trees, and rife to a great height ; the leaves are fmooth, 
heart-fhaped, ending in long points, and the ears at 
the bafe are large and rounded, Handing upon 
long ilender foot-ftalks. The flowers come out on 
the oppofite fide of the ftalks, upon long foot-ftalks, 
each fuftaining three flowers, with longer tubes' than 
thofe of the former, and are of a deeper purple co- 
lour ; this flowers from the latter end cf June till 
the froft deftroys it. As this is not fo hardy as the 
former, the feeds fhould be fown upon a hot-bed in the 
fpring, to bring the plants forward ; and toward the end 
of May, they fhould be planted out in warm borders, 
and treated in the fame manner as the former fort. 
The fixth fort grows naturally in Africa and America •, 
this is. an annual plant, which rifes with a twining 
ftalk eight or ten feet high, garnifhed with heart- 
fhaped leaves, divided into three lobes, which end 
in ftiarp points ; thefe are woolly, and ftand upon 
long foot-ftalks ; the flowers come out on long foot- 
ftalks, each fuftaining two flowers of a very deep 
blue colour, from whence it has been titled Anil or 
Indigo. This is one of the molt beautiful flowers of 
this genus, and is undoubtedly a diftinft fpecies •, 
though fome have fuppofed it to be only a variety of 
the fourth fort, for I have cultivated it many years, 
and have never found it alter •, the leaves of this hav- 
ing three deeply divided lobes, and thofe of the fourth 
fort being entire, is fufficient to determine the ipeci- 
fic difference ; this fort is annual, and muft be pro- 
pagated. in the fame manner as the fifth. It flowers 
all the latter part of fummer, and, in good feafons, 
the feeds ripen well in the open air. 
The feventh fort is that whofe roots are eaten, and 
is generally titled Spanifli Potatoe ; thefe roots are an- 
nually imported from Spain and Portugal, where 
they are greatly cultivated for the table, but they 
are too tender to thrive well in the open air in Eng- 
land ; they are cultivated by the roots in the fame 
way as the common Potatoe, but require much more 
room; for thefe fend out many trailing ftalks, which 
extend four or five feet every way, and at their joints 
fend out roots, which, in warm countries, grow to 
be large tubers, fo that from a ftngle root planted, 
forty or fifty large roots are produced. This plant 
is fometimes propagated by way of curiofity in Eng- 
land, but the roots fhould be planted on a hot-bed 
in the fpring ; and if the plants are kept covered in 
bad weather with glaffes, they will produce flowers, 
and many fmall roots will be produced from the 
joints ; but if they are expofed to the open air, they 
leldom make much progrefs. 
The eighth fort grows naturally at La Vera Cruz in 
New Spain, from whence the feeds were lent me by 
the late Dr. Houftoun. This rifes withaftrong wind- 
ing ftalk to the height of tv/enty feet, dividing into 
feveral fmaller, which fallen themlelves about any of 
the neighbouring trees and fhrubs ; thefe are gar- 
nifhed with leaves in fhape of a hand, having feven 
lobes, which are fpear-fhaped, and deeply cut on 
their borders, ending in fharp points. The flowers 
are Angle on each foot-ftalk, which are very long. 
The empalement of the flower is large, fpreading 
open, and is divided deeply into five parts. The 
flowers are large, of a purple colour, and are Suc- 
ceeded by large roundifh feed-vefiels, having three 
cells; in each of thefe is lodged a Angle feed. 
This plant ic tender, fo the feeds fhould be fown on 
a hot-bed in the Spring ; and when the plants are fit 
to remove, they mull be tranfplanted each into a le- 
parate pot filled with light earth, and plunged into a 
moderate hot-bed, obferving to fikade them from the 
fun till they have taken new root ; then they fhould 
have a large Ihare of air admitted to them everyday, 
to prevent their drawing weak, and alxb fhould have 
moderate waterings three or four times a week. 
"When the plants are grown too tall to remain in the 
hot-bed, they muft be Shifted into larger pots, and 
placed in the bark-ftove, where, if they are allowed 
room, they will rife to a great height, and produce 
flowers, but it rarely produces feeds in England. 
The ninth fort is an annual plant. The feeds of this 
were fent me from Carthagena in New Spain, where 
the plant grows naturally. This rifes v/itli a twining 
ilender ftalk ten feet high, which is garnifhed- with 
arrow-pointed leaves, whofe ears at The bale are 
rounded. The flowers are produced in fmall duffers# 
Handing on long foot-ftalks ; thefe are yellow, and 
are Succeeded by three-cornered feed-veffels, having 
three cells, in each of thefe are lodged two feeds. 
This plant is annual, and too tender to thrive in the 
open air in England ; fo the feeds fhould be fown on 
a hot-bed in the fpring, and the plants may be after- 
ward treated in the fame way as the eighth fort, with 
which management they will flower and produce ripe 
feeds. 4 
The feeds of the tenth fort were fent me from Ja- 
maica by the late Dr. Houftoun, who found the plants 
growing naturally there in great plenty. This is an 
annual plant, rifing with Ilender, ftiff, twining ftalks, 
eight or nine feet high, garnifhed with heartfthaped 
leaves, which are downy. The flowers ftand many 
together at the end of ftrong foot-ftalks ; thefe are 
. purple, and are fucceeded by roundifh feed-veffels, 
with three cells, containing feveral fmall feeds. 
This fort requires the fame treatment as the eighth, 
being too tender to thrive' in this country in the "open 
air. 
The eleventh fort was fent me from the ifland of 
Barbuda. This is an annual plant, which riles with 
twining ftalks feven or eight feet high, garnifhed 
with oblong, oval, fmooth leaves. The flowers 
come out at every joint on Ilender long foot-ftalks, 
each fupporting a large purple flower, whofe empale- 
ment is cut alrnoft to the bottom, in ten parts. "The 
feeds and capfuie are like thofe of the other fpecies. 
This is a tender plant, fo muft be treated in the fame 
manner as the eighth fort. 
The twelfth fort grows naturally at Carthagena in 
New Spain, from whence I received the feeds. This 
is a perennial plant, which rifes with ftrong winding 
ftalks to the height of twelve or fourteen feet, and 
are garnifhed with leaves, divided into five lobes. 
Handing upon fhort foot-ftalks ; the flowers ftand 
upon long foct-ftaiks, each fuftaining two purple 
flowers. The ftalks, leaves, and every part of the 
plant, is clofely covered with pungent fringing hairs, 
of a light brown colour. This fort is tender, fo muft 
be treated in the fame way as the eighth. 
The thirteenth fort grows naturally about Tolu in 
New Spain, from whence the feeds were fent me by 
the late Mr. Robert Millar. This hath a ligneous 
ftalk covered with a purple bark, which twines" about 
the trees, and rifes to the height of thirty feet or 
more, and is garnifhed with leaves, which are deeply 
divided into five fnarp-pointed lobes. The flowers 
ftand upon long thick foot-ftalks, which have a knee 
in the middle ; they are very large, and of a purple 
colour ; thefe are fucceeded by round feed-veffels, as 
large as a middling Apple, divided into three cells, 
each containing two very large fmooth feeds. 
This plant is too tender to thrive in the open air in 
England, fo muft be treated in the fame manner as 
the eighth fort, but it grows too tall for the ftoves 
here. I have had thefe plants upward of twenty feet 
high, which have fent out many fide branches, ex- 
tending fo wide on every fide, as to cover moft of 
the neighbouring plants, fo that I was obliged to re- 
move them into a cooler fituation, where they would 
not thrive. 
The fourteenth fort grows naturally on the fea fhdres 
in moft of the iflands in the Weft-Indies, where the 
ftalks trail on the ground, which are garnifhed with 
oval leaves, indented at the top. The flowers are 
large, of a purple colour, and are produced by threes, 
on very long foot-ftalks ; thefe are fucceeded by large 
oval feed-veffels, with three cells, each containing a 
Angle feed. This hath a perennial ftalk, which trails 
on the ground, and fpreads to a great diftance, but 
is too tender to thrive in the open air in England, fo 
muft be treated in the fame manner as the eighth fort,
