sandy, and in equal parts, and placed in a cold
frame, where the seed ivill soon vegetate,
during -which time the least possible water is
given. "Wlien the plants begin to show signs
of leaves, they are thinned out to three or four
in each pot ; in about a week after this, they
should be removed into a rather light and airy
part of the greenhouse, where they remain all
winter. During winter, over-watering, and
drips from the roof of the house, must be
carefully avoided. In spring, they are shifted
into forty-eight-sized pots, well drained, and
the same kind of soil as before ; in doing this,
great care must be taken not to injure the
roots. In this sized pot they will generally
be found to flower. Out of the four plants
left after thinning, it is rare that more than
two remain in each pot, one of which may be
destroyed if the other appears healthy and
well established ; if not, let both remain. In
the course of their growth, water cannot be
too cautiously given, especially just before the
plants break into flower. Thus nourished, in
an airy situation near the glass, they flower
splendidly in July and August, and continue
beautiful for a long time. Synonymes : 1,

IRIS, Linn. From iris, the eye ; alluding to
the variety and beauty of the colours of the
flower. Linn. 3, Or. 1, Nat. Or. Iridàcece,
The genus ìris has long been, as it still continues
to be, a great favourite in the flowergarden.
The sword-leaved sorts, as I. germánica,
&c., do best in a light loam, and
increase freely by suckers from the roots, or
by seeds. The tuberous-rooted ones are more
difficult to cultivate, and thrive best in a
mixture of loam, peat, and sand, as does also
the tribe to which /. pérsica belongs, as I.
alata, caucásica^ reiiciilàta, &c. The common
bulbous species do well in common garden
soil, the more sandy the better. I. titheròsa
is purgative, and I. versicolor and vérna are
used in the United States as cathartics. Synonymes
