Which inflorescence is found in Spike?
raceme
In inflorescence: Indeterminate inflorescence. A spike is a raceme, but the flowers develop directly from the stem and are not borne on pedicels, as in barley (Hordeum). A spike is a raceme except that the flowers are attached directly to the axis at the axil of each leaf rather than to a pedicel (see photograph).

Why is the capitulum important to the Asteraceae?
