Which term best describes a seed head that does not branch and has tiny flowers attached directly to the main stem?

Explanation:
A seed head that doesn’t branch and has tiny flowers attached directly to the main stem is a spike. The key feature here is an unbranched axis with flowers seated directly on the stem (sessile), with no pedicels. If the inflorescence were branched, it would be a panicle. If the flowers were on short stalks along the axis, it would be a raceme, and if all flowers came from a single point like spokes of an umbrella, it would be an umbel. So the description matches a spike.
