The hr.lt fort grows naturally In Cappadocia, &c. near 
the fea fhore ; this rifes about two feet and a half high, 
fending out branches, garnifhed with leaves divided 
into many parts, and upon being handled emit a ftrong 
odour. The fpikes of flowers are produced from the 
•wings of the Italics, which are long, Angle, and hairy; 
the upper part being furnilhed with many male flow- 
ers, and the lower part with female flowers ; thefe 
grow dole to the ftaik. After the flowers are pail, 
the female flowers are fucceeded by hard leafy cap- 
fules having one cell, in which is included a Angle 
round feed. This is an annual plant, which leldom 
' perfects its feeds in England, unlefs the plants are 
brought forward in the fpring ; therefore the feeds 
ihouid be Town in the autumn in a warm border, and 
when the plants come up in the fpring, they fliould 
be tranfplanted into another warm border of poor 
ground •, for wdien theie plants are put into rich moift 
land, they grow very luxuriantly, fo do not flower 
till late in the feafon. Therefore the befr method to 
obtain good feeds, is to plant feme of the plants in 
lime rubbiih, to prevent their luxuriant growth, which 
will caufe them to flower early, whereby good feeds 
may be obtained. 
It the feeds ripen and are permitted to fcatter, the 
plants will come up the following fpring without care-, 
for when the feeds are fown in the fpring, the plants 
feldom come up the fame year, but will remain in the 
ground a year before they vegetate. There is not 
much beauty in this plant, fo it is not often admitted 
to have a place in gardens, except in thofe where a 
variety of plants are preferved. 
The fecond fort grows naturally in the iflands of 
America, as alfo in Carolina and Virginia from the 
two latter countries I have frequently received the 
feeds, and in the tubs of earth which came with plants 
from the former, the plants have come up in plenty, 
fo is undoubtedly a common weed there. This grows 
more than three feet high, dividing into many branches; 
garnifhed with winged leaves in fhape like thofe 
* of Mugwort ; at the extremity of each branch, the 
loofe fpikes of flowers are produced, compofed of one 
long fpike in the middle, and three or four fhorter 
lateral fpikes : thefe are fmooth, and have male and 
female flowers ranged in the fame manner as the 
former ; the female flowers are fucceeded by feeds of 
the fanle lhape. 
This fort will come up and thrive in the open air in 
England, but the plants fo raifed v/ill not produce 
good feeds, unlefs the feafon is warm ; therefore fo 
obtain them every year, it is neceffary to cultivate 
them in the following manner. 
The feeds of this plant fliould be fown on a moderate 
hot-bed in March, and when the plants are come up 
two inches high, they muft be tranfplanted into ano- 
ther moderate hot-bed, allowing each plant three or 
four inches fquare ; obferving to water them pretty 
well, and fnade them until they have taken new root; 
afterward they muft have a large fhare of frefli air 
every day, when the weather is warm, and frequent 
.waterings, for they are very thirfty plants. When the 
plants are grown pretty ftrong, they muft be taken 
up with balls of earth to their roots, and planted in 
large pots filled with light earth ; and if they are 
placed on a very moderate hot-bed until they are -well 
rooted, it will greatly forward their flowering. Toward 
the latter end of May they fliould be placed abroad 
A M E 
with other hardy annual plants, among which they 
will make a variety. Thefe will flower In July, and 
their feeds ripen in September. 
The third fort is a native of North America, where 
it is a very common weed. This often grows eight 
or ten feet high ; and if it is planted in a rich moift 
foil, or is often watered, It will grow much higher, 
and fpread out into many branches. The feeds of 
this plant, when fown in the fpring, feldom come up 
the firft year, but frequently remain in the ground 
until the following fpring ; lb that when the plants do 
not come up, the ground muft not be difturbed till 
after the fpring following. When the plants come 
up, fome of them may be tranfplanted into a moift 
rich foil, allowing them at lea ft four or five feet room 
every way ; If they are frequently watered in dry 
weather, they will grow to a large fize ; but their 
branches muft be fupported by flakes, otherwlfe they 
are very fubjeft to break with ftrong winds. The 
flowers of this plant are not more confpicuous than 
thofe of the Hemp, to which thefe are near akin ; 
therefore are only preferved. by fuch perfons as are 
curious in botany, for the fake of variety. If the 
feeds of this fort ripen and are buffered to fcatter, the 
plants v/ill come up the following fpring, provided 
the ground is not difturbed ; or if the feeds are fown 
in autumn, the plants will come up the following 
fpring, and may be treated as above. 
The fourth fort grows naturally In North America, 
from whence I have frequently received the feeds. 
This divides into many branches, the lower part of 
which are garnifhed with whole leaves, but the upper 
part hath compound leaves refembling thofe of the 
fecond fort ; the fpikes of flowers are produced from 
the wings of the ftalks, in which this differs from the 
fecond. This may be treated in the fame manner as 
the fecond fort. 
The fifth fort is a native of Peru, from whence the 
younger Juflieu fent the feeds to the royal garden at 
Paris, and by the generofity of his brother Dr. Bar- 
nard de Juffieu, I was favoured with this plant, which 
has fucceeded in the Chelfea garden, where it annually 
perfe£ts its feeds. 
This grows to the height of ten or twelve feet, with 
a woody Item, dividing into feveral branches, gar- 
nifhed with hairy leaves, compofed of feveral winged 
lobes, and are placed alternately upon the branches ; 
the fpikes of flowers are Angle, hairy, and are pro- 
duced at the extremity of the branches. The female 
flowers (which are fituated below the male, on the 
fame fpikes) grow in fmall duffers, at feparate dif- 
tances, each having two long narrow fegments of the 
empalement, which rife above the capflile or feed 
veffel. 
This is a perennial plant, and may be propagated by 
cuttings or feeds ; it’ by the former, they fhould be 
planted in a ftiady border, in either of the ftimmer 
months ; thefe will require to be frequently watered : 
in a month or five, weeks they will have good roots, 
therefore fhould then be taken up and potted ; for 
when they are left longer in the full ground, they 
will grow very luxuriant, and not fo foon recover 
their removal, as thofe which are tranfplanted earlier, 
Thefe plants are hardy, fo may be expofed to the 
open air in furnmer ; and in the winter, If they are 
flickered in a common green-houfe, with Myrtles and 
other hardy exotic plants, they will live feveral years. 
In mild winters, the roots of this plant have lived in 
the full ground in a warm border, without any co- 
vering, but hard froft will kill them. 
The feeds of this fort feldom come up the fame year, 
when they are fown in fpring, but thofe which have 
fallen in the autumn, have grown the following year, 
and fo have thofe which have been fown at the fame 
feafon.
