District of Connecticut, ss. 
BE IT REMEMBERED ; That on the thirteenth 
day of January, in the forty-first year of the independ- 
ence of the United States of America, Hezekiah Howe, 
of the said District, hath deposited in this office the title 
of a Book, the right whereof he claims as Proprietor, in the words 
following, to wit ; 

" A Botanical Dictionary, being a translation from the French of 
Louis-Claude Richard, Professor of Botany at the Medical School 
in Paris ; icith additions from Martin, Smith, Milne, Willdenow, 
.icharius, &c." 

In conformity to the Act of the Congress of the United States, en- 
titled, " An Act for the encouragement of learning, by securing 
the copies of Maps, Charts, and Books, to the authors and proprie- 
tors of such copies, during the times therein mentioned." 


Clerk of the District of Connecticut- 

A true copy of Record, examined and Sealed by me, 

Clerk of the District of Connecticut. 






Although this Dictionary has not received the benefit 
of any corrections immediately from your hand, I have 
been governed by your opinions in all cases of doubt. 

Your liberal explanations in answer to my numerous in 
quiries, together with free access to your extensive libra- 
ry, have left me almost without excuse for my errors. 

I beg permission to place the work under your protec- 
tion ; with the hope that my strenuous exertions to exe- 
cute it in an acceptable manner will be received as an 
apology for its defects. 

I am, with gratitude and esteem, 

Your obedient humble servant, 


New-Haven, Sept. 16, 1816. 


In a book like this, where its usefulness depends whol- 
ly on the faithfulness with which the opinions of others 
are given, it is desirable to know from what authorities 
and by what course of proceeding it was compiled. 

1. The terms contained in Richard's Bulliard, and not 
in Martyn's Language of Botany, were interlined in the 
open spaces, or inserted in the broad margin of Martyn, 
with their definitions as translated from Richard. When 
there was not sufficient room, slips of paper were attach- 
ed. Then the definitions of the terms common to both 
authors were made, principally from Richard, and insert- 
ed as before. 

2. All the terms and definitions in Willdenow's Princi- 
ples of Botany were compared with the above, and addi- 
tions and corrections made. 

3. All the terms and definitions in Smith's Elements of 
Botany were compared, and additions made from that 

4. Milne's Botanical Dictionary was then compared 
with the compilation throughout ; and such additions 
were made from it, as were admissible upon the plan of 
this work. 

5. To all this was added the new nomenclature of Li- 
chens by Professor Acharius, as translated by President 
Smith of London. All the modern terms of Willdenow, 
Persoon, and others, relating to Cryptogamous plants,, 
were also inserted in their proper places. 



6. All these materials thus combined, were then co 
pied for the press, with occasional remarks, from the 
hint9 of able botanists. 

Notwithstanding the diminutive size of the book, the 
author almost ventures to hope, that all the terms used 
by botanical writers in Latin or English, who follow the 
Linnean System, will be found here satisfactorily defined 
and illustrated. 



The first edition having been favorably received by 
the public, no essential alterations have been made. The 
Systematic Terminology has been enlarged, by including 
the substance of a pamphlet, entitled, " First Lessons in 
Botany," compiled by Mr. Edwin James of Albany. The 
new terms introduced by Nuttall, Barton, and some others, 
have been carefully denned and arranged in their proper 

The improvement, which will be most valued, is the 
accentuation. For this the reader is indebted to Dr. 
Amatus Robbins, Corresponding Secretary of the Troy 
Lyceum of Natural History, and late Tutor in William's 
College. Perhaps no botanist in our country is more 
competent to perform this great desideratum. 

N. B. When the accent is annexed to a vowel, it is 
to be pronounced long ; but when it is annexed to a con- 
sonant, the accented syllable is to be pronounced short. 

Albany, Feb. 11, 1819. 


The principal elementary terms, together with the 
Classes and Orders, should be fixed in the memory, 
previous to entering upon the exercises of a practical 
botanist. The student must therefore be directed to 
commit to memory the definitions of the following 
terms, according to this arrangement. All other terms 
may be looked out occasionally. 

Every plant is either Phenogamous, or Crypto- 

Phenogamous plants have their stamens and pistils 
sufficiently manifest for examination. 

Cryptogamous plants either lose the staminate 
organs before they become manifest, or they are 
too minute for inspection. 

The Classes, Orders, and Genera of the Linnean' 
system, are founded wholly on the seven elementa- 
ry organs of fructification. 

These are, 
t. Calyx. The outer or lower part of the flower, 

generally not coloured*. 

2. Corol. The coloured blossom, within or above 
the calyx. 

3. Stamens. The mealy or gluttinous knobs, gene- 
rally on the ends of filamentous organs. 

* In the language of Botany, any part of a plant is not colour- 
ed when it is green ; as the calyx of the apple is said not to be co- 
loured, because it is green ; and that of the nasturtion is coloured, 
'■■ecause it is not green. 


4. Pistil, The central organ of the flower, whose 
base becomes the pericarp and seed. 

5. Pericarp. The covering of the seed, whether 
pod, shell, bag, or pulpy substance. 

6. Seed. The essential part containing the rudi- 
ment of a new plant. 

7. Receptacle. The base which sustains the other 
six parts, being at the end of the flower-stem. 

Subdivisions op the Calyx. 

Every Calyx is either monophyllous, consisting 
of one leaf ; or polyphyllous, consisting of more than 
one leaf. 

1. Perianth. That calyx which adjoins and sur- 
rounds the other parts of the flower, as of the 
apple, rose, &c. About two thirds of all plants 
have perianths. 

2. Involucre. That calyx which comes out at some 
distance below the flower, and never encloses it. 
It is commonly at the origin of the peduncles of 
umbels, and sometimes attached to other aggre- 
gate flowers. 

Involucres are either universal, placed at the 
origin of the universal umbel, as in caraway, lo- 
vage, &c. ; or partial, placed at the origin of a 
particular umbel, as in coriander; or proper, 
placed beneath a single flower. 

3. Spalhe. That kind of calyx, which at first en- 
closes the flower, and after it expands is left at a 
distance below it, as daffodil, onion, Indian tur- 

4. Glume. That kind of calyx which is compos- 
ed of one, two, or three valves or scales, com- 
monly transparent at the margin, and often ter- 


minated by a long awn or beard. All grasses 
have glume calyxes. 

5. Ament. An assemblage of flower-bearing 
scales, arranged on a slender thread or recep- 
tacle ; each scale generally constituting the la- 
teral calyx of a flower, as in the willow, chesnut, 
pine, &c. 

C. Calyptre. The cap or hood of pistillate mosses, 
resembling in form and position an extinguish- 
er set on a candle. Conspicuous in the common 
hair-cap moss. 

7. Volva. The ring or wrapper at first enclosing 
the pileus or head of a fungus ; and which, after 
the plant has arrived to maturity, contracts and 
remains on the stem or at the root. 

Subdivisions of the Corol. 

Every corol is either monopetalous, consisting 
of one petal ; or polypelalons, consisting of more 
than one. 

Monopetalous Corols are, 

1. Bell-form. Hollowed out within the base, and 
generally diverging upwards, as Canterbury bells, 
gentian, &c. 

2. Funnel-form. With a tubular base, and the 
border opening gradually in the form of a tun- 
nel, as thorn-apple, morning-glory. 

3. Salver-form. Having a flat spreading limb or 
border, proceeding from the top of a tube, as 
lilac, trailing arbutus, &c. 

4. Wheel-form. Having a spreading border with- 
out a tube, or with an exceeding short one, as 
borage, laurel. 


5. Labiate, A labiate corol is divided into two ge- 
neral parts, somewhat resembling the lips of a 
horse or other animal. Labiate corols are either 
personate, (with the throat muffled,) as snap-dra- 
gon ; or ringent, (with the throat open,) as mint, 
motherwort, catnip, monkey-flower. 

Polypetalous Corols are, 

1. Cruciform. Consisting of four equal petals 
spreading out in the form of a cross, as radish, 
cabbage, mustard, &c. 

2. Caryophylleous. Having five single petals, each 
terminating in a long claw, enclosed in a tubular 
calyx, as pink, catchfly, cockle, &c. 

3. Liliaceous. A corol with six petals, spreading 
gradually from the base, so as altogether to ex- 
hibit a bell- form appearance, as tulip, lily, &c. 

4. Rosaceous. A corol formed of roundish spread- 
ing petals without claws, or with extremely short 
ones, as rose, apple, strawberry, &c. 

5. Papilionaceous. A flower which consists of a 
banner, two wings and a keel, as pea, clover, &c. 
If a corol agrees with none of the above descrip- 
tions it is called anomalous. 

Subdivisions op the Stamen. 

3. rfnlher. The knob of the stamen, which con- 
tains the pollen ; very conspicuous in the lily, 

2. Pollen. The dusty or mealy substance contain- 
ed in the anthers. 

3. Filament. That part of the stamen which con- 
nects the anther with the receptacle, calyx, or 

systematic terminology. 13 

Subdivisions op the Pistil. 

1. Stigma, The organ which terminates the pistil ; 
very conspicuous in the lily, and hardly distin- 
guishable in the Indian corn. 

2. Germ. That part of the pistil which in maturi- 
ty becomes the pericarp and the seed, as in the 
cherry, pompion. 

3. Style. That part of the pistil which connects 
the stigma and the germ; very conspicuous in 
the lily, wanting in the tulip. 

Subdivisions of the Pericarp. 

1. Silique. That kind of pod which has a lon- 
gitudinal partition, with the seeds attached al- 
ternately to its opposite edges, as radish, cab- 
bage, &c. 

2. Legume. A pod without a longitudinal parti- 
tion, with the seeds attached to one suture only, 
as the pea, &c. 

3. Capsule. That kind of pericarp which opens 
by valves or pores and becomes dry when ripe, 
as the poppy, which opens by pores, and the 
mullein by valves. 

4. Drupe. That kind of pericarp which consists 
of a thick fleshy or cartilaginous coat enclosing 
a nut or stone, as in the cherry, in which it is 
said to be berry-like, and in the walnut, where it 
is dry. • 

5. Pome. A pulpy pericarp without valves, which 
contains within it a capsule, as apples, quinces, 

6. Berry. A pulpy pericarp enclosing seeds with- 
out any capsule, as currant, grape, cucumber. 


7. Strobile. An anient with woody scales, as the 
fruit of the pine. 

Subdivisions op the Seed. 

1. Cotyledon. The thick fleshy lobes of seeds ; 
very manifest in beans, whose cotyledons grow 
out of the ground in the form of two large su- 
culent leaves. Many plants, as Indian corn, 
wheat, the grasses, &c. have but one cotyle- 

2. Corcle. The rudiment of the future plant, al- 
ways proceeding from the cotyledon : easily dis- 
tinguished in chesnuts, acorns, &c. 

3. Tegument. The skin or bark of seeds, it se- 
parates from peas, beans, Indian corn, &c. on

2. Common. That which connects several dis- 
tinct florets, as in the sunflower, daisy, teasel. 

3. Rachis. The filiform receptacle, connecting 
the florets in a spike, as in Jieads of wheat. 

4. Columella. The central column in a capsule to 
which the seeds are attached. 

5. Spadix. An elongated receptacle proceeding 
from a spathe, as Indian turnip. 

General divisions of Flowers. 

1. Simple. Having a single flower on a receptacle, 
as in the quince, tulip, &c. 


2. Aggregate. Having on the same receptacle, 
several flowers, whose anthers are not united, as 
teasel, button- bush, &c. 

3. Compound. Having several florets on the same

1. Whorl. In which the flowers grow around the 
stem in rings one above another, as motherwort, 

2. Raceme. Having the florets on short pedicels, 
arranged along a general peduncle, as cur-

6. Umbel. Having the flower-stems diverging 
from one place like the braces of an umbrella, 
bearing florets on their extremities, as carrot, 
dill, fennel, &c. 


7. Cyme. It agrees with the umbel in having its 
general flower-stems spring from one centre, but 
differs in having those stems irregularly subdivid- 
ed, as elder, &c. 

8. Corymb. In the corymb the peduncles take their 
rise from different heights along the main stem, 
but, the lower ones being longer, they form near- 
ly a level top, as yarrow. 

9. .Fascicle. In general external appearance it 
resembles the umbel, but the foot-stalks are irre- 
gular in their origin and subdivisions, as sweet- 

10. Head. In this the flowers are heaped together 
in a globular form without peduncles, or with 
very short ones, as clover. 

Roots and Herbage. 
The substance of Roots and Herbage consists of: 

1. Cuticle. The thin outside coat of the bark, 
which seems to be without life, and often transpa- 
rent. Very conspicuous on some kinds of birch, 
cherry, currant-bushes, &c. 

2. Cellular integument. The parenchymatous sub- 
stance between the cuticle and bark, often 
green. Easily seen in the elder, &c. after re- 
moving the cuticle. 

3. Bark. The inner strong fibrous part of the 
covering of vegetables. 

!. Camb. The mucilaginous or gelatinous sub-

All Vegetables are divided into twenty-two* 
classes. These classes are divided into orders. 
Orders are divided into genera. Genera are di- 
vided into species. Species are frequently chang- 
ed into varieties. Varieties, however, are more pro- 
perly within the province of the Gardener, than of 
the Botanist ; at least the method of procuring va- 

When a Botanist finds a plant which he never saw 
before, and wishes to know its name and uses ; he 
proceeds as follows. 

1. He takes the unknown flower in his hand, (no 
unknown plant can be ascertained without the flow- 
er,) and compares its parts with the description of 
each class, until he finds the class to which it belongs. 

2. He then goes to the orders of that class and 
finds its order in the same way. 

3. Next he goes to the genera of that order, and 
reads their descriptions, until he finds the genus to 
which it belongs. 

4. At last he looks over the species of that genus, 
until he finds the exact description of his plant, 

5. Thus he finds the Apple to be Class 12, Or- 
der 5, Genus Pyrus, Species Malus. 

* Linneus divided them into 24 classes. But farther discoveries, 
since his death have proved the classes Polyadelphia and Polygamia 
to be too uncertain and variable to be any longer retained Per- 
eoon, therefore, and other eminent botanists have rejected them. 
See these classes in the Dictionary.

floret has a perianth of its own. 

In the 22d class, the orders are distinguished by na- 
tural family characters. 1. Filices, (ferns) which bear 
fruit on the back of the leaves, or in which some part 
of the leaves seem as it were metamorphosed into a 


kind of fruit-hearing-spike. The appendix to tlnsordet 
includes the Pterioides, which bear fruit on a peculiar 
appendage. 2. JMusci, (mosses) which hear, on leafy 
items and branches, one-celled capsules, opening at the 
top, where they are covered by a peculiar lid. 3. He- 
paticae, (liverworts) which bear, on herbaceous fronds, 
four-celled capsules opening with four valves. 4. Algae, 
(seaweeds, &c.) which bear in an aquatic or gelatinous 
frond, vesiculous or filamentous fruit. 5. Lichcnes, (li- 
chens) which bear fruit, on fibrous, compact or gelati- 
nous fronds ; contained in clefts, spangles, puffs, buttons, 
tubercles, hollows, cellules, globules, shields, targets, 
orbs, or knohs. 6. Fungi, (mushroom, &c.) which are 
destitute of herbage, consisting of a spongy, pulpy, 
leathery, or woody substance, and bear fruit in a naked 
dilated membrane, or within the substance of the plant. 


Latin names are printed in Italics. But when the Latin 
and English differ only in a terminal letter or two, the 
Latin is often omitted. The orders are in Italic 
CAPITALS, and the classes in Roman CAPITALS. 


Abbreviated pe'rianth. Shorter in proportion to 
its breadth, than is generally observed in other 

Abbrevia'tions. Although any botanist may em- 
ploy such abbreviations as best suit his purpose, 
by explaining their import ; yet the following are

A'ges of plants. Some plants spring up, flower, 
ripen seed, and die in a few hours or a day, which 
are called ephemeral. Others live a tew months, 
or a summer, which are called annual. Others 
spring up in one summer and ripen and die the 
next, which are called biennial. Others live an in- 
definite period, either with the whole stem and 
branches, or only by the root, which are called 

The ages of trees may be known by counting 
the concentric rings, or grains. Our author, Ri- 
chard, supposes that trees have three ages. 1. 
The age of increase, or growth. 2. The age of 
maturity, when there is no increase. 3. The age 
of decay. But is there not sufficient proof, that 
all trees, while in a living state, continue to deposit 
new layers of wood every year ? If so, the age of 
maturity must be rejected. 

A L G 33 

Ag'grecate. Many springing from the same point 
or from the same receptacle. Sometimes this term 
is rather loosely applied to heaps or bundles. 

Aggregate flowers are those where several stand 
on the same receptacle without united anthers. 
•These flowers have rarely any inclination to yel- 
low colour like compound flowers ; but are blue, 
purple, or white. See Smith, page 308. 
Ai'grette, Egret. The flying, feathery or hairy 
crown of seeds ; as the down of thistles and dan- 
delions. It includes whatever remains on the top 
of the seed after the corol is removed. 

stiped (stipulatus) when it is supported on a 

foot-stem. .. 

simple (simplex) when it consists of a bundle 

of simple hairs, without branches. 

plumose (plumosus) when each hair has other 

little hairs arranged along its sides, like the beards 
on a feather.

On these authorities, it is introduced here from 
the French botanists.

ALGM. The fourth order of the class cryploga- 
mia ; containing those sea-weeds and aquatics ot 

34 A M E 

fresh waters, which are apparently mere pellicles 
or membranes ; or branching leaves with bubbles 
along their substance; or mere formless fibres in 
appearance. The definition of this order is : The, 
fruit is vesiculous or filamentous , in an aquatic or 
gelatinous frond. 

Linneus comprised the plants of the orders 
Hepaticae and Lichenes under this order. 

A'lienated. When the first organs, as the stamens, 
leaves, &c. give place to others different from the 
natural habit of the plant.

Alternate. Branches, leaves, flowers, &c. are 
alternate, when arranged upon opposite sides of 
the stem, or whatever supports them ; beginning

Anal'ogy. In botany, it is frequently necessary to 
reason from analogy. That is, after becoming 
acquainted with those organs which usually ac- 
company each other, if we discover one of them 
in analysing plants, we frequently assume the 
existence of others when the latter are too mi- 
nute for inspection. This principle becomes in- 
dispensable in most cryptogamous plants. 

Anal'vsis. To analyse a plant botanically, is to 
search out the number, form, position, &c. of its 
organs, as they exist in a natural state. But to 
analyse chemically, the parts must be decomposed, 
combined with tests, &c. 

Ariceps. Sec ancipital, 

Ancip'ital. Two-edged. Having two opposite 
edges or angles.

dragon.) Scrophularia (fig-wort.) Fedicularis 
(louse- wort) are examples. 

36 APE 

An'gular. By means of intervening grooves, the 
stems, calyces, capsules, &c. often have ridges 
running lengthwise, which give them this appel- 
lation. Sometimes the angles project considera- 
bly ; particularly the side-points or projections 
of leaves, which are also called angles.

by the aid of systematic arrangement, enables 
us ; 1st, to find out the name of any plant before 
unknown to us ; 2, to ascertain its general medi- 
cal and economical uses. Whether the physiolo- 
gy of vegetation is strictly a part of the science 
of Botany or of Natural Philosophy, we will leave 
to school-men to decide. 

Though Materia Medica comes not under this 
head, no one can study it with satisfaction to him- 
self without a knowledge of botany. 

Botan'ical Exercises. Learners should be exer- 
cised in the application of botanical terms, after 
having committed to memory the elementary 
names and definitions, or the grammar of botany. 
This should be done by question and answer as 

Let each pupil have a specimen of some com- 
mon simple flower. The teacher must point to 
each part of it and ask its name ; to which the pu- 
pil must answer from these definitions. After the 
application of the names of the various parts of 
fructification is understood, all the other parts of 
plants must be attended to in the same manner. 
In a few weeks, the pupils may enter upon that 

14 BOT 

practical part of the science, which leads to the 
discovery of the names of plants. Exercises in 
that part should be repeated in the following man- 
ner, with every plant, which pupils can procure. 

Common apple flower. 
Teacher. To what class does it belong ?

It will be perceived, that a suitable system de- 
scribing the plants of the country where pupils 
are taught, is essential. 

Though the lecturer's chair is a more dignified 
place than that of one in such a schoolmaster-like 
employment ; yet the pupils will derive more be- 
nefit from a season spent in this way, and in col- 
lecting and preserving plants, than from half a do- 
zen courses of formal lectures. See herbarium. 
Botan'ical Garden. A few rods of ground enclos-

ed, comprising the border of an old garden or rub- 
bish ground, will produce many species of wild 
native plants. If to this be added all the wild 
roots which show a little herbage in April, as well 
as the wild shrubs in the neighbouring woods ; a 
very amusing and instructive wild botanic garden 
in miniature may be had, containing two or three 
hundred species of plants, at a very cheap rate.

hard nor so sharp. 

3. Leaf and Flow' er-b earing. Which are gene- 
rally smaller than either of the other kinds. See 

Bulb. Bulbus. Bulbous roots. Though we call 
the turnip, the onion, &c. roots, they are strictly 
buds; or the winter residence of ihe future plants. 
Some bulbs are borne above ground, as on seve- 
ral species of onion, (allium.)

where with the same membrane ; containing seeds 
without cells, or cases. Smith. 

C A L 47 


<Jadu'co«s. Any part of a plant is caducous, which 
falls off earlier, compared with other parts of the 
same plant, than is usual for similar parts in most 
plants. As the calyx of the poppy falls off before 
the corol is hardly expanded. 

Coeru'leo-purpur'eus. Blue- purple, violet colour.

Calyp'tra. Calyptre, or veil. The cap or hood of 
pistillate mosses ; resembling in form and position 
an extinguisher set on a candle. It is ranked 
among calyxes, and so used in descriptions. But 
in reality it is the corol closed; which after being 
detached at the base like other corols, its form still 
keeps it on the capsule a while. See villose, also 
Perichxzlium, which is the true calyx of mosses. 

Calyptra'tus. Having a calyptre.

Ca'lyx. {Kaluxy Gr.) That, floral organ, which 
proceeds from the germ, receptacle, or pedun- 
cle, below all the other organs. It is generally 
green ; or, in botanical language, not coloured. 
When the calyx or corol is wanting, it is often 
difficult to determine which is present. Our au- 
thor, Richard, says : when but one is present, it 
ought always to be called the calyx. But as no 
one can change the language of botanists, which 
is already adopted in descriptions of plants, we 
must endeavour to understand it as it is. 

If the stamens alternate with the leafets or divi- 
sions, Linneus calls it a corol; and if the stamens 
stand opposite to the leafets or divisions, he calls 
it a calyx, without regarding the colour or tex- 
ture. Where the stamens are numerous, this rule 
cannot apply ; neither has Linneus made it ne- 
cessary in his descriptions. 

Willdenow's rule. The Calyx is hardly as long 
as the stamen ; the corol quite as long or longer ; 
the calyx green and firm ; the corol coloured and 
tender. This rule is to apply where but one of the 
organs is present ; and he allows a lew excep- 
tions to this.

ther ; as in the holly-hock, (althea.) 

common. When one calyx includes many flo* 

rets, as the thistle. 

proper. When florets, included in a general 

calyx, have calyxes of their own. 

There are seven kinds of calyx : 1. Perianth. 
2. Involucre. 3. Spathe. 4. Glume. 5. Ament. 
6. Calyptre. '. Volva. See each. 

Camb, ♦ im'bium Du Hamel's name for the mu- 
cilagi or 8 latinous substance between the 

wood ami bark. 

CAP 4a 

At the time of the year when the camb is most 
abundant, many farmers in North America have 
peeled off all the bark from the body of bark-bound 
apple-trees ; it is soon replaced, especially if 
carefully wound up in swingling-tow, &c. But 
the slightest scratch upon the camb will cause a 
large opening in the new bark, and leave a large 
spot of dry dead wood. The same is always ob- 
served in the operation of inoculating trees. 

Every one, who is accustomed to observe Ame- 
rican forest trees, has frequently seen trees which 
are injured by the frequent fires in the woods, 
whose whole bole is totally dead, leaving a mere 
thin sheet alive next to the bark, on the side op- 
posite the course of the fire ; and still these trees 
continue to grow, flourish and bear fruit as usual. 
Then if all outside of the camb may be taken off, 
and all inside destroyed, and the tree still survive, 
it is evident that it is by means of the camb that 
the tree is supported. More especially as the least 
removal of camb is always succeeded by dead 
wood ; all other parts remaining undisturbed. 

Campan'ulate, Campanula' tus. See bell-form. 

Campes'tris. Growing in uncultivated fields. 

Canalicula'tus. See channelled. 

Can'cellate, Cancella'tus. See latticed.

by sprinkling pollen "upon them. This is impor- 
tant in raising figs. 

Cap'sule, (cap'sula, a little chest.) That kind of 
pericarp, which opens by valves and becomes dry 
when ripe ; not including siliques nor legumes. 
When it is one-valved, it is called a follicle, 
follicidus, which see. It consists of valves, par- 
titions, columella, and cells, which see. One kind 
of capsule never opens and is called samara. 

Cari'na. See keel. 

Car'inate. See keeled. 

Carina'tus. See keeled. 

Car'neous, Car'neus. Flesh-coloured. Nuttall uses 
it for fleshy. 

Carno'se, Carno'sus. Fleshy. 

Car'pogena'tion. {Karpos, fruit ; gennao, to bring 
forth.) A substitute for the word fructification. 
A multiplication of terms is very injurious to the 
science. But in teaching botany to young per- 
sons, a word so often to be repeated and so very 
difficult to pronounce, is extremely troublesome. 
This term is both easy and perfectly applicable. 
In a synopsis presented to Professor Mitchill of 
New- York, this substitute was proposed and re- 
ceived his approbation. 

Cartilaginous. Hard and somewhat flexible. It 
applies to a leaf, when it is bound around with a 
strong margin, different from the disk of the leaf. 

Caryophyl'leous. Pink-like, as to the corol ; hav- 
ing five petals with long claws, all regular and set 
in a tubular calyx.

CER 51 

Caules'cent, caules'cens. Having a caulis, or stem, 

besides the peduncle or scape. 
Cau'line, cau'linus. Growing on the main stem. 
Cau'lis. The main herbage-bearing stem of all 
plants, except of the grassy kind ; as trees, weeds, 
&c. We have no English name for this stem ; 
neither can any English termination assimilate this 
term with ouridiom. It has been usual in such 
cases to look into some modern language for a 
suitable term. How would the French word Tigt 
be received ? (Pronounced tidge in English.) 

Cell. The hollow part, or cavity of a pericarp or 
anther. It is more generally applied to the cavi- 
ties of pericarps, where seeds are lodged. Ac- 
cording to the numbers of these the pericarps are 
called one-celled, two-celled, &c. 

Cel'lular integument. The parenchymatous sub- 
stance between the cuticle and bark. This sub- 
stance is generally green. It constitutes the most 
considerable part of leaves ; in which the juices 
are operated upon by air and light, and the pe- 
culiar secretions of vegetables principally elabo- 

Cel'lules, cis'tula. That kind of receptacle of 
lichens, which is globose, terminal, and formed of 
the substance of the frond. It is filled with un- 
coated seeds, intermixed with fibres ; at length it 
bursts irregularly. Smith. 

Celltdosus. Cellular. Having cavities within, which 
are small and irregular ; and in which sometimes 
granules are nested. 

Centralis. In the eentre. 

Cep halo did. See knobs.

bends down. See nutans, and the difference in 
the two terms. 

Ces'pitose. See Casspitose. 

Chaff. Thin membranous covering of the seeds ot 
grass, grain, &c. See glume. It is also applied 
to whatever resembles chaff; as the substance left 
on the receptacles of some compound flowers, af- 
ter the seeds are removed ; to the crown of some 
seeds, &c. 

Chaf'fy. Bearing chaff. 

Channelled. Hollowed out longitudinally with a 
rounded groove of considerable depth. 

Char'acter. That description of a plant, which dis- 
tinguishes it from all others. In making out the 
character, Situation, Proportion, Connection, 
Number and Figure, are considered. The two 
last are not so constant as the other three. 

Generic characters are limited to the flower and 

Specific characters are restricted no farther, 
than to avoid running into the characters of the 

G'ho'rion. A clear limpid liquor contained in a 
seed in the time of flowering. This liquor, after 
the pollen is received, becomes a perfect embryo 
of a new plant, and takes the consistence usual in 
perfect seeds. But without the reception of the 
pollen, neither any thing like the embryo or per- 
fect seed, is ever formed. Malpighi. 

Ghrysoc'omus. Golden locks; or a yellow bundle 
of threads. 

Cic'atrice, Cica'trix. The mark or natural scar 
from whence the leaf has fallen. 

Cil'iate, cilia'tus. Edged with parallel hairs or 
bristles, resembling eye-lashes.

tip, which continually occupies the centre; as 

Circina'tus. Circinal. Also compassed about. 

Ctrcumcisus. Cut round. Opening transversely, 
not lengthwise ; as the capsules of purslain. 

Circnmscrip'tio. The circumference of a leaf. 

Cirrif'erus. Bearing tendrils. 

Cirro'se, cirro'sus. Terminating in a tendril. 

Cir'rus. (Curled bushy hair.) See tendril. This 
term is also applied to that kind of clouds which 
resembles flax, as it is pulled from the distaff. 
This kind of clouds ascends 4 or 5 miles high ; 
much higher than any other kind. 

Cis'tula. See Cellules. 

Clam'mv. See viscid. 

Clas'per. See tendril. 

Clas'ping. The base of the leaf being more or less 
heart-form and sessile, so that the two hind lobes 
partly surround the stem. 

Class, clas'sis. The highest division of plants in a 
system. Each class is defined to be the agree- 
ment of several genera in the parts of fructifica- 
tion, according to the principles of nature, distin- 
guished by art. Linneus divided all plants by their 
stamens and pistils, into 24 classes ; but Persoon 
and other approved systematic writers have distri- 
buted the plants of the 18th and 23d classes 
among the others, and rejected these two ; leav- 
ing but 22 classes. These are rejected on ac- 
count of the liability of their characters to per- 
petual variations. See each ciass in its proper 
place, also system. 
Cla'vate, clava'tus. Club-form. Growing larger 
towards the end. 

H C L O 

Clavic'ula. See tendril.

it is fixed on the calyx or receptacle. It can ex- 
ist only in Polypetalous corols. 

Cleft. Split down, not exceeding half way to the 
base ; with nearly strait edges on both sides of the 
fissure. The parts into which it is split are num- 
bered in descriptions 5 as once split making two 
divisions, is called 2-cleft ; two splits, 3-cleft, &c. 

Clefts, lird'la. That kind of receptacle of li- 
chens, which is open, elongated, sessile, black, 
very narrow or linear, with a somewhat spongy 
disk ; the border is parallel on each side and pro- 
per. Sometimes it has an accessory border from 
the crust besides. The clefts are either simple 
and solitary; or aggregate, confluent and branch- 
ed. Smith. 

Climbing. Ascending by means of tendrils, as 
grapes : by leaf-stalks, as virgin's bower ; by 
cauline radicles, or rootlets, as the creeping Ame- 
rican ivy, (rhus radicans.) It differs from twining, 
which see. 

Clouds. (Though this article does not relate to the 
subject of this dictionary, it was thought proper 
to introduce it here; because the Natural History 
of clouds is not of sufficient extent to form an in- 
dependent work, and it is not to be found in any 
book of a portable size. For an extensive view 
of this subject, see Rees' Cyclopaedia, article 

Clouds may be divided into the Regular and 

CLO 55 

Regular Clouds. 

1. Strato'se clouds. They are those stratified 
horizontal ranges of vapour, which often appear 
in the morning, near and adjoining the earth ; 
usually called fog. When the sun shines upon 
them, they ascend gradually in a highly rarified 
state ; and at length re-unite in another form, and 
take the name of 

2. Cumulo'se clouds. They are those bright 
shining clouds, which have their bases straitish 
with their upper sides in roundish brilliant heaps. 
They mostly float awhile near the horizon in de- 
tached masses, and then gradually break up and 
ascend still higher in fine flakes or sprays, and 

3. Cirro'se clouds. They are those fibrous 
clouds which resemble flax when it is gradually 
pulled from the distaff. They are the highest of 
all clouds ; often forming at the height of five or 
six miles. After a few hours, they generally set- 
tle down gradually and become 

4. Cir'ro- cumulo'se clouds. They are those 
which are formed by the knotting or curdling of 
cirrose clouds. When first forming, they exhibit 
rows of small heaps, often in long regular curved 
lines very near each other. Sometimes they be- 
come confluent, and at length cover the whole 
sky. This last variety furnishes the materials 
for long steady rains. But they generally break 
up in fair weather in the afternoon, and out of 
their fragments are made 

5. Cir'ro-strato'se clouds. They are those stra- 
tified patches, seen near the horizon, mostly at 
evening; generally disappearing entirely after

Remark. This is the usual process during the 
pleasant part of spring, summer and autumn, In 
the year 18] 5. I kept an exact diary of clouds at 
Greenwich, in New York, more than five months. 
I found this to be their regular course more than 
half of that period. 

Anomalous Clouds. 

6. Nimbo'se Clouds. They are those dense 
clouds, which ascend from the horizon, at first 
with heads like the cumulose, which soon shcot 
into cirrose branches extending towards the ze- 
nith. They are usually called thunder-clouds, 
and almost always bring showers. 

7. Vello'se clouds. They are those fleecy 
clouds, which fly swiftly about the sky, of an 
open texture, without any defined sides or bases. 
One variety of these clouds is called scud. 

8. Cu'mulo-slrato'se clouds. They are the most 
rare, as well as the most remarkable of clouds. 
But one appeared in the year 1815, and I have 
observed but two since, (three years.) A cumu- 
Jous-like cloud seems to rise up from the horizon 
in a compressed channel, and to become united 
with a cirro-stratose cloud. Soon after this union, 
the cloud spreads out to great extent, and finally 
covers a great proportion of the hemisphere ; 
while its base or stem remains as at the com- 
mencement. Its form and sudden growth has 
given it the appellation of Mushroom-cloud. I 
have never seen this cloud except at six or seven 
o'clock in the afternoon. 

Clo'ven. See cleft. 
Club'-form. See clavate. 
Clus'tered. See racemed, 

COL 57 

-Cly'peate, Clypea'tus. Form of a buckler. See 

Coad'unate. With united bases.

time. Applied to willows and to some other 
plants, it implies that the flowers and leaves ap- 
pear at the same time. 

Co'alit, Coali'tus. Thickened, increased, as the 
anthers of potatoe flowers. 

Coarc'tate. Compact. Pressed or squeezed close 

Coat'ed. Consisting of concentric coats, layers 
or skins, as the bulbous root of onions.

pentacoccous, 5-seeded, &c. 

Coch'leate, cochlea'tus. Coiled spirally, like a 

Cohe'rens. Cohering, attached. 

Coil'ed. Twisted like a rope; or rather resembling 
the form of one thread of a rope, after the other 
threads arc removed. 

Colli'nus. Growing on hills. _ 

Col'oured. Of any hue except green; but in the 
language of botanists green parts are not colour- 
ed. See temperature, also glaucous. 

Colora'lus. Coloured. 

Columel'la. That which connects the seeds to the 
inside of a pericarp. It is generally applied to a 
central pillar in a capsule ; which takes its rise 
from the receptacle, and has seeds attached to it 
on all sides. In mosses it is called sporangidium 
by Willdenow ; and he sometimes applies this 
term as a substitute for columella; and says it is 
found only in 2-vaIved capsules. 

ok COM 

Colum'nar. Sec terete. 

Colurnnif'era. Stamens and pistils disposed in the 

form of a column. 
Com'a. (Kom'e, a head of hair.) A tuft of bracts 

on the top of a spike of flowers. 
Commis'sure. The place where one thing or part 
is joined to another. Nuttall applies it to sides 
or edges of two seeds, growing on umbelliferous 
plants, where they are joined together ; as those 
of the carrot and fennel. 
Com'mon. Any partis common, which serves to in- 
clude or sustain several parts, similar among 

perianth. Including several florets; as in the 

involucre. Surrounding the base of the pedun- 
cles, in an umbel, which are subdivided above.

Commu'nis. See common. 
Como'se. Having a coma. 
Compac't. See coarctus. 

Comple'te, comple'tus. Having both calyx and co- 
rol. When the corol is wanting, the flower is in- 
complete. When the calyx is wanting, the flower 
is naked, if it has a corol. 
Complicate, complica'tus. Folded together. 
Compos'itus. Compound. 

Com'pound. One whole, formed of many similar 

flowers. Those comprised in the class synge- 

nesia, with several florets on one receptacle, each 
with united anthers. 

Compound flowers are divided into five kinds 
by the relations and kinds of florets ; upon which 
divisions are founded the five orders of the syn«e. 
nesia class, 

COM 59 

1. The florets ;iro all perfect, each having 5 
stamens and one pistil. The anthers are all unit- 
ed into one set, forming a tube around the pistil. 
See a3(jualis. 

2. The Hovels of the disk are all perfect; but 
those of the ray, or the edging-florets, are pistil- 
late. See superilua. 

3. The florets of the disk all perfect ; but the 
florets of the ray neutral, having neither stamens 
nor pistils ; except in some cases they have abor- 
tive pistils. See frustranea. 

4. The florets of the disk staminate ; but those 
of the ray pistillate. See necessaria. 

5. The florets all perfect as those of the 1st 
kind ; but differ from them in each floret's having a 
little perianth of its own, which is wanting in all 
the four preceding kinds. See segregata. This 
last kind is not so common as the others. 

leaf. When several leafets grow on one petiole. 

raceme. When several racemes grow along 

the side of a peduncle. 

spike. When several spikelets grow along 

the side of a fruit-stalk, or general spike. 

umbel. Having the peduncles subdivided into 

peduncles of lesser umbels, &c. 

petiole. A divided leafstalk. 

peduncle. A divided flower-stalk. 

Com'pound terms. When any part of a plant is to 
be described, which does not agree with the defi- 
nition of any term in use ; two or more terms 
must be compounded, so as to convey to the mind 
correct information. For example the chesnut 
leaf has notches on the margin pointing towards 
the apex, which answers to the description of ser- 
rate leaves ; excepting that the notches are hol- 
lowed out. But these hollowed notches are not 


deep enough for sinuses ; therefore the two terms 
are compounded, making sinuate-serrate. Com- 
pound terms are always united by a hyphen. 

Compres'sed, compres'sus. Flattened, as if squeez- 
ed or pressed. 

Con'cave, con'cavus. Hollowed a little on one side. 
It is sometimes applied to deeper hollows ; though

leaf, while in the bud, has its two sides shut to- 
gether, like two leaves in a book. 

Cone, co'nus. See strobile. 

Confer't, confer'tus. Thick-set ; leaves, flowers, 
&c. standing so closely together, as to seem to 
crowd each other. 

Con'eluent. Running together. It is applied more 
particularly to the receptacle of some lichens, 
which run together in disorder and become indis-

CRYPTOGA'MIA. (Kruptos, concealed; gamos, 
marriage.) The name of the last class in the Lin- 
nean Artificial system. It includes those plants, 
whose stamens and pistils are too minute or ob-

side ; but the side ones are nearer to the base than 
to the apex. When the side angles are about as 
near to the apex as to the base, it is called a 
rhomboid leaf. Both kinds are called diamond- 
form in English. Willdenow considers a deltoid 
leaf as a thick 3-sided leaf, a transverse section of 
which he supposes intended, as giving the deltoid 
form. See page 155.

Descrip'tions of plants. In writing a complete de- 
scription of a plant, begin with the fructification, 
and describe: 1. Calyx. 2. Corol. 3. Stamens. 
4. Pistil. 5. Pericarp. 6. Seed. 7. Recepta- 
cle. Then go through with the root and herbage, 
thus: 1. Root. 2. Stem and branches. 3. Buds, 
including the foliation. 4. Leaves. 5. The ap- 
pendages •, that is, Stipules, Bracts, Thorns, Pric- 
kles, Stings, Glands, Tendrils. To this add the 

Then add the general appearance and size of 
the plant, and what well known plant it most re- 
sembles. Give an account of the soil and situa- 
tion where it grew ; whether high or low, wet or 
dry; the precise time of flowering, colour of all 
parts, whether annual, biennial or perennial. 
Then close with the name of the town, country, &c. 
and what quantity of the same kind of plant is to 
be found there ; and what name the common peo- 
ple call it by, if any. Accompany this descrip- 
tion with several specimens ; so selected as to ex- 
hibit the plant in all its parts. 

There can be no better exercise for students, 
than to write several such descriptions every day.

DIADEL'PHIA. (Dis, twice ; adelphos, brother.) 
Two brotherhoods. The name of the seventeenth 
class. It comprises all plants, whose flowers are 
perfect, with the stamens united by their filaments 
in two sets. This was the character given the 
class by Linneus. But Lvpines and others of this 
class have the stamens united in one set ; which 
is the character of the Monadelphia class. The 
form of the corol has therefore been taken Into 
the description by some writers, thus : 

Stamens united by their filaments in one, or two 
s-ets, cor ols papilionaceous. 

Diadel'phous. Belonging to, or varying into, the 
class diadelphia. 

Diagno'sis. A short description containing only 
what is essential. Linneus made it his rule, 
never to let a specific description exceed twelve 
Latin words. Willdenow says more must be ad- 
ded if necessary. It should extend no farther 
than to express the difference between that, and 
the other species. 

Di'amond-form. See Deltoid. 

DIAN DRIA. (Dis, twice ; aner, male.) Two 
stamened. The name of the second class. It 
comprises all plants, whose flowers die perfect. 
with two stamens in each not growing- en the pi^ti!.

one flower and pistils in another, whether on the 
same or on different plants. This is the name of 
a class in Pursh's Flora, comprising most of the 
plants of the classes Moncecia and Dioecia. 

This class is subdivided into three orders. 1. 
Segregate. This includes plants, whose flowers 
are monoecious or dioecious ; but are not in 
aments or strobiles. 2. Amentaceie. This in- 
cludes plants, whose flowers are in aments which 
are not strobiles. 3. Coniferce. This includes 
plants, whose flowers are in strobiles. 

Dicoc'cous. Two-grained. Consisting of two co- 
hering grains, or cells with one seed in each.

DIDYNAM'IA. (Dis, twice ; dunamis, power.) 
Two overtopping or overpowering others. The 
name of the fourteenth class. It comprises all 
plants, whose flowers are perfect, with 4 stamens, 
two of which are regularly longer than, or over- 
topping, the other two. Plants of this class have 
labiate corols. But on account of adhering rigid- 
ly to the character of the class, some ringents are 
placed in the 2d class. The student should be 
directed to look in the second class, under the 
sections of irregular corols, when he has a rin- 
gent flower, whose generic character he does not 
readily find in the 14th class. 

Didyn\mous. Belonging to, or varying into the 
ctass didynamia.

styled. The name of the second order in each 
of the first thirteen classes. It comprises all 
plants in each class respectively, whose flowers 
have two styles in each : or, if the styles are 
wanting, two sessile stigmas : as the blite, (bli- 
tum,) in the class monandria ; the sweet-scented 
grass (anthoxanthum) in the class diandria ; wheat

74 DRU 

Twelve stamened. The name of the eleventh 
class. It comprises all plants, whose flowers arc 
perfect, with from 12 to 19 stamens which are not 
united by their filaments in one or two sets. En- 
decandria would seem to be the proper name for 
the 1 1th class. But there has not only never been 
a plant found, whose flowers uniformly contained 
1 1 stamens ; but it is so contrary to all analogy of 
parts, it is presumed there is no such plant.

with 9 stamens in each. The number of stamens 
are very variable in most plants in this class ; 
particularly in the genus laurus, including the 
common sassafras- and spice-bush. 

It may also be the name of the ninth order in 
'hose classes where the characters of the first 13 
classes are taken for orders ; should any discove-

and unbending as strictus. When applied to any 
thing laterally attached to the stem, as leaves, &c. 
it implies that it makes a very acute angle with it. 
Erectius' cuius. Erectish. 
Er'got. See spurred rye. 
Erina'ceus. Hedge-hog- like. See uhinatus.

Ev'ergreens. Such plants as retain their leaves 
throughout the year ; as white pine, laurel, &c. 

Evergreen. Verdant throughout the year. 

Exan'nulate. Ferns whose capsules are without 
rings. This comprises one section of ferns. 
Those which have an apparent vestige of, but 
not in reality, a ring, form another section. 
Those with a ring, another. See annulatus. 

Exara'tus. See sulcate. 

Exaspera'tus. Sec roughened.

ly in a wild state in that particular country, or 
section of a country. 

Expan'ded, expan'sus. Spread. 

Explana'tus. Unfolded. 

Exsert', exser'lns. Standing out. Stamens are ex- 
sert when protruded out of the corols. Pedun- 
cles of spikes in culmiferous plants are exsert, 
when protruded out of the sheaths; as carex fol- 
liculata and pubcscens. 

Kxstip'ulate. Without stipules. 

Exsic'cup* Juiceless. 

Ex'limus. At the very top, or extreme end. 

ExTRAfoLiA'cEOUs. Outside of the leaf. A stipule 
is extrafoliaceous when it comes out a little lower 
than the leaf does. 

Exlror'sum. Outwardly. 

Eye. See hilum. 

FAS 79 

I P. 

Fac'ies. The general external appearance of a plant. 
Factit'ious character. An essential character, where 
the number of parts or some other circumstance, 
not of essential importance, are taken into it— Will- 
denow. Artificial marks distinguishing one genus 
from another — Martyn. What is not natural — 
Richard. It admits of fewer or more characte- 
ristic marks, than are absolutely necessary— Milne. 
It serves to discriminate genera that happen to 
come together in the same artificial order or sec- 
tion. It can never stand alone, but may some- 
times commodiously enough be added to more es- 
sential distinctions. — Smith. 
Fal'cate. See acinaciform. 
Fam'ilies. See gentcs. 
Fan form. Spread out, or tapering towards the 

base like a fan. 
Farc'tus. Stuffed, full. It is opposed to fistulous, 

Fari'na. See pollen. 
Farino'sus. Mealy, powdery. 
Fascia'las. Having parallel bands, or coloured 

Fas'cicle, fascic'ulus. A bundle. Flowers level- 
topped, umbel-like in the general external appear- 
ance, with footstalks irregular in their origin and 
subdivision. The fascicle differs but little from 
the corymb, excepting Jn having shorter foot- 
stalks, which do not extend so far down the main 
stem. Sweet-william (dianthus) is a good exam- 

A bundle of tuberous roots is called a fascicle ; 
as the asparagus roots. Also a bundle of leaves ; 
as of the white pine. 

80 FIG 

Fascic'ulate. An unnatural bundle of branchlets. 
F astiq' i ate, fas tigia'tus. Level-topped. Applied 
to aggregate flowers, which are elevated to an 
equal height or nearly so ; forminga level, convex, 
or concave top, differing but little from a plane. 
It is also applied to leaves ; as the hog-weed (am- 
brosia artemisifolia.) 
Favo'sus. See alveolate. 

Faux. Jaws. The throat or opening into a corol. 

That precise spot, where the tubular part of a rin- 

gent corol begins to separate or expand into lips 

or mouth, is the faux. 

Feat'her. See Aigrette. The plumose crown of 

F e'm ale, femin'eus. See pistillate. 
Fence. Involucre of Withering. 
Fen'ced. Walled around, as the stamens are by the 

scales in brookweed (samolus.) 
Fe're. Almost. 
Ferns. See Alices. 

Ferru'ginous, ferrugin'eus. The colour of iron- 
rust. See glaucous. 
Fer'tile. See pistillate. 

Fertilization. The application of the pollen, 
which is formed in the cells of anthers, to the stig- 
ma ; which is essential to the production of per- 
fect seed. See chorion. Richard is too lengthy 
upon this subject for the plan of this Dictionary ; 
which is intended for definitions and illustrations, 
but not for physiological discussions. 
Fi'bre, fi'bra. Any thread-form part. The small 
flexible thread-form roots of grasses and many 
other plants, are called fibres. 
Fi'brous. Composed of fibres. 
Fid'dle-form. See panduriformis. 
Figu'ra. See icones. 

FLA 81 

Figura'tum. This term is applied to the mouth of 
the capsule of a moss, when it is set round with 
membranaceous teeth. 

Fil'ament, fi lame n' him That part of the stamen 
which is between a. id connects together the an- 
ther and the re-.ep ado, calyx or pistil. When 
the filament is wanting, the anther is sessile. In 
monopetalous corols, the filaments are generally- 
inserted into, or are attached to, their bases. 
FIL'ICES, ferns. The first order of the class cryp- 
togamia. It includes all that natural family of 
plants, whose fruit grows on the backs of leaves, 
on a peculiar appendage, or on a leaf (frond) 
wholly metamorphosed into a kind of fruit-bearing 
spike. See cryptogamia, annulatus, and exannu- 
latus. Brake, polypod, and maidenhair belong 
to this order. 

Fil'iform. Thread-like. Of nearly equal thick- 
ness throughout, round and cylindric. It is ap- 
plied to spikes which are very long in proportion 
to their diameters. But it is generally confined 
to smaller parts. 

Fimbria'lus. Fringed. Differs from ciliate in being 
less regular and of coarser parts. 

Fimeta'rius. Growing naturally on manure-heaps. 

Fin'gered. See digitate. 

Fis'sure. A cleft or slitted aperture. 

Fis'sus. See cleft. 

Fis'tulous. Hollow like a pipe, flute or reed.

82 FLO 

Fla'vus. Yellow. 

Flesh'y. Thick and filled with pulp within. 

Flex'ible, Jlex'ilis. Easily bent. 

Flexuo'se. Bending and frequently changing direc- 
tion. A stem is flcxuose, or zigzag, which uni- 
formly bends at regular intervals ; as from joint 
to joint, branch to branch, leaf to leaf, &c. 

Flex'us. Bent. This relates to but one bending. 
See geniculate. 

Flo'ating. See natant. 

Flocco'se. Woolly, or resembling the flocks shear- 
ed from cloth. 

Floral. Relating to a flower. 

bud. Containing an unopened flower. 

leaf. See bract. 

Florescen'tia. See efflorescentia. 

Flo'ret. Little flower. Whether the flower is 
large or small, it is a floret, if it is one of a num- 
ber all of which constitute an aggregate or com- 
pound. As the little flowers which make up the 
head of a thistle, a head of wheat, the umbel of a 
carrot, Szc. 

Floribun'dus. Abounding in flowers. 

Florif'erous. Bearing flowers. A leaf is florife- 
rous when a flower grows out of its disk or mar- 

Flo'rist. One whose employment is that of creat- 
ing monsters ; that is. double and various colour- 
ed corols ; as carnations, double roses, Szc. These 
meet a more ready sale than the most interesting 
plants in their native state, among persons of- a 
coarse unscientific taste. Such persons, to be con- 
sistent, should prefer the high coloured daubings 
of a sign painter, to the delicate touches of a Sa- 
vage, a Trumbull, or a Vanderlin. 

Flos. See flower. 

F O L 83 

Flos'cular, flosculo'sits. See tubulous. 

Flos'culus. Tubular floret. Nuttall applies it to 
the florets of grasses ; but ought not to be follow- 

Flow'er. The stamens and pistils with their cover- 
ing. These two organs, or rather their anthers 
and stigmas, are essential to all plants. But the 
calyx, corol, and even nectaries when present, are 
parts of the flower. The flower is perfect with a 
single stamen and pistil. But if either of these be 
wanting, it is imperfect, however splendid and gay 
the corol, &x. as it can never bring forth perfect 
seed nor in any manner produce its kind. Raising 
plants from bulbs, roots, &c. is now known to be 
only an extension of the same individual, which 
will cease to grow, when it arrives to its stated 
limits. For this reason grafts from a kind of tree 
long known and often transferred from tree to tree, 
sooner die of old age, than those taken from a 
kind later from the seed. It is for this reason 
also, that any kind of potatoe, however excellent, 

- ceases to produce good crops, after being for 20 
or 30 years extended by planting the root. It 
must be renewed from the seed from time to time, 
or become extinct. Smith says," all other modes 
of propagation (excepting by the seed) are but the 
extension of an individual, and sooner or later 
terminate in its total extinction." See page 240. 

Flow'ering se'ason. See efflorescentia. 

Flow'er stalk. See pedunde. 

Fluvia'tilis. Growing naturally in rivers and brooks. 

Fiz'tidus. Smelling disagreeably. 

Fold. Annexed to numerals denoting so often com- 
bined ; as 5-fold leaves, growing in fives, &c,

Fora'men. A hole. 

Foraminulo'sus. Pierced with many small holes. 

Fork'ed. See dichotomous. 

Fornica'tus. Arched. See vaulted. 

Fov'ea. A nectariferous cavity for the reception of 

Fovil'la. The fine substance contained in the parti- 
cles of pollen. When the ripe pollen comes it: 
contaci with the moist stigma, it explodes and dis- 
charges the fovilla. 

Frag'ilis. Breaking easily and not bending. 

Free. See libera. 

Freq'uens. Very common, or frequent. 

FH'gidus. Growing naturally in cold countries. 

Fain'ged. Sec firnbriatus. 

Frond. An herbaceous, a leathery, a crustaceous, 
or gelatinous leaf, or somewhat of a leaf-like sub- 

F R U 85 

stance, from which or within which the fruit is 
produced. It is applied exclusively to the class 
eryptogamia — Smith. But formerly it was also 
applied to palms. 

Frondescen'tia. See leafing. 

Frondo'se. Frondo'sus. Leafy, or leaf-like. It is 
applied to mosses to distinguish them from liver- 
worts by Willdenow ; who retains them in the 
same order. 

Frons. See frond. 

Frutescen'iia. Applied to palms and such others as 
have a simple stem, and leaves only at top. 
Willdenow, page 268. 

It is applied by Martyn to the time when vege- 
tables scatter their ripe seeds. 

Fructif'erous. Bearing, or becoming, fruit. 

Fructifica'tion, fructified' tio. " The temporary 
part of vegetables, which is destined for the re- 
production of the species, terminating the old in- 
dividual and beginning the new." — Linneus. It 
consists of seven parts ; 1. Calyx. 2. Corol. 3. 
Stamen. 4. Pistil. 5. Pericarp. 6. Seed. 7. 
Receptacle. See each in its proper place. 

Fruit, fruc'tus. The seed with its enclosing peri- 
carp. If the seed grows naked, the seed alone is 
the fruit ; as of the sage. 

Fruit'-dots. Assemblages of capsules on the backs 
of ferns. Also small assemblages of powdery bo- 
dies on the fronds of lichens, called soredia. 

Fruit'-stalk. See peduncle. 

FRUSTRA'NEA. (Frustra, in vain,) polygamia. 
The 2d order of the class syngenesia. The florets 
of the disk are perfect, of the ray neutral. Ex- 
amples. Helianthus (sunflower.) Centaurea 
(bluebottle. 1 ) 



Frutes'cent, frutes'cens. Woody ; or from herba- 
ceous becoming woody. 

Frut'ex. A shrub, which see. 

Frutico'sxts. See shrubby. 

Fug'ax. Fugacious. Soon disappearing. Flying 
off. See ring. 

Fulcra'lus. Having appendages. 

Fulcrum. These are seven — 1. Stipule. 2. Bract. 
3. Thorn. 4. Prickle. 5. Sting. 6. Gland. 7. 
Tendril. See each in its proper place. 

Full-flowered. When the petals of the corol are 
so multiplied as to exclude the stamens ; which is 
effected by the stamens becoming petals ; as the 
peony, rose, &c. This rarely takes place in mo- 
nopetalous corols. Double flowers are totaly un- 
fit subjects for botanical exercises. See florist. 

Ful'vous, Ful'vus. Yellowish, rust-colour. 

FUNGI) funguses. The sixth order of the class 
cryptogamia. It comprises that natural family of 
plants which is totally destitute of all herbage or 
herbaceous substance, but is of a spongy, pulpy, 
leathery or woody texture. See Angiocarpus and 
gymnocarpus, also cryptogamia. 

They are now known to be organized bodies, 
propagating their kind by seeds, like other vege- 
tables. However unsightly a common toadstool, 
the mould on old scraps of leather in damp 
places, or the blight in grain, may appear to the 
careless observer; they are all beautifully or- 
ganized, and highly interesting to the student in 
Natural History. But " their sequestered and 
obscure habitation, their short duration, their mu- 
tability of form and substance, render them indeed 
more difficult of investigation than common plants." 
Smith, page 500. 

Fungo'se. Fleshy and spongy. 

GAS 87 

Fun'gus. This term is sometimes put for pileus. 

Fu'nicule, Funiculus umbilica 'lis . The thread 
by which a seed is fastened at the hilum. 

Fun'nel-form. A corol with a tubular base, and a 
border opening gradually into the form of a re- 
versed cone. 

Furca'tus. See dichotomous. 

Fur'rowed. See sukate. 

Fus'cus. Sooty-yellow, dark-yellow. 

Fusiform, fusifor'mis. Spindle-form. A root thick 
at the top and tapering downwards to the point 
is fusiform ; as the beet and carrot. 


Galea. See labiate. 

Ga'leate, Galea'tus. Resembling a helmet. 

Galls, gal'lce. Excrescnces produced by the stings 
of insects. The balls found on oaks which are 
used in dyeing, the common large green oak-balls, 
the singular green lumps found on the wild ho- 
ney-suckle, «fec. are examples. The irritation 
upon the delicate sap-vessels, produced by the 
sting and egg of the insect, causes a greater flow 
of sap in that direction. This pressure of sap 
distends and distorts the capillary tubes and mem- 
branes, until those excrescnces are formed around 
the egg. In due time the egg becomes a larva, 
or maggot, which after feeding a while upon the 
gall, changes into the pupa, or chrysalis, and at 
last escapes a perfect insect, or fly. Each fly pro- 
duces a gall of a peculiar form. Willdenow. 
Gape. The opening between two lips of a labiate, 

or irregular, corol. 
Gap'ing. See hians. 
Gas'hed. See incisus. 

88 GEN 

Gem'inus. See double. It is also used for paired, 
in pairs or twins. 

Gem' ma. See bud. 

Gemma' t to. Budding. The gemmation of plants 
comprehends the dcvelopement of a new plant 
from the bud, as well as the foliation ; according 
to Richard. See foliation. Buds arc of four kinds. 
I . Bud, properly so called, which see. 2. Turion, 
'he radical bud,* or lender shoot which rises from 
the root in the spring, before it expands its leaves ; 
as the early asparagus shoots. 3. Bulb, which 
see. 4. Propago, a longish round body proceed- 
ing from the mother plant in mosses, which itself 
becomes a new plant. This is placed among the 
buds by Richard : but Linneus calls it the seed ; 
and Gartner applies it to the seed of lichens also. 

Gemmip'arous. Producing buds in the axils of 

Gen'eral. See partial. 

Gen'eral fence. Universal involucre. 

Geker'ic char'acter. The definition of a genus. 
It is confined entirely to the flower and fruit. It 
is essential, factitious, or natural ; which see. 

Gene'ric name. The name of a genus. Milne 
enumerates 21 rules respecting the naming of ge- 
nera ; which with his examples, occupy 40 pages. 
The principal names are founded upon some sup- 
posed virtues of plants, expressed in Latin or 
Greek — the habit, place of growth, &c. express- 
ed in the same manner — given in honour of some 
distinguished botanist — or borrowed from the fa- 
bles of poets. 

It seems to be an established modern rule, that 
no genus shall have the name of a politician, or 
©f any other character however distinguished. 

GEN 89 

unless liberal patronage, or skill in the science of 
Botany, will warrant it. 

Geniculate. Kneed. Forming a very obtuse an- 
gle, like a moderate bending of the knee. 

Gen'tes. Nations. Linneus divided plants into nine 
great natural tribes or casts. 1. Palms (palmac ;) 
as the date and cocoa-nut. 2. Grasses (gramina ;) 
as Wheat, Indian-corn, sugar-cane, rice, timothy- 
grass, &c. 3. Lilies (lilia;) as lily, tulip, daffo- 
dil, &c. 4. Herbs (herbae ;) as thistles, nettles, 
pease, mint, potatoes, hemp, plantain, beets, and 
all other herbaceous plants except the above. 5. 
Trees (arbores ;) as oak, chesnut, pine, willow, 
dogwood, currants, lilac, whortleberry, cranberry, 
and all other plants with a woody stem. 6. Ferns 
(Alices ;) as brake, polypod, maidenhair, ground 
pine, and all other plants of this order, which see. 
7. Mosses (musci.) See the order. 8. Alg*:. 
This tribe includes the plants of the orders, he- 
paticce, alga and lichenes, which see. 9. Fungi. 
As mushroom, toadstool, puff-ball, mould, blight, 

Ge'nus, (plural gen'era.) A number of plants which 
agree with one another in the structure of the flow- 
er and fruit. — Willdenow. The classes are divided 
into orders, and then the orders are divided into 
genera, the genera into species. This is the ana- 
lytic method. The species are united into their 
respective genera by rejecting the specific dis- 
tinctions; genera are united into their respective 
orders, by rejecting the generic distinctions ; or- 
ders are united under their respective classes by 
rejecting (he taxinal character. This is the syn- 
thetic method. Thus it will be readily perceived, 
that scientific botany is practical logic. 
Plants of the same genus possess similar medical 

90 G L A 

powers, though in very different degrees. — Milno. 
This rule is certainly liable to some exceptions 

Germ, ger'men. That part of the pistil, which, after 
the pollen is received, soon contains the rudimen' 
of one young plant, or more. Its whole substance 
becomes the pericarp and seed, as it enlarges itself. 
When the calyx comes out below the germ, the 
germ is superior, and the calyx inferior ; when the 
calyx comes out of the upper part of the germ, the 
germ is inferior, and the calyx superior. 

The mirabilis and sanguisorba, have the germ 
between the calyx and corol. But Smith says, 
the corol can be traced to the base of the germ in 
the sanguisorba ; and Dr. Ives showed trie wri- 
ter of this article a sanguisorba media wherein he 
had distinctly separated the corol from the germ 
entirely to its base. It is therefore very doubtful, 
whether there is a plant, whose germ is between, 
the calyx and corol. 

Ger'minate. Appertaining to the germ. 

Germina'tion. The swelling of a seed, and the un- 
folding of its embryo. 

Gib'bous. Bunched out. When one or both sides 
are swelled out. 

Gills. See lamella. 

Gil'vus. Iron-grey. 

Glabel'lus. Bald. Without hairs. 

Gla'brous, glab'er. Sleek. Having no pubescence. 
Glaber is often translated smooth, which in most 
cases conveys a correct idea ; or at least does not 
lead to error. But a leaf with soft cottony pubes- 
cence is smooth, though it is not glabrous. 

(iladia'ius, A Sword-form legume is sometimes 
called gladiate. See ensiform. 

Gland, glan'dula. A round, or roundish appendage 
^hich serves for transpiration and secretion. 

G L O oi 

They are situated on leaves, stems, calyxes, and 
particularly at the base of stamens in some cruci- 
form flowers; as mustard. Glandular hairs, or 
hairs with glandular heads, are very abundant oa 
the common hazlenut calyx of North America, 
(corylus americana.) 

Glan'dular, Glan'dulous, glandulosus. Havinc 

Glandulif'erous. Bearing glands. 

Glass'-form. See Cyathiform. 

Glas'sy. See hyaline. 

Glau'cous. Clothed with a seagreen mealine3s, 
which is easily rubbed off. It is sometimes put 
for a greenish-grey colour. This colour, ferru- 
ginous and hoary, are so constant, that they are 
used in specific descriptions. All other colours 
are excluded on account of their being too varia- 
ble to be relied on. 

Globo'se, Globo'sus. Spherical, round on all sides 
like a ball. This term is often applied in cases 
where the part is rather roundish than perfectly 

Glob'ules. That kind of receptacle of lichens, 
which is globose, solid and crustaceous, formed of 
the substance of the frond, and terminating its 
points or branches ; from whence they fall off en- 
tire, leaving a pit or cavity. They are supposed 
to be covered all over with a coloured seed- bear- 
ing membrane. Smith. 

Glob'uli. Globules. 

Glo'chis. See barb. 

Glome. A roundish head of flowers. 

Glom'erate, glomera'tus. When many branchlets 
are terminated by little heads — Richard. A spike 
is glomerate when it consists of a collection oi 
sperical heads — Willdenow. 

92 G R A 

Glom'erule, glomerulus. The small heads consti 
tuting a glome, or a small glome. 

Gluma'ceous. Glume-like, or bearing glumes. 

Glume, glu'ma. Consists of the scales or chaff; 
which surround or enclose the stamens and pistils 
in the flowers of grasses. The outer ones are 
called the calyx, the inner ones the corol. 
- Each scale, chaff, or husk, is called a valve ; 
which gives the names bivalve, with 2 husks or 
chaffs ; univalve, with one, &c. 

When several flowers are arranged along a ra- 
chis in a spikelet with a valve or two, or more, 
below the lowest flower, these are called the com- 
mon or general calyx (gluma communis ;) and the 
glume to each floret on the spikelet above is 
called partial (gluma partialis.) 

Richard says, glumes ought to be called bracts ; 
as they are not properly either calyx or corol. 

Glumo'se. Having glumes. 

Glu'tinous. Having on some part more or less of 
adhesive moisture. 

Gnaw'ed. See erose. 

Gon'gulus. A knot. It is applied to a round, hard 
body, which falls off upon the death of the mother 
plant, and becomes a new one ; as in the fucus. 

Gonop'terides. Angle-fruit fern. One of the new 
orders of Ferns. It is adopted by Pursh, Tor- 
rey, and a few other writers on American botany. 
The receptacles of the fruit are polygons ; as of 
the genus Equisetum. 

Gram'ina. The family of grasses. See gentes. 
But in a limited sense, the sedges, rush-grasses, 
&c. are not included. See Natural Orders. Cul- 
miferous is the most extensive term; and most of 
this vast family have three stamens in each flower, 

GYN 93 

though many of them are monoecious. The rice, 
star- grass and rush-grass have six stamens to the 

Graminifol'ius. Having leaves resembling those of 

Grandiflo'rus. Having large flowers. 

Granif'erus. Bearing grains or kernels ; as those 
on the valves of dock-flowers. 

Gran'ulate, granula'tus. In the form of grains. 
A granulate root consists of several little knobs 
strung together along the side of a filiform radicle. 
It differs from the knobbed tuberous roots in this ; 
that the latter are strung together by rootlets 
which proceed from near the middle of one knob 
to another. 

(jranula'tions. Grain-like substances. 

Grave'olens. Having a strong odour or scent. 

Groov'ed. See sulcate. 

Grossifica'tion. The enlarging of the fruit afic; 
the florescence. 

Guitar'-torm. See panduriformis. 

Gymnocar'pi fun'gi. Such as bear seeds in a naked 
hymeniam, which see. 

Gymnosper'mus. (Gumnos, naked ; sperma, seed.) 
With seeds naked, or growing without pericarps. 

G YMNOSPER'MIA. The name of the first order in 
the class didynamia. It includes those plants, 
whose seeds have no pericarps ; as mint, mother- 
wort, pennyroyal, hyssop, catnip, thyme, heal-all, 
&c. The rudiments of the four naked seeds may 
be seen around the base of the pistil, as soon as 
the flower opens. 

GYNAN'DRIA. (Gune, female ; aner, male.) Sta- 
men and pistil united. The name of the 20th 
class, or of the 1 9th if the 1 8th be rejected. It in- 
cludes all plants whose stamens are inserted on 

94 H A M 

the germen, style, or stigma, separate from the 
base of the corol. Formerly plants were placed 
here, as the passion flower, &c. whose stamens 
were attached to an elongated receptacle. 

The pollen in most plants of this class is glutin- 
ous. Many of them have the anther on a movea- 
ble lid on the top of a style. Plants formerly in 
the second order of this class are mostly removed 
to the first by Swartz. What was formerly consi- 
dered as two anthers is founrUo be 2 cells of one 
anther. The pollen is often in stalked masses, 
which might appear to a student like so many an-

situation wherein they grow most naturally. 

Hab'it, hab'itus. The external appearance of a 
plant by a general view of which we know it with- 
out attending to any of its essential characters. 

A knowledge of the habit of plants is to be 
acquired ; by first seeing them in a growing state, 
and then by repeatedly reviewing them in an her- 
barium, which see.

ven-stamened. The name of the seventh class. 
It comprises all the plants whose flowers are per- 
fect, with 7 stamens in each. 

It may also become the name of the seventh or- 
der in those classes where the characters of the 
first 13 classes are taken for orders should future 
discoveries require it. See enneandria. 
Heptan'drous. Belonging to, or varying into, the

Herb'age. All that part of a vegetable which is 
bounded by the root below, and by the fructifica- 
tion above. It comprises all parts of every plant, 
except the root and fructification, whether herba- 
ceous or woody. See partes. 

Herba'rium. A collection of dried plants. No 
person can ever become a good practical botanist 
without an herbarium. See habit. A man of 
science may acquire a knowledge of the physiology 
of plants-, and obtain a general view of the science 
of botany from books. But to become a practi- 
cal botanist, so far as to be able to apply the 
principles of the science to any useful purpose, 
an herbarium is essential. 

The uses of an herbarium are principally these : 

1. To acquire a knowledge of plants. Any per- 
son of either sex, who is desirous to know the 
names of all the plants in any neighbourhood, 
(which in the compass of three or four miles, will 
amount to 6 or 7 hundred species in most parts of 
North America, exclusive of cryptogamous plants) 
should make an herbarium according to the fol- 
lowing directions. Let this be sent to the near- 
est practical botanist ; who will readily annex to 
each its generic and specific name. Make an in- 
dex to these names ; and frequently look over the 
plants and compare others with them, in a grow- 
ing state ; which is all that is required to obtain 
the object desired. 

2. To revive in the memory the names and habits 
of plants. No memory is sufficiently retentive to 
permit nothing to slip, relating to several hundred 
species of plants ; unless they are frequently pre- 
sented to the eye. 

3. When plants are not in flower, they often 
want some of their most striking habits also, it is 

HER 97 

.herefore very convenient and satisfactory to com- 
pare the more minute parts, in order to insure cor- 
rectness in relation to plants, which we have oc- 
casion to examine at various seasons of the year. 

Directions for making an herbarium. 

Those, who are desirous to know all the various 
modes of performing this interesting task, are re- 
ferred to Smith's Elements, page 504. Willde- 
now's Principles, p. 4. Richard under the word 
herbier. But the object of the author being to 
give an account of the most simple and conven- 
ient method ; a detail of the various plans pro- 
posed will not be proper here. 

1. Provide yourself with about 100 old news- 
papers ; or other coarse paper about equal to that 
in quantity and texture. Let these papers be 
very thoroughly dried. This will be a sufficient 
stock for the season. 

2. Procure two smooth inch-boards of the size 
of half of a paper; also a weight of lead, stone, 
or other substance, of twenty pounds. 

3. Gather 3 or 4 specimens of each plant, as it 
comes in flower. If you collect but few speci- 
mens, and wish to preserve them in the most beau- 
tiful form, put them between the leaves of a port 
folio in the field. Let the specimens be so large 
as to include the various parts of the plant. If it 
be a small plant, take the root also. If large 
take it in two pieces ; one to include the flower 
and parts adjoining, the other the root-leaves, if 
any, and those near the root. Place these be- 
tween the folds of the papers, as nearly in their 
natural state as possible. If the plant curved, 
let it curve in the papers ; if the flower drooped 
in the field or woods, let it droop in the papers. 


&c. Lay the papers between the boards with 
the weight upon them. If 20 or 30 filled papers 
lie upon each other, it is all the same. 

4. Twice or three times each week lay your 
papers, containing plants, separately in the sun, 
with small stones on the corners, for three or four 
hours. When taken in, put them in press again. 
This exposure to the sun is not necessary, however, 
with single specimens of small plants. Or if seve- 
ral leaves of paper be allowed to each specimen. 

5. As fast as your plants become dry, put them 
jp in books made of the same paper, with about 
a dozen sheets in each. Most plants will be fit 
to put up, after sunning five times, and pressing 
two weeks. When the roots are taken up, if bul- 
bous, they should be immersed in boiling water, or 
they will be very long in drying. Most ever- 
greens and succulent plants, except aquatics, 
should be immersed in boiling water, or they will 
drop their flowers, &c. 

6. After the season is past, (which is about the 
end of November,) make a large book of stiff print- 
ing paper; and fasten one or more of your best 
specimens of each species to the first page of 
each leaf. Put as many specimens on a leaf as 
will fill it up ; leaving room for names, &c. under 
each. Some glue them on ; others cut through the 
papers and raise up slips, like loops, and run the 
specimens under these loops. The latter method 
is best and cheapest. 

Your herbarium will now be ready to send to 
the practical botanist, as before mentioned. 

It may be proper to observe, that if a long sea- 
son of wet weather occur, or if you have not time 
or convenience for drying your papers in the sur. 
while containing the plants, you may effect the 

HEX 99 

same object by drying other papers thoroughly by 
a fire, and then shifting your plants into them. 

Plants should never be dried so as to become 
brittle. They should resemble the state of well 
dried hay. The object in drying them between 
papers is ; to prevent their crisping, and to retain 
more of their natural colour and texture, than can 
be done openly. But still many plants cannot 
possibly be made to retain their natural colours. 
Simple and woods flowers abound in the fore 
part of the season ; compound and field flowers 
come most after the middle of July. An indus- 
trious collector will have 400 species by the first 
of July ; and will find 250 species afterwards, 
before the season closes. See efflorescentia, tem- 
perature, and species. 

Hcrba'rius. An herbist. One who collects and sells 

Hermaph'rodjte. See perfect. 

Hexag'onal, hexago'nus. Six-cornered. 

HEXAGYNM. (Hex, six ; gune, female.) Six- 
styled. The name of the sixth order in each of 
the first thirteen classes. Plants of either of these 
classes with six styles or sessile stigmas are of the 
6th order of such class ; as Wendlandia is of the 
6th order of the 6th class. 

HEXAN'DRIA. (Hex, six ; aner, male.) Six-sta- 
mened. The name of the sixth class. It com- 
prises all plants, whose flowers are perfect; with 
six stamens in each, not united by their filaments 
in one or two sets, nor regularly with 4 longer 
than the other 2. Liliaceous plants belong here. 
It is also the name of the 6th order in those 
classes, where the characters of the first thirteen 
classes are taken for orders ; as fumaria and cory- 
dalis in the class diadelphia, aristolochia (birth- 

100 HOO 

wort) in the class gynandria, wild-rice (zizania) 
in the class moncecia, green-briar (smilax) in the 
class dicecia.

stifTish hairs, but hardly stiff enough to be called 

llir'tus. Covered with short stiff hairs. Nearly the 
same as hirsute. 

His'pid, His'pidus. Bristly. Beset with stiff hairs, 
or rather with bristles, which are very short. 
Perhaps it differs from hirtus only in having the 
hairs shorter and sliffer. It seems to be applied 
in some cases, however, where the bristles are 
not very short. 

Hiul'cus. Cracked open ; a gaping chink. 

Ho'ary. Whitish coloured, arising from a scaly 
mealiness. See glaucous. 

Holera'ceous. Suitable for a pot-herb. 

Hoi/lows, (thalamia.) That kind of receptacle of 
lichens, which is spherical, nearly closed, lodged 
in the substance of the frond, lined with its pro-

glass or water. 

Hyber'nicle, hybernac'ulum. See bud. 

Hyberna'lis. Growing in the winter season. 

Hy'brid, hy'brida. A mule. A vegetable produc- 
ed by the mixture of two different species. The 
seeds of hybrids will not propagate. They are 
produced by sprinkling the stigma with the pollen 
of a different species. Care must be taken in 
such cases to prevent any pollen of its own spe- 
cies from falling on it first. 

IIydrop'terides. Water fern. A new order of 
Ferns. It is adopted by Pursh, Torrey, &c- 
Isoetes, Azolla and Salvinia are placed here.

ICOSAN'DRIA. (Eikosi, twenty; aner, male.) 
Tvventy-stamened. The name of the 12th class. 
It comprises all plants, whose flowers are perfect, 
with 20 or more stamens growing on the inside 
of the calyx, not on the receptacle. Some au- 
thors say, any number of stamens over 12, pro- 
vided they grow to the calyx. Lithrum, however, 
has the stamens on the calyx ; also agrimonia, and 
they are not always constant in the number of 
stamens. Perhaps the better way is to leave this 
class as Linneus left it; and annex the genera, 
which vary from it, to the end of orders in the 
usual way. 

The calyx is always monophyllous and the 
claws of the petals fixed into the inside of it along 
with the stamens. 

Icosan'drous. Belonging to, or varying into, the 
class icosandria. 

Jc'terus. The change of colour in leaves in autumn. 

Jmber'bis. Beardless. See beard.

Inca'nus. See hoary. 

Incama'tus. Flesh-coloured. 

Inci'sed, Inci'sus. Cut in like a gash with a knife,

crenatures or serratures of a leaf are cut down, to 
appearance, with a slit or gash, this term applies. 

Incli'ned, inclina'lus. Bent towards each other. 
Also bent towards something different. 

Inclu'ding, inclu'dens. One thing containing an- 
other within it ; as the calyx shutting up the seed, 
capsule or corol.

zontally upon the top of the filament. 

Incur'vep, incurva'tus. Bent inwards. As a leaf 
bent in at the point towards the stem, a filament 
towards the pistil, a prickle towards the stem. 

104 INP 

Indig'enous. Plants, growing naturally and origi- 
nally in a country, are indigenous to that coun- 
try. It is often very difficult to determine, whe- 
ther a plant is exotic or indigenous. Who can 
say, whether the chess (bromus secalinus) stone- 
seed (lithospermum arvense) and cockle (agros- 
temma githago) are native or exotic ? 

Jndivi'sus. Undivided. Not cleft into parts. It 
may however be serrate, crenate or toothed ; it 
is therefore not the same as entire. 

In'durated, indures'cens. Becoming hard, lough, or 

Indu'sium. A shirt. It is used by some authors for 
the thin membranous covering on the fruit of ferns. 
But Smith prefers retaining the old name, involu- 
cre, which see. 

Iner'mis. See unarmed. 

Infer'ne. Downwards. Towards or near the base 
or root.

Intor'sion, intor'sio. Twisting, twining or bending 
from a strait upright position. See twining con- 
torted and twisted. 

Intor'tus. Twisted inwards. 

I.vtrafolia'ceous. Within the leaf. A stipule is 

intrafoliaceous, when it originates a little above 

the origin of the petiole, which brings it, as it 

were, within the bosom of the leaf. 

Introduced. Not originally native. Brought from 

some other country. 
Intror'sum. Inwardly. 

106 I R R 

Inversely heart'-form. See obcordate. 

Inunda'lus. See submersus. 

Involu'crate. See involucred. 

Involucre, involu'crum. That kind of calyx which 
comes out at a distance below the flower, and ne- 
ver encloses it like the spathe. It is further dis- 
tinguished from the spathe in being of a leafy tex- 
ture and colour, whereas the spathe is generally 
membranaceous or coloured. It is generally 
found at the origin of the peduncles of umbels ; 
and sometimes attached to other aggregate flow- 
ers. When it is all on one side it is called dimi- 
diate, halved. See partial. 

Involucres of ferns generally lie on the tops of 
the capsules, like a piece of linnen spread out to 
dry; hence they are called indusium, a shirt. 
They are denominated cornicidalum, when cylin- 
dric, hollow and enclosing the seed. 

Involu'cred, involucra'lus. Having involucres. 

Involu'cel. A partial involucre, or a little involucre.

like a rainbow. 

Irreg'ular, irregularis. Differing in figure, size, 
or proportion of parts, among themselves. 

Irritabil'ity. The power of being excited so as 
to produce contractile motion. That there is such 
a thing as vegetable irritability is evident to every 

KNO 107 

one, who examines the common barberry flower. 
Touch the inside of a stamen near its base with 
the end of a horse-hair, or any thing about the 
same size, and it will instantly strike its anther 
against the pistil and shoot a quantity of pollen 
upon the stigma, or in that direction. 

Ish. See Acutiusculus. 

Isthmus. Long narrow joints in legumes or loments. 

Jug'um. Yoke. In pairs.

Ker'nel. See nucleus. 

Kid'ney-form. Hollowed in at the base with round- 
ed lobes and rounded end. Its breadth is gene- 
rally, as great as its length.

Knobs. (Cephalo'dia.) That kind of receptacle 
of lichens, which is convex, more or less globular, 
covered externally with a coloured seed-bearing 
crust, and placed generally at the extremities o! 
stalks, originating from the frond, permanent: 
rarely sessile. Sometimes they are at first span 
ghs on rilauientous lichens, and afterwards be- 
come convex irregular knobs. They are simple, 
compound or conglomerate. Smith,

Knot. A swelling joint. See joints. 

Knot'ted. Having swelling joints. 

Knot'less. Without swelling joints. See enodc. 


La'biate. Having lips ; or a calyx or corol divid- 
ed at top into two general parts, somewhat re- 
sembling the lips of a horse or other animal. 

Labiate corols are divided into ringent and per- 

Eingent, such as have the lips open or gaping. 
Personate, such as have the lips closed or muffled. 

Lahyrinthifor'mis. Winding and turning by various 
involutions and contortions like a labyrinth. 

Lac'erated, lac'erus. Torn. Cut, or apparently 
torn, into irregular segments.

Lax, lax'us. Limber. See flaccid. 

Leaf. That part of most vegetables, which pre 
sents more surface to the atmosphere, than all 
other parts ; and consists principally of the cellu- 
lar integument covered with the cuticle. Leaves 
imbibe and give out moisture; generally more 
with one surface than the other. Aquatic leaves 
perspire faster than dry-land leaves ; which is the 
reason for their drying so much sooner. Some 
leaves imbibe sufficient moisture from the atmos- 
phere for their support for a long time ; as the 
common liveforever will grow, if broken off and 
stuck up in a dry place. 

Leaves are divided into simple, when one leaf 
grows on one petiole ; and compound when seve- 
ral leafets grow on one petiole. 

They are ev'ergreeti, remaining through the 
"winter *, or deciduous, falling off at the close of the 

They are farther distinguished by their forms, 
surfaces, and positions. All of which are describ- 
ed under their peculiar names. 

Le'afing season. That time in the year when 
most leaves come out. In North America the 
proper leafing season is in April. 

Le'afet, or le'aflet. One of the lesser leaves 
which, with others, constitute a compound leaf. 
A simple leaf is never a leafet, however small. 

Le'afless. Destitute of leaves, naturally. This 
term does not apply in cases of defoliation, which 

Le'af-stalk. See petiole. 

Le'afy. Furnished with leaves. Abounding

L I G 111 

Leathery. See coriaceous. 

Legume, legu'tnen. A pod, without a longitudinal 
partition, with its enclosed seeds attached to one 
suture only ; as the pea. Those with tranverse 
partitions are usually called loments, which see.

plied to a kind of glandular roughness on the sur- 
face of some plants. Form of a convex lens.

LICHENES. See cryptogamia. 

Lid of mosses. See operculum. 

Light. Various motions and inclinations of plants 
prove the effect of light upon them. Trees pre- 
sent their leaves outward in quest of light, be- 
cause it is darkest in the centre. Plants in a 
green-house all present the upper surfaces of their 
leaves towards the enlightened side of it. Wheat- 
heads hang towards the sun. Most compound 
flowers follow the sun through the day. Plants 
deprived of the light lo6e their green hue ; as po- 
tatoe tops growing in a dark cellar. 

Ligno'se, ligno'sus. Woody. 

Lig'num. See wood. 

Lig'ula. A strap or strap-form organ. It is gene- 
rally applied to the membrane or stipule at the

compound flowers, which consists of a single 
strap-like petal which becomes tubular at the base

tal of a monopetalous corol. 
Line, li'nea. The breadth of the crescent at the

a cleft incision, except by its being larger. 
Lo'bed, loba'tus. Divided into lobes. Deeply part- 
ed, with the segments distant or spreading and

Meas'ures. Proportion between parts is better than 
any measure. But when measures are adopted, 
they should be taken from parts of the hand and 
arm. Because the parts of plants vary about as 
much as the hand ; and in adopting these mea- 
sures the same allowance should be made. 

1. Line, the crescent at the root of the nail. 
About one-twelfth of an inch. 2. Nail (unguis.) 
Length of the nail. About half an inch. 3. Inch 
(pollex.) Length of the first joint of the thumb.

inches. 5. Short'-span (spithama.) Distance be- 
tween ends of thumb and fore-finger. About 7

Medic'inal, medicina'lis. Plants possessing princi- 
ples sufficiently active to entitle them to a place 
in the materia medica. Many physicians dai- 
ly trample under foot plants, which possess si- 
milar qualities with those which they purchase 
from Europe, and often the very same plants ; but 
being ignorant of those botanical principles by 
which the names and properties of plants are as- 
certained, they are consequently ignorant of the 
absurdity. See qualities. 
Medio'cris. Averaging in dimensions compared with 

other parts. See relative proportions. 
Med'ius. In the middle. This term is used when 
one part is between the other parts, though some- 
times much nearer one than the other ; as a bract is 
in the middle of the peduncle, when it is much near- 
er the flower than to the base of the peduncle. 
This name is sometimes given to species holding 
a middle place between extremities, expressed 
by the names of other species of the same genus. 
Medulla. See pith. 
Mellif'erous, mellifera. Producing or containing 

Melli'go. Honey-dew on leaves. 
Membranaceous. Made up, apparently, of the two 
plates of the cuticle, without any cellular integu- 
ment between them. Nearly transparent, very 
thin and colourless. 
Membrana'tus. Flattened and resembling a mem- 
Mensu'ra. See measures. 

Meth'od, method'us. A mode of arranging plants 
in classes, orders, &c. Richard has 14 pages on 
this head \ in which he gives the methods of Tour- 

1I6< MON 

nefort and Linneus at length. But as we have 
given the method of Linneus under Systematic 
Terminology, and throughout the Dictionary ; and 
as Tournefort's method is no where adopted in 
this country ; this article is principally omitted. 
It may be observed that : 

Tournefort's method 
Divides plants into herbs and trees. The Herba- 
ceous plants are divided into 17 classes. Four- 
teen of these are distinguished by the form of the 
corols ; as, 1 . Infundibiliformis. 2. Personate, 
&c. The other 3 classes are apetalous and dis- 
tinguished by having stamens, no apparent flowers, 
and no apparent seed. The Tree kinds are di- 
vided into 5 classes. 

Mid'rib. The main or middle rib of a leaf running 
from the stem to the apex. 

Milia'ris. In the form of millet seed. 

Minia'tus. Scarlet, vermillion colour. 

Minutis'simus. Extremely small or minute. 

Mi'tre-form. Terminating in two divisions, in 
some measure resembling a bishop's mitre. 

Molendina' cea. Many winged. 

Mollis. Seft. 

MONADEL PHIA. (Monos, one ; adelphos, bro- 
ther.) One brotherhood. The name of the 1 5th 
class. It comprises all plants, whose flowers are 
perfect with the stamens united by their filaments 
in one set and the flowers not papilionaceous. 

It is also the name of ihe 16th order in those 
classes, where the characters of the first 1 3 classes 
are taken for orders. Though this is not of the 
first 13 classes, yet it is adopted upon the same 
principle in the class monozcia and diozcia ; as the 
pine, white-cedar, cucumber, squash, &c. in the 
former j and red-cedar, yew, &c. in the latter. 

MON 117 

Monadel'phous. Belonging to, or varying into, the 
class monadelphia. 

MONAN'DRIA. (Monos, one ; aner, male.) One- 
stamened. The name of the first class. It com- 
prises all plants, whose flowers are perfect, with 
one stamen in each, not growing on the pistil. 

It is also the name of the first order in those 
classes, where the characters of the first 13 classes 
are taken for orders ; as the orchis and arethusa 
in the class gynandria. 

Monil'iform. See granulate. 

Monocotyle'dones. See cotyledon. 

MONCE'CIA. (Monos, one; oikos, house.) The 
name of the 21st class ; or the 20th, if the 18th 
be rejected. It includes those plants whose flow- 
ers are not perfect, but the stamens and pistils 
grow in different flowers on the same plant. As 
in the Indian-corn, the stamens are in the tassels, 
and the pistils are the silks of the ear. 

Monoecious, monoi'cus. Belonging to, or varying 
into, the class moncecia. 

MONOGYN IA. (Monos, one ; gune, female.) Onc- 
pistilled. The name of the first order in each of 
the first 13 classes. It comprises all plants in 
each class, respectively, whose flowers have one 
style in each ; or, if the style is wanting, one ses- 
sile stigma; as samphire (salicornia) in the class 
monandria, lilac (syringa) in diandria, Iris in 
triandria, plantain in tetrandria, mullein in penlan- 
dria, lily in hexandria, horse-chesnut in heptandria, 
laurel (kalmia) in dccandria, purslane in dodecan- 
dria, cherry in icosandria, poppy in poly andria. 

Moxopet'alous. The whole corol in one piece. 
Sometimes it is so deeply parted, that it appears 
to be polypetalous until it is pulled off and close- 
ly examined at the base. In most monopetalous 

118 MUL 

corols, the stamens are attached to the tube. They 
are divided into Bell-form, Funnel-form, Salver- 
form, Wheel-form, and Labiate, which sec. 

Monophyl'lous. (Mon'os. one ; phullon, a leaf.) 
One-leafed. A calyx all in one piece. All the 
calyxes in the class icosandria are of this kind. 
They are often so deeply divided, that a student 
may mistake them for polyphyllous, without par- 
ticular attention. 

Monopteryg'ia. See wings. 

Monopyre'nus. Enclosing but one nut or stone. 

Monosper'mus. One seed to a flower. 

Monoslac'hyos. (Monos, one ; stachus, spike.) Sin- 
gle spiked. 

Mon'strous. Plants producing any part different 
from the same part, when growing wild. As the 
rose has but five petals in a wild state ; but, by 
rich cultivation in gardens, the stamens are most- 
ly changed to petals. Carnations and peony are 
examples also. These are all monsters. See 
florist and full-flowered. 

Monta'nus, Growing most naturally on mountains. 

Moon-form. See crescent-form. 

Mos'ses. See musci. 

Mouth. See faux. 

Mu'cidus. Resembling mouldiness, or mucor.

Natural class. See natural orders. 

Nat'ural his'tory. That department of Science, 
which treats of the productions of nature as they

decomposition or chemical analysis. 

It is generally divided into four branches. 

1. Zool'ogy. Which includes all animals ; as 
Beasts, Birds, Reptiles, Fishes, Insects, Snails, 
Clams, Worms and Corals. 

2. Bot'any. Which includes all plants. As 
Palms, Grasses, Lilies, Herbs, • Trees, Ferns, 
Mosses. Liverworts, Seaweeds and Mushrooms. 

3. Mineral'ogy. Which includes the unorga-

salt, Flint, Lime, Clay, Iron-ore, Silver-ore, Lead- 
ore, with the ore of 26 other metals, &c. 

4. Aerol'ogy. Which includes the atmosphere 
and whatever floats in it. This takes in the natu- 
ral history of lightning, meteors, &c. But it is 
more particularly concerned with clouds as it re- 
spects systematic arrangement. 

Nat'ural Orders. An arrangement of plants ac- 
cording to their natural affinities, without regard- 
• ing their artificial characters. Such an arrange- 

NAT 121 


saent is of great use both in finding out a plant, 
and examining its relations and qualities. 

Ft is considered advisable to insert here the two 
celebrated systems of Linneus and Jussieu. For 
this Dictionary is intended as an assistant in read- 
ing any system, which may fall into the hands of 
a student; and after he has found out a plant, he 
may be desirous to examine it by these systems. 

Linneus supposes, (Rose, Milne and others fol- 
low his opinions, and Cullen in some measure,) 
that plants of the same natural order possess si- 
milar medical qualities. But the scent of plants 
must certainly be taken into consideration ; as 
all nauseous-scented umbelliferous plants are poi- 
sonous, while the sweet-scented are pleasant sto- 
machics, &c. See qualities. The medicinal qua- 
lities are annexed from Milne, Woodville, Thorn- 
ton and others, that the student may avail him- 
self of whatever advantage can be derived from 
such natural affinities. " Several plants charac- 
terized by a particular virtue, possess it to such 
a degree of strength or weakness, that we may 
reasonably expect very different effects from this 
difference of intensity in the same quality ." Milne.

Natural Orders of Jussieu. 

Jussieu's System is a very great improvement 
upon that of Linneus. But I have seen no attempt 
at giving the medical qualities of each order. Ac- 
cording to the maxim of Linneus and others, the 
student has only to acquaint himself with the vir- 
tues of one or two plants in order to be able to 
form some general opinion of all other plants in 
that order. 

1st Division. Seeds without lobes or cotyledons. 

1. Fun'gi. All fungusses. As Mushroom, 
Toad stool, Puff-ball.

Phanerog'amous, Phcenog'amous. Having the sta- 
mens and pistils sufficiently apparent for classifi- 
cation. Applied to all plants, not included in (he 
class cryptogamia. M'Bridc. 

Though phanerogamous is correctly derived 
from phaneroo, to make manifest ; yet as phenoga- 
mous (of phaino, to shew,) is perfectly appropri- 
ate, there seems to be no necessity for encumber- 
ing the language of botany with another term of 
greater length. Ives. 

Phami'ceus. Purple, dark-red. 

Phytol'ogv. (Phule, a plant ; logos, a treatise or 
discourse.) The science which treats of the prin- 
ciples of vegetables. It is nearly synonymous 
with (he physiology of vegetables. 

Pic'eus. Blueish-black, resembling dark pitch. 

P ileus. The hat of a fungus. The top and most 
spreading part. It may be without stype, and 
thus constitute the whole ascending part. It al- 
ways contains the seeds, though it requires the 
highest magnifiers to discover them in most cases. 

Pilid'ia. See puffs. 

Pilif'erous. Bearing hairs. 

Pilo'se, pilo'sus. Hairy. Having distinct straitish 
hairs. Pappus is pilose, hairy or simple, when 
each hair is without any lateral branches. See 

Pil'us. A hair. An excretory duct of a bristly 
form, leading off a fluid. See sting. 

Prit'PLED. See papulose. 

P i T 145 

Pinna. A wing-feather. It is applied to leafets, 
which resemble feathers by their positions. 

Pin'nate, pinna'tus. Winged, or feathered. Leaves 
are pinnate, when distinct leafets are arranged 
along opposite sides of a simple petiole. Sec 
bipinnate and tripinnate. 

Pinnat'ifid, pinnalif'idus. Cut-winged. Leaves 
are pinnatifid, when, instead of leafets as in pin- 
nate leaves, segments or divisions of a leaf are 
along opposite sides of the midrib. Pinnate are 
compound, but pinnatifid are simple ; because the 
divisions never reach the midrib. When pin- 
natifid leafets are on a pinnate leaf, it is called 

Pis'tillate flower. Having pistils only, without 
stamens ; as the flower of the fertile cucumber. 

Pis'til, pistil'lum. The central organ of a perfect 
flower. It generally consists of the germen, style 
and stigma. But the style is frequently wanting; 
then the stigma is seated on the germ, or sessile. 
The stigma receives pollen from the anther, and, 
in some manner not yet discovered, fertilizes the 
germ. Without this operation, no perfect seeds 
are produced. See flower, style and stigma. 

Pistillif'erus. See pistillate. 

Pitch'er-form. See urceolate. 

Pith. The spongy substance in the centre of the 
stems and roots of most plants. Most woody 
stems have no appearance of a pith after they be- 
come old. 

Pits, (cyphellae.) That kind of receptacle of lichens, 
which consists of open, cup-like, naked, white or 
yellow little spots, on the under side of the frond ; 
which is generally downy. They are at first im- 
mersed, globose, minute dots, which at length burst 
with an irregular margin, and discharge a powder. 

P O I 

Pit'ted. See lacunose. 

Placenta. Fleshy receptacle. 

Placenta'tion. The disposition of the cotyledons 
in the germination of the seeds. 

Plaited. Folded somewhat like a fan, when nearly 
full spread. In foliation it is more closely folded. 

Plane. Flat, with an even surface. 

Pla'no-con'vex. Convex or roundish one side 
and flat the other. 

Plant. Any substance growing from seed. As 
trees, grass, puff-ball, mould. See vegetable.

Plu'rimus. Very many. 

Pod. That kind of pericarp which is composed of 
two valves with the seeds attached to one or both 
sutures, or a longitudinal partition at the edges im- 
mediately adjoining the sutures. The pod is 
either a legume or silique. 

Pede'tia. The peduncles of lichens, whether hol- 
low or solid. 

Poin'tal. See pistil. 

Poi'sons. The definition of poisons and the man- 
ner, of their operation has not yet been satisfac- 
torily made out. It will here be no farther no- 
ticed, than as it respects vegetables, and then not 

Poi'sonous Veg'etables. Persons of all descrip- 
tions have frequent occasion to make some use of 
plants, when they are not in a situation minutely 

P O I 147 

to investigate their nature and qualities. As many 
plants are narcotic and injurious to the human 
constitution, it is very convenient to have at 
hand, or in the memory, a few concise rules on 
this subject. The following have been selected 
with great care from the authors whose names 
are given at the end of each rule. 


Plants not poisonous. 

1. Plants with a glume calyx, never poisonous. 
As Wheat, Indian-corn, Foxtail-grass, Sedge- 
grass, Oats. Linneus. 

2. Plants whose stamens stand on the calyx, 
never poisonous. As Currant, Apple, Peach, 
Strawberry, Thorn. Smith, page 392. 

3. Plants with cruciform flowers, rarely if ever 
poisonous. As Mustard, Cabbage, Watercress, 
Turnip. Smith, page 487. 

4. Plants with papilionaceous flowers, rarely if 
ever poisonous. As Pea, Bean, Locust-tree, Wild- 
indigo, Clover. Smith, page 446. 

5. Plants with labiate corols bearing seeds with- 
out pericarps, never poisonous. As Catmint. 
Hyssop, Mint, Motherwort, Marjoram. Smith, 
page 434. 

G. Plants with compound flowers, rarely poison- 
ous. As Sunflower, Dandelion, Lettuce, Bur- 
dock. Milne. 

Poisonous plants. 

1. Plants with 5 stamens and one pistil, with a 
dull-coloured lurid corol, and of a nauseous sickly 
smell, always poisonous. As Tobacco, Thorn- 
apple, Henbane, Nightshade. The degree of 
poison is diminished where the flower is brighter 

148 POL 

coloured and the smell is less nauseous. As po- 
tatoes are less poisonous, though of the same ge- 
nus with nightshade. Smith, page 415. 

2. Umbelliferous plants of the aquatic kind and 
a nauseous scent are always poisonous. As Wa- 
'er-hemlock, Cow-parsley. But if the smell is 
pleasant, and they grow in dry land, they are not 
poisonous. As Fennel, Dill, Coriander, Sweet- 
cicely. Smith, page 416. 

3. Plants with labiate corols, and seeds in cap- 
sules, frequently poisonous. As Snapdragon, Fox- 

4. Plants from which issues a milky juice on be- 
ing broken are poisonous, unless they bear com- 
pound flowers. As Milkweed, Dogbane. Milne's 
Contortae and Lactescentia. 

5. Plants having any appendage to the calyx or 
'■orol, and eight or more stamens, generally poi- 
sonous. As Columbine, Nasturtion. Linneus. 

Most general rule. 

Plants with few stamens, not frequently poison- 
ous, except the number be five ; but if the number 
be 12 or more, and the smell nauseous, heavy 
and sickly, the plants are generally poisonous. 
Milne's Multisiliquce and Sapor. 

JVb/e. Many plants possess some degree of the 
narcotic principle, which are still by no means 
hurtful. But the use of such plants is to be de- 
ferred, till fully investigated. See qualities. 
Pol'len. Meal. The dusty or mealy substance con- 
tained in the cells of anthers. In the anthers of 
most of the plants in the gynandria class, the pol- 
len is glutinous. And even the dry pollen is al- 
ways moistened by a peculiar liquid on the stigma, 
before it fertilizes the germ. These dry globules 


always explode on touching the moist stigma. On 
being viewed through a magnifier, they are found 
of various forms. In the sunflower, it is a prick- 
ly ball ; in geranium, perforated ; in comfrey, 
double ; in mallows, a toothed wheel ; in violet, 
angular; in daffodil, kidney-form, &c. 

Pollin'ia. Rolls or masses of pollen, not included 
in cells of anthers of the common form and tex- 
ture ; as of the Orchis, Asclepias, &c. Nuttall. 

Pollimf'erous. Bearing pollen. 

POLYADEL'PHIA. (Polus, many ; adelphos, bro- 
ther.) Many brotherhoods. The name of the eigh- 
teenth class as first established by Linneus. This 
class includes all plants with perfect flowers, whose 
stamens are united by their filaments in three or 
more sets, or brotherhoods. As St. John's wort 
Orange, St. Peter's wort. This class is still re- 
tained by the translators of Linneus, Willdenow, 
and others. But it is rejected by Persoon and 
others, on account of the extreme uncertainty in 
its character. Very few species of the genera ar- 
ranged under it are constant in their character. Of 
the late American writers, Muhlenberg, Bigelow, 
and Elliot, have retained it ; Pursh, Nuttall, Bar- 
ton, the author of the American Genera, &c. have 
rejected it. 

Polyadel'phous. Belonging to, or varying into, the 
class polyadelphia. 

POLYAN'DRIA. (Polus, many ; aner, male.) 
Many stamened. The name of the thirteenth 
class. It comprises all plants, whose flowers ar^ 
perfect, with twenty or more stamens in each, 
growing to the receptacle. It is distinguished 
;"rom the 1 1th class by having more stamens, and 
:'rom the 12th by their not growing to the calyx. 
It is also the name of the thirteenth order in 
13 * 

150 POL 

those classes, where the characters of the first 
thirteen classes are taken for orders. But the 
character of the 13th class is not rigidly adhered 
to in this order. If the number of stamens ex- 
ceed ten, the plant is placed in this order. And 
those which are very variable in number are ge- 
nerally placed in it; as the Arum has sometimes 
G or 8 stamens. Some of the examples of this or- 
der are Mallows and Hollyhock in the class mo- 
nadelphia, Indian turnip, Oak, Chesnut, Button- 
wood in the class moncecia, Poplar in the class 
dice cia. 

Polyan'drous. Belonging to, or varying into, the 
class polyandria. 

Polycotyled'onous. Plants with more than two 
cotyledons. See cotyledon. 

I'OLYGA'MIA. (Polus, many ; gamos, marriage.) 
Many unions. The name of the twenty-third 
class as established by Linneus. It comprises all 
plants, which have some perfect flowers, and 
others which are staminate and pistillate, or both 
kinds. This class is divided into three orders. 
I. Moncecia, having perfect flowers and either 
•itaminatc or pistillate ones or both on the same 
plants. 2. Dicecia, having perfect flowers on 
<ome plants, and either staminate or pistillate 
lowers, on others of the same species. 3. Trice- 
cia, having perfect flowers on some plants, stami- 
nate on others, and pistillate on others of the 
same species. This class like the 18th, is abo- 
lished by Pcrsoon and others, and the plants un- 
ler it distributed among the other classes. Pre- 
sident Smith thinks it ought to be discarded. See 
page 485. 

Polyg'amous. Varying into, or inclining to, the 
class polygamic^ 

PR£ 151 

Polygo'nus. Many cornered, or many-angled. 
POLYGYN'IA. (Polus, many; gune, female.) 
Many-styled. The name of the thirteenth order 
in each of the first thirteen classes. Plants of 
either of these classes with any number of styles 
or sessile stigmas over 12, are of the 13th order of 
that class. But we have no writer on North Ame- 
rican plants, who has adopted the order Dodeca- 
gynia ; therefore we may here take this order for 
all plants in the first 13 classes, whose flowers 
contain over 10 styles or sessile stigmas. Exam- 
ples. Yellow-root in the class pentandria, Water- 
plantain in the class hexandria, Strawberry in the 
class icosandria, Crowfoot in the class polyandria. 
Polymorphous. Presenting various forms and ap- 
Polypet'alous. Many-petalled. If the corol con- 
sists of more than one petal, it is polypetalous. 
Polyphyl'lous. Many-leaved. A calyx of more 

than one distinct piece is polyphyllous. 
Polypre'nus. Enclosing more than one nut, or stone. 
Polysper'ma. Many-seeded. 
Polystach'ius. Many-spiked. 

Pome, po'mum. A pulpy pericarp without valves, 
which contains within it a capsule. See berry and 
note the difference. Apples, quinces, &c. are 
Pomif'erus. Bearing pomes. 
Po'rous, poro'sus. Full of holes, cellules, or tubu- 
lar openings. 
Porrec'tus. Lengthened out, stretched, straitened. 
Prn'cox. Rathe-ripe. Coming to maturity early in 

the season. Flowering before leafing.

bluntly, as if bitten off. As the root of the pe- 
date or birdfoot violet.

Q'ladrivascula'ris. Four cup-form cells. 

Qual'ities or plants. Richard says that plants of 
the same taste and odour, are generally possessed 
of similar qualities. Also that the smell and taste 
are always the same. He divides the odours of 
plants into, I. Fragrant. 2. Aromatic. 3. Am- 
brosiac (resembling amber.) 4. Alliaceous (resem- 
bling garlic.) 5. Fetid (asasafuelida,&c.) 6. Nau- 
seous (causing the stomach to heave.) As the fra- 
grant, the aromatic and ambrosiac, are always free 
from all hurtful qualities, and as the fetid and nau- 
seous are generally poisonous ; it seems that man- 
kind have in some measure an instinctive princi- 
ple by which food is to be selected. 

Quuter'nus. Four together in a whorl. 

Qui'nus. Five together in a whorl. 

Qui'nate, quina'tus. Five leafets on one petiole.

divided pedicels arranged along the sides of a 
general peduncle. As currants, grapes. 

Race'med, racemo'sus. Flowers in racemes. 

Rac'his, (Rachis, the back-bone.) The filiform re- 
ceptacle connecting the florets in a spike. As in 
wheat-heads. It is sometimes put for the midrib 
in ferns. 

Ra'dial. Belonging to the ray.

the margin of a compound flower. As the Sun- 
flower. See Compound.

Ray. The outer margin or circumference ol a 
compound flower. It is also applied to the pe- 
duncles and outer florets of an umbel ; particu- 
larly when they differ in any respect from the 
inner, or disk, florets. 

Ra'yed. Having rays. 

Receptacle, recepta'culvm. The base by which 
the other parts of the fructification are connected 
and supported ; being the end, or at the end, of 
the peduncle. It is considerably used in the 
generic characters of compound flowers ; but very 
little noticed in any others. Perhaps this part 
may hereafter be noticed on account of the change, 
it in some way produces on the vegetable secre- 
tions. Dr. Smith mentions the wholesomeness of 
some fruits, while the other parts of the plant are 
poisonous. See page 392. Every one has no- 
ticed the delicate flavour of the pond-lily, (Nym- 
phea odorata,) while all back of the receptacle is 
extremely different. Numerous similar instances 
may be cited to prove the very great change in 
some way effected by the receptacle. When 
»Persoon applies receptacle (receptaculum) to a 
capsule, he intends the columella. 

Recli'ned, reclina'tus. Bent down so that the apex

Reg'num vegeta'bile. The vegetable kingdom as tak- 
en into view with the animal and mineral. 

Regular, regula'ris. See equal. 

Rel'ative proportions. When dimensions are ex- 
pressed indefinitely, as long, very long, short, 
large, &c. such expressions are to be understood 
as long, &c. compared with the proportion which 
similar parts usually bear to other parts, in plants 
generally. But when such terms are used for spe- 
cific names, the proportion between the parts of 
species of the same genus, which were known 
when the names were given, are compared. Thus 
Kahnia latifolia has a broader leaf than Kalmia 
angustifolia ; but it has a narrow leaf compared 
with any species of trillium. 

Remo'te, remo'lus. See relative proportion. 

Re'niform. See kidney-form.

nearly strait to the margin. It is sometimes put 
for nerved.

Rig'id, rig'idus. Stiff, inflexible, or not pliable; 

or if attempted to be bent, will rather break. 
Rimo'se, rimo'sus. Chinked, abounding in cracks, 

as the outer surface of the pitch-pine tree. 
Ring. The band around the capsules of ferns, 
which is elastic. See exanulatus. 

It is also the thin membrane attached to the 
stem of; a fungus. When young it is attached to 
the pileus. It is erect when the upper edge is not 
fastened— inverse when the lower edge is not fas- 
tened— sm?7e, when it is attached by one Bide 
only— moMe, when it may be pushed up and

Sap. The watery ilaid contained in the tubes, and 
cellules of vegetables, which furnishes the means, 
or is itself, the support of their growth and life, 
;:nd their preservation from decay. That part of 
:he sap which supplies materials for the growth, 
foliage and fructification, evidently ascends by 
way of the cumb. See camb. But that, which 
fills the insterstices among the woody fibres, and 
serves to preserve them from decay, is probably 
raised by capillary attraction. Freezing and 
thawing in some way or other suspends for a day 
or two the effect of capillary attraction. It then 
descends by its natural gravity ; at which season 
only can the sap be obtained from the sugar ma- 
ple. That it descends is evident from the fact, 
that no sap is obtained from below the incision, 
except a few drops at the first moment alter it is 
made. That the sap descends from the woody 
fibres and not from the camb appears from inspec- 
tion. That this sap serves only to preserve the 

S C A 16* 

wood appears from the rapid decay of the wood 
in the sugar maple directly above the incision 
to the whole extent of the bole ; while the in- 
cision produces but little effect below it. And 
the herbage of the tree with the outer layers 
of wood continue as flourishing after the tree has 
been drained of its sap annually for half a centu- 
ry, as its neighbours, which have never lost any 
sap. It may be observed further ; that sap can 
never be drawn from the same vessels above the 
incision where it has been drawn in any preced- 
ing year; unless a new incision be made several 
feet above the old one. Nor even then if the pre- 
ceding draining had been very considerable ; or, 
in other words, if the sugar-making season had 
been very favourable, and the incision large. 

Sapin'dus. Having some kind of taste. 

Sap'or. Having a relish, pleasant tasted, any taste. 
Colour sometimes indicates the taste. White

sweet and sour; black, insipid and poisonous. 
Willdenow. But certainly our spicy wintergreen 
(gaultheria,) partridge-berry (mitchella,) and 
whortleberries (vaccinium,) are exceptions to 
WilldenowV rules. 

Sarmento'se, sarmento'sus. A running shoot, which

Sex'us, Sex. When Linneus first adopted the sta- 
mens and pistils as the organs of classification, he 
addressed his arguments to physicians, who were 
conversant with animal anatomy. He therefore 
took advantage of the analogy between animals 
and vegetables in the reproduction of their kind, 
in order to illustrate his theory. He called the 
stamens males, and the pistils females, &c. But 
nothing can be more ridiculous and disgusting 
than to keep up these references at this day. Dr. 
James Edward Smith, President of the Linnean 
Society at London, has totally discarded all sexual 
allusions. Under the word Clitoria, in Rees' Cy- 
clopedia, he has treated the subject with great se- 
verity. Dr. Bigelow, in his incomparable descrip- 
tion of the plants about Boston, as far as it goes, 
has no where defiled his work with a single allu- 
sion of the kind. 

Sexval'vus. Six-valved.

taining the seeds in extremely minute vertical 
cells. The shields are thick and tumid, when they

Spur'red-ry'e, or spur'red gra'in. An enlarged, 
elongated seed, projecting out of a glume, of a 
black or violet colour, brittle texture, somewhat 
spur-form. It is that morbid swelling of the seed, 
called Ergot by the French. The black or dark 
coloured kind is called the Malignant ergot. 
" Large doses of which cause head-ache and fe- 
brile symptoms. Under proper regulations it may 
be considered a valuable addition to the present 
stock of medicinal agents. The dose usually ad- 
ministered is from ten grains to half a drachm, in 
decoction." Bigelow. The pale violet kind, 
called simple ergot, is harmless and inactive. 

Grain growing in low moist ground, or new 
land is most subject to it. Also spring grain 
more than winter grain ; and rye more than wheat, 
barley or oats. 

When crops are so much infected with it a» 
greatly to injure them, the loss may be in a grea: 
.•neasure made up by collecting the ergot, and sell 

S T E 171 

mg it to druggists. It should be thoroughly win- 
nowed out of the grain, as it is said to be very in- 
jurious in bread. The ergot may then be collect-

stigma, receptacle, calyx or corol. 

Stam'inate. Having stamens only, without a pis- 
til ; consequently barren. As the flowers in the

required in numbering sessile stigmas. No more 
must be numbered, than can be found quite dis- 
tinct on the germ. 

Stings, etim'utu Hair-like processes, which excite 
itching punctures ; as on the Nettle. They arc 
generally hollow with a sack at the base, contain- 
ing an acrid liquor. By pushing against their

Style, stylus. (Stulos, a column.) That part of a 
pistil, which is between the germ and stigma. It 
is often wanting ; as in the Tulip. 

There is frequently a difference in opinion 
among authors in fixing the orders of some plants, 
on account of their numbering the styles differ- 
ently. As in the Mountain rice (Oryzopsis.) 
Richard made it the first order, because the 
two styles seemed to unite a little above the 
germ. But Muhlenberg makes it the second or- 
der, because they are at least separable, if not 
always separate in perfect maturity. It grows in 
abundance about New-Haven, with styles per- 
fectly separate in all stages. From this example 
the student will perceive the importance of look- 
ing through all the orders, where his plant can 
possibly be found, before he determines in diffi- 
cult cases.

ing up.) Anthers growing up together in an unit- 
ed tubular set. The name of the eighteenth class, 
if polyadelphia be rejected, or the nineteenth as 
established by Linneus. It comprises all those 
plants, whose flowers are compound, having the 
anthers in each floret with more or less of their 
edges adnate ; so that the whole (which are always 
5) form a tube. Formerly the union of the an- 
thers was the only circumstance noticed in defin- 
ing this class ; which brought the violet, the car- 
dinal flower, &c. into it. But now the flower be- 
ing compound is taken into consideration ; which 
makes a perfectly natural class, The order mo-

nogamia, which was allotted to the simple tlowers ; 
is of course rejected. The present orders are 
Polygamia cequalis, superjlua, frustranea, necessa- 
ria and segregata; which see. 

Syno'nyms, synon'yma. Different names for the 
same plant. A list of synonyms has now become 
essential to every publication, containing descrip- 
tions of plants ; on account of the vast multipli- 
cation of names. This is ascribable to two 
causes. 1. A Botanist with but little knowledge 
of plants, falls in with a plant which he cannot 
find out ; though it is familiar to practical Bota- 
nists. He immediately gives it a name, and puffs 
himself into the face of the public as the disco- 
verer. 2. Vanity is often a quality of the indo- 
lent. And we find many vain men, who, feeling 
a strong uesire to be cited as the authors of some- 
thing, sit down at home, and split up and new- 
name genera and species ; which they at length 
crowd into books to the great injury of the 

Svnop'sis. A condensed systematic view of a sub- 
ject, or science. 

Sys'tem, syste'ma. An arrangement of natural bo- 
dies according to assumed characters •, for the 
purpose of aiding the mind and memory in ac- 
quiring and retaining a knowledge of them. Sys- 
tems have been proposed in abundance. And we 
are still infested with system-makers and reform- 
ers, which are among the greatest evils incident to 
Natural Science. Any man of ordinary talents 
may make a tolerable system in half a day ; that 
is, sixty systems per month. But why not adhere 
to that which is universally known and establish- 
ed? There may be improvements in the Linnean 
system. But let them be adopted with caution,

pying the end of a stem, branch, style, &c. 

Terminations. In expressing resemblance it 
would greatly lengthen descriptions to introduce 
words drawing full-length comparisons. As a 
leaf resembling the form of an arrow. To avoid 
this, terminations united to the substantive word 
by a hyphen have been used ; as arrow-shape, 
or arrow-form, i prefer the termination form. 
making the whole a compound adjective noun. 
There are cases where like becomes a convenient 
termination ; as petal- like stigma in the Iris. 
Here form or shaped would be inadequate ; as its 
resemblance consists rather in texture and gene- 
ral appearance, than in shape. 

Ter'nate. Three-fold. In threes. This term is 
also applied to compound leaves, where 3 leafets 
proceed from the end of one petiole ; as in the 
Strawberry. See biternate and triternate.

large is very indefinite ; but the distinction be- 
tween tree and shrub is very difficult to express. 
Perhaps large and small, interpreted according to 
the rules relating to parts under Relative propor- 
tions, will serve to distinguish trees and shrubs as 
well as an elaborate definition. These terms are 
not used in specific descriptions. See shrub and

changes respect magnitude, fulness of flowers, 
crisping of leaves, colour, taste and smell. If the 
same kind of plant can possibly be produced from 
the seed of other kinds-, these are but varieties of 
the same species. All apples are but varieties of 
the same species ; because if the seeds of a sour 
apple be planted, they will produce trees bearing 
sour, sweet, tart, red, green, large and small ap- 
ples promiscuously. But the Quince is a differ- 
ent species; because it cannot possibly be pro- 
duced from apple seeds. 

Va'sa, vessels. The sap-vessels of vegetables

Vegetable king'dom. This is the name Lin- 
neus gives to all the subjects of the science ot 
botany. See natural history. 

Vegetable substance. The elementary principles 
of vegetables are principally carbon, hydrogen, 
and oxygen ; some contain nitrogen. 

The proximate principles are very complicated. 
1. Gum is a mucillaginous substance ; as Cherry 
gum, Arabic gum, &c. Most gums are softening 
and sheathing to the stomach, but not very active. 
Professor Silliman found the gum of sassafras 
(laurus sassafras) the most effectual remedy for 
his eyes, after they had been greatly injured by 
the explosion of fulminating silver. 2. Resin, is 
found in most pines. In a more refined and vo- 
latile state it becomes the true balsam ; but the 
substance usually called balsam is a coarse mix- 
ture of resin and volatile oil. Resin and gum 
combined was the substance burned, when/rank- 
' incence offerings were made by the Jews. 3. 
Starch, is the most nutritious part of vegetables. 
The Potatoe consists almost entirely of starch 
crystals. The starch should be washed out of 
flour in making paste ; which can be done best 
after the paste is raised by a little yeast. It 
rhen leaves the gluten almost pure, and very 
strongly adhesive. [Extract from MS. notes ta- 
ken at Professor Silliman's lectures in March, 

Incipient germination seems to increase the 
proportion of gluten and diminish that of the 
starch. For flour made of grain, which had be- 

V I G 187 

gan to sprout in the field during a wet harvest, is 
very adhesive, when manufactured into dough. 

Veil. See calyptra. 

Vtl'lus. Fleecy, or a fleece. This term is also
