The true Jalap. 
The firft fort is very common upon dry banks, and 
in gravelly grounds, in moft parts of England, and 
is generally a flgn of gravel lying under the fur- 
face. The roots of this fhoot very deep into the 
ground, from whence fome country people call it 
Devils Guts. 
From the root arifes many weak ftalks, which trail 
CON 
on the ground, and faften themfelves about the neigh- 
bouring plants 5 tfiefe are garnifhed with triangular 
arrow-pointed leaves. The flowers are produced 
from the fide of the branches, having long foot- 
ftalks, each fuftaining a Angle flower, which is fame- 
times white, at other times red, and frequently is va- 
riegated. This is atroublefome weed in gardens* fo 
fhould be conftantly -rooted out. 
The fecond fort is alfo a troublefome weed in gar- 
dens, when the roots are intermixed with thofe of 
trees and fhrubs, or under hedges, where the plants 
cannot be t eafily deftroyed ; but in an open dear fpot 
of ground, where the plants are carefully hoed down 
for three or four months, they may be effectually de- 
ftroyed •, for when the ftalks are broken or cut, a 
milky juice flows out, and thereby the roots are foon 
exhaufted and decay. The roots of this fort are pretty 
thick, extend far on every fide, and are white. The 
ftalks rife ten or twelve feet high, twining themfelves 
about trees or hedges, and are garnifhed with large 
arrow-pointed leaves, which are torn at their bale. 
The flowers come out from the fide of the branches 
upon long foot-ftalks, each fuftaining one large white 
flower, which are fucceeded by roundifh leed-veflels, 
Laving three cells filled with feeds, which are convex 
on one fide and plain on the other. It flowers in 
June, and the feeds ripen in autumn, loon after 
which the ftalks decay to the root •, but as every fmall 
piece of the root will grow, it renders this a trouble- 
fome weed to deftroy. 
The third fort grows naturally in Syria, where the 
roots of the plants are wounded, and fhells placed 
under the wounds to receive the milky juice which 
flows out, which is infpiffated, and afterward put up 
and exported : this is what is called Scammony in the 
fhops j it is a very hardy plant, and will thrive very 
well in the open air in England, provided it is on a 
dry foil. The roots of this are thick, run deep into 
the ground, and are covered with a dark bark. The 
branches extend themfelves on every fide to the dif- 
tance of four or five feet ; thefe are {lender, and trail 
on the ground, if they are not fupported, and are 
garnifhed with narrow arrow-pointed leaves. The 
flowers are of a pale yellow, and come out from the 
fide of the branches, two fitting upon each long foot- 
ftalk ; thefe are fucceeded by roundifh feed-veffels, 
having three cells, filled with feeds fhaped like thofe 
of the former fort, but fmaller. It flowers in June 
and July, and the feeds ripen in autumn. If the 
feeds of this fort are fown in the fpring, on a border 
of light earth, the plants will come up, and require 
no other culture but to keep them clean from weeds, 
and thin the plants where they grow too clofe; for 
as the branches extend pretty far, the plants fhould 
not be nearer than three feet afunder. The ftalks 
decay in autumn, but the roots will abide many 
years. 
The fourth fort is an annual plant, which grows 
naturally in Afia and America, but has been long 
cultivated for ornament in the Englifh gardens, and 
is generally known by the title of Convolvulus major. 
Of this there are three or four lafting varieties the 
moft common hath a purple flower • but there is one 
with a white, another with a red, and one with a 
whitifh blue flower, which hath white feeds. All 
thefe varieties I have cultivated many years, without 
oblerving either of them change. If the feeds of 
thefe forts are fown in the fpring, upon a warm bor- 
der where the plants are defigned to remain, they will 
require no other culture but to keep them clean from 
weeds ; and place fome tall ftakes down by them, for 
their ftalks to twine about, otherwife they will ip re ad 
on the ground, and make a bad appearance. Thefe 
plants, if they are properly fupported, will rife ten 
or twelve feet high-, they flower in June, July, and 
Auguft, and will continue till the froft kills them. 
Their feeds ripen in autumn. 
The fifth fort grows naturally in Jamaica, from 
whence the late Dr. Houftoun fent me the feeds 5 
this fends out long branches, which twift about the 
4 D trees,
