like thofe of this fort, fo that I doubt whether it 
be a diftindt fpecies. 
The fifth fort grows naturally in New England and 
Virginia, from both of thefe counties I have received 
the feeds ; this hath a perennial root and an annual 
{talk ; it rifes with upright ftalks about a foot high •, 
thefe have their joints pretty near each other, where 
they are garnifhed with roundifh heart-fnaped leaves, 
fitting clofe to the ftalks ; they are fawed on their 
edg s, and are of a light green colour. The flowers 
are produced in fmall loofe panicles at the top of 
the ftalks * they are white, and have two fmall green 
leaves immediately under the flowers. Thefe flowers 
appear the latter end of June, but the feeds feldom 
ripen in England. 
The fixth fort grows naturally at La Vera Cruz in 
America, from whence the late Dr. Houfton fent me 
the feeds •, this hath a fhrubby climbing ftalk, which 
rifes to the height of ten or twelve feet, fattening itfelf 
to any neighbouring prop for fupport, and is gar- 
nifhed with heart-fhaped leaves, placed oppofite ; 
they are about three inches long, and one and a half 
broad, of a lucid green •, the flowers come out in long 
branching panicles, which proceed from the fide of 
the ftalks, and are terminated by a branching pani- 
cle of white flowers. This fort is tender. To will 
not live in this country without artificial heat. 
The feventh fort rifes with upright ftalks three feet 
high, garnifhed with oval leaves at each joint, which 
are placed oppofite •, they have very fliort foot- 
ftalks, and are fawed on their edges ; from the fides 
of the ftalks, at every joint, is produced two {lender 
branches, which ftand ered ; thefe, and the principal 
ftalks alfo, are terminated by clufters of white 
flowers •, they appear in Auguft and September, and 
the ftalks decay in winter, but the root is perennial. 
This grows naturally in Penfylvania, and other parts 
of America. 
The eighth fort grows naturally in Virginia and Phi- 
ladelphia ; this hath a perennial root and an annual 
ftalk, The ftalks rife from two to three feet high ; 
they are hairy, and garnifhed with rough leaves at each 
joint, which are from three to four inches long, and 
about an inch broad at their bafe, gradually ieffening 
to a very acute point ; the two leaves are joined at 
their bafe, fo the ftalks feem to grow through them •, 
they are of a dark green, and are covered with fliort 
hairs. The upper part of the ftalk divides into many 
flender foot-ftalks, each fuftaining a clofe clutter of 
white flowers. Thefe come out in July, and in warm 
feafons the feeds will fometimes ripen in England. 
The ninth fort grows naturally at La Vera Cruz, from 
whence the late Dr. Houftoun fent me the feeds ; this 
rifes with an upright ftalk near two feet high, gar- 
nifhed toward the bottom with oblong obtufe leaves, 
which are of a thick fubftance, and crenated on their 
edges ; the upper part of the ftalk is naked to the 
top, where the flowers come out in a thick panicle ; 
they are blue, and have Angle empalements. This 
flowers late in autumn, but never ripens ieeds here; the 
root is biennial, and perifhes fcon after it has flowered. 
The tenth fort was fent me by the late Dr. Houftoun 
from La Vera Cruz, where he found it growing na- 
turally this hath a thick woody ftalk, which rifes 
twelve or fourteen feethigh, fending out many branches, 
which are channelled, and covered with a brown 
bark, garnifhed with regular heart-fhaped leaves 
as large as thofe of the Mulberry-tree; they are 
of a light green colour, and fawed on their edges, 
placed oppofite upon foot-ftalks, near two inches 
long ; the upper part of the branches are terminated 
by four or five pair of foot-ftalks, which come out 
oppofite from the joints, and the top is terminated by 
an odd one ; thefe fuftain branching panicles of white 
flowers, which together form a long loofe pyramidal 
thyrfe, and make a fine appearance, for there are no 
leaves intermixed with the flowers, but fo far as the 
fpike reaches the ftalks are naked. This fort has 
flowered in the Chelfea garden, but did nor produce 
feeds. 
The eleventh fort grows naturally at La Vera Cruz, 
from whence the late Dr. Houftoun fent it me ; this 
rifes with many fhrubby ftalks near five feet high, 
which divide into many flender branches, whole joints 
are three or four inches afunder ; at each of thefe come 
out two oval leaves about three quarters of an inch 
long, and half an inch broad, ftanding upon long 
flender foot-ftalks , they have feveral black fpots on 
their iurface. The branches come out horizontal, and- 
are terminated by fmall bunches of white flowers, 
! whofe empalements are Angle, and compofed of fe- 
ven narrow fpear-fhaped leaves, which are divided to 
the bottom. 
The twelfth fort rifes with an upright round ftalk to 
the height of three feet, fending out feveral branches 
toward the top, which come out regularly by pairs ; 
they are garnifhed with leaves, placed by pairs ; 
j thefe are two inches and a half long, and about 
one third of an inch broad, having three longitudinal 
veins ; they are of a light green colour, and entire. 
The flowers ftand upon long foot-ftalks at the end of 
the branches, fome fuftaining one, fome two, and 
others three or four flowers ; they are white, and ap- 
pear late in autumn. This grows naturally in Carolina. 
The thirteenth fort grows naturally in Maryland ; this 
hath a perennial root and an annual ftalk, which rifes 
three feet high, dividing upward into many branches, 
which are cloiely garmlhed with narrow fpear-fhaped 
leaves, which are from two to three inches long, and 
a quarter of an inch broad, of a deep green, fitting 
clofe to the branches ; they have three longitudinal 
veins, and their upper part fharpiy fawed on their edges, 
ending in acute points. The branches are termi- 
nated by roundifh clufters of white flowers, which 
appear in Auguft, and continue till Qdtober ; and 
in warm feafons they are fucceeded by feeds, which 
ripen here. 
The fourteenth fort grows naturally in Jamaica, and 
in moft of the other Hands in the Weft-Indies; this 
rifes with fhrubby ftalks about fix or feven feet high, 
dividing into many branches, which are garnifhed 
with heart-fhaped leaves, ending in acute points, in- 
dented on their edges, having three longitudinal veins; 
the upper part of the branches are terminated by {len- 
der foot-ftalks, each fuftaining a fmall clufter of white 
flowers, included in oblong fcaly empalements of ^ 
filvery colour. 
The fifteenth fort was fent me from La Vera Cruz 
by the late Dr. Houftoun ; this riles with an upright 
branching ftalk three feet high, fending out two fide 
branches from every joint, almoft the whole length, 
which are terminated by loofe fpikes of red flowers, 
as is alfo the principal ftalk. The leaves are heart- 
fhaped, rough, and are crenated on their edges, fitting 
clofe to the ftalks ; they are of a light green, and a 
little hoary. 
The fixteenth fort was fent me from Jamaica by the 
late Dr. Houftoun ; this hath flender twining ftalks, 
which faften themfelves to any neighbouring Tupport, 
and rife eight or ten feet- high, fending out fmall 
branches oppofite, at moft of the upper joints. The 
leaves on the lower part of the ftalk are heart-fhaped, 
ending in acute points ; the upper leaves are almoft 
triangular, they are ftnooth, and of a lucid green ; 
the upper part of the ftalks have long branching fpikes 
of white flowers, which are fmall, and fit clofe to the 
foot-ftalks. 
The feventeenth fort grows naturally in Penfylvania ^ 
this hath a perennial root, from which arife feveral 
upright ftalks, which grow to the height of feven or 
eight feet, in a moift foil, or where they are fupplied 
with water in dry weather, and are garnifhed with 
oval, rough, fpear-fhaped leaves, which are a little 
fawed on their edges ; they are placed in whorls round 
the ftalks, lbmetimes feven, at other places four or 
five of thefe ftand at each joint ; they are about three 
inches long, and two inches broad. The ftalks are 
terminated by a loofe corymbus of purple flowers, 
which appear in Auguft and continue till Qdlober, 
but are not fucceeded by feeds in England.
