage only the first summer, flowers and seeds the next, after which they also die ; Perennial 'Roots bear herbage and flowers through several successive years, to an indeterminate extent, and moreover increase, or form offsets, either spontaneously, or with the assistance of art. 1 1. The Root is the first part produced by the Seed, when beginning to vegetate in the earth. It is na- turally directed downwards, extending itself at the extremity, and forming fresh fibres every year, such (7) being an essential part of every kind of root, the vegetation of which, and of the plant it bears, going on only while the fibres continue to grow, and to imbibe nourishment. 5 CHAPTER III. ASCENDING PART. HERBAGE. 12. Caulis, the Stem, properly so called, serves to elevate the leaves and flowers above the ground, as m trees, shrubs, and many herbaceous plants, but is not essential to all. 13. The Stem is either annual, or perennial ; simple, or branched; leafy, scaly, or naked; solid, or hol- low ; upright, twining, climbing, procumbent, or •creeping ; straight, spreading, or zigzag ; round, an- gular, winged, or compressed ; smooth, downy, hairy, bristly, or prickly ; even, striated, furrowed, or warty. 14. A branched Stem (13) is either irregularly sub- divided, or 1. Caulis dichotomies, a Forked Stem, having a flower at each fork or subdivision. 2. alter nc ramosus, alternately branched, the branches being solitary, and variously directed. 3- opposite ramosus, oppositely branched, when two branches stand together, spreading in oppo site directions. 4- verticilla/us,whoY\ed, many branches spread- ing in every direction from one point. 5- '" 1 " determinate ramosus, abruptly branched, 6 ASCENDING PART. HERBAGE. when each branch, after terminating in flowers, sendsout numerous shoots from near its extremity. 6. Caulis articulatus, jointed, as in Samphire, and Cactus. 7. distichus, two-ranked, the branches spread- ing in two opposite directions. 8. brachiatus, four-ranked, when they spread in four directions. 9. volubilis, twining, turns spirally ; to the right in some plants, to the left in others, inva- riably. 15. Plants without a stem are termed acaules, stem- less, and the leaves are then necessarily radical, springing directly from the root. 16. Culmus, a Culm or Straw, the peculiar stem of Grasses, is leafy, cylindrical, well known, though not easily denned, nor is this term very necessary. See fig. J 39, 141. 1. Culmus enodis, simple, or without joints, as in Juncus effusus, &c. 2. articulatus, jointed, as in Oats, and most Grasses. 3. ■ geniculatus, bent, at one or more joints, like the knee or elbow. The surface is either smooth, rough, downy or bury, never prickly ; often striated or furrowed. 17. Scapus, a Stalk, springs from the root, and bears the flowers and fruit, but no leaves. 18. The Scapus is either simple or branched ; single- ASCENDING PART. HERBAGE. 7 or tnany-flovvered ; erect or procumbent ; straight, wavy, or spiral, as in Cyclamen and Valisneria after flowering. 19. Pedunculus, a Flower-stalk, springs from some part of the stem, and bears the flowers and fruit ; if radical, it is a Scapus. 20. A Flower-stalk is either terminal or lateral : if lateral, it is either axillary, or oppositifolius (oppo- site to each solitary leaf), or interpetiolaris (between the bases of 2 foot-stalks, laterally), or internodis (from the part of a branch between 2 joints, or leaves). It is termed gemmaceus, when proceeding from the same bud with the leaves. It is simple or compound; solitary or aggregate ; erect, spreading, drooping or pendulous. 21. Flowers destitute of a stalk are termed sessiles, sessile. 22. Pedicellus, a partial Flower-stalk, is the ultimate division of a Pedunculus (19). It is also used for the Fruit-stalk, elevating the Germen and Fruit in Mosses, and some other plants. 23. Petiolus, a Foot-stalk, is the stalk of a Leaf, very rarely connected with, or bearing, the flower-stalks. This part, usually channelled along the upper side, is either simple, as in all simple, and some com- pound leaves ; or compound, cither once, twice, or more ; and sometimes, as in the Pea and Vetch tribe, ends in tendrils (47 : 5). 8 ASCENDING PART. HERBAGE. 24. Frons, a Frond, is a stem and leaf in one, bearing the fructification, as in Ferns, where the flowers and seeds grow mostly on the back ; or the Lichen and Sea-weed tribes, where they are more or less im- bedded in the leafy or crusty substance of the plant. This term is only used in the class Cryptogamia, whose flowers are anomalous, or ill understood. In spiked Ferns the frond is partially transformed into fructification. 25. Stipes, a Stipe, is the Stem of a Frond (24), as in Ferns, where it is commonly scaly; or the stalk of a Fimgus, (Mushroom) fig. 129. 26\ Gemma, a Bud, contains the rudiments of a plant, or part of a plant, latent, and wrapt up in scales, till the season is fit for their expansion. Vernatio is used by Linnaeus to express the disposition or folding of the scales. 27. Buds chiefly belong to trees of cold or temperate climates, and powerfully resist cold till they begin to open. 28. The Buds of herbaceous plants (10) are radical. Bulbs are the buds of a certain tribe of herbs (8), their scales being no other than subterraneous leaves, as is evident in Lilium. 29. Some buds contain only leaves, others only flowers (20), others both. 30. Folium, a Leaf, a very general, but not universal organ, is of an expanded form, usually green, pre- ASCENDING PART. HERBAGE. 9 senting its upper surface to the light, the under commonly differing in hue, and in kind or degree of roughness. The inside is pulpy and vascular. 31. Leaves receive the sap from the wood by one set of vessels, and expose it to the action of air, light and heat by their upper surface, while what is su- perfluous passes off by the under. The Sap thus changed assumes peculiar flavours, odours, and other qualities, and is sent by another set of vessels into the bark, to which it adds a new layer every year internally, and another layer to the external part of the wood. Hence the concentric circles in trees, the number of which shows their age, and the breadth of each circle, the abundance and vigour of the foliage which formed it. 32. Leaves are wanting in some tribes of plants, wh 3se stems are usually very succulent ; such as Salicornia, Ciiscuta, Stapclia. 33. The situation of Leaves (30) is either at the root, or on the stem or branches ; alternate, scattered, opposite, crowded, whorled (3, 4, or more in a whorl), or tufted. 34. Their position is either close-pressed to the stem, imbricated, erect, spreading, horizontal, reclinate, recurved, or inflexed ; oblique (or twisted) or re- versed (the upper surface turned downward) ; de- pressed, floating, or immersed; two-ranked (spread- ing two ways 14:7); decussated (crossing each other in pairs) ; or unilateral (leaning all to one side). 10 ASCENDING PART. HERBAGE. 35. Their insertion is either sessile or stalked ; peltate, clasping, connate, perfoliate, sheathing, equitant, or decurrent. 36'. Then form is simple, or compound in various de- grees ; undivided, or lobed ; their outline very va- rious in different plants; sometimes different on the same individual. The lower leaves of water plants, the upper of mountain ones, have commonly the greatest tendency to be much divided. For their particular forms see Introduction to Botany. 37. Foliola, Leaflets, are the partial leaves, which, con- nected by one common, simple or branched, foot- stalk (23), make a compound leaf. 38. The margin of Leaves or Leaflets is either entire, wavy, serrated, jagged, toothed or notched, in a sim- ple or compound manner ; naked, fringed, spinous,, cartilaginous, glandular ; flat, revolute (rolled back- ward), or involute (the reverse). 39. Their surface is smooth, naked, glaucous, downy,, hairy, woolly, warty, glandular, or prickly ; even, rugged, or blistery ; veiny, ribbed, or veinless ; co- loured, variegated, opaque, or polished. Their ribs and veins contain the principal sap-vessels. 40. Some Leaves are fleshy, cylindrical, semieylin- drical, awlshaped, tumid, channelled, keeled, two- edged, hatchet-shaped, solid, or hollow. 4 1 . Others are membranous, leathery, rigid, or almost woody* 42. The tcrminalion ol Leaves is either obtuse, acute, ASCENDING PART. HERBAGE. I 1 pointed, obtuse with a point, spinous-pointed, or cirrhose as in Gloriosa; abrupt, jagged-pointed, re- fuse, or emarginate. 43. With respect to division (36), Simple Leaves are either cloven, lobed, sinuated, deeply divided, laci- niated, or cut; palmate, pinnatifid, pectinate, un- equal (as in Begonia), lyrate, runcinate, fiddle- shaped, hastate, arrow-shaped. 44. Compound Leaves are either jointed, fingered, binate, (or conjugate,) ternate, quinate, pinnate with or without an odd leaflet, whorled, or auricled ; they are simply, doubly, thrice, or more, compound ; pedate, twice paired, twice ternate, or doubly pin- nate, &c. 45. In duration, Leaves are either deciduous or ever- green ; the former lasting but one summer ; the latter two or more, though a fresh crop is pro- duced every year, so that the tree or shrub is never stripped. 46. Some Leaves or Leaflets are continuous, never se- parable from the stem or footstalk, as in Ruscus, the natural order of Musci (Mosses), and the genus Jungermannia. 47. Fulcra, Appendages, belong to the herbage of a plant, and are of 7 kinds. i. Stipula, the Stipula, a leafy appendage to the proper Leaves (30), or their Footstalks (23); usually in pairs, at the base of the latter, either united thereto, or distinct; sometimes simple and ASCENDING PART. HERBAGE. intrafoliaceous (withinside of the leaf), as in Grasses, fig. 141, and Polygonum, as well as the tribe called Rubiacece, fig. 198, 199- In some of the latter they are divided, or compound. Some Stipulas are soon deciduous, others permanent as long as the Leaves. This organ is by no means universal, even in the same genus, as Cist us ; nor constant in the same species, as SalU\ Bractea, the Floral Leaf, a leafy appendage to the Flower, or its Stalk (17, 19), is often co- loured; either deciduous, or as permanent as the Flower-stalk, to which it is sometimes firmly attached. Sphia, a Thorn, originates in the wood itself, and by culture in rich soil, disappears, becoming a branch. Footstalks (23) sometimes harden into spines ; as do Stipulas (47 : 1) in Xanthium ; and Flower-stalks (19) in Pisonia. Aculeus, a Prickle, arises from the bark only, as in Roses, and does not disappear by culture. Cirrus, a Tendril, a true fulcrum or support, is either axillary, or terminates a Leaf (42) or a Footstalk (23) or even a Flower-stalk (19), serving to sustain weak stems upon others. Tendrils, at first straight, soon turn spirally, and in some in- stances turn again, in the contrary direction. They are simple or branched ; their extremities often dilated and adhesive. The fibrous supports of Ivy arc peculiar Tendrils, not Roots. Foot- ASCENDING PART. HERBAGE. 13 stalks (23) sometimes perform the office of Ten- drils, as in Clematis cirrosa. Glandula, a Gland, a small tumour, discharging a fluid, either resinous, oily, or saccharine. Pilus, a Hair, including all the various hairy, woolly, bristly, or even tubercular, clothing (or pubescence) of plants. Such hairs are either sim- ple, hooked, forked, starry, or branched, gene- rally jointed and tubular ; either harmless, pun- gent, or stinging ; erect, close-pressed, or derlex- ed ; flexible, rigid, or brittle and deciduous. They protect plants against heat and cold, or the attacks of animals. They are very often excre- tory ducts, discharging more or less of an oily, glutinous, odoriferous, or colouring fluid. 14 CHAPTER IV. INFLORESCENCE. 48. Infl ores centia, the Inflorescence or Mode of Flowering, expresses the manner in which Flowers are situated upon a plant. It is essential, though of temporary duration, and comes under the following denominations. 1. Verticillus, a Whorl, when the Flowers form a ring round the stem, though perhaps inserted on two of its opposite sides, or even on one onl^. 2. Racemus, a Cluster, consists of scattered Flowers, each on its own proper stalk (22), connected by one common stalk (20), all nearly in perfection together. A Cluster is sometimes compound ; or aggregate like Actcea racemosa. 3. Spica, a Spike, is composed of many Flowers, sessile, or nearly so (21), on one common stalk, sometimes branched, generally very erect; the flowers opening in succession ; sometimes unila- teral (34). Spicula, a Spikelet, is the inflores- cence of such Grasses, as have many florets in one calyx. 4. Corymhus, a Corymb, a kind of Cluster (48 :2), whose partial stalks are gradually longer down- wards, so that the flowers they bear are nearly INFLORESCENCE. 15 on a level. After flowering this usually becomes a perfect Racemus. Fasciculus, a Tuft, is composed of numerous level Flowers, on little stalks, variously connect- ed and subdivided. Capitulum, a Head, consists of sessile Flowers, crowded together into a globular figure, the cen- tral, or terminal ones generally opening first. Umbella, an Umbel, is formed of several Stalks, radiating from a centre, and nearly equal in length, so as to compose a level, or convex, rarely concave, surface of flowers. It is, in true Umbelliferous plants, rarely simple, generally compound, each Stalk, or Ray, bearing a Par- tial Umbel, Umbelhda. The Umbel in such plants is termed Jlosculous, when the flowers are all nearly equal and uniform ; radiant, when the marginal ones are more or less irregular and un- equal. In other orders of plants the Umbel, if present, is generally simple, but less perfect as to the insertion of its stalks ; witness the orders of Apocinece and Asclepiade FRUCTIFICATION, Oli FLOWER AND FRUIT. B. composite, a Compound Berry, is composed of several single-seeded grains. B. cortkata, a Thick-skinned Berry, has a firm rind, like the Orange, the Gourd, &c. B. spuria, a Spurious Berry, originates either in the Calyx becoming pulpy, like the Mulberry, and perhaps the Fig; the Corolla, as in Commclina Zanonia ; the scales of a Catkin (53 : 3), as in Jimiperus ; or the Receptacle (63), as in the Strawberry, and perhaps the Yew. 0*7. Strobilus, a Cone, a Catkin (53:3) enlarged and hardened, lodging the Seeds * either naked be- tween its scales ; or in a sort of Capsule, con- nected with the base of each, more rarely stalked and distinct, as in Willows. 6'2. Sem'uia, the Seeds, to the perfecting of which all the other organs are subservient. Each Seed con- sists of several parts. i. Embryo, the. Embryo or Germ (called Corcu- lum by Linnaeus) is the most essential of all, no seed being capable of vegetating if this part be defective, as happens chiefly for want of the assist- ance of the Pollen (58), if the latter be spoiled by wet, or otherwise hindered ; though the Seed may outwardly appear sound. This part sends out the Root (7) downwards, and the Pliumda, or bud of the Stem or Herbage (12), upwards. a. Cotyledoncs, Cotyledons or Seed-lobes, closely attached to the Embryo, commonly two, rarely FRUCTIFICATION", Oil FLOWER AND FRUIT. 25 more, in some tribes altogether wanting. They either ascend out of the ground, and perform for a while the office of Leaves (31), or remain bu- ried, till they gradually decay, at Albumen, the White, a farinaceous, fleshy, horny, or almost stony, substance, destined to nourish the Embryo during the first stage of vegetation, till the Root can perform its office (7). The Al- bumen forms a separate body in Grasses, Palms, the Liliaceous tribe, and other monocotyledonous Plants, properly so called, though this substance itself, which makes up the chief bulk of such Seeds, is commonly taken for their Cotyledon. Becoming fluid, it is soon totally absorbed by the sprouting Embryo of these plants. In many dicotyledonous Plants the Albumen is likewise distinct from the Cotyledons, as the Nutmeg, where it is large and curiously eroded or sinuated ; Mirabilis, Polygonum, and Rume.v, where it is mealy and shapeless, inclosing the Embryo and Cotyledons ; and some few Leguminous Plants (61 : 3), though in most of this last tribe it' does not constitute a separate part, any more than in the Gourd family, the Walnut, and many others. In such, the albuminous matter is lodged in the substance of their Cotyledons; for it must be pre- sent in some mode or other, to supply the first food of the germinating Embryo. Ga;rtner distin- guishes an organ by the name of VkcUm,ov Yolk, l26 FRUCTIFICATION, OK FLOWER AND FRUIT. in Seeds, which appears to mc always either a pair of subterraneous Cotyledons, or a part of the Em- bryo ; see Trans, of Linn. Soc. v. ix. 204. 4. Testa, the Skin, either simple, or lined with a finer film, Mcmbrana, contains, and gives a shape to, the foregoing parts, and fan vegetation bursts irregularly. A pulpy Seed, Semen baccatum, is furnished with pulp between the Membrana and the outer Skin, as in Jasminum*. Hilum, the Scar, or point of attachment, at the base of every Seed, where all the internal parts meet, and through which they are nourished while growing. Accessory, not essential, parts of a Seed are : 6. Strophiolum, the Crest, an occasional appendage to the Scar, of a glandular appearance, as in Chelidonium, and some Leguminous genera, Ulex, Spartium, fyc. 7. Pellicula, the Pellicle, a thin close membrane ; a downy covering ; or a glutinous substance, not perceptible till the Seed is moistened, as in Sal- via verbenaca. * M. Richard, who unnecessarily, 1 think, invents the term Epi- spcrm for the Testa of Ga;rtncr, asserts this covering to be always sim- ple, though he allows it to be formed of two membranes, with an in- termediate vascular parenchyma, or pulp. Any person who examines the kernel of an Apple will surely, in every- stage of its growth, find a dou- ble Testa, the outermost firmly coriaceous, the innermost membranous ; nor are numerous instances, of the same kind, wanting, where the external Testa can by no means be taken for any thing clhe. FRUCTIFICATION, Oil FLOWER AND FRUIT. 27 8. Arillus, the Tunic, a complete or partial co- vering, attached to the base only, more or less loose, or inflated, as in Urania, tig. 155, Euony- inus, and the Mace of the Nutmeg. In O.valis this part is elastic ; yet perhaps a more genuine Aril- lus than in the true Rutacece, or the Euphorbice. See Jussieu's 81st and 96th orders. o. Pappus, the Seed-down, a feathery, hairy, bristly, or membranous tuft, or crown, at the summit of a Seed, rarely at its base, most important in the Compound Flowers. io.

Receptaculum, the Receptacle, the common base, or point of connexion, where all the parts of a Flower meet : as also the place of insertion of the Seeds (62) more particularly. The Receptacle of a Flower is the disk, or space between the Sta- mens (58) and Pistil (59) ; especially if the Ger- men be inferior. In Compound Flowers (68) the Common Receptacle, being either naked, hairy, scaly, or cellular, affords generic distinctions. 38 FRUCTIFICATION, OR FLOWER AXI) FRUIT; 64. Flos completus, a Complete Flower, is furnished with both Calyx (53) and Corolla (54) ; without j the former, it is nudus, naked ; without the latter, apetalas, ape talons. 65. With respect tk> the essential organs of fructifica- |i tion ; Flos perfectus, a Perfect, or United, Flower, bears Stamens (58) and Pistils (59) ift the same individual. Flores separate Separated Flowers, have Stamens- in one, Pistils in another. This se- paration is absolute in Monoecious Flowers, where both kinds grow on the same plant, and in Dioeci- ous ones, where they grow on two distinct plants, of the same species ; but in Polygamous ones there are some Perfect Flowers, as well as Separated ones, on the same plant, or on different ones. Neuter or Abortive Flowers have both organ's de- fective. 66. Flos sterilis, a Barren Flower, has Stamens only {65), and can consequently produce no Fruit or Seed. 67. Flos fei'tilis, a Fertile Flower, has Pistils only (65), but produces no Seed without the assistance of the Barren one (66). 68. Flos compositus, a Compound Flower, consists of numerous Flosculiy Florets, or partial flowers, in a Common Calyx, the Anthers (58) of each of such florets being united into a cylinder. The Corolla (54) of each floret is monopclalous (56), and cither tubulosa, tubular, or ligrdala, strap-shaped, flat. FRUCTIFICATION, OR FLOWER AND FRUIT. 29 69. Flos aggregatus, an Aggregate Flower, consists of several Flowers, or Florets (68), with distinct Anthers, collected into one Common Calyx, as in Scabiosa, and all Amentaceous Flowers (53 : 3), as also most Grasses, and according to Linnaeus, um- bellate and even cymose flowers (48), which last we can scarcely admit, they being rather modes of Irflorescence. 70. Compound Flowers (68), as well as Aggregate ones (69), are eitherjlosculosi, flosculous, or radiati, radiant, as already explained under Umbella (48 : 7). 71. Cryptogamic Plants, are those whose Flowers are either totally unknown, like Ferns (77) ; or not constructed according to the analogy of Plants in general, as above described, like Mosses (77) : so that they cannot be referred to Classes and Orders by their Stamens and Pistils, as hereafter to be ex- plained. Phaenogamic Plants, on the contrary, have evident Flowers, constructed according to the above- described principles. 30 CHAPTER VI. PRINCIPLES OF CLASSIFICATION. 72. Ever since Botany has assumed the form of a Science, Botanists have agreed that every principle of Classification must be deduced from the parts of fructification (52). 73. All botanists are also agreed, in distinguishing the Vegetable'Kingdom into Classes, Orders, Genera, and Species. 74. Species are generally acknowledged to be per- manently distinct, though liable to Varieties, and occasionally to the production of intermediate Spe- cies, by the access of the Pollen (58) of one, to the Stigma (59) of another ; but such appear to have only a transient duration. 75. Genera, as far as they are rightly determined, are considered by Linnaeus, and his scholars, as no less natural than Species (73), but this opinion is re- jected by many botanists, especially of the French school, even while they contend for the existence of natural Orders. 76. Classes and Orders, which are assemblages of Genera (75), are either natural or artificial. 77. Natural Classes and Orders (76) are such as ap- P 1MNCIP LKS 0 6 C I, A SSI K I C A T [OX. 31 pear indicated by Nature herself. Some are very evident, as Grasses, Umbelliferous Plants, Com- pound Flowers, the Orchis tribe, Palms, Ferns, and Mosses. Others are more obscure, and many plants cannot yet be referred to any such Orders or Classes. 78. Artificial ones (76) are contrived for human con- venience, to assist the memory, and to promote the determination and discrimination of plants. Such constitute the Linnnean system, founded on the Stamens and Pistils (58, 59); those of Tournefort and Rivinus upon the Corolla (54) ; and those of Ray, and several other authors, upon the Fruit (61) and Seed (62). 79. Linnaeus first pointed out the distinction betwixt a Natural and an Artificial System ; but Bernard de Jussieu and his nephew Antoine Laurent de Jus- sieu, first formed and published a Natural System, reduced to a regular form upon scientific principles. SO. Linnaeus contended that human science was not yet competent to give definitions, or technical cha- racters, of Natural Classifications. 81. Adanson indeed undertook this, and A. L. de Jussieu has founded his System, published at Paris in 1789, upon such characters; which though in- complete, and liable to various exceptions, is of great use as a key to a Natural Arrangement (79). In proportion however as it serves this purpose, and is dependent on definitions, it becomes in many 32 PRINCIPLES OF CLASSIFICATION. instances artificial, breaking, natural affinities, or producing unnatural ones ; defects inevitable in all such undertakings, from our imperfect acquaintance with the Vegetable productions of the whole globe. 82. In the Systematic arrangement of Plants, whether artificial or natural, some botanists consider one part of the fructification (49), others another part, more important than the rest. 83. As far as Artificial Classification (78) is concern- ed, this is little more than a matter of opinion ; but the Linnaean System, as being founded on the num- ber, situation, and proportion, of the Stamens and Pistils (5S, 59), organs which must exist in some shape or other, has been found the most commo- dious, and has put aside every other. 84. Such a mode of arrangement answers the purpose . of a dictionary, to find out plants by their charac- ters, as words by their orthography. 35. There is scarcely a principle which can be assumed as universal, or without exception, in Natural Classification. Number, in the parts or divisions of each organ, proves often fallacious ; Insertion, or the mode of connexion of the several organs,, and their comparative situation, with regard to each other, is found far less exceptionable ; Structure, or the different forms of the same organ, in different instances, is of very great moment. 86. Linnams and Jussieu concur in considering as of primary importance the Structure (85) of the Em- PRINCIPLES OF CLASSIFICATION. 33 bryo (62 : 1), and the Cotyledons (62 : 2) ; and the former has declared that the number of the Coty- ledons appeared to him to atford a sure basis, or primary source of discrimination for a Natural Sy- stem. He soon found what he thought an excep- tion in Nympluza, but was deceived in that instance. The above principle, doubtless, is good, but some correction of the commonly received ideas and terms is become necessary, since the structure and eco- nomy of Seeds have been more closely investigated. S7. Gaertner and Jussieu have shown that the Albu- men (62 : 3) advantageously serves in the natural arrangement and discrimination of Plants. This however is liable to as many exceptions, in the de- tail, as almost any other source of characters. 88. Plants with a simpk undivided Embryo (62 : 1) are termed Monocotyledones, or monocotyledonous ; the upper end of that organ being presumed to per- form the necessary functions of a Cotyledon, with respect to air, in the earliest stage of germination. Hence the term in question may properly be re- tained, though originally meant to apply to the se- parate, and usually copious, Albumen of such plants, visible in Corn, Palms, &c. 89. Plants whose Embryo divides at the top into two parts or lobes, which are the Cotyledons (62 : 2), are named Dicotyledones, or dicotyledonous. In some jew instances, as the Fir tribe, there are numerous Cotyledons ; but such plants differ in no particular I> 34 PRINCIPLES OP CLASSIFICATION. of their economy from those which have onlv two, and are therefore comprehended under the saint; denomination. i)0. Some Plants, especially those with anomalous or obscure fructification, have been judged Acotylc- doncs, or destitute of a Cotyledon. The idea and the term are partly founded in error. Of some which have been thus considered, nothing is cor- rectly known of the structure or germination of their Seeds, as Fuftgi, and Submersed Alga (Fuci, Con- ferva, dec), nor has much been ascertained relative to the Hepatica, or the Lichenes. We know that their Embryo is of the most simple kind, without appearance of Cotyledons or Albumen, so that they appear to differ from the Monocotyledones (88) chiefly in the want of a separate Albumen, that nu- tritious matter being probably lodged in the sub- stance of the Embryo, as it is in the Cotyledons of many of the Dicotyledones (62 : 3). But this is conjectural. Musci, Mosses, (77) properly consi- dered, appear to agree with Hepatica, to which they are otherwise very closely allied, in having a simple Embryo, without either separate Cotyledons or Albumen. But they subsequently produce a pe- culiar accessory organ, consisting of several branch- ed and jointed fibres, springing upwards or laterally, from the crown of the Root (7), and very distinct from its radicles. These fibres arc taken by Iled- wig for Cotyledons, which from their late forma- PRINCIPLES OF CLASSIFICATION". 35 tion they can scarcely be ; and we may rather con- sider their nature and use as undetermined. They perhaps differ little from the woolliness so common on the Stem of these plants in an advanced state, Filices, Ferns, (77) differ somewhat from Mosses in having a membranous and flat expansion of the Embryo, sometimes fixed by the centre. Still this part may be considered as simple, and what are subsequently produced, howevershapeless,aredoubt- less of the nature of Leaves, or Fronds (24), which in these plants are of a more Proteus-like, or mu- table, figure than in any others. Ferns want the above-mentioned jointed fibres of Mosses in germi- nation. 91. From what has been said (90) it appears that the old appellation of Acotyledones may commodiously remain with Cryptogamic vegetables in general (71), though the form of their Embryo, and mode of germination, are, in some of this tribe, only pre- sumed from analogy. Those with which we are acquainted are certainly destitute of any Cotyledon, and of any separate Albumen. 92. Jussieu however ranks under this denomination an Order termed Naiades, consisting of aquatic plants, with perfect, not cryptogamic, fructifica- tion. Of many of these his knowledge, respecting the point in question, was incomplete, and he has candidly owned his difficulties. Most of the plants, on being better understood, prove either dicotyle- J) 2 JO PRINCIPLES OF CLASSIFICATION. donous, or monocotyledonous, and naturally range with their allies in other parts of the System. 93. Mr. Robert Brown, who has greatly illustrated the System of Jussieu, and the Natural Orders of Plants, has shown that in the Monocotyhdones the number three, and its compounds, prevail in the several parts of fructification, insomuch that in Orders furnished with only one evident and perfect Stamen, there are rudiments of 2 others. So in the Orchis tribe, as I understand it at least, while there are 3 Calyx-leaves, the 2 Petals (55) and the solitary Nectary (57) make up the same number in the Corolla, fig. 70, 77. 94. In Dicotyledoncs the number five no less remark- ably prevails, throughout the great bulk of the Ve- getable kingdom, as is evident on the slightest in- spection. 95. Jussieu and his followers attribute a Calyx only, no Corolla, to Monocotyledonous plants, however conspicuous, coloured, elaborate, or compound the integuments of the Flower (53, 5-1) may be. This proves most flagrantly paradoxical in the natural order of Scilam'uiccc, fig. 1 ; and it is evidently ab- surd that we must wait to name the obvious parts of a flower, till we have investigated the structure or germination of its seed. We allow indeed that the difficulty is lessened, though not infallibly re- moved, by Mr. Brown's rule respecting numbers (93, 94). PRINCIPLES or CLASSIFICATION 37 gS. The insertion of the parts of a Flower, or in other words, the situation of the Germen (59), whether inferior or superior, with regard to the rest, next takes the lead in importance in Jussieu's system ; and in the Dicoti/ledo??es the absence or presence, the number or divisions, of the Petals (55), afford even more leading, if not important, distinctions. 97. The terms used by Jussieu to indicate the above different insertions apply to the Stamens (58). Thus, Stamina hypogyna are inferior, inserted beneath the Germen, fig. 14 and 16. Stamina epigyna are inserted above it, fig. 11. Stamina per igyna are inserted into the integuments of the Flower, which, if simple, is always de- nominated a Calyx (95) by this author, fig. 13 ; if otherwise, the Stamens are borne either by the Calyx, fig. 19, or the Corolla, fig. 8, 9. But such insertion never takes a lead in his system, unless it be into, what he at least considers as, a Calyx. The above terms apply likewise to the Corolla. 98. Characters derived from proportion, do not enter at all into the principles of Jussieu's classification, nor scarcely those founded on number, except so far as whether that of the Stamens or Pistils be de- finite or indefinite. 9.9. This System is confessedly incomplete, as there are numerous, even well-known, Genera (73, T5) 38 PRINCIPLES 01' CLASSIl-ICATION. which cannot well be referred to any of his natural orders. 100. The same imperfection occurs in the Fragments of a Natural Method, left by Linnaeus, and it is remarkable that the comparative number of such doubtful Genera is very similar in both these ar- rangements. 101. The foregoing observations concerning Classifi- cation, are also applicable to the Generic distinctions of plants; but in their latter application they are de- duced from all, or any, of the seven parts of Fructi- fication (52), according as each may afford the most clear and essential difference. 102. Generic Characters are of two kinds, the natural and the essential. 103. Natural Generic Characters are a concise, tech- nical, but full description of the seven parts of Fruc- tification of each Genus, in their natural order, as in sect. 52, so as to apply, as nearly as possible, to every known Species. Such are contained in the Genera Plant arum of Linnaeus. 104. Essential Generic Characters consist of the strik- ing and essential differences, between one Genus and another, in any one or more of those seven parts, with respect to insertion, structure, division, or any other permanent mark ; such parts being disposed in each, according to their relative im- portance, for such discrimination, in the Natural Order to which the Genus in question belongs. riUXCIPLF.S OF CLASSIFICATION". 2.9 Characters of this kind are given in the Systemu Natura, and $y sterna Vegetabiimm of Linneeus,as well as in our Flora Britamiiea, and the Genera Plant arum of Jussieu., In the latter are subjoined, in a different type, various accessory or explanatory characters, of great value, respecting the herbage, or general habit, of every Genus. 105. These principles of Generic discrimination are equally stable and important, whether Genera be considered, with Linnaeus, as natural assemblages; or with some other botanists, as commodious arti- ficial contrivances. 106. It seems to me that the soundest most irrefra- gable Genera, have been established by those bo- tanists who believed them to be founded in nature ; those who think otherwise, being prone to recur to minute distinctions, of whose relative importance they have no principle by which they can judge. 107. While Rosa, Rub us, Quercus, Saliv, Ficus, Cy- pripedium, Epimedium, and Begonia exist, it will be vain to deny that Generic distinctions are found- ed in nature, though botanists may, as yet, be verv far indeed from having discovered them all cor- rectly. 40 CHAPTER VII. EXPOSITION OF THE LINNiEAN ARTIFICIAL SY- STEM, SOMEWHAT REFORMED. Ihe Classes are 24, distinguished by the number, situation, proportion, or connexion of the Stamens(58). • The Orders, sub-divisions of the Classes (76*), are founded on the number of the Pistils (59), or rather of the Styles, or Sessile Stigmas; or on the Fruit (61); or on the nature of the different Florets (68) ; or on some character of the preceding Classes ; or lastly, in the 524th Class, on Natural Families. The first eleven Classes are known solely by the number of Stamens, in each Perfect Flower (65). 1. Monandria. Stamen 1. fig. 1. Globba marantina. <2. Diandria. Stamens 2. — 2. Veronica spicata. 3.

The throe next arc known bv a disunion of the Sta- mens and Pistils, the former being in one Flower, the latter in another, of the same species, such being de- nominated Separated Flowers (65).

The Palmce originally constituted an appendix to • this system, because their Flowers were too little known to admit of arrangement by the Stamens and Pistils. But that difficulty is now almost entirely re- nnovcd, and the Genera of this tribe are mostly found ; reducible to the 6th, 21st, or 22d Classes. The Orders of the first 13 Classes, Monandria to IPolyandria inclusive, are characterized solely by the number of the Styles, or sessile Stigmas, in each Per- lect Flower (65). These Orders are more or less nu- i nierous in the several Classes, and are distinguished as follows : 44 EXPOSITION OF THE UNMAN MONOGYNIA. 2, 13, 20. DlGYNIA. Trigynia. 48. Tetragynia.

There is usually an analogy between their respective numbers in the same flower. The two Orders of the 14th Class are distinguished by the nature of the Fruit. 1. Gymnospermia. Seeds naked, usually 4, never more. fig. 22. 2. Angiospermia. Seeds in a Pericarp (61), mostly very numerous, fig. 175. ARTIFICIAL SYSTEM, SOMEWHAT REFORMED. 45 The two Orders of the 15th Class are distinguished by the shape of their Pericarp. 1. Siliculosa. Fruit a Silicula, or Pouch (6*1 :2). fig. 24. 2. Siliquosa. Fruit a Siliqya, or elongated Pod (61:2). % 30. The various Orders of the 1 6th, 17th, and 18th Classes are characterized by the number of the Sta- mens, the Classes themselves being marked by their various modes of union. These Orders therefore bear the same appellations as the first 13 Classes. The Orders of the 19th, or Compound-flowered, Class are marked by the Perfect, Separated, Barren, Fertile, or Abortive nature (65) of the Florets (68). 1. Polygamia-vEqualis. Florets all perfect, each having efficient Stamens and Pistil, and producing one Seed. fig. 57-63. 2> Polygamia-superflua. Florets of the disk- perfect ; those of the circumference, or radius, having a Pistil only : but both kinds forming perfect Seed. fig. 66-69- 3. Polygamia-frustranea. Florets of the disk- perfect ; those of the circumference with an abortive Pistil, or none at all. fig. 64, 65. 4. Polygamia-necessaria.

The Orders of the 120th Class are distinguished bv the number of their Stamens. Gynandria Monandrla. fig. 70-72. Tetrandria, 73-76. Those of the 21st and 22d by the same circum- stance, or by any other character of the preceding Classes founded on the union of the Filaments. The Orders of the 23d are, 1. Mono EC I A. The two or three different descrip- tions of Flowers all on the same plant. 2. DlOEClA. The different descriptions of Flower? on two separate plants. 3. Tiuoecia. The same on three separate plants.

Mushrooms, fig. 129-153. The 3d and 4th of these Orders are added since the time of Linnaeus. The whole will be explained hereafter. The difficulties, or exceptions, to which the above System is liable, are the following : — Number in the parts of Fructification proves not always uniform in one Genus or Species, nor even in the same individual plant. In the latter case Lin- nceus teaches that the central, or terminal, Flower must be our guide, as in Euoin/mus, Monotropa, Chr;j- tosplenium, and Adoxa. When a species is vari- able in the number of Stamens or Pistils, or if one or more species of any genus differ from the rest in those respects, such irregular species are to be named in a synoptical or analytical table at the head of the particular Class or Order to which they techni- cally belong; though placed in due course, likewise, in the proper Class and Order of the Genus of which, independent of such artificial characters, they natu- rally form a part. The same plan is, of course, to be pursued with regard to any species, anomalous in other respects, as the dioecious ones of Valeriana, Lychnis, &c. That this System sometimes puts widely asunder some genera naturally allied to each other (as a few with Ringent Flowers, that by their natural affinity belong to the 14th Class, placed in the 2d because 48 EXPOSITION OF TILE UNMAN they have only two Stamens), is no objection to it on the score of facility or convenience. It does not pro- fess to be a natural arrangement ; and if in many parts it proves so, more is performed than had been promised, or than could reasonably be expected. The 15th and 19th Classes are perfectly natural (except Cleome, badly placed in the former) ; as are, more or less, several Orders, or Sections of Orders, in other Classes. *v1- ' Greater technical inaccurracy occurs relative to some characters, founded on connexion of parts. The Stamens, or Filaments, of several Papilionaceous ge- nera, referred with their strictly natural allies, to Diadelphia Decandria, are perfectly monadelphous. fig. 40. We do not mean merely that their two sets of Stamens are united into one at the base ; but there is really no distinction of two sets, in any part of their structure. Indeed if the ten Filaments are any way .combined, in a Papilionaceous Flower, such is re- ferred by Linnaeus to the Class and Order just men. tioned. If they are altogether distinct, in which case their whole configuration is totally dissimilar from the flat and membranous Filaments of the true Dia- delphia, they belong, though Papilionaceous, to the 10th Class. Culture, and other accidents, produce changes against which no principles of arrangement can pro- vide. Such causes peculiarly affect number in the parts of a Flower, the Stamens, and Pistils, as well ARTIFICIAL SYSTEM. 49 a-, the divisions of the Calyx and Corolla, being fre- quently multiplied by luxuriance of soil, to the great delight of florists, but much to the inconvenience of botanists. So also the Stamens and Pistils are often transformed to Petals, which constitutes a double Mower. In the Classes with separated Flowers, accidents occur with regard to the situation of the Stamens or Pistils. If the structure of the other parts of the Flower be alike, in every individual, both these or- gans are liable to meet in the same Flower; just as, on the other hand, they occasionally are met with sepa- rate, in Classes, or in some Species of Genera, to which united Flowers naturally belong (65). Hence so great a proportion of trees in hot climates, as well as of grasses in all climates, are polygamous ; having the characters of the 23d Class, as defined by its author Linnaeus. But if respect be always had to the acces- sory parts of a Flower (53, 54), as well as the essen- tial ones (58, 59), and those are found different in structure, number, or otherwise, such Flowers must remain permanently distinct. Such only would I ad- mit into the Class Polygamia, by which measure bo- tanists in tropical countries are relieved from one of the greatest of inconveniences. I have even ventured to suggest, Introd. to Botany, ed. 3. 368, that the 2 1st, 22d, and 23d Classes of the Linnaean system might possibly be well reduced to one, under the name of Diclinia (already used by E 50 EXPOSITION OF THE LINNJEAN Jussieu and some other writers), which might contain all genera with separated Flowers, whose accessory organs differ in any respect. This alteration has been adopted by an able practical botanist, whose experience had taught him to approve it, Mr. Frederick Pursh, in his Flora America Septent?*ionalis, published in 1814. He has divided the Class Dicl'mia into the three following Orders. J. Segregate. Flowers not Amentaceous (55:3). 2. Amentace.e. Barren Flowers, at least, in Cat- kins (55 : 3); the Fertile ones not always so. Fruit distinct from the Calyx, fig. 274, 275. 3. CoNlFERiE. Barren and Fertile Flowers in Cat- kins. Fruit a Strobilus or Cone, (61:7) fig. 276. Under each Order of the Linnasan System, are dis- posed the Genera which belong to it, in a regular se- ries, as nearly as possible according to their natural affinity to each other, with the Essential Character (104) of each. The Species are, in like manner, ranged, according to their affinities, under each Gwius, with their Specific Characters. Synonyms are subjoined, with mention of the native country of each Species ; after which follow occasionally compendious descrip- tions, with any useful remarks. Some large Genera are commodiously divided into Natural Sections, by leading characteristics of certain Species taken col- lectively. At the head of every Class, all its Orders are enu- merated; and under each Order its appropriate (u- ARTIFICIAL SYSTEM. 51 nera are arranged, in a Synoptical or Analytical man- ner, according to their shortest, most technical, cha- racters. In these, whatever part of the Fructification affords the most decisive or striking characters in each artificial Order or subdivision, takes the lead, the others following according to their importance. But in the above-mentioned Essential Characters (104), at the head of each Genus, the parts of Fructification, whence those characters are derived, should be dis- ; posed, as has already been observed, according to their relative importance in the particular Natural 1 Order, or Series, to which such Genera belong. These are the principles of arrangement which Lin- naeus appears to have laid down for himself, and i upon which he gradually improved. But in the detail ( of his System he has not always kept them strictly in view ; nor have his pupils, followers, or editors, paid t the requisite attention to them, especially with regard to those intricate or recondite natural relationships, which few of these writers perhaps were competent to observe, and to which, it must be confessed, botanists cof the old Linnasan school have generally paid too little attention. Respecting Nomenclature, it is only necessary to remark, that every Genus should be distinguished by a a name, either of Greek or Latin derivation, or formed out of the proper name of some botanist, worthy of such commemoration. Names of barbarous origin have, however, crept in, by the means of Linnaeus E 2 52 NOMENCLATURE. himself, contrary to his own wise laws. Genera have also been dedicated to abundance of persons, who have no claim to this honour. Corrupt names, com- posed of other generic appellations, already establish- ed, though strictly and judiciously prohibited by all classical botanists, have here and there been intro- duced. Of these the worst of all are made up of two such established names as Calamagrostis. Future general writers on Botany, of competent authority, must reform these abuses. No authority can sanction their continuance. If any indulgence be admitted, it may perhaps be in favour of a few well-sounding ge- neric names of barbarous origin ; for there can be no question that Pliny, and even purer Latin writers, would have adopted such names, properly modified, had they treated of the new plants of foreign coun- tries. The generic name being fixed, each Species must also be designated by an appropriate concise appel- lation, of a single word if possible. This should be either a characteristic adjective, expressive of the cha- racter, aspect, colour, quality, or use of the Species ; or of some substantive, not necessarily agreeing in gen- der with the generic name, and therefore always be- ginning with a capital letter, by which some circum- stance in the history of the plant, or some synonym, may be recorded. Important or permanent Varieties (74) may, ^ ith propriety, be noticed. These are conveniently marked SPECIFIC CHARACTERS. 53 with the Greek letters, numbers being reserved for Ge- nera and Species. It would be well for every person who undertakes to write a systematic work on Botany to consider these leading principles of Linnaeus, and to study with care those more particular ones, laid down in his Fundq- menta Botanica, as well as his Philosophia and Cri- . tica. If his rules be faulty or unnecessary, they should be expunged ; but no good writer will transgress them through ignorance or neglect. His principles for the distinction of Species should be studied and contemplated over and over again, by every person ambitious of permanent botanical fame, beyond the reach of the fashions of System. This de- partment of Botany Linnasus justly terms art is robur, the strength, or sinews of the science. Species are perhaps the only distinctions which are indubitably natural; and to stamp them clearly, as well as con- cisely, is the most important, perhaps the most dif- ficult, office of the philosophical botanist. No one yet has equalled Linnaeus; nor has any one swerved from his rules, in theory or in practice, but for the worse. No intended improvement in this department has come under my inspection, that does not appear to me worse than indifferent. I speak with the greatest respect and deference for the authors of such projects, which it would be invidious to particularize, and which have, doubtless, been well intended. The more com- mon faults in these compositions arise from negligence 54 IMPORTANCE OF or inability, from a want of deep study of the subject a confusion or inaccuracy of ideas, a feebleness of style or expression, or a want of command of language. I have chosen to conclude this chapter with the subject of specific characters, because it is of the most fundamental importance, and the most difficult in practice. It is the only sure ground of what Linnaeus justly declares as the test of a good botanist, the know- ledge of the greatest number of Species. {Phil. Bot. sect. 256.) Now this knowledge, if merely empirical, can be tjut pf little value or certainty. Its dignity and solidity must consist in an, intimate acquaintance mm the comparative or respective importance of different characters, in different orders, tribes, or genera of plants. Several general rules indeed may be given,; but scarcely one of those is without exception ; and i particular rules apply to almost every natural assem-! blage throughout the vegetable kingdom. The latter i are only to be attained by acute observation and great experience. The 8th chapter of the Philosophia Botanica of Linnaeus, entitled Differentice, contains a full display of the ideas of that great writer, the first who ever undertook to consider this matter in a philosophical light, or to lay down any rules for the guidance of others. We shall give an epitome of his principles, recommending his reasons and illustrations, in the chapter just cited, to the attentive consideration of the student, who, before he attempts to apply them to SPECIFIC CHARACTERS. 55* practice, should give his days and nights to the sub- ject. A Differentia Specified, Specific Character, or as Linnzeus usually called it Nomen Specificum, should comprehend such characters only as are requisite, or sufficient, to distinguish a plant from every other spe- cies ot' the same Genus. Such therefore is not a de- scription, but a difference, and where only one Spe- cies exists, a Differentia Specified is an absurdity. If it attempts to contrast the plant with the Species of any other Genus, it is fallacious and erroneous. A Specific Character therefore is the essential pe- culiarity of the full description, or complete idea, of every plant, whether drawn out in detail, or existing in the mind of the author. All accidental circumstances are necessarily to be excluded, such as Country, Situation, Duration, Eco- nomical Uses, the Name of the Discoverer, &c. All marks universally variable are also to be omitted, among which are Colour, Smell, Taste, Size, Hairi- ness in general, Curling of Leaves, Doubling of Flowers, or any kind of Monstrosity. • The direction of the hairs of Plants, as on the Ca- lyx and Flowerstalk in Mentha and Myosotis, the Stem of Papaver, and some other instances, not no- ticed by Linnaeus, forms one exception to the above rule ; and perhaps the presence or absence of a glau- cous hue in the herbage is another. Characters which presuppose any knowledge of 00 RULES FOR other plants, even of the same Genus, in the reader, as well as any allusions to the rarity or frequency of a plant, are manifestly faulty. The Root (7) often affords solid specific distinctions, but is not infallible ; nor can it always, in cultivated plants, or in dried specimens, be examined, or pre- served. Stems (12) frequently afford clear and certain di- stinctions, in their forms, postures, angles, wings, or other particulars. Leaves (30) abound in the most elegant and un- exceptionable characters for specific discrimination, in their situation, form, division, surface, margin, veins, and even pubescence. But scarcely any one mark concerning them is absolute, throughout all plants whatever, and experience only can teach, in every case, what is most to be relied on. Appendages (47) are usually very serviceable in specific characters, especially the Stipulas, as to their presence or absence, situation, form, or even duration. Inflorescence (48) is declared by Linnreus to yield the best of all specific differences. Phil. Bot. sect. 279. The importance of the distinctions to be derived from hence is so great, that some botanists, especially of the French school, do not scruple to found some of their Generic Characters upon it. Even Linna?us is justly charged with having had recourse to the Inflo- rescence, in arranging the Genera of the Umbelliferous tribe (48 : 7), though the principle is disguised under SPECIFIC CHARACTERS. 57 the idea of an Aggregate Flower (69). Our great leader is the more censurable, as the flowers and S Seeds ol those Plants, properly studied, afford all-suf- iicient Generic Characters. The parts of Fructification themselves, so far as I their differences do not enter into the Generic Cha- racters, often display most excellent Specific marks. Such now and then serve to divide a genus into Sec- tions; as the Petals in Iris, and the Styles in Hype- i ricum. The more concise a Specific Character, the better it is. As in philosophy, it is not allowed to recur to two causes for the explanation of any phenomenon, when one is sufficient, so if one idea will serve to di- stinguish a Species, no more should be admitted. If more be necessary, as is generally the case in large Genera, they should be so disposed and contrasted, in the several Specific definitions, as to strike the mind at once forcibly and distinctly. This cannot be done if characters be much extended. Linnaeus has there- fore limited each definition to twelve words. There is no magic in this number, but I believe it is seldom exceeded with any good effect. Much will depend, after all, on the wording and construction of the sen- tence. A weak character of half a dozen words may be puzzling and insufficient ; Avhile a much longer may be clear, and readily conceived as well as compared, at one view. All the terms and definitions should be precise, lite- 38 PUNCTUATION OF ral, and unambiguous. They are not allowed to be expressed in the comparative degree, though some- times admitted, of late, in the superlative. They must be positive, not negative ; devoid of obscure compa- risons ; contain no adjective but what follows its sub- stantive; no article, connecting particle, or parenthesis. Linnaeus has adopted an arbitrary mode of punctu- ation in Specific Characters, in which the usual power of the different signs is reversed. He uses a Comma ( , ) to separate the different parts of the plant which come into the Specific Character. This is most fre-i quently wanted, as between the Stem and Leaves andi Inflorescence, if they all happen to occur. A Semi-| colon ( ; ) separates two descriptions of the same or- gan, as Radical Leaves from the rest. A Colon ( : ) is introduced between the several parts or divisions of any one organ, as the segments, margin, or veins of a Leaf. A Period ( .) of course, as usual, closes the sentence. The intention of this method seems to be, to lead the mind to a longer pause, in proportion as the parts under consideration are most nearly related. To practise it quite correctly requires more attention than is usually bestowed ; and even Linnaeus, or his printer, makes frequent, though not very serious mis- takes. The following examples are correct : — Biscutella siliculis glabris,J'oliis lanceolatis serratis. Dentaria foliis inferioribus pinnatis ; sitnwiis sim- plicibus. Cardamine foliis pinnatis : foliolis quints incisis. SPECIFIC CHARACTERS. 59 •Melochia Jloribus umbellatis axillaribus, capsulis pyramidatis pe?itagoni$ : angulis muwonatis, fa- His tomentosis. Those who describe new plants would do well, in general, to keep in view the laws of Specific distinction in their names likewise, though with less strictness ; avoiding always what is trifling, incorrect, or erroneous; und selecting what may best impress the imagination, < or assist the memory. No name whatever should be i considered as of any authority, unless printed by some author who gives at the same time a specific characr ' ter ; though a judicious writer will always adopt what I has, by any means, been received by the publick, if i it be not materially objectionable, 60 CHAPTER VIII. EXPOSITION OF THE NATURAL SYSTEM OF JUSSIEU. The Classes are 15, not distinguished by any par- ticular appellations. One of them is Acotyledonous (90, 91) ; three are Monocotyledonous (88) ; the re- maining eleven Dicotyledonous (89). The Orders are 100, distributed in natural series under every Class, and each defined by rather full definitions, taken, in the first place, from the parts of Fructification (52), and illustrated by secondary cha- racters, founded on any other circumstance. The Genera stand, in one or more sections, accord- ing to their respective affinities, and with their Essen- tial Characters (104) under each Order, at the end of which are usually many valuable critical remarks. There is at the end a very large assemblage of Planta. inccrta sedis; Genera not reducible to any of these Orders. These are, for convenience, artifi- cially arranged, by the Corolla (whether inonopetalous, polypetalous, or wanting), the situation of the Ger- men, and the number of Styles and Stamens. Many of the Genera have subsequently been reduced to their proper Orders. TYLEDONES (90) f Stamens hypogynous (97) TOCOTrLEDONES I perigynous x,8) epigynous 61 INDEX TO JUSSIEU'S CLASSES.

Soc. v. 8. 330, has first correctly defined the genera of this Order, by the shape of the Stamen, or Filament, which affords ex- cellent essential characters, concurring with other differences in habit and inflorescence, and all together C establishing the most natural genera possible. The Order is well divided by him and Mr. Broun, Prodr. N. Holl. v. 1. 307, into real Cannes, com- prising Canna, Maranta*, Thalia, Phrynium, with (certainly) Myrosma; and SciTAMlNE^l, as Linnaeus terms the whole, embracing all the rest. The CannecE have a simple Anther, and are scarcely fragrant in jany part; their Style is petal-like, or tumid, with a i nearly simple, naked Stigma. The Scitaminea, fig. 1., I have an Anther of two distant lobes, meeting around t their thread-shaped Style, whose Stigma is dilated, cup-shaped, and fringed. The plants are in some part or other, if not all over, powerfully aromatic or pungent. The character of this last Order may, ac- cording to our judgment, be thus more correctly . given.

Gartner and Brown consider the tubular part of the Embryo, in these plants, as a peculiar organ, termed Vitellus (62 : 3), whose office is conceived by the former to be the nourishment of the Embryo, though the Albumen is acknowledged to serve no other purpose.

Dr. Svvartz and Mr. Brown have greatly improved the history of this Order, and augmented its genera, of which New Holland affords many new ones.

Brown. The Stamens, according to this able observer, consist of 3 Filaments, com- bined together, as well as more or less united to (he Style, within the upper Calyx-leaf, opposite to the Lip; the 2 lateral ones almost always abortive, and generally short, or obsolete, the intermediate one only bearing an Anther. In Cypripedium alone, as far as hitherto observed, the latter only is abortive, both the side ones being antheriferous. Anther of 2 cells, which are either separate, and fixed to the sides of the Column (or Style), often extending beyond them ; or brought together into a simple Anther, either parallel to the Stigma, immoveable and permanent, fig. 71, e, or terminating the Column in the form of a, generally moveable, deciduous lid, fig. 77 and 78, a; each cell being divided internally by one, seldom three, longitudinal partitions.

The author confesses his dis- satisfaction respecting the last five genera, and not without reason. Mr. Salisbury, in Sims and Konig's Annals of Bot. v. 2. 69, first I believe showed Nym- ph(Ea and it's allies, amongst which are my NupJtar and Cyamus, (the latter Jussieu's Nelumbium,) to be dicotyledonous, and therefore they can have no place here; see Ord. 62. Trapa is well explained by Gasrtner, as having two, though very unequal, Co- tyledons. Proserpinaca has two very distinct equal ones. Class 5.

In the two latter the Stamens, being occasionally I, 2, or 3, and bearing no fixed analogy to the Calyx, are scarcely to be call- ed definite. Mr. 13rown denominates this Order Chenopodece, with DeCandolle, and remarks that it has no character to distinguish it from the Amaranth'^ Ord. 30, though there is a difference in habit.

Psyllium of Tournefort, with Plant ago, fig. \66, and Littorella, are all the genera. The two former are united by Linnaeus, DeCandolle and Brown; the last is monoecious. Much doubt attends this singular and unconnected Order. Mr. Brown, like Linnasus, gives the evident Corolla its proper appellation, there being a distinct Perianth, in 4 deep segments, besides. Ord. 32. Nyctagistes. " Calyx tubular, like a Corolla, either naked, or surrounded by an outer Calyx. Germen, Style and Stigma simple.

Mirabilis, fig. 1 67, ( Nyctago Juss.) Boerhaavia, and Pisonia, with Abronia of Jussieu (Tricratus L'Herit.) and Buganvillcea of Commcrson, compose this Order, to which O.vybciplius of L'Heritier, Curt. Mag. t. 434, must be added. The Calyx of Jussieu is the evident Corolla of other botanists, nor do we perceive what is gained by his paradoxical appellation. Still less does the apetalous character of his 7th Class suit the following Order. Ord.33. Plumbagines. " Calyx tubular. Co- rolla of 1 or many Petals, beneath the Germen. Sta- mens definite, inserted either beneath the Germen, or into the Corolla. Germen solitary, superior. Style 1 or many. Stigmas many. Capsule sepa- rating into several valves at the base only. Seed so- litary, pendulous from a thread-shaped stalk, origi- nating from the Receptacle of the Germen. Embryo oblong, flat, surrounded by a farinaceous Albumen. . Stem herbaceous, or somewhat shrubby. Leaves al- ternate," (undivided). Plumbago and Staticc, fig. 16S, (the latter subdi- vided by Brown) are the only genera. This Order and the 3 1st are arranged by Mr. Brown amongst his Monopetalce. We cannot but remark a great inaccuracy in this part of the Jussieuan System, as to technical cha- racters respecting Calyx and Corolla; but without any reflection upon it's illustrious author. Such are incidental to every attempt of the kind, nor can art ■ CI. 8.] LYSIMACHLE. 95 keep pace with nature. It seems proper nevertheless that these three last Orders should be removed to some of the following Classes. . Class 8. Dicotyledqnes. Corolla monope- talous, hypogynous. " Calyx of one leaf. Corolla regular or irregular, bearing the Stamens, which are definite, and gene- rally alternate with its segments when of equal number. Germen superior, in general simple, with one Style; but in some Apocinei, Ord. 47, the Germen is double, without any Style. Stigma sim- ple or divided. Seeds either naked, or more fre- quently in a Pericarp, either pulpy or capsular, of 1 or many cells." A great and important Class ; whose 15 Orders follow one another in a tolerablv natural series. Some if are generally furnished with Albumen, others not ; but this difference bears no analogy to the other cha- racters of affinity, or of distinction, between the Or- ders. Ord. 34. Lysimachle. " Calyx divided. Corolla mostly regular, five-cleft, bearing as many Stamens opposite to the lobes. Style 1. Stigma rarely cloven. Fruit of 1 cell, with many Seeds, often capsular, with a central unconnected Receptacle. Stem herbaceous. Leaves opposite, or alternate." Some have a Stem, as AnagalUs, fig. 169, Lysi- machia, Hottonia, Limosella, Sec. ; others radical 96 PF.D1CULARF.S, ACANTHI". [CI. 8.

Mr. Brown, following Ventenat, calls this Order Primulacea?, and has separated from it some of the appendix, by the name of Lentibularice, given by Richard. Their Corolla is irregular, with a spur. Stamens 2. Albumen none. Embryo sometimes un- divided— that is, to speak plainly, monocotyledonous ! Ord.35. Pediculares. "Calyx divided, per- manent, often tubular. Corolla usually irregular. Stamens definite. Style 1. Stigma rarely cloven. Capsule of 2 cells and 2 valves, each having a central partition, bearing the numerous Seeds. Stem gene- rally herbaceous. Leaves, as well as Flowers, oppo- site or alternate, with 1 Bractea to each Flower." Erifius, Castilleia, Euphrasia, Bartsia, fig. 171, Pedicularis, Rhinanthus, Melampyrmn, are genuine examples of this Order, all turning more or less black in drying, and well distinguished by their Anthers and Seeds. Their Stamens are 4, 2 longer than the rest. Hyobanche, Orobanche, Lathrcea, &c, are less strict- ly akin to these; and Polygala, with Veronica, fig. 2, and Sibtkorpia, fig. 176, are but slightly related to them or to each other.

Acanthus, Barlcria, Ruellia, Justicia, fig. 172, with some others, constitute this very natural Order, which Mr. Brown has deeply studied, and happily il- lustrated, Prodr. Nov. Holl. v. h 472. He notices the various, equal or unequal, simple or double, forms of the Anthers, and the awlshaped support of each Seed, which is very peculiar, though not invariably present. The Seeds have no Albumen. There is often a rudiment of a fifth Stamen. Ord. 37. Jasmines. " Calyx tubular. Corolla : regular, tubular, rarely deeply four-cleft, occasionally wanting. Stamens 2.

Syringd {Lilac Juss.) and Frawmtts) with Chio- ■ nanthus, Olea, fig. 173, Jasrrimum and Ligustrum > are examples of this Order, which abounds with 1 elegant Shrubs, whose fragrant Flowers are highly | valued.

Mr. Broun separates the true Jasmines, whose Seeds are erect, with hardly any Albumen, and their Corolla salver-shaped, in from 5 to 8 segments, with an imbricated twisted Aestivation ; from the Olc'inae of Hoffmansegg and Link, whose Seeds are pendulous, with a copious, dense, fleshy Albumen, and a. deeply four-cleft Corolla, sometimes wanting. Ord. 38. Vitices. " Calyx tubular, often per- manent. Corolla tubular, for the most part irregular in the limb. Stamens generally 4, didynamous, rare- ly 2, or 6. Style 1. Stigma variously shaped.

Fruit capsular, of 2 cells, and 2, more or less deeply separated, valves, (which are now and then cloven,) naked and concave within; the Receptacle central, bordered, bearing Seeds, ge- nerally numerous and minute, on both sides, and serving as a partition, meeting the inflexed edges of the valves. Stem herbaceous, rarely shrubby. Leaves opposite or alternate, seldom compound. Flowers bracteated." Buddleia, Scoparia, Scrophularia, Gerardia, An- tirrhinum, fig. 175, Hemimeris, Digitalis, and some others, give the true idea of this Order. Calceolaria, Wulfenia, and Commerson's Bcsa, are the diandrous genera. There are 2 Sections of numerous genera, one with opposite, the other alternate, Leaves, marked as "akin to Scrophularia Among the first are Columnea, Besleria, Gratiola, Lindernia, Mimulus ; those with alternate Leaves being Schwalbea, Schucnkia, and Broxvallia. Mr. Brown brings hither some of the 35th Order, as Veronica, fig. 2, (certainly with great propriety,) including Jussicu's Hebe. He reckons Gratiola one of the true Scrophularia, as well as Euphrasia, part CI. 8.] SOLANEJE. 101 of Buchnera, with Mimulas, and Limosella, to which New Holland has furnished several new additions. Respecting Limosella, as being much better placed here than in the 34th Order, there can surely be no doubt. Sibthorpia and Disandra belong, without question, to the Scrophularice, not to the Pedicu- lares. Except in the Stamens, and perhaps Corolla, there is little affinity between this Order and the Labiatce. Their qualities are almost totally different; nor is there any analogy between the Fruit of each. The bulk of the 39th makes the 1st Order in Linnaeusrs Didyna- mia, that of the 40th the 2d Order of that Class. Ord. 41. SoLANEiE. " Calyx more or less deeply o-cleft, often permanent.

The Flowers are rarely 4-cleft ; often irregular, as occasionally in Solatium, which genus cannot safely be divided on that account. The Albumen is more cor- rectly described, by Gartner and Brown, as fleshy, in- closing the curved Embryo. This curvature, and the plaited Aestivation of the Corolla, which is not ringent, or 2-lipped, Mr. Brown reckons the most essential dif- ferences between this Order and the Scrophul-arice. Bontia, BrunJ'elsia, and Crescoiiia are subjoined as akin to Solanece. The genuine plants of this Order are narcotic, foetid, often very dangerous, termed by Lin- naeus Luridee, or Gloomy. Vcrbascwn however, abounding with mucilage, is only mildly sedative, and perfectly safe for internal use, though intoxicating to fish. Ord. 42. Boragine^e. " Calyx 5-cleft, perma- nent.

Stem in most cases herbaceous; rarely shrubby or arboreous. Leaves alternate, often harsh." (Stipulas wanting.) These, the Aspcrij'olia of Ray and Linurous, com- pose on the whole a very natural assemblage ; of CI. 8.J COXVOLVULI. 103 which Heliotropium, Echium, Lithospcrmum, fig. 178, Pulmonaria, Onosmct, and perhaps Coldenia, all which hav e a naked-mouthed, or pervious, Corolla ; with Symphytum, Lycopsis, Myosotis. Anchusa, Borago, Asperugo, Cynoglossum, and Trichodesma of Brown, whose tube is closed with valves, constitute indubitable examples. Tournefortia, Ehretia, and Cordia, (the latter comprehending Varronia,) are also retained here ; but Mr. Brown proposes to separate Hydro- phyllum, Ellisia, and Jussieu's Phacelia, as having a copious cartilaginous Albumen, compound, or at least deeply lobed, Leaves, and a capsular Fruit. The true Boraginece are allied by their Seeds to Labiates, Ord. 39 ; but differ in their pungent or warty, not hairy, pubescence ; mucilaginous, not aro- matic, qualities ; alternate, not opposite, Leaves; and blue, rather than crimson or purple, Flowers, ex- cept in the bud. Messerschmidia and Ccrinthe differ from the rest in having a kind of two-celled twin Cap- sule, or Nut; and Cerinthe has a glaucous, smoother, though warty, habit, with reddish or yellow Flowers. Qnosma too is always yellow-flowered. The change in the Corolla of the Boraginece in general, from bright red, to a vivid blue, as the Flower expands, apparently caused by the sudden loss of some acid principle, is a very curious phenomenon.

Embryo curved, the radicle inferior. Plants shrubby, or often herba- ceous, twining in several instances, sometimes milky. Leaves alternate, very seldom imperfectly opposite." Mr. Brown notes the want of Stipulas, and the pre- sence of a small mucilaginous Albumen, as well as the corrugated Cotyledons (always attendant on Seeds whose number is definite). He differs from Jussieu with regard to some genera, but the follow ing are in- dubitable specimens of the Order. Sect. 1. With 1 Style. Convolvulus, fig. 179, and Ipomaa.

The insertion of the Corolla, characteristic of this Class, is not very apparent, and I observe that Mr. Brown does not allude to such insertion, but, even in the character of the Ebenacete, contradicts it. In fact nature and art accord very ill in this part of the Sy stem. The first Order might, in the main, be re. moved to the foregoing Class, with whose character it agrees : while the fourth goes most readily and natu- rally to the eleventh Class, having some relationship to the tenth. But the great difficulty consists in the se cond and third Orders of this ninth Class, in which there is really no sucli insertion of the Corolla as above mentioned * ; and the inferior Germen of Vaccbiium is an insurmountable stumbling-block. Nothing could justify, in a professedly natural system, the removing this last genus from the neighbourhood of Erica and Azalea ; and it were better to have met the difficulty by an open avowal, with some contrivance of an ar- tificial nature, making Vaccbiium an exception. The true Rhododendra and Ericce would go very well into the eighth Class. It must be observed that their Sta- mens are often hypogynous, really inserted into the Receptacle under the Germen. Ord. 49.

Artedi, the early friend of Linnaeus, who devoted himself to the study of the Umbclliferce, sug- gested, or adopted, this plan. But those parts are often variable in the same species. The regularity or irre- gularity of the Petals also, and the perfection or par- tial imperfection of the Stamens or Pistils, have been resorted to, and do perhaps often afford good marks. The simple or divided form of the Petals is very ma- terial. But the figure, margin, ribs, angles, and sur- face of the Seeds yield excellent characters, allsuffi- cient for the establishment of good genera, though not yet perfectly well applied to use. The earlier syste- matic botanists, and more recently Crantz and Cus- son, have had this object in view. Hoffmann and Sprengel are now intent upon it. The ProdromUs of the latter, published at Halle in 181 3, does honour to it's author, though his Species Umbell'iferarum minus cognita, published five years later, may serve to show that his ideas of genera are not yet settled. It would be superfluous to give the detail of Jussieu's 4 Sections. Sprengel's are as follows : 1. Fruit compressed, flat.

Perhaps these, especially the last, might be removed to the next Order. The Ranunculacece have lately been admirably illustrated by Prof. DeCandolle, in his Regni Vege- tabilis Sy sterna. Nat urale, v. 1. 127, both with respect to genera, species and synonyms. This learned writer observes, that the genuine plants of the Order in ques- tion have external or dorsal Anthers ; the spurious ones, Aetata (which includes Cimicifuga), Xanthor- rhiza and Pceonia, have interior Anthers, that is, turned towards the Pistils. He reduces Atragene to Clematis ; except A. zeylanica, which constitutes a genus, called by him Naravelia, a name of barbarous origin, and it seems better that Atragene should re- main to designate this genus.

This Order, constituting Linnaeus's 15th Class, is so natural in itself, that we can scarcely say whether any real affinity exists between it and any other. Hy- pecoum, in the last, betrays a slight resemblance, rather than a relationship, to this ; as Cleome does in the following ; but this last genus is incorrectly referred by Linnaeus to his Tetradynamia, according to any rule that I can discover. The genera of Cruciferee, in which Jussieu follows Linnaeus, are among the least satisfactory in either of their systems. Mr. Brown, in Ait. Hort. Kew., ed. 2. v. 4. has greatly improved them, taking into account the position and direction of their Cotyledons, whether spiral, doubled, or flat; incumbent, folded together upon the Embryo, or decumbent, folded con- trarywise, their edges meeting the Embryo. The num- ber of Seeds also lends occasional assistance, in the Siliculosa at least. In some few instances, 2, or even 4, of the Stamens are wanting. Crambe, Coronopus, Peltaria, whose Pouch does not burst, Isatis, Vella, Teesdalia Br., fig. 25-27, Iberis, Thlaspi, fig. 23, 24, Lepidium, Farsctia, and Lunaria, are among the best genera in Tetradynamia Siliculosa ; as are Arabis, Brassica, Sinapis and Raphanus in T. Si- liffuosa. Mr. Brown's Makomia appears more satis- 140 CAPPARIDES, SAPINDI. [CI. 13. factory than his Maitkiola, as separated from Cheir- anthus. Ord. 64. Capparides.

Jussieu has hinted an ingenious idea respecting the genus Euphorbia, which Mr. Brown, Bot. of Terra Austr. 24, has fully developed, that the Flowers, even in this instance, are monoecious. The Calyx and Petals of Linna3us are considered by these writers as an Involucrum, containing several Barren Flowers, 186 CUCURBIT ACEili. [CI. 15. around a solitary fertile one. But Mr. Brown alone has asserted each of the former to consist of a mere Stamen, articulated with the partial Stalk of this sim- plest of all Flowers, there being no Corolla nor Pe- rianth, the Scales at the base being rather of the na- ture of Bracteas. The Fertile Flower in the centre is, in like manner, a naked Pistil, whose Germen is sessile on a similar Stalk.

The question of the natural or artificial character ' fif Jussieu's System has been ably discussed by the o 194 EMENDATIONS celebrated Mr. Roscoe, in Tr. of Linn. Soc. v. 11. 65, who, in showing that this method involves se- veral as unnatural assemblages as the professedly ar- tificial system of Linnaeus, contends, that little is to be gained by it's adoption, with respect to a confor- mity to nature. Every one must also perceive, that no use can be made of any such system, in the prac- tical or analytical examination of plants. Natural Orders indeed must, in future, be studied by all who deeply contemplate the Vegetable Kingdom, and some links of connexion, or points of discrimination, can- not but be kept in view between them. We require a cabinet, as it were, with cells or drawers, where we may find each Order as we want it ; and Jussieu s classification, with all it's unavoidable imperfections, goes much beyond any system previously invented, in the natural assemblages which it produces. Never- theless, Linnaeus has truly observed that Natural Or- ders are related to each other by so many points, that they rather resemble a geographical map, than a con- tinued series ; which he has attempted to illustrate by example, in his Pr&lectioncs published by Giseke. There remains therefore, in the study of natural clas- sification, only a choice of difficulties ; and while we labour to bring plants together, as naturally as pos- sible, in groups or families, for their mutual illustra- tion, we must perpetually relax or vary those general ties, of which we can, as yet, obtain but very con- fined and imperfect views. Hence therefore I am OF JUSSIEU. 195 • a almost inclined to revert to the idea of Linnaeus, that • vwe are not competent to define technically any na- • ttural orders, without so many, and such paradoxical, ) (exceptions, as to destroy all consistency. The labours ■ ( of his successors too often illustrate and confirm this t (opinion, by their failure in the details of the subject. ■ The learned and candid DeCandolle, (who first has i (claimed, from the botanists of his own school, the i i honours clue to Linnaeus, relative to the principles of 5 i natural arrangement, Theorie Elem.p. 60 Sec.,) though ■ I he has successfully defined several Orders, is obliged e I to have recourse to an artificial distribution of them, ! ' which I have mentioned above, and to which the fol- s 1 lowing is the key. > i Class 1 . Dicotyledonous. Corolla polypetalous, hypogynous. I 2. perigynous. 3. ■ Corolla monopetalous, perigynous. 4. hypogynous. 5. Flowers apetalous, or with one in- tegument only. 6. Monocotyledonous. Flowers phaenogamous. 7. ■ cryptogamous. 8. Acotyledonous. Leafy, and with Organs of impreg- nation. 9. Without leaves, or any known Or- gans of impregnation. The able author proposes this method, as less at 1 ' variance, than any other, with natural affinities, but • : still as serving merely for convenience, nor does he i i attach to it any further importance. o 2 196 VENTENAT. The Genera Plantarum of Jussieu, with all his characters and remarks, have been translated into French by Ventenat, who has interspersed several additional observations. His work makes four octavo volumes, the first containing a dictionary of Botany. The last, besides a general analytical table, is enriched with plates of the fructification of every one of Jus- sieu's Orders, drawn by the masterly hand of Re- doute\ For such a purpose, however, the very best figures are hardly sufficient. Nothing is so instructive as Nature herself ; and the student who has made sufficient progress in Botany to understand the fore- going explanations of Jussieu's System, will be at no loss to procure examples, of the greater part of his Orders at least, by the dissection and comparison of whose structure he will gradually become familiarized with the subject, though it's details are inexhaustible. 197 CHAPTER IX. COMPARISON OF THE NATURAL ORDERS OF LIN- N-EUS WITH THOSE OF JUSSIEU. The present publication would be incomplete with- out some account of the Fragments of a Natural Me- thod, as Linnaeus terms his performance, subjoined by this great botanist to the 6th edition of his Genera Plantarum, an ample commentary upon which, col- lected partly from his lectures on this particular sub- ject, was published at Hamburgh in 1792, by Prof. Giseke, under the title of Prcelectiones in Ordines Naturales Plantarum. An exposition of these Linnaean Orders, which amount to ,58, is before the publick in the 2d volume of the Supplement to the Encyclopedia Britannica, published at Edinburgh, in which I have extracted what appeared to me most valuable in the above Prce- lectiones, interspersing some very curious particulars, from unpublished notes of Linnaeus, in my possession, with a few original remarks: I have also taken a brief comparative view of Jussieu s system at the end. Having in the present volume more fully explained the latter, I shall here reverse the mode of comparison, and place some of the remarks and illustrations in a different light, with a few additional matters. The name of each Linnaean Order is, in the fol- 198 COMPARISON OF THE NATURAL ORDERS OF lowing table, placed first, and where no particular ex- planation is necessary, or there is no very material disagreement, the generally corresponding one of Jus- sieu is merely named ; with it's appropriate number, to enable the reader to turn to each Order in it's pro- per place. 1. PalmjE — PalnuB Juss. Ord. 11. Linnaeus proposed latterly to remove from hence Cycas and Zamia, which he, like Jussieu, considered as Tilices, but which Persoon, and Brown, Prodr. N. Holl. v. i. 346, have more properly disposed in a new Order, called Cycadece. Linnaeus also meant to take away the section (3, in which the Fruit is in- ferior and many-seeded, and which consists of Stra- tiotes, Hydrocharis and Vattisneria. See Jussieu's Hydrocharides, Ord. 22. 2. Piperitje — Aroideee 7. Pipe?* only is referred by Jussieu to his Urticce 9$\ and Saururus to Naiades 6. 5. Calamari2E — Cyperoidece 9- Sparganium and Typha, subsequently removed from hence to his Piperita by Linnaeus, as akin to Zostera, make by themselves Jussieu's Typha; 8. 4. Gramina — Graminece 10. About the plants of this Order, the true Grasses, only one opinion can exist. 5. Tripetaloideje — Junci 13. Calamus is properly considered by Jussieu as one of the Palnitf, Ord. 1. LINN7EUS WITH THOSE 0E JUSSIEU. \99 6. EnsaT/E — Irides 1 8, with some of the Junci 1 3, aand their allies. 7. Orciiide.*, — Orchideas %\. Linnaeus's manuscript indicates Kampferia as be- traying an affinity to this Order in the next, but it is cchiefly in general aspect. 8. SciTAMiNEiE — Cannes 20. 9. SpathacEjE — Narcissi 17, except Allium, re- tferred by Jussieu to his 16th Order, and Colchicum, tto his 13th. 10. Coronari-ZE — Asphoddi 16, some Lilia 14, Bromdice 15, with some of the Narcissi 17, and of I the Junci 13. 11. Sarmentace^ — A few of the Lilia 14, be- gin this Order, but it chiefly consists of the Aspa- ragi 12, with the Mcnisperma 77, and Aristolochia; 23. Centella is to be erased, as not distinct from Hydro- cotyle. Linnaeus, in his manuscript notes, justly observes, that part of this Order is monocotyledonous, part di- cotyledonous. He adverts also to Nymphcea, as hav- ing, in like manner, even some species with one, others with two, Cotyledons. This is a mistake into which Gaertner and Jussieu have likewise fallen. See the foregoing exposition of Jussieu's system, Ord. 22 and 62. It appears from Gisekes publication, pref. 20, that Linnaeus kefk from his pupils his ideas respecting Nymphcea, not having, perhaps, satisfied his own mind. He seems to have thought the existence of such a differ- 2Q0 COMPARISON OF THE NATURAL ORDERS ence in the Cotyledons of one genus, might well justify him in not dividing an Order on that account, and possibly cherished this idea, as an irrefragable proof of his position, that no character whatever was free from exception in natural orders. Neither the de duction, nor the fact as to Nymphcea, is now ad mitted, and yet the Lent ibular ice of Brown, see (Ord. 34) p, 96, and Cuscuta, see Convohuli, are strong ex^ ceptions. 12. Holerace.e — A large Order, of which the 1st section is composed of many of Jussieu's Atr'i plices 29 ; the 2d of more of the same, with Calliga- num, one of his Bolygonece 28 ; the 3d of Axyris only, one of his Atriplices ; the 4th of some Ama- ranthi 30, and some Atriplices ; the 5th of Poly^ gonece 28, with Begonia their ally in habit, see a re^ mark on Jussieu's 52d Order ; the 6th of Kyssa, Mi- musops, Rhizophora and Bucida ; the 7th of Anacar- dium (removed by a manuscript note from the 6th section), Laurus, Tinus, Winterania and Heistcria. There is no analogy between these two latter sections and any of Jussieu's Orders. His Lauri 27, a good Order, was not perceived by Linnaeus. 13. SuccuLENTiE — Cactus, one of Jussieu's 85th Order, with Some of his Portulacecc 86, and Ficoi- decB 87, make the 1st section; Sempej^vivce 83 are the 2d ; some more Portulaccct chiefly compose the 3d ; and Saxijragie 84 are the 4th section of this Order, in which Linnasus was guided by habit, and OF LINN7EUS WITH THOSE OF JUSSIEU. 201 ifussieu, tracing nearly the same affinities, was much embarrassed for technical characters. 14. Gruinales — Ger&ma 73, and some of the « irirst section of Rutacea 81, with Oralis, Linum, and ^ u few ambiguous genera, as Aldrovanda, T)roscra, • iand Averrhoa, make up this Order. Linnasus has • mdded several, more or less happily, in manuscript. 15. Inundate — are analogous to Naiades 6, nd require as much correction. 16. Calyciflor/E — part of Elczagni 24. 17. Calycanthejnle — contain many Onagrce 88, .with the Melastomce 90, and Salicarice 9 1 • 18. Bicornes — Rhododcndra 50, and Erica 51. 19. HESPERiDEiE— Myrti 89. 20. RoTACEiE — Lysimachice 34, chiefly sect. 1, and Zentiance 46. A separate section comprises Hyperica 68, and ( -Jisti 80 ; at least the genuine Cisti, sect. 1 . 2 1 . PRECliE — Lysimachice 34, chiefly sect. 2, and ^art of 3. 22. Caryophylle-ZE — Caryophylkcc $2. 23. TRiriiLATiE — Meliee 7 1 , make the 1st section; Wapindi 65, Aeera 66, and Malpighicc 67, chiefly compose the 2d and 3d sections. Tropccolum is cer- tainly better placed here by Linnaus than in Jussieu's i & crania 73. 24. Con YD ALES — These have no analogy to any particular Order of Jussieu. The Linnaean genera 202 COMPARISON OF THE NATURAL ORDERS are Md'wnthus and Monnieria, for both which see remarks on Jussieu's Ratacece 8 1 ; Epimedium, sec Berberides 78; Hypecoum, and Fumaria, see Papa- veracece 62 ; Leontice, see Berberides 78 ; Impatiens see Gerania 73 ; Utricularia and Pinguieula, see the end of Lysimachice 34. Jussieu's Order of Ber berides 78 entirely escaped Linnaeus. 25. PuT-AMiNE.'iv — Capparides 64, except Oes centia. Linnaeus has noted that this Order and the 24th should stand next to the 27th Rhoeadece. 26. Multisiliqu/E— Ranunculaceaz 61. Seeds inserted into 1 suture only. Linn. MS. 27. Rhoeadete — Papwveraceai 62. Linnaeus has brought hither Nymphaia ; see obs, on Jussieu's Ord. 62. 2&. Luridte — chiefly Solanece 4 1 . Aestivatio plicata. (Corolla plaited in the bud.' Linn. MS. 29. Campanace^ — Campanulacea 52 ; as also Convolvuli 43, and Polemonia 44, both well sepa- rated from the first by Jussieu. Linnaeus has referred Viola to this Order, and has mentioned in manuscript Parnassia, with an exception on account of it's not being milky. 30. Contorts — Apocinccc 47. Aestivatio contorta. (Corolla twisted, or it's seg- ments oblique.) Linn. MS. This author, as well as Jussieu, has committed some errors with regard to OF UNNZEUS WITH THOSE OF JUSS1EU. 203 te tarticular genera. Genipa and Gardenia, both one ft H&us, and Macrocncmum, belong to Jussieu's Ru~ caccce 57. 31. Veprecul/e — Thymelcece 25. Thesium and Santalum, the latter added in manu- t- xript, do not belong to it, but to Mr. Brown's Santa- dcece mentioned under Jussieu's Elceagni 24. Scleran- \kus, also added in manuscript, is referred by Jussieu ie » his Portulacece 86, not without a suspicion of it's re- itionship to his Thymelcece 25, or to Thesium. 32. Papilionaceze — such of the Leguminosce 93, ss have a papilionaceous corolla. 33. Lomentaceje — the restof the Legumi?iosa?93. 34. Cucurbitaceze — Cucurbit acece, 97. 35. Senticos/e — consist of the 2d, 3d and 4th eections of Jussieu's Rosacece 92 ; Poterium and San- uisorba being properly brought hither from Ord. 54. 36. Pomaceje — Sect. 1, with part of the 3d and th sections of Rosacece 92. Ribes is introduced here; «ee Jussieu's Cacti 85. Punica, one of the Linnaean Pomacece, is referred to Myrti 89, by Jussieu, per- laps less correctly. 37. Columniferje — Malvacece 74. Camellia and fdiea are included. See Aurantia 70, sect. 3. 38. TiticocciE — Euphorbia 96. 39. Siliquoste— Cruciferce 63. 40. Persoxat/e — Pedicularcs 35, Acanthi 36, Witices 38, Scrap// ularice 40, and a few of the '.wecc 41. These very distinct Jussieuan Orders were 204 COMPARISON OF THE NATURAL ORDERS probably not discriminated by Linna3us,in consequent*^ of the habit he had acquired of considering his Dicly namla Angiospermia as completely a natural asseni blage. 41. Asperifolle — Borrasinea 42. 42. VERTiciLLATiE — Labiates 39. 43. D VMOsm-*-Rhamm 95 constitute the bulk o this Order ; with one or two Rutacece 8 1 , more o which latter are added in manuscript. Viburnum, Sam bucus and Rhus are also placed here, with some marks of doubt, and Linnaeus ingenuously confesses that he was dissatisfied with the whole. 44. Sepiarle — Iasm'mea 37. 45. Umbellate— Umbellifera 60. 46. HederacEjE — Aralice 59, at least so far as concerns the first two genera,Pdw&r and Aralia. Xan- thoxylon is one of the Rutacece 81. The remainder,! Hedera, Vitis, and Cissus, are proposed in the ma-| nuscript of Linnaeus to be transferred to his 34th Or-[ der, Cucurbit ace ce, but he remarks that their fruit is | not tricapsular, or trilocular. The tendrils and fo- liage may possibly have led to this idea of their affi- nity, which is certainly not tenable on other grounds. 47. Stellatte — Rubiacccc 57, sect. 1 and 2, the remaining sections of Jussieu being faintly indicated by Linnaeus in his sect. (3 and y. The Litter had not detected those characters, even of habit, which unite the shrubby Rubiacece into a very distinct and natural assemblage. OF LINN&US WITH THOSE OF JUSSIEU. 205 48. Aggregate — The two systems do not here ac- nrd, and it is necessary to explain some manuscript [derations of Linnaeus. This Order is divided, in the Hi- een. PL, into four sections. « consists of Statice only : of Hartogia, Brunia, Protect, G lobular ia, Leuca- mdron, Hebenstretia, Selago, Cephalanthus, Dipsa- ns, Scabiosa, Knautia and Alllonia : y of Valeriana. . ITorina, Boerhaavia and Circcea, to which Mirabilis is iilded in manuscript : and £ of Lonicera, Chiococca, riosteum, Mitchella. Lisianthus in manuscript, Lin- rea,Morinda, Conocarpus, Hilliam manuscript, Loran- \ms and Viscum. The letter (3 is removed in the manu- script to Cephalanthus ; so that the 1st section extends com Statice to Selago, inclusive; and is marked 11 alter- j folia infer ce" leaves alternate, flowers inferior(or ger- iden superior). The other three sections, from Cephu- mthus to Viscum, are marked " oppositifolice super w," vaves opposite, flowers superior. The first section rous extended abounds with errors. Statice and Bru- ia indeed, thought near akin by Linnreus, are puz- iing genera, about which various opinions may be )»rmed. Jussieu refers the former to his Plumbagines 3, the latter to his doubtful Rhamni 95. Hartogia ;i the same genus as Diosma, a true Rutacea 81, ^hich Linnaeus subsequently discovered. Protea and , .ueucadendron form the basis of Jussieu's and Brown's rreat Order of Proteacece Q6, not detected by Lin- aaeus, to which Jussieu was inclined to refer Globu- nria ; but he left the latter at the end of his Lysima- 206 COMPARISON OF THE NATURAL ORDERS chice, where surely it is much misplaced. Hebemtretl and Sclago are related to Verbena, see Vitices 38. With respect to the opposite-leaved sections, (3, * and 5; Cephalanthus, Chiocoeca, Mitchella, Morindt and Hillia are well considered by Jussieu as Rubia cecB 57. From Dipsacus to Morhia, inclusive, ar his Dip.sacete 56. Boerhaavia and Mirabilis are Nyc tagines 32. Ciraea is one of the Onagra 88. Lo nicer a, Triosteum, Llnnaa, Lor ant h us and Viscun are Caprifolia 58. Lisianthus belongs undoubtedly : to the Gentiance 46. From the above detail it appears, that there car if hardly be a greater discordance of opinion than exist: I between Linnaeus and Jussieu, concerning the plant; of this Order ; nor can the latter be denied the honoui : of having best, if not perfectly, understood their affi- nities. 49.

AMENTACEiE — Amentacea 99, with an excep- tion or two, such as Sloanea, marked with a doubt by Linnceus, and referred by Jussieu to his Tiliacetf 79 ; and Pistacia, one of the Terebintacecv 94. Cynomo- riwm is placed by Jussieu, with Balanophora of For- ster, t. ,50, among the plant & incertcc sedis. 5 1 . Conifers — Conifera 100, except Equisctum, one of the Filices 5. 52. Coadunatje — Anonte 76, and Magnolice 75. OF LINNiEl'S WITH THOSE OF JUSSIEU. 207 53. Sc A BRIDGE — Uvt'lCtf f)S. Linnajus includes Trophis, which Jussieu did not determine; as also Ulmtis with Celtis, both referred \y the latter, less correctly perhaps, to his Amentacece ,0. Bosea and Acnida are, with more justice, placed if nmong his Atriplices 29- 54. Miscellanea — An Order composed of 8, a- truly miscellaneous, sections, most of them abrogated w the pen of Linnaeus himself. Sect, cm, consisting of Reseda and Datisca, has not undergone any correction. Reseda is referred by Jus- n iieu, somewhat paradoxically, to his Capparides 64; sitnd Datisca, though allowed by him to be, in some joints, akin to the former, stands among the unclassed rfcfenera. (3 Poterium and Sanguisorha, are removed to the J5th Order, before Agrimonia, as they stand in Jus- iiieu's Rosacea 92, sect. 3. y Pistia and Lemna are referred to the 15th hiun- lafee. Jussieu has the former among his Hydrocha- rrides 22, with a hint of it's probable affinity to Aroi- liece 7, or Aristolochice 23 ; and Lemna, one of his VNa'iades 6, is, according to Mr. Brown, one of the Hy~ irocharides. $ Coriaria, and Empctrum with a mark of doubt. EThe first is not thought referable to any Order by IJussieu ; the latter is supposed akin to Ericce 51. s Achy rant hes, Celosia, Amar ant hits, Ireslne, Gom- fyhrena and Phytolacca are all removed to the 5th 208 COMPARISON OF THE NATURAL ORDERS section of the 12th Order, Holeraccce. Jussieu has them all amongst his Amaranth i 30, except Pliyto lacca, which, is one of the Atriplices 29. £ Nymphcea and Sarracenia, are both transferred to the 27th Order, with a query whether the latter especially may not be akin to Asarum, and therefore to the Sarmentacece, Ord. 11. We find that Linnaeus once placed both these genera, as well as Aristolochia, and it's allies Asarum and Cytinus, in his 1 1 th Order. He had a fanciful idea of an affinity between Nyjn- phcea and Sarracenia, founded on the singular eco- nomy of the leaves in the latter. These he supposed to be contrived for the purpose of affording the plant a continual supply of water, which, like it's aquatic relation, it might require. Jussieu but faintly hints at the affinity in question, placing Sarracenia among the plant ce incertce sedis. 7} Cedrela and Swietenia are both removed to the 23d Order, along with Turrcea Linn. Mant. 1.50. They all undoubtedly belong to the 1st section of that Order, being among the Mclice, 71, of Juss. ,9- Tclephium, Limeum and Corrigiola are trans- ferred to the 5th section of the Holer acece, Ord. 12. Jussieu has them all in his Portulaccce 86, on account of their being furnished with petals ; which circum- stance here, as in the instance of his 82d Order com- pared with the 30th, breaks the natural chain of his system. 55.

Concerning 20 of these he afterwards satis- ed himself ; and at least half the rest are now suffi- iently well understood to be referred to their proper places. The following manuscript sketch, of an arrange- ment of the Dicotyledones, left by this great author at the end of his Genera Plant arum, may be thought worthy of preservation. It has undergone many changes and corrections, as might be expected. The me- itations of such a mind cannot but furnish some ideas to others, however incomplete in themselves- Oppositifolm:.

But in the execution of this plan, difficulties immediately arose, especially respecting the Verti- \illatce 42, whose leaves are invariably opposite, and me Asperifolia 41, as regularly furnished with al- 'srnate leaves. Yet these two Orders could not, in any aatural arrangement, be placed asunder. So the Per- )jnatce 40, chiefly opposite-leaved, were necessarily )) be classed near the Luridce 28, and others, with Uternate leaves. It is needless to point out exceptions nnongst other Orders, or tribes of Genera. No discriminating character of his Orders, or Fragments," was ever formed by Linnaeus. On the wntrary, he adverts under almost every one of them, i) the Prcelectiones published by Giseke, to the ano- malies or exceptions which militate against such an tttempt. His judgment, as I have already hinted, is DDnfirmed by the result of the labours of those who aaye undertaken this arduous task ; though the world extremely indebted to them for having, in the face ff such obstacles, entered upon it. The difficulties, ap- aarent contradictions, and various exceptions, which nmbarrass them in the detail of their performance, rre inherent in the organization of the vegetable body, 1 1 which there is throughout no positive or mathema- ' ccal certainty. A few practical observations, illus- ; rative of this truth, may, not altogether unprofitably, fere close the subject. ' Philosophers have attributed to Nature a plastic 212 VARIABLENESS power, by which form and organization are given t< substances apparently homogeneous, and destitute o any particular configuration. Thus the fluid ot" thl, egg changes to an organized animal body ; and thu the blood and lymph, in the stump of an amputate! limb, become occupied with muscles, blood-vessel and nerves, like the corresponding parts of the ani mal frame. Analogous facts, though less evidentl; perceptible, are to be traced, without any uncertainty in the vegetable body. In the latter we may pei haps, even more positively than in animals, satisf ourselves of the influence of particular circumstance' in causing a different organization. Many a plan may be extensively increased by cuttings or by root* for a succession of years, without producing any seedf or even the least rudiments of flowers. But if one.c more of these cuttings or roots should be treated di ferently from the rest, with respect to their allotte portion of water, heat, or nourishment, such may ver probably bear flowers and seeds, as happened b chance to the Solandra at Kew; see Introd. to Botaii} chap. 14. In other words, the same organic matte which, under the influence of certain causes, assume the form of branches and leaves, in different cii en instances becomes flowers and seeds. If we trac this indefinite power of organization a step furthei we perceive that the materials of a perfect flower, d( stined to form seed, are sometimes transformed hit a mutilated or an over-luxuriant one, consisting c T Of OKC A NIDATION. 'J 13 imnultiplied petals only, in the place of the organs es- sential to the propagation of the species; and in certain circumstances, the whole flower itself is replaced by a gemma or bud (26'), when the plant which bears it is t termed viviparous. So with respect to the appropriate organization of ] particular plants. Each species is naturally furnished with flowers, of a determinate structure, having a cer- tain number of stamens and pistils, as well as of divi- sions or parts in their integuments, all which are con- nected together, in an appropriate mode, in every flower. But circumstances sometimes cause an alter- ation, frequently in the comparative number of such parts or divisions, though very rarely in their mode of connexion. Such are accidental variations, which a competent degree of attention and caution in the observer will enable him to guard against. Their study, cautiously pursued, may often throw light on those more perma- nent diversities of structure, which occupy the studies of the profound botanist, and of which I would now attempt somewhat of a comparative view. In general, the aberrations of Nature in plants bear a considerable analogy to her accidental variations, but are, of course, much more diversified and exten- sive. Thus, in tribes very nearly akin, a correspond- ing number in the parts of fructification is found liable to many more exceptions than a similarity of connexion or insertion.

Linn. <2(2, 214 VARIABLENESS some have 10, others 5, stamens; some have 5 others 3 or 2, styles ; in the Ricornes of Linn, is (the Rhododtndra 50, and Ericee 5 J, of Jussieu) thAfl differences between 4 and 5, 8 and 10, or 5 and 10; i\ are so frequent, as to cause great trouble in classing f. these plants, after the Linnsean artificial system. Bu (fl the instance of an inferior germen in Vaccbiium, is a wide and remarkable difference, of extremely rare occurrence, between that genus and it's near relations Menziesia, Erica, Arbutus, &c. In general, variations or diversities of structure have been thought to take place most in the parts of the flow- er, and especially in those accessory, rather than essen- tial, organs, the calyx and corolla. The production of the fruit and seed, especially of the lacter, being the main object of all the rest, many botanists have, rea- sonably enough, concluded, that the peculiar organiza- tion, and even the number of parts, in the seed-vessel, and, above all, the form and number of the *eeds, were likely to furnish indications of the most important and invariable principles of affinity or distinction Even the diversities in the internal parts, or materials, of a seed, have of late been laid under contribution, for the purposes of methodical arrangement ; as appears from the foregoing explanations of different botanical systems. As far as regards the comparative number of seeds, the slightest observation will teach any person, that Nature has not always made this circumstance of OF ORGANIZATION. ' 215 "'•{importance, in the indication of natural affinities. The thing itself is often indeterminate, several ru- diments of seeds being frequently provided, though >i>nly one regularly comes to perfection. More fre- quently are observable plants with numerous seeds in u cell, or capsule, which are nearly, or very closely, tallied to others with only 1 or 2. See the Onagrce 88, Dof Jussieu, the Cruciferte 63, the genus Juncus, and imany besides. The provision of seed to each vege- iable is indeed of the last importance ; but the quan- tity is, comparatively, immaterial, variable, or pre- carious. It seems therefore that number, as a prin- ciple of arrangement, may well be expected to prove iroore treacherous here than in other cases. The nourishment of a seed, in the first stages of germination, depending generally on the albumen, in whatever form or state that substance may exist, is wariously conducted, according to circumstances, in plants otherwise nearly allied ; witness the papiliona- ceous family, where the albuminous matter is lodged in cotyledons, that in some species rise into seminal leaves, in others decay speedily under ground. In ^some plants, as we have seen, the albumen is evident in a distinct and separate form ; while in others, nearly akin, no such substance exists, except, as must be presumed, in the body of each cotyledon. Here again therefore, however essential the part in question, the mode of it's existence appears to be of very sub- ordinate consideration, and should not be allowed, in 216 A1 TINITY 01 BEGONIA. the details of systematic arrangement, to overrule characters which are judged, by experience or analogy, to be more important. The able writers whose la- bours we have been contemplating, the chief syste- matic botanists who have adverted at all to the albu- men, have been well aware of this. What has just been remarked, of the inconstancy of number in the seeds of particular plants, and of it's great diversity in species or genera nearly akin may possibly diminish the apparent absurdity of con sidering the great differences between the fruit of Be gonia and Polygonum or Rumex, and between that o some CampanulacecB and the Composite, as a matte of but secondary importance, and may reconcile us t the opinion that such differences should give way, ii both cases, to strong points of agreement. Even th great distinction between the inferior germen of Be gonia, and the superior one of the Order of Polygo nece, Juss. 28, is invalidated by the above instance o Vaccinium; and the coincidence of habit is so remark able, that I cannot but confess myself very anxious t ascertain a decisive affinity, or analogy, in the fructi fication, lest the great fundamental principle of sound botanical classification should, in any degree be undermined.
