DIVISION I. 
i; Narrow-leaved Crefs. 
Najlurtium anpiftifolimii. 
The root is long, thick, white, and furnifhed 
with many fibres. 
The leaves that rife from it are oblong, and 
narrow, and form a little thick tuft : they are of 
a pale green, cut in deeply at the edges, and 
fliarp-pointcd. 
The ftalk is round, thick, firm, upnght, very 
much branched, and a foot or more in height. 
The leaves ftand thick upon it, and m a per- 
feftly irregular manner ; they are oblong, nar- 
row and of a pale green : they have no foot- 
ftalks i they are not at all indented at the edges, 
and they terminate in a fbarp point. 
The flowers ftand at the tops of the branches 
in little clufters, and they are very fmal! and 
white. , r J 
The feed veffels are fliort and hard ; tl:c iecds 
are large and brown. 
The whole plant has a ftrong acrid tafte. 
It is common bv the road-fides in Effex, and 
fome other parts of the kingdom, though utterly 
unknown in many counties. It flowers m July. 
C Bauhinc calls it Nafturlium fyhejlrs ofyndis 
folio. Others, Tblafpi angujtifoltum, and TUaffi 
minus. 
The plant in its general afpedhas much of the 
appearance of the ammon gm-den-crefs, efpecially 
while the radical leaves remain ; but they are ge- 
nerally of fliort continuance, fading as the plant 
flowers. 
2. Rock Crefs. 
Ni'jlurlium pumilium petraun. 
The root is flender, oblong, and lurniflied 
with a great number of fmall fibres. 
The firft leaves rife in a fmall round tuft: they 
are oblong, narrow, and very deeply finuated at 
the ed-'es ; fo that they have much the appear- 
ance of the pinnated divifion : they are of a pale 
green at their firft growth, but they foon become 
'"'The ftalks rife among thcfe feveral together ; 
they are round, flender, upright, and about four 
inches high. 
The leaves on them are very fmall and tew 
fometimes they are altogether naked, and there 
are rarely more than two or three on the ftalk 
when the plant is moft vigorous and healthful : 
thefe are ftiort, and deeply divided into three or 
four fegments. . ,• , r 
The flowers ftand at the top in a little tult, 
and they are very fmall and white. 
The feed-veflfel is fliort, and the feeds are very

but there are ufually found on the tops of the 
ftalks clufters of the feed-vetTcls, which get a 
brown colour. 
It is not uncommon in barren hilly places. It 
flowers in April. 
Tabcrnamontanus calls it Nafturlium petr^ciim % 
a name moft have copied : but fome call it Burfa 
pq/loris minor. 
3. Rocket-Crefs. 
Najiurtium foliis erucv. 
The root is long, flender, white, and furniflied 
with many fibres. 
The firft leaves grow !n a little tuft, and are 
oblong, and deeply divided in the pinnated man- 
ner ; they are of a faint green, and of a tender 
fubftance. 
The Italk is round, firm, upright, branched, 
and a foot high.

but they are fmaller, narrower, and more divided; 
the fegments are very flender, a little waved, and 
pointed at the ends. 
The flowers are fmall, and ftand in tufts at the 
tops of the branches. 
The feed-vefli^ls are alfo fmall, and the feeds 
are brown. 
It is found on fome hilly paflures, and flowers 
in Auguft. 
C. Bauhine calls it Nafiurtium fyhajlre eritc^ 
ajjine. Others, Erucn mjturtio cogmta tenuijolia. 
It has much the afpedt in general of the rocket 
kind. 
4. Fine-leaved Crefs. 
Ndfturtium foliis temtijfune diz-ijis. 
The root is a fmall, oblong fibre, with a few 
very flender threads hanging from it in various 
parts. 
The firft leaves rife Irregularly, a few in a 
clufter, and are of a pale green : they are oblong,

The ftalks rife in the midft of this tuft, and 
are numerous, weak, flender, and very much 
branched. 
The flowers are fmall and white : they ftand 
at the tops of the branches in little clufters. 
The pods are fliort and very fmall, and the 
feeds are minute and yellowifh. 
It is found on the hilly paftures in the weft of 
England, and among rocks. It flowers in May.
