218 BOTANY. 
468. The ovule-bearing flowers consist of the well-known 
cones which, when mature, bear the seeds (Fig. 122). The 
cone consists of a stem bearing many leaf-like scales 
closely crowded together, and upon these the ovules are 
produced. Each ovule has one coat which grows up from 
below, almost covering it; but as the ovules grow they bend

464, The embryo-sac appears in the body of the ovule, 
when the cone is quite small, as an enlarged cell. It soon 
forms a mass of cells (the endosperm, or rudimentary first 
stage) within itself, and in this are developed one, two, or 
more rudimentary archegones, each with its germ-cell,
