Different sestivation in sepals and petals of the same flower is quite frequent, as in the Mallow (Pig. 134). 208. Inflorescence, or Flower-arrangement, relates not only to the flowers on the stem of the plant, but also on the flower-stalk. Plower- buds, like leaf-buds in regard to the stem, are Axillary (Pea, Wis- taria); Terminal (Oleander); Latent; and Adventitious (Fig. 135). One difference must be noted, however: The terminal and axillary leaf-buds continue to grow year by year, developing into stems and branches ; the flower-bud has nothing to do with this vegetative stem- growth ; its sole function is to perform the work of reproduction;. Fia. 133.—Magnolia glauca. A, torus, allowing spirals of scars left by the fallen stamens; pistils in spirals on its apex. B, ripe cone, with sds. hanging by cobwebby white threads.
