Polygalàceoi. All the species of this geims
ai-e very showy. The greenhouse kinds thrive
well in one part turfy loam, and three parts
peat, with a quantity of sand mixed iu it.
To obtain cuttings fit^for planting, the shoots
should be topped, which will cause them to
push out numerous young ones ; these should
be taken off close when in a growing state,
about three inches long, planted in pots of
sand under glass, and placed in the propagating
house ; the glasses must be occasionally
taken off and wiped. The hardy perennial
kinds thrive in a peat soil, and increase freely
by seeds or divisions of the roots. The annual
kinds require sowing in the open ground, preferring
a peat soil. The root of P. Senega is
diuretic, expectorant, purgative, emetic, and
sudorific ; it has been used with success in
croup, and as a cure against the bite of venomous
reptiles. According to Barton, P. sanguinea
possesses similar qualities. Synonymes:
