VEGETATIVE REPRODUCTION 157 
shoot in the old bulb during the resting period. The food 
that was destined for the flower is diverted and used in 
the production of numerous small bulbs. Lilies, hya- 
cinths, etc., are regularly propagated by this method. 
The scales of the hyacinth are also slit up, and when 
placed in a warm, moist atmosphere as many as a hundred 
tiny bulbils may be formed along the cut edges, and 
after several seasons these become big flowering bulbs.

In the narecissus (Fig. 60) the scales are numerous and 
tightly packed ; they are the bases of old foliage-leaves. 
The flowering shoot and young foliage-leaves are again 
situated in the centre of the bulb, but after flowering the 
food passes into the bases of the leaves, and the upper 
parts die away, leaving broad, jagged, membranous ends. 
In this way the original bulb gradually increases in size, 
and may persist for several years. A bud in the axil of 
one of the central foliage-leaves becomes the flowering 
shoot of the succeeding year. The narcissus multiplies 
by the formation of new bulbs, which arise as buds in the
