Naftunium fupiimn caffulis wrrmofts. 
The root is long, Qender, white, and furniflied 
\t'ith many fibres. 
The firfl: leaves fpread themfelves beautifully 
upon the ground, forming a regular circle : they 
are long, moderately broad, and very deeply di- 
vided in the pinnated manner, and their colour 
is a frcth and pleafant green : the fcgments are 
narrow, and divided into three points, or notched 
on each fide at the end. 
The fi:a!ks are numerous, round, green, and 
divided into many branches : they are thick and 
firm -, but they do not rife up from the ground, 
fpreading themfelves every way like the leaves. 
The flowers grow in clufters in the bofoms of 
the leaves, and they are finall and white. 
The feed-veflcls are fliort and rough : the feeds 
are fmall and brown. 
It is common evety where by way-fides, and 
flowers in May. 
C. Bauhine calls it Amhrofia campejirji repats. 
Others, Coroncpus Ruellit. 
All thefe crelTcs are good againfi: fcorbutic

government purchafcd of Mrs. Stevens for the 
.cure of the ilone.

Najlurtium foliis variis. 
The root is long and fiender, and has numc; 
rous fibres. 
The firfi leaves are long, narrow, and vari- 
oufiy and irregularly divided ; they are of a frefh 
green colour, a tender fubftance, and a pleafing 
acrid tafie. 
The ifalk is round, upright, firm, and of a 
whicidi green, not much branched, and two teet 
high. 
The leaves on this arc numerous, and placed 
irregularly : tUey are divided in the pinnated 
manner into narrow fegments, very varioiifly 
and irregularly, as thofe at the root j but the di- 
viiions of ihefe are narrower. 
The flowers ftand at the tops of the ftalks and 
branches, and are fmall and white. 
The fecd-veiTels are alio rmail : the feeds are 
brown. 
It is a native of Germany, but is fown in- our 
gardens for the ufe of the table, the feed-leaves 
bc'ing excellent among what is called young fal- 
C. Bauhine calls it NaJlurHum fyheftre vutga- 
lum. Others, 'Najlurtium hortenfe. 
Culture occafions a great deal of variety in the 
leaves of this plant. 
We fee them fometimes curled in a very beau- 
tiful manner at the fides, and fometimes undi- 
vided and broad, without fo much as indentings 
at the edges. Under thefe appearances it has 
been defcribed by Ibme as two diftindt fpecies, 
but they are only varieties. 
The plant is of the nature of the feveral wild 
crejj'es, and is no way to be taken more properly 
than as a fallad.

THE flower is compofed of four petals placed crofs-ways : they are fmall, and of an inverted oval 
form, with very narrow bottoms. The cup is formed of four little leaves, which ftand fome- 
what open : they are oval and hollow, and fall with the flower. The feed-veiTel is broad, Ihort, and 
coroprcffed ; it is narrow at the bafe, and broadeft at the extremity : the feeds are numerous. 
LinnEEUS places this among the teir adynamia ftlkulofa i the flower having four longer and two fiiorter 
threads, and the feed-vefiel being a regular filicule. 
He joins the fliepherds purfe to this genus, but without reafon. The feed-veflel in that plant is 
of a very particular form ; therefore we have feparated it, and defcribed it in its place : and we 
have here joined feveral proper thlafpi to the reft, which Linnaeus feparates under various names.

The ftalk grows in the centre of thefe, and they 
grow yellow, and decay as it rifes in height : it is 
firm, round, of a pale green, and a little hairy, 
and toward the top divides into feveral branches. 
The leaves on it are long, narrow, and fharp- 
pointed : they are broadefl: at the bafe, and there 
adhere to the ftalk with a kind of appendage or 
point on each fide ; and from this part they grow 
fmaller all the way to the end.
