2. Yellow-flowered Raphaniftrum. 
Raphanifirum flore luteo. 
The root is long, flender, white, and furnithed 
with many fibres. 
The firft leaves are large and oblong : they are 
broadeft at the bafe, finuated at the edges, and 
fharp-pointed ; and they are fupported on fhort 
footftalks : they are rough to the touch, and of 
a deep green. f 
The ftalk is round, upright, firm, two feet 
and a half high, and divided into many branches. 
The leaves on it are numerous : they: are placed 
irregularly, and they refemble:thofe from the root:

Dwarf Raphaniftrum, 
Raphaniftrum humile foliis divifis. 
The root is. a fmall, white fibre; little more. 
The firft leaves are oblong, narrow, and fharp- 
pointed : they are deeply divided at the edges; in 
the manner’of pinnated leaves, but not quite to 
the rib. * 
The ftalks are numerous, flender, Weak, and 
not more than five or fix inches high: they ge- 
nerally trail upon the ground two thirds of their 
length, 
The leaves on them: are. few, fo that they ap-

The flowers ftand at the tops of the ftalks and 
branches, and they are finall and yellow.” 
The pods are long, and moderately thick : 
they are jointed, and of a pale green, and, when 
ripe, they break afunder at the joints, 
The feeds are round, large, and brown. 
It is common in corn-fields, and flowers in 
July. 
Ray calls it Rapiftrum flore lute filiqua glabra

The flowers are fmall and ‘yellow, and they 
ftand in tufts at the tops of the ftalks. 
The feed-veffel is long and jointed, and the 
feeds are {mall and brown, 
It is a native of Siberia, and flowers in June. 
Gmelin calls it Raphanus foliis pinnatis pinnis 
confluentibus Jfiliquis teretibus articulatis. The 
whole plant has greatly the afpect of the wild roc- 
ket in miniature. 
The feeds of the white rapanhifirum are {aid to 
operate powerfully by urine; but there is not cer- 
tain authority for it.- The virtues of the others 
are not known, They are very troublefome to

SISYMBRIUM. 
mPHE flower is compofed: of four oblong petals, which are difpofed croffwife, and have very fmall 
~ bottoms': the cup’ is ‘formed: of four little, narrow leaves: thefe fpread tolerably open, and 
are coloured and) the whole’ falls with the flower: the feed-veffel is crooked and fhort; and the 
membrane that divides it within is fomewhat longer than the two fides: the feeds are numerous 
and fmall. 
Linneus places this among the tetradynamia filiquofa; four of the fix threads in the flower being 
longer than the other two; and the feed-veffel a regular pod: but he very improperly joins 
with the watercreffes many plants not allied to them: thefe we fhall give under other regular genera, 
and in their proper places. 
#. Common Watercrefs; 
Sifymbrium vulgare. 
Theroot is long and creeping: it runs under 
the mud, and has tufts of fibres at {mall diftances. 
The firft leaves are long and pinnated: each 
is compofed of two or three pairs of pinne, with 
a large leaf at the end; and thefe {eparate pinnz 
are fhort, broad, and have no foottftalks. 
The ftalks are round or flatted, and of a pale 
green: they are ftriated, weak, and very much 
branched : they are’ pinnated, ‘as thofe frem the 
root, but the pinnz are fomewhat fimaller. 
The flowers are little and white: they ftand in 
fmall tufts, and at the tops of the ftalks and 
branches. 
The feed-veffels are flender, and not very long; 
and the feeds are {mall, and brown. 
Ne Xxy, 
It is common in fhallow waters, and flowers in 
May. 
C. Bauhine calls it Nafturtium aquaticum fupi- 
num. J. Bauhine, Sifymbrium cardamine five Naf- 
turtium aquaticum, 
It is an excellent antifcorbutick. 
The juice of it is given in {pring with that of 
brooklime, and fome other plants of the fame cha- 
racter; but it has more virtue than them all. 
This is at beft an unpleafant method of taking it: 
it is very agreeable, eaten asa fallad; and there 
is no way in which it better exerts its virtues. 
It opens obftructions, operates by urine, and 
promotes the menfes. Many medicines of great 
name, and naufeous tafte, are inferior to this 
little plant in feorbutick diforders.
