The fifth fort grows naturally in Crete. The root of 
this is perennial, and fends out many trailing branches, 
which extend one foot and a half in length, garnifhed 
with oblong heart-fhaped leaves, which are waved 
on their edges, and are evergreen. The flowers come 
out fingly from the wings of the leaves, which are 
of a dark purple colour, in fnape like the others, but 
the plants never produce feeds in England, fo is pro- 
pagated by parting of the roots : this is too tender to 
thrive in the open air in winter ; the plants are pre- 
ferved in pots, and placed under a common frame in 
winter, where they fhould have as much free air as 
pofiible in mild weather, but fcreened from hard froft; 
in mild winters I have had this plant live abroad in a 
warm border, but in hard winters it will be deftroyed; 
therefore one or two plants fhould be fheltered to 
preferve the fpecies. 
The fixth fort is the Snakeroot, which is greatly ufed 
in medicine : thefe roots are brought from Virginia 
and Carolina, where there are two fpecies of this 
plant, but this fort is the bed: for ufe. There are 
fome of thefe preferved in the gardens of thofe who 
are curious in colle&ing rare plants, but as they are 
fometimes killed by froft in winter, fo they are not 
very common in the Englifh gardens. This is pro- 
pagated by feeds, which fliould be fown in the au- 
tumn, in fmall pots filled with light fandy earth, and 
placed under a common frame in winter, and after- 
ward treated in the fame manner as hath been di- 
rected for the two firft forts, as fliould the plants alfo; 
with which management they will produce their flow- 
ers, and perfeft their feeds every year. 
The feventn fort grows naturally in North America, 
and is by fome called Snakeroot, but is not near fo 
ftrong as the former ; the branches of this grow ereCt, 
and are perennial, whereas thofe of the other fort de- 
cay to the root every winter : this rifes about two 
feet high •, the branches are not very woody, but are 
ftrong enough to fupport themfelves the leaves are 
oblong and heart-fhaped ; the flowers come out fingly 
at the wings of the leaves. This will live abroad in 
warm borders, with a little protection in hard frofts. 
It is generally kept in pots, and flickered in winter ; 
but thofe which are planted in the full ground will 
thrive much better, provided they are fcreened from 
hard frofts. 
The eighth fort grows naturally in Jamaica, where it 
is called Contrayerva •, the roots are there ufed as fuch : 
this hath long trailing branches, which climb upon 
the neighbouring plants, and rife to a confiderable 
height •, the leaves are placed alternately, and are of 
the long heart-fhaped kind ; the flowers are produced 
in fmall clufters toward the upper part of the ftalks, 
which are of a dark purple colour ; the feed-veflels 
are oblong and fniooth. This is tender, and, in win- 
ter fliould have very little wet, therefore mull be con- 
ftantly kept in the ftove, ctherwife it will not live in 
England. 
The ninth fort was difcovered by Dr. Tournefort in 
the Levant. This hath fome refemblance to the fe- 
cond fort, but the leaves are hairy, and not fo deeply 
eared at the bottom •, the flowers are alfo much larger. 
This may be propagated by feeds, in the fame man- 
ner as hath been directed for the firft and fecond 
forts, and the plants treated fo, will thrive very well 
in England. 
The tenth fort fends out climbing ftalks, which fup- 
port themfelves by fattening to the neighbouring 
trees, and thereby rife to a very great height •, the 
leaves are very broad and heart-fhaped, having feve- 
ral longitudinal veins ; the flowers grow in loofe 
bunches at the extremity of the branches, each hav- 
ing a long foot-ftalk : this is tender, fo muft be kept 
in a ftove, and treated as other exotic plants. It 
grows naturally about Tolu in New Spain, where it 
was difcovered by the late Mr. Robert Millar, who 
fent the feeds to England. 
The eleventh fort was difcovered by the fame gen- 
tleman atCampeachy in New Spain, from whence he 
fent the feeds.: this fort ieldom climbs above three 
of four feet high ; the. leaves are Chart and heart-fhap- 
ed, in fome meafure like thofe of the firft •, the flow- 
ers corne out in fmall clufters from the wings of the 
leaves, and are of a dark purple colour; 
The twelfth fort was difcovered at La Vera Cruz in 
New Spain, by the late Dr. Houfton, who fent the 
feeds to Europe : this rifes with an upright ftalk, to 
the height of three feet * the leaves are long, nar- 
row, hairy, and grow clofe to the branches, having 
fcarce any foot-ftalk ■, the flowers come out fingly 
from the wings of the leaves, which are near four 
inches long, of a dark purple colour, and grow erect ; 
thefe are fucceeded by flender veffels, about one inch 
long, which open into fix cells, filled with flat heart- 
fhaped feeds. This fort requires a warm ftove to 
preferve it in this country. 
The thirteenth fort was difcovered by Mr. Robert 
Millar, near Carthagena in New Spain, who fent it to 
England ; this hath ftrong climbing ftalks, by which 
it mounts up to the top of the tailed: trees ; the leaves 
of this are four inches long and two broad, of an oval 
fnape, rounded at their ends, and are nearly as thick 
as thofe of the common Laurel •, the flowers come 
out in loofe clufters at the ends of the flioots, each 
Handing on a very long foot-ftalk ; the feed-veflels 
are four inches long, and as much in circumference, 
having fix longitudinal ribs, which make fo many an- 
gles, being very prominent •, they open into fix cells, 
which are filled with heart-fhaped leaves. 
All thefe forts, which are natives of the warm parts 
of America, are too tender to thrive in the open air in 
this country, therefore require a ftove to preferve 
them. They are propagated by feeds, which muft be 
procured from the countries where the grow naturally, 
for they do not produce any here. As the feeds are 
a confiderable time in their paflage, they fhould be 
brought over in their pods ; for many of the forts have 
very thin light feeds, which are foon dried in a hot 
country, when they are out of their covers, which 
will prevent their growing. So foon as the feeds ar- 
rive, they fliould be fown in fmall pots filled with 
light earth ; and if this happens in the autumn, or 
winter, the pots fliould be plunged into the tan in 
the bark-ftove, between fome of the pots with large 
plants, which will fcreen them from the fun ; for as 
thefe plants delight in fhade, fo, by thus placing of 
the pots, the earth will not dry very faft, which will 
be of great advantage to the feeds, which fhould not 
be too often watered. Here the pots may remain till 
March, at which time they fliould be removed, and 
plunged into a hot-bed, under frames, where, if the 
feeds are good, the plants will appear in May : but 
if the feeds arrive in fpring or fummer, they muft be 
immediately fown in fmall pots, and plunged into a 
moderate hot-bed, obferving to fhade them conftantly 
in the heat of the day ; but the feeds fown at this fea- 
fon feldom grow the fame year ; therefore if the plants 
do not appear, the pots fliould be plunged in the tan- 
bed of the ftove in autumn, and in the fpring follow- 
ing, treated as before directed, which will bring up 
the plants. When thefe are ftrong enough to trani- 
plant, they fhould be each put into a feparate fmall 
pot, and plunged into the tan-bed in the ftove, and 
treated as other tender plants from the fame coun- 
tries. 
ARMENIACA, the Apricot. 
The Characters are, 
The empalement of the flower is bell-Jhaped , cut into five 
blunt fegments at the top ; the flower is compofed of five 
large roundiflo petals which flpread open , whofle bafle are 
inferted in the empalenient ; in the center is placed a round 
germen , fupporting a flender fiyle , crowned by a round 
fiigma \ this is attended by upward of twenty awl-Jhaped 
ftamina , which are crowned by floor t double jummits. The 
germen afterward becomes a roundiflo pulpy fruity having 
a longitudinal furrow incloflng a roundiflo nut , which is a 
little comprefl'ed on the fides. 
Dr. Linnaeus has joined the Armeniaca, Cerafus, Lau- 
rocerafus, and Padus, to his genus of Prunus, making 
them only fo ..many fpecies, of the fame genus, and
