Gladiolus is an example of which inflorescence type?

Explanation:
Gladiolus shows a spike inflorescence. The flowers line up along a single, unbranched flowering stalk (the scape) and are attached directly to the stem with little or no stalk of their own. This creates a continuous vertical column of blooms from bottom to top. This differs from a raceme, where each flower sits on its own noticeable pedicel along the axis; from an umbel, where all flower stalks radiate from a single point like an umbrella; and from a corymb, where varying stalk lengths level the floral arrangement into a flat-t topped cluster. The direct attachment along a single axis in Gladiolus is what makes it a spike.
