Propagated by cuttings.

Bignonia (Trumpet Flower). Bignoniaceæ.

Increased by seeds or layering, or, in early spring, by cuttings made from good strong shoots with two or three joints. Place cuttings of tender sorts in a well-drained pot of sandy soil, under a bell-glass, in bottom heat. Also by seeds. B. radicans propagates readily from root-cuttings.

Billardiera (Apple Berry). Pittosporeæ.

Increased by seeds, and by cuttings placed in a pot of sandy soil, under a bell-glass, in gentle heat.

Billbergia. Bromeliaceæ.

Propagated by suckers which are taken from the base of the plant after flowering, when they have attained a good size. The best method to adopt is as follows: Take the sucker in the hand and gently twist it off the stem; next, trim the base by the removal of a few of the lower leaves, and then insert each sucker separately in a small pot, in sharp soil. A bottom heat of about 80° will greatly facilitate new root growth; failing this, they will root freely in the temperature of a stove, if placed in a shaded position for two or three weeks, after which they will bear increased light and sunshine during the latter part of the day.
