The leaves are of two kinds, primary and secondary; the primary are
thin, deciduous scales, in the axils of which the secondary leaf-buds
stand; the inner scales of those leaf-buds form a loose, deciduous
sheath which encloses the secondary or foliage leaves, which in our
species are all minutely serrulate.
