Tt is a native of Italy, and flowers in June. 
C. Bauhine calls it Eruca latifolia. 
All thefe plants agree in their general quali- 
ties as well as external form. They are good 
in obftructions of the) vifcera, and in fcorbutie, 
diforders ; but they have not been fufficiently 
regarded in the practice of phyfic.

"THE flower is compofed of four petals, regularly difpofed crofs-ways: they-ate broad at the ends; 
and have fmall bottoms of the length of the cup. The cup is formed of four little leaves 3 they 
are oval, blunt, and converge at the points, and the whole falls with the flower’: the feed -vetel ig 
long, and of a rounded form, and contains two cells ; the dividing membrane is a litdlé’ longer than 
the fides of the pod: the feeds are numerous and oval. i : 
Linnzus places this among the ¢efradynamia /filiquofa ; four of the fix threads in the flower being 
longer than the other two, and the feed-veffel being a regular pod. 
Some of the plants of this genus produce a kind of foboles, or fruitful lumps, in the’ bofome of 
the leaves ; but this is not univerfal. 
1. Trifoliate Toothwort. 
Dentaria triphyllos. 
The root is thick, of an irregular figure, and 
lies obliquely under the furface. When young it 
is white, but when older it is black on the out- 
fide ; fo that the common appearance is its being 
white in fome parts, and black in others: it is 
compofed in an irregular manner of feveral dif- 
tinct parts oddly conneéted together. 
From the different parts of this root rife feve- 
ral footftalks, on each of which are placed three 
leaves: thefe are broad, fhort, and of a deep 
green, ferrated at the edges, pointed at the ends, 
’ and each has its feparate pedicle, by which it is 
fixed to the common footftalk. 
Jn other parts of the root lie the rudiments of 
the ftalk, which therefore rife in feparate places. 
Thefe are round, flender,. of a pale green, and 
about a foot high. 
Toward the middle of the flalk, or fomewhat 
nearer the top, there ftand three footftalks, each 
fuftaining three leaves: thefe are long, narrow, 
dharp-pointed, and ferrated at the edges. 
The flowers are moderately large: they have 
Jong and flender pedicles, fo that they com- 
monly hang drooping; and their colour is a 
greenifh white. 
The fecd-veffels are long and flender, and the 
feeds are numerous and {mall, 
It is a native of Italy, and other warmer parts 
of Europe, and flowers in July. 
C. Bauhine calls it Dentaria triphyllos. Co- 
lumna, Ceratia Plinii, Others in general, Den- 
daria trifoliata, Three-leaved toothwort, 
2. Seven-leaved Toothwort. 
Dentaria beptaphylla. ; 
The root is placed obliquely in the ground, and 
is compofed of a number of odd-fhaped irreoular 
parts, fixed in a rude manner to one another. 
The firft leaves are large, and very beautiful : 
they ftand on long, flender footftalks, of a greenifh 
white, or of a redifh colour; and are of a pin- 
nated form, each confifting of three pairs of pinnss 
with an odd leaf at the end. : 
Thefe are oblong, narrow, tharp-pointed and 
ferrated at the edges, : 
The ftalk is round, flender, ic c 
and a foot high. a gies 
The leaves grow irregularly on thefe, and in 
an uncertain form: the lower part of the ftalk js 
naked, and that ufually half way up: at this 
height begin the leaves, three or four of which 
ftand at fome fmall diftances over one another; 
and are of the pinnated form, like thofe from the 
root, but having fewer Pinne: above thefe {tand 
feveral fimple, oblong, and narrow leaves, and 
at the top the flowers in a {mall fpike. aud 
Thefe are large, and of a beautiful pale redith 
hue. 
‘The feed-vefiel is long and flender, and the 
feeds are numerous and round, : 
In this fpecies there“are frequently little cu- 
bercles at the bofoms of the leaves, like thofe of 
the bulbiferous faxifrage, which fa'ling take root, 
and become new plants. : 
It is common in all the fouthern parts of Eu- 
Tope in fhady fituations at the foot of hills. It 
has been found ip fome places~ in England i
