Tournefort titled Verbena Lufitanica, latifolia pro- 
tenor. I nit. R. H. 200. Taller broad-leaved Portu- 
o-al Vervain. But I am in fome doubt of its being 
Specifically different from the common fort, though 
the plants in the garden grow much taller than that, 
and the flowers are larger, yet as there is fo near an 
affinity, I cannot be fure they are different. 
The fecond fort grows naturally in molt parts of 
North America ; this fends up many four-cornered 
furrowed {talks from the root, which rile five or fix 
feet high, garniffied with oblong leaves about three 
incheslong, and one broad near the bafe, ending in 
acute points ; they are deeply fawed on their edges, 
and ftand upon (lender foot-ftalks by pairs ; and 
from the fame joints come out ffiort branches, fet 
with fmaller leaves of the fame form. The {talks are 
terminated by fpikes of blue flowers in cl niters, which 
appear in Auguft, and if the autumn proves favoura- 
ble, the feeds will ripen the middle ot October. 
The third fort grows naturally in Spain and Portugal •, 
this is a biennial plant, which periffies foon after the 
feeds are ripe. The {talks rife near two feet high, 
and branch out greatly. The leaves are double wing- 
pointed, and fit dole to the {talks. 1 he flowers are 
difpofed in long loofe fpikes fingly at the end of the 
branches ; they are of a light blue colour, and larger 
than thole of the common fort. It flowers in July and 
Auguft, and the feeds ripen in autumn. 
The fourth fort grows naturally in molt parts of North 
America; this is a biennial plant. The {talks are 
four-cornered, and rife about three feet high. The 
leaves are three inches long, and one broad in the 
middle, ending in acute points ; they are fawed on 
their edges, and are placed by pairs. The (talks are 
terminated by panicles of flowers, which are long, 
(lender, and fuftain fmall white flowers, which are 
ranged loofely •, thefe appear in July, and are fuc- 
ceeded by feeds which ripen in autumn. 
The fifth fort grows naturally in North America; 
this is a biennial plant, whofe bottom leaves are fix 
inches long, deeply jagged on their fides, and fawed 
on their edges ; they are rough, and of a deep green 
colour. The (talks rife two feet high, and are gar- 
niffied at the joints with two fmaller leaves of the fame 
ffiape, placed oppofite. The upper part of the ftalk 
branches out into numerous foot-ftalks, which fuftain 
panicles of fpiked blue flowers ; thefe appear in July 
and Auguft, and if the feafon proves favourable, the 
feeds will ripen in autumn. 
The fixth fort grows naturally at Buenos Ayres ; this 
has four-cornered ftalks which rife to the height of 
five or fix feet, fending out branches by pairs from 
the fide ; they are garniffied with fpear-fhaped leaves 
which are three inches long, and about three quarters 
of an inch broad, whofe bafe embrace the ftalks ; 
they are of a pale green colour, and are fawed on 
their edges. The ftalks are terminated by fpikes of 
blue flowers, which are cluttered together. The longeft 
fpikes are about two inches, the other are about half 
fo long ; thefe appear late in fummer, fo are not of- 
ten fucceeded by good feeds in England. 
The feventh fort grows naturally in Philadelphia. 
The feeds of this were fent me by Dr. Benfel ; this is 
a perennial plant. The lower leaves are heart-ffiaped 
and rough ; they are five inches long, and three and 
a half broad near their bafe, ending in acute points ; 
they are of a dark green colour, and fawed on their 
edges. The ftalks rife fix feet high ; they are four- 
cornered, and branch toward the top, and are termi- 
nated by {lender fpikes of white flowers, formed into 
panicles y thefe appear late in autumn, fo that unlefs 
the feafon proves favourable, the feeds do not ripen 
here. 
The eighth fort grows naturally in Virginia, and alfo 
in Jamaica ; from the latter the late Dr. Hoftoun fent 
me the feeds. The ftalks of this trail upon the 
ground, and emit roots from their joints, whereby 
they fpread, and propagate greatly ; and from thefe 
arife other branches about eight or nine inches high, 
which are garniffied with oval fpear-fhaped leaves, 
V E R 
placed oppofite ; thefe are about an inch long, and 
half an inch broad, fawed on their edges, and fit clofe 
to the ftalks. The flowers are co! letted iri' conical 
heads, {landing upon long naked foot-ftalks which 
fpring from the wings of the branches • they are of a 
yellowiffi white colour, and come late in autumn, fo 
are rarely fucceeded by good feeds here. 
Tne ninth fort grows naturally in moft of the iflands 
in the Weft-Indies ; this is an annual plant. The 
ftalk rifes a foot and a half high, and is garniffied with 
oblong oval leaves placed by pairs ; they are of a 
light green colour, and are fawed on their edges. The 
ftalk is terminated by a long fleffiy fpike of blue 
flowers which appear in July, and are fucceeded by 
two oblong feeds which ripen late in autumn. The 
fpikes of flowers are from a foot to a foot and a half 
in length, ' 
The feeds of the tenth fort were fent me from Pana- 
ma, where it grows naturally in moift places ; this is 
an annual plant, whofe ftalks rife about a foot high, 
and are garniffied with oval, blunt-pointed, flelhy 
leaves, {landing upon long foot-ftalks ; and at the 
fame joints come out other ftalks, fuftaining three or 
four {mail leaves of the fame ffiape ; they are notched 
{lightly on their edges, and are of a light green co- 
lour. The ftalks are terminated by thick fleffiy fpikes 
of blue flowers, which appear late in autumn, fo that 
unlels the feafon proves warm, the feeds do not ripen 
in England. 
The feeds of the eleventh fort were fent me from Pa- 
nama, by the late Mr. Robert Millar ; this riles with 
a ffirubby ftalk near three feet high, which divides 
into three or four branches ; thefe are garniffied With, 
oblong oval leaves placed by pairs, which are deeply 
fawed on their edges ; they are of a deep green on 
their upper fide, but are hoary on their under ; their 
foot-ftalks are ffiort, and have leafy borders running 
from the bafe of the leaves. The flowers grow on 
thick fpikes, which terminate the branches, and are 
about a foot long. The flowers are large, and of a 
fine blue colour, fo make a fine appearance, and have 
fmall acute-pointed leaves intermixed with them on 
the fpikes. This plant flowers in Auguft, and when 
the feafon proves warm, the feeds ripen in autumn. 
The feeds of the twelfth fort were fent me from Pa- 
ris, and were faid to come from Senegal in Africa ; 
this is a perennial plant, with a branching ftalk which 
rifes near two feet high, and is garnifhed with oval 
fawed leaves placed by pairs, which are two inches 
and a half long, and almoft two inches broad, of a 
deep green on their upper fide, but hoary on their un- 
der, and have pretty long foot-ftalks. The flowers 
are difpofed in fiefhy fpikes at the end of the 
branches ; thefe fpikes are ffiorter, and not fo thick 
as thofe of the former forts. The flowers are fmall 
and white, fo make no great appearance ; they appear 
in June and July, and the feeds ripen in autumn, but 
the plants may be preferved two or three years in a 
warm ftove. 
The thirteenth fort grows naturally in Jamaica, and 
feveral other places in the Weft-Indies. The feeds 
of this were fent me from La Vera Cruz by the late 
Dr. Houftoun ; this rifes with a ffirubby branching 
ftalk five or fix feet high. The branches are adorned, 
with fpear-fhaped leaves, which are two inches long, 
and half an inch broad ; thefe are fawed on their 
edges, the teeth of the jags coming from the point 
of a fold or plait in the leaf; theie ftand by pairs 
upon fhort foot-ftalks. The flovvei s ftand upon long 
naked foot-ftalks, which rife from the wings of the 
ftalk ; they are blue, and are collected in oval heads ; 
thefe appear late in autumn, and unlefs the feafon 
proves warm, the feeds do rarely ripen in England, 
but the plants may be kept two or three years in a 
warm ftove. 
The fourteenth fort was found growing naturally at 
Campeachy by the late Dr. Houftoun, who fent the 
feeds to England ; this has a fhrubby branching ftalk, 
which rifes three or four feet high. The branches are 
garniffied with oval fawed leaves fet on by pairs j they 
are-
