IxiA, Linn. Ixia, bird-lime ; because of the
viscid nature of some of the species. Linn. 3,
Or. 1, Nat. Or. Iridaeece. A genus of very
handsome plants when in flower. We recommend
them to be grown in a mixture of
sandy loam and decayed leaves, or peat soil.
When they have done flowering, they require
no water till they begin to grow afresh. In
October, they should be fresh potted, and set
in a cool frame, as they only require to be protected
from frost till their pots are well filled
with roots ; then they may be set on the shelves
of the greenhouse, and watered regularly, and
they will flower well. The species of this
genus, and some other bulbous-rooted genera,
succeed best in a pit, covered with lights in
very cold or wet weather. Most of the species
will grow well in a south border, in the open
air, planted from five to six inches deep, in a
light sandy soil, near a wall, and to be covered
with dry litter in severe weather ; they will
then flower much stronger than if grown in
pots, and they may be increased by ofl'sets
from the bulbs, or by seeds. See Babidna,
Hesperdntha, Spardxis^ Synnotia, and Trichonema.

syringe while growing. They propagate from
cuttings in sand, or sandy soil, under a glass,
