In this way a simple stemwith its garniture of leaves is de-veloped from the seed. But besidesthis direct continuation, buds may form and develop into lateral stems, thatis, into branches, from any node. The proper origin of branches is fromthe Axil of a leaf, i. e. the angle between leaf and stem on the upper side;and branches may again branch, so building up the herb, shrub, or sooner or later, and without long delay in an annual like Flax, insteadof this continuance of mere vegetation, reproduction is prepared for by. fio. 8,. IJpper part of Flax-plant in blossom. u A PATTERN PLANT. [SECTION 2. 15. Blossoming. In Flax the flowers make their appearance at theend of the stem and branches. The growth, which otherwise might con-tinue them farther or indefinitely, now takes the form of blossom, and issubservient to tlie production of seed. 16. The Flower of flax consists, first, of five small green leaves,crowded into a circle: this is the Calyx, or flower-cup. When its sepa-rate leaves are referred to they are called Sepals, a name which distin-guishes them from foliage-leaves on the one hand, and from petals on theother. Then come five delicate and colored leaves (in the Flax, blue), whichform the Corolla, and its leaves are Petals ; then a circle of organs, in
