Leaves are arranged
in whorls of 6-8 and are sessile to the stem, lanceolate 1¼ inches long leaves are bristle-tipped and
finely toothed or rough on the margin. The
leaves and stems, when crushed, emit a very
pleasant odor of new-mown hay.
Gaillum is derived from the
Greek word, gallon which was the name of the
plant described by Dioscorides as one used for
curdling milk.
