The leaves have long, flender footftalks , and 
they are narrow, and of the fhape of a {pear- 
head ; bearded at each fide, near the bafe, 
The flowers are fmall and yellowifh. 
It is common on dry banks, flowering in June. 
C. Bauhine calls it Acetofa arvenfis lanceolata. 
Authors have, from the varieties of its growth, 
idly divided into two fpeciess as they have de- 
fcribed alfo under the name of a diftinét f{pecies, 
the common forrel, when of a more than ordinary 
ftature. 
3. Round-leaved Sorrel. 
Lapathum acetofum rotundifolium. 
The root is fibrous and creeping. 
The firft leaves have long footftalks, of a pur- 
plifh tinge; and they are rounded in their gene- 
ral fhape, but auriculated at the bafe. 
The ftalk is a foot high, flender, and of a pale, 
greyifh green; as are alfo the leaves. 
The flowers are {mall and brownifh. 
It is common in our northern counties; and, 
being cultivated in the rich mould of a garden, 
becomes the plant called Roman forrel, or round- 
leaved garden-forrel. 
Ray calls it Acetofa rotundifolia repens. Others, 
Acetofa Romana.

Pr‘HE flower confifts of eight filaments contained, together with three ftyles, and a neétarium of 
eight granules, in a cup: this is formed of a fingle piece, divided into fegments ; which being thin 
and coloured, appear as petals, but remain with the feed, which is large, fingle, and three-cornered. 
Linneus places this among the offandria trigynia. 
‘1. Buckwheat. 
Fagopyrum vulgare. 
The root is fibrous. 
The ftalks are light, hollow, upright, yel- 
lowifh, and a yard high. 
The leaves ftand fingly at diftances: they fur- 
round the ftalk at the bafe, and have there two 
ears, and terminate in a point. 
Their colour is a faint, yellowifh green. 
The flowers are white, with a dath of purple; 
and they ftand in tufts at the top of the ftalk. 
The feeds are brown. 
It is found by road-fides in fome places, but 
probably owing to feattered feeds, the plant be- 
ing cultivated for the food of cattle. 
C. Bauhine calls it Evy/inum Theophrafti folio 
hederaceo, Others, Fagopyrum eretium vulgare.
