PREFACE.

WHEN the first edition of this work was issued, some
portions of the country embraced within the limits assigned
to it were imperfectly investigated or wholly unexpiored.
But the discoveries in Southern botany made during the
last few years by Feay, Garber, Curtiss, and others, of
tropical forms on the peninsula and keys of Florida, by
Dr. Gattinger of Northern forms which extend into Ten-
nessee and the mountains of North Carolina, and by cor-.
respondents from other States, have become so numerous
that a new edition of the Southern Flora is required to
embrace them. |

In this edition I have concluded to incorporate these
additions in the form of a Supplement to the first edition,
avoiding any material alterations in it.

And now, since the different sections of all the States
which are included in the limits embraced by this work
have been pretty thoroughly explored, and future acqui-
sitions will, probably, be comparatively few in number,
the time seems to have arrived when the promise pro-
visionally made in the Preface to the first edition may be
at least partially fulfilled. ie

vi PREFACE.

It is my intention, therefore, to commence the prepara-
tion of a final edition, which shall include in their proper
place all the acquisitions made to our Flora since the
publication of the first edition, with the changes in no-
menclature introduced during that time; and I invite
a continuance of the co-operation and assistance of all
who are interested in the successful prosecution of the
work.

INTRODUCTION.

L SKETCH OF THE ELEMENTS OF BOTANY.

1. Vegetable Tissue.

_1. Pxants are primarily composed of minute membranous vesicles or cells,
which are endowed with the power of reproduction, and through which, al-
though closed and destitute of visible pores or openings, the juices of the plant
are readily transmitted.

2. Variously modified, these cells form the Elementary Tissues ; viz. Cellular
Tissue or Parenchyma, Woody Tissue or Woody Fibre, and Vascular Tissue or
Vessels and Ducts.

3. Cellular Tissue, which exists in all plants, and of which those of the lower
orders are wholly composed, consists of cells aggregated together, and cohering
by their contiguous surfaces.

4. Woody Tissue is composed of slender and elongated cells, with firm and
thickish walls, collected in threads or bundles.

5. Vascular Tissue is made up of larger cells, either in the form of continuous
tubes, or forming such by the union of their extremities. In some of these, the
walls are marked with dots, lines, or bands; while in others they are lined with
spirally coiled fibres which are capable of being unrolled. The latter are called
Spiral Vessels, and exist only in plants which bear proper flowers.

6. Of these tissues are formed the Organs of plants; viz. Organs of Vegetation,
consisting of the Root, Stem, and Leaves, and Organs of Reproduction, consisting
of the Flower and Fruit.

2. The Root.

7. The Root, or Descending Azis, is that part of the plant which grows down-
ward, commonly penetrating the soil, from the moisture of which it imbibes
nourishment. It branches indefinitely and without order, but bears no other
appendages. Its ultimate branches are called Roollets.

8. Roots which descend immediately from the embryo are termed Primary
Roots. They are called Tap-Roots, when they consist of one thick and fleshy
piece ; fascicled or clustered, when of several fleshy branches springing from a
common centre ; tuberous when the branches become greatly enlarged and filled
with starchy matter; and jibrous, when all the parts are slender and thread-like.

x INTRODUCTION.

9. But roots under favorable circumstances are developed from other parts of
the plant. These are called Secondary Roots. a

10. Aerial Roots are those which spring from the stem or branches above
ground. In some, as in many Endogenous Plants, they proceed from the lower
joints of the stem; in others, as the Mangroves and Fig-trees of South Florida,
they descend from the branches, and at length, penctrating the soil, form new
stems in all respects similar to that of the parent tree. The tendril-like roots of
some climbing stems are also of this class.

11. Epiphytes or Air-Plants, of which the Tillandsia and Epidendrum are ex-
amples, are those which are borne on the trunks or branches of trees, but draw
their nourishment from the air. .

12. Parasites, like Air-Plants, grow on other plants; but their roots, pene-
trating the substance of the supporting plant, feed upon its juices. Some, as
the Mistletoe and Dodder, fix themselves upon the trunk or branches ; others,
like the Beech-drop, upon the root.

3. The Stem.

13. The Stem, or Ascending Axis, is that part of the plant which grows up-
ward into the air and light, bearing leaves and flowers. It exists, under various
modifications, in all flowering plants ; but in those which are said to be steml/ess
or acaulescent, it is very short, or concealed in the ground.

14. It consists of a succession of leaf-bearing points, or Nodes, ipl by
naked joints, or Znternodes. The growing points, which are protected by reduced
leaves in the form of scales, are called Buds. 'These are terminal, when they ter-
minate the axis; axillary, when they spring from the axil of the leaves; that is,
from the point where the upper surface of the leaf joins the stem; and adventi-
tious, when they are developed from any other part.

15. Simple stems grow by the development of the terminal bud alone ; branch-
ing stems expand indefinitely from the axillary buds also. The ultimate divis-
ions of the branches are called branchiets.

16. The jointed stem of Grasses and similar plants is a Culm.

17. The thick and simple stem of the Palmetto is a Caudez.

18. A Rhizoma, or Rootstock, is a perennial stem, commonly creeping on the
ground, or beneath its surface, developing annually a bud at the apex, while
the older portion decays.

19. A Tuber is a subterranean branch, excessively thickened by the deposition
of starchy matter, and furnished with minute scales, having concealed buds (eyes)
in their axils.

20. A Corm is a solid globular subterranean stem, filled with starchy matter,
with a bud at the apex and roots below.

21. A Bulb is a short subterranean stem, made up of the thickened bases of
leaves, in the form of persistent scales. It is tunicated or coated, when the scales
are large and wrapped one within the other; and sca/y, when these are small
and imbricated. Small aerial bulbs, such as are borne in the axil of the leaves
of the Tiger-Lily, and among the flowers of the Onion, are called Bulblets.

22. A Stolon is a branch which bends to the earth, strikes root, and forms a
new plant.

Se

ELEMENTS OF BOTANY. x1

23. A Runner is a thread-like prostrate branch, producing roots and a tuft of
leaves at its extremity

24. Spines, or Thorns, are imperfectly developed, leafless branches, with hard
tips. .

25. Tendrils are the thread-like spirally coiled branches of weak and slender
plants, by means of which they attach themselves to other and stronger objects
for support. Leaf-stalks and parts of the inflorescence are occasionally convert-
ed into tendrils.

26. Plants which die down to the ground at the close of the season, or after
maturing seed, are called Herbs, or Herbaceous Plants. Those with woody stems,
lasting from year to year, when of humble size, are called Shrubs, and when
reaching an elevation of twenty feet or more, Trees.

4. Internal Structure of Stems.

27. The stems of Phenogamous Plants are composed of cellular tissue, woody
tissue, and vessels; and upon the arrangement of the latter are founded the two
divisions of Exogenous and Endogenous Plants.

28. Exogenous stems consist of a central column, called the Pith ; an external
covering, called the Bark; and a middle portion, called the Wood.

29. Their Pith is a mass of cellular tissue, enclosed in a thin sheath of spiral
vessels, termed the Medullary Sheath.

30. Their Wood is composed of one or more layers of woody and vascular
tissue, traversed by thin plates of cellular tissue, called the medullary rays, and
annually increased, in all perennial stems, by the addition of a new layer to the
outside of that of the previous year. The new wood is called the Alburnum, or
Suap-wood, and the older and harder portion, the Duramen, or Heart-wood.

31. The Bark, like the wood, is made up of layers. The inner bark, or Liber,
is composed chiefly of woody fibre. Between it and the wood, in the growing
season, is secreted a thin mucilage, called the Cambium, in which the new layers
of wood and bark are developed. Surrounding the inner bark is the Green bark,
consisting of cellular tissue filled with Chlorophyll, or the green matter of veg-
etables. Covering the whole is a thin membrane of cellular tissue, called the
Epidermis, or Cuticle.

32. Endogenous stems exhibit no distinction of pith, wood, and bark; but
are composed of threads or bundles of woody tissue, irregularly embedded in
cellular tissue. They increase in diameter by the formation of new bundles,
which are chiefly directed to the centre of the stem.

5. The Leaves.

33. Leaves are expanded appendages of the stem, developed from axillary
and terminal buds. They consist of loose cellular tissue, supported by a net-
work of woody and vascular tissue, called veins or ribs, and protected by the
epidermis. In them the fluids received from the root, and what they imbibe
from the air, through minute openings in the epidermis, called stomata, are con-
verted into the proper food of the plant.

34. In the bud, they are folded, plaited, or coiled in various ways. This is
termed their Vernation.

INTRODUCTION,

but these three parts are not always present in one leaf.

36. The Blade,-Limb, or Lamina, is the expanded part, and enn a eat

variety of forms. It is simple, when it consists of a single piece, however cut or —
divided ; and compound, when of two or more distinct pieces (leaflets), which
separate by a joint.

37. The Stalk, or Petiole, connects the blade with the stem. When it is
wanting, the leaf is said to be sessile. The stalk of a leaflet is called a Petiolule.

38. The Stipules are appendages of various forms, placed one on each side at
the base of the petiole. They are separate, or else united with the petiole, or
with each other, when they occasionally form a sheath (Ochrea) around the
stem above. The stipules of a leaflet are called Stipels.

39. The manner in Hans the veins are distributed through the leaf is called
Venation.

40. There are two modes of venation; viz. parallel-veined, or nerved, when
several simple veins, or ribs, run parallel from the base of the blade to its apex ;
and reticulated, or netted-veined, when the veins divide into numerous primary and
secondary branches (veinlets), which again unite to form a kind of network.

41. The latter mode embraces both the pinnately veined, or feather-veined leaf,
where the petiole is continued through the middle of the blade, giving off at in-
tervals lateral veins; and the palmately veined or ribbed leaf, when it divides at
the apex into three or more strong branches.

42. The manner in which leaves are divided corresponds with that of their |

venation.

43. A simple pinnately veined leaf becomes pinnatifid, when the incisions
(sinuses) extend about half-way to the midrib, or continuation of the petiole;
and pinnately divided, when they extend down to the midrib. A compound pin-
nately veined leaf is, of course, pinnate, with the separate leaflets arranged on
each side of the common petiole. When this is terminated by a leaflet, the leaf
is said to be odd-pinnate, or unequally pinnate, and when it is wanting, abruptly
pinnate.

44. So, also, the palmately veined leaf becomes palmately cleft or divided,

when the incisions are directed toward the base of the blade. When the divis-

ions consist of separate leaflets, it becomes palmately compound.
45. Floral leaves, or those from the axils of which the flowers are developed,
are called Bracts; and those which are borne on the flower-stalk, Bractlets.

6. The Flower.

46. A Flower consists of those parts, or organs, which are concerned in the
production of seed. Like the leaf, of which its parts are a modification, it is
developed from an axillary or terminal bud.

47. The manner in which the flowers are arranged on the stem or branches is
termed the /nflorescence.

48. There are two modes of inflorescence ; viz. the indefinite, or centripetal,

where the flowers all arise from axillary buds, the lowest or outermost expand-
ing first, while the axis elongates indefinitely from the terminal bud; and the
definite, or centrifugal, where the flowers arise from the terminal bud, first, of the
main axis, and successively from that of the branches.

35. A complete leaf comprises the Blade, the Stalk, and a pair of S Stipule ' 7

49. When the flowers arise from the axil of the ordinary leaves of the stem,
they are said to be avilary; but oftener, they are disposed in a more or less
obvious cluster, each arising from the axil of a greatly reduced leaf, or Bract.

50. The stalk of a solitary flower, or of a cluster of flowers, is termed the
Peduncle; or, when it proceeds from the root, a Scape; and that of each indi-
vidual of a cluster is called a Pedicel. The main axis of a cluster, or that
portion of the common peduncle which bears the flowers, is called the Rachis.

51. The indefinite inflorescence includes the Spike, Ament, Spadix, Raceme.
Corymb, Umbel, Head, and Panicle ; the definite, the Cyme and its modifications.

52. The Spike consists of a more or less elongated rachis, with the flowers
sessile, or nearly so, in the axils of the bracts.

53. The Ament, or Catkin, is the scaly deciduous spike of the Pine and
Willow.

54. The Spadix is a spike with the flowers borne on a thick and fleshy rachis.
Tt is naked, as in the Golden-club, or enclosed in a hood, called the Spathe, as in
the Indian Turnip.

55. The Raceme presents the elongated rachis of the spike, but the flowers
are raised on pedicels.

56. The Corymb is a short raceme, with the lower pedicels elongated, so as to
bring their flowers to the same level as the upper ones.

57. The Umbel is a modification of the raceme, but with the rachis so much
contracted, that the pedicels (rays) apparently spring from a common centre.
When the umbel is compound, the partial umbels are termed Umbellets.

58. A Head is an umbel with sessile flowers. The crowded bracts of this and
the preceding are collectively termed the Jnrolucre, and those of the umbellets,
the Involucel.

59. When the pedicels of a raceme or corymb are transformed into branches,
either simple or successively divided, the inflorescence becomes a Panicle.

60. When the further growth of the axis is arrested by a single terminal
flower, and from the axils below branches are developed, each terminated by a
flower, and bearing branches in the same manner, the inflorescence is said to be
cymose or centrifugal. But it presents several peculiar forms, occasioned either
by the imperfect development, or by the entire suppression of some of its parts.
Some, as the true Cyme, are short and expanded ; others are elongated, like the
spike or raceme. In all, the flowers expand successively from the summit,
downward, or from the centre, outward.

61. The Flower consists, commonly, of one or more whorls of leaves, called
the Floral Envelopes, — of which the outer one is termed the Calyx, and the inner
one the Corolla, —an inner whorl of thread-like organs, called the Stamens, and
one or more central organs, called the Pisti/s. These are inserted on the apex
of the axis, which here takes the name of Torus, or Receptacle.

62. The Floral Envelopes are sometimes wanting ; but the stamens and pis-
tils, being the fertilizing organs, are, in all perfect flowers, always present.

63. The Calyx is composed of leaves (Sepals). usually of a greenish color,
which are distinct, or united by their margins. When the floral envelopes con:
sist of a single whorl only, it is always a calyx.

b

xiv INTRODUCTION. Ce

64. The Corolla is usually of a thinner texture than the calyx, and variously
colored. Its leaves (Petals), when of the same number as the sepals, always
alternate with them. They are also often united by their contiguous margins, to
form a monopetalous corolla.

65. When the calyx and corolla are so nearly alike as not to be readily dis-
tinguished, they are collectively termed the Perianth.

66. A flower is complete when all its parts are present ; incomplete, when the
floral envelopes, or a part of them, are wanting ; perfect, when the stamens and
pistils are borne in the same flower ; imperfect, or diclinous, when they are borne
in separate flowers ; regular, when the sepals or petals are of uniform shape and
size; and irregular, when they are unlike in shape or size.

67. Imperfect flowers are further distinguished into monecious, when those fur-
nished with stamens (stfaminate or sterile flowers) and those furnished with pistils
( pistillate or fertile flowers) are borne on the same plant; diwcious, when they are
borne on separate plants ; and polygamous, when both perfect and imperfect flow-
ers are borne on the same or different individuals.

68. The manner in which the parts of the floral envelopes are arranged with
respect to each other in the bud is termed their /stivatiuon. They are valvate,
when their contiguous margins meet, without overlapping; induplicate, when
these project inwardly ; reduplicate, when they project outwardly ; imbricated,
when the margins of one overlap the adjacent margins of the two next within ;
convolute, or twisted, when one edge of each piece covers the margin. of the one
next before it, and the other edge is covered by the margin of the one next after
it; and plaited, when the parts are folded lengthwise.

7 The Stamens.

69. A Stamen consists of a sac, called the Anther, and, usually, a stalk, called
the Filament, by which it is supported.

70. They are hypogynous, when they are inserted on the receptacle ; perigynous,
when on the calyx; epigynous, when on the ovary; epipetalous, when on the co-
rolla; and gynandrous, when they are united with the style. They are, also,
often combined with each other, either into one set (monadelphous), or into two,
three, or more sets (diadelphous, triade/phous, &c.).

71. The Anther is composed, commonly, of two united cells, which open in
various ways, and discharge a yellow, fertilizing powder, called the Pollen. The
part which connects the cells is the Connective.

72. It is erect, or innate, when fixed by its base to the apex of the filament ;
adnate, when fixed to the filament by its whole length; versatile, when fixed by
the middle to the apex of the filaments on which it turns as on a pivot; introrse,
when it faces inwardly toward the pistils; and eztrorse, when it faces outwardly

toward the petals. Occasionally, they are united into a tube (syngenesious). ~ ;
73. Between the stamens and the pistils is often a fleshy expansion, called the

Disk. ,
8. The Pistils.

74. The Pistils occupy the centre of the flower. They are inserted, singly or —
in a whorl, on the receptacle; or, when this is elongated or enlarged, they cover

its surface.

ELEMENTS OF BOTANY. xv

75. A Pistil consists of three parts, —the Ovary, the Style, and the Stigma.

76. The Ovary is the lower and hollow portion, containing the Ovules, or ru-
diments of seeds.

77. The Style is an extension of the ovary, commonly of its apex, which sup-
ports the stigma.

78. The Stigma is commonly the apex of the style, or, when this is wanting,
of the ovary, denuded of the epidermis.

79. When the pistil is composed of a single piece, or carpel, it is simple; but,
oftener, it is compound, consisting of two or more carpels, united by their margins,
or by their sides, which then form partitions or dissepiments, that divide the pistil
into as many cells as there are carpels.

80. The line next the axis, or which corresponds to the united margins of a
folded leaf, is called the Ventral Suture; and that which corresponds to the mid-
rib, the Dorsal Suture.

81. The Ventral Suture bears the ovules; and the line of their attachment is.
called the Placenta. This is central or axile, when it occupies the centre of the
pistil, and parietal, when it is borne on its walls.

82. The Ovule is connected with the placenta by a cord, called the Funiculus.
It consists of a central body, called the Nucleus, enclosed in two sacs, each with
an opening at the apex, called the Foramen. The outer sac is termed the Primine,
and the inner one the Secundine. The point where these parts unite is called the
Chalaza.

83. The Ovule is orthotropous when the chalaza is next the placenta, and the
apex at the opposite extremity ; campylotropous, when it curves on itself, so as to
bring the apex near the chalaza; anatropous, when it is inverted on its cord, to
which it adheres; the true apex pointing to the placenta, while the chalaza, or
true base, points in an opposite direction ; and amphitropous, when it is half in-
verted on its cord, its axis running parallel with the placenta. The adhering
portion of the cord in the last two cases is termed the Raphe.

9. The Fruit.

84. The Fruit is the ovary, with its contents, brought to maturity. But dur-
ing this process it sometimes undergoes important changes, either by the obliter-
ation or abortion of some of its cells, partitions, or ovules, or by the formation of
false partitions, or by various changes effected in its walls, or in the parts which
surround them.

85. In some, the walls, or Pericurp, remain closed; in others, they open, or
are dehiscent in various ways, oftener splitting regularly into separate pieces,
called Valves.

86. Many terms are employed to designate the different kinds of fruit, but only
the following are in general use.

87. A Follicle is a simple fruit, opening along the ventral suture only ; as the
fruit of the Milkweed.

88. A Legume is asimple fruit opening at both sutures; as in the Pulse Fam-
ily. When it is divided across into closed joints, it is a Loment.

89. A Capsule is a dry compound fruit, opening in various ways. When it
opens at the dorsal sutures, or into the cells, the dehiscence is said to be loculicidal ;

xvi : INTRODUCTION.

ti
and septicidal, when it opens at the ventral suture, or through the partitions.

When it opens transversely, the upper portion falling off entire, like a lid, the
dehiscence is circumscissile. at

90. A Silique is a slender two-valved capsule, with two parietal placentze con-
nected by a persistent false partition. A short and broad silique is a Silicle.
These are peculiar to the Mustard Family.

91. A Pepo is the fleshy indehiscent fruit of the Gara Family, with the seeds
often embedded in the pulpy placente.

92. A Pome is the indehiscent fruit of the Apple or Quince tribe, where the —

cells are enclosed in the enlarged and fleshy tube of the calyx.

93. A Berry is an indehiscent fruit, with the seeds embedded in soft pulp.

94. A Drupe consists of one or more hard or bony cells, called the Puta-
men, covered with a fleshy or pulpy coat, called the Sarcocarp; as the Peach,
Holly, &e.

95. An Achenium is a small, dry, one-seeded, indehiscent fruit, the walls of
which do not adhere to the enclosed seed. When these are closely united, it
becomes a Caryopsis; or when the walls are thin and bladder-like, and open
irregularly, a Utricle.

96. A Nut is a dry, indehiscent fruit, with hard or bony walls; as the Acorn
and Hickory-nut. :

97. A Samara is a dry, indehiscent fruit, with its walls expanded into a wing ;
as that of the Maple and Elm. °

98. The collective fruit of the Pine is called a Cone or Strobile.

10. The Seed.

99. The Seed is the matured ovule, and contains the Embryo, or the rudiment
of a future plant. The outer coat, or Jntegument, is called the Testa. It varies

!

greatly in texture, and is occasionally furnished with hairs, which either cover the

entire seed, or form a tuft (Coma) at one or both extremities.

100. The terms employed in describing the ovule are chiefly applicable to the
seed. The foramen of the ovule, which is closed in the seed, becomes the Jh-
cropyle, and is always opposite the radicle of the embryo. The scar left on the
seed by the separation of the cord is the Hilum. It is sometimes enveloped in
a false covering, originating, during its growth, from the cord or from the pla-
centa. This is called the Aril.

101. The Testa includes either the embryo alone, or an additional nutritive
substance, called the Albumen.

102. The Embryo consists of the Radicle, the Plumule, and the Coyle

103. The Radicle is the first joint of the stem. In germination, it elongates
at one end to form the root, and at the other, from a minute bud (Plunule), to
form the stem. It is inferior when it points to the base of the pericarp, and su-

perior when it points to its summit.
104. The Cotyledons are the seed-leaves. The embryo of the Exogenous

Plants bears two of these, placed opposite (rarely three or more in a whorl),

while that of Endogenous Plants bears only one. Hence the former are called

dicotyledonous, and the latter monocotyledonous.
105. When the embryo is exposed to the combined influence of air, heat, and

moisture, it develops into a growing plant. This is termed Germination.

ELEMENTS OF BOTANY. Xvii

106. The preceding considerations refer solely to Phzenogamous Plants, or
those which bear flowers, consisting of stamens and pistils, and produce seeds,
which contain an embryo, or a rudiment of a future plant.

107. But there are plants of a lower grade, which do not bear flowers furnished
with ordinary stamens and pistils, nor seeds containing an embryo, but in place
of seeds they produce minute powdery bodies, called Spores. These are termed

11. Cryptogamous or Flowerless Plants.

108. The stems of the higher orders of Cryptogamous Plants — and these only
are embraced in this work — exhibit nearly the same anatomical structure as
those of Phenogamous Plants. But they grow only from the apex, without any
perceptible increase of diameter, and therefore are termed Acrogens or Point-
growers.

109 The different orders presenting no common type, the habit, the mode of
inflorescence, and the process of fertilization, so far as it is known, being different
in all of them, the characteristics of each are more conveniently explained in the
body of the work, and need not be enumerated here.

12. Classification.

110. Classification consists in the arranging of plants possessing like structure,
habits, &c., into groups, designating them by proper names, and defining them
by appropriate characters.

111. An assemblage of individuals which are so essentially alike as to indicate
their descent from a common parent, and which preserve their characteristics
when propagated from seed, is termed a Species. But circumstances connected
with the growth ofan individual may produce some deviation from its ordinary
state, and it then becomes a Variety.

112. When the pistil of one species is fertilized by the pollen of another allied
species, the result is a Hybrid.

113. An assemblage of species agreeing with one another in structure and ap-
pearance constitutes a Genus. In the same manner, although with fewer points
of agreement, genera are collected into Orders, or Fumilies, and these, in turn, into
Classes.

114. But each of these may include members that agree in some important
points, which are not common to the others. Of such are formed the intermedi-
ate divisions of Subgenera, Suborders, and Subclasses.

115. There are two modes or systems of classification; the Artificial System
of Linnzus, and the Natural System of Jussieu.

116. In the Artificial System, the Classes and Orders are founded on the num-
ber, position, and connection of the stamens and pistils, regardless of any other
relationship. In the Natural System, every part of the plant is taken into consid-
eration ; and the Orders embrace those genera which agree with each other in the
greatest number of important particulars. The latter system is now in almost
universal use, and is the one adopted in this work.

VY. DIRECTIONS TO THE STUDENT.

Havine acquired a general knowledge of the principles of botany, and of the
meaning of the peculiar terms employed in the science, the student proceeds to
study or analyze plants, with a view to determine their names, and the place they
occupy in the system.

His chief difficulty, at the outset, will be to ascertain to which one of the 164
natural orders or families contained in this work the plant he may have in hand
belongs. Were he to attempt to compare it with the characters of each order
successively, the task would be tedious and discouraging.

To obviate this, and to enable him to refer any unknown plant directly to its
proper place in the Flora, some guide, such as is supplied by the following An-
alysis of the Natural Orders, will be necessary. One or two examples will best
explain its use.

Suppose we have in hand a flowering branch of the Linden-Tree or Bass-
wood. Turning to the Analysis on page xxix., we compare it, first, with the
Series of Pa#xnoGamous Puants, with which we find it to agree in having
flowers.

Then, dividing the branch across, we see if it is made up of pith, wood, and
bark ; if the leaves are netted-veined ; and if the floral envelopes are in fours
or fives. Exhibiting these peculiarities, it doubtless belongs to the Criass oF
DicotyLeponovs Prants; although, in consequence of the minuteness of the
seed, we have not been able to ascertain the number of the cotyledons.

We next see if the ovules are contained in an ovary. This being clearly the
case, it comes under the Supciass of ANG1ospeRMOUS PLants. The double
floral envelopes, and the separate petals of the corolla, carry it to the PotyPer-
ALOous Division.

Our attention is next directed to the insertion of the stamens and petals, —
whether on the calyx, or hypogynous. In our plant they are hypogynous.
Then, if the stamens are more than twice as many as the petals. They are so
in ours. Then, if the leaves are opposite or alternate. In ours they are alter-
nate. Then, if the ovaries are more than one, or solitary and 1-celled, or soli-
tary and 2-many-celled. In ours they are solitary and 5-celled; bringing it
ander the last alternative. Then, if the stamens are in any way connected

XXViii INTRODUCTION.

with the petals, or free from them. In ours they are free. Lastly, whether
they are united into a tube, or in clusters, or are all separate. In ours they are
¢re united in five clusters, and the sepals are deciduous. ‘This brings our plant
to the natural order, T1L1acka, 59,— the number referring to the page of the
Flora where the order is described.

Turning to that page, and comparing our plant with the character of the
order, we notice their agreement.

We then proceed to find the name of the genus. This is readily done, in this
instance, by comparing the plant with the two genera comprised in this order.
With the first it will be found to agree in every particular, and therefore we
need not carry it further. We find, then, the plant in question to be a species
of the genus Tix1a, so named by Tournefort, and commonly called Linden or
Basswood.

Again, suppose the plant under consideration to be the common Bear-Grass.
Having flowers, it is, of course, Phenogamous. But, cutting across the stem, we
find, in the place of pith, wood, and bark, a white mass of cellular tissue, stud-

ded with minute points, which are the ends of the divided threads of woody -

fibre ; the veins of the leaf run parallel from the base to the apex ; the floral
envelopes are in two rows of three each ; and the embryo, if examined, will be
found to have but one cotyledon. In these respects, our plant differs widely
from the Class of Dicotyledonous Plants, and we therefore turn to its alterna-
tive, the Ctass of MonocoryLeponous PLANTS, on page xxxvii. of the Anal-
ysis, which, we observe, includes plants possessing these characters.

Our plant, having the floral envelopes double, and not glumaccous, falls
under the second heading, marked with two stars ( * * ).

Proceeding as in the former example, and carefully comparing the plant with
the analysis that follows, we see, first, if the ovary is adherent with, or free from,
the perianth. In ours it is free. Then, if the perianth is single, or double. In
ours it is double. Then, if the calyx and corolla are alike or unlike. In ours
they are alike. Then, if the leaves of the perianth are glume-like, or otherwise.
In ours they are not glume-like. Then, if the leaves are netted-veined or par-
allel-veined. In ours they are parallel-veined. Then, if the capsule is 1-celled,
or 3—6-celled. In ours it is 6-celled. Lastly, if the anthers are introrse or ex-
trorse In ours they are introrse.

This.brings us to the natural order Litrace», Aedéribad on page 480 of the
Flora. It contains ten genera, belonging to three tribes, the characters of which
are briefly given in the Synopsis. Our plant, by its capsular fruit, the separate
divisions of the perianth, and leafy stem, comes under the third tribe, TuLrpa-
cem. Of the two sections, marked with a star ( ¥ ), our plant belongs to the
second ; having a Palm-like stem. No. 10, Yucea, alone remains; and to it
our plant must belong.

Turning to page 485, where this genus is more fully described, we find it to
embrace four species, divided into two sections based upon the character of the
stem and capsule. The short stem (excluding the scape) and dry capsule of
our plant belong to the former. It contains but one species. Y. filamentosa, L.,
which we therefore find to be the botanical name of the plant, in question.
