Ipomopsis, Micheli. From ipo, to strike forcibly, and 
opsis, sight ; alluding to the dazzling colour of the 
flowers. Linn. 5, Or. 1, Nat. Or. Polemoniacece. 
A very beautiful genus of plants, but rather diffi- 
cult to cultivate. The following is oUr mode of 
treatment : — About the end of July the seed should 
be sown very thinly in small pots, large sixties, 
well crocked, and filled with peat and loam, both 
sandy, and in equal parts, and placed in a cold 
frame, where the seed will soon vegetate, during 
which time the least possible water is given. 
When 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 caref^ully 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 re- 
main. 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 
longtime. Synonyme : \. Gilia pulchella.

Iresine, WilldenoTV. From eiros, wool ; referring to 
the woolly appearance of the branches. Linn. 22, 
Or. 5, Nat. Or. Amarantacece. The plants of this 
genus are very pretty, tind may be cultivated in 
sandy loam and peat, mixed with a little decayed 
dung. They increase from seeds by merely sowing 
them on a gentle hotbed.

Iris, Linn. From iris, the eye; alluding to the

Linn. 3, Or. 1, Nat. Or. Iridacex. The genus Iris 
has long been, as it still continues to be, a great 
favourite in the flower-garden. “ The sword- 
leaved sorts,” says Sweet, “ do best in a light 
loamy soil, 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 I. persica belongs, as /. alata, can- 
casica, reticulata, &c. The common bulbous species 
do well in common garden soil, the more sandy the 
better.” I. tuberosa is purgative, and I. versicolor 
and verna are used in the United States as cathartics.
