Spicate is an uncommonly used word that describes something arranged in a spike or ear-like pattern. Instead of using this word, there are other synonyms that convey the same meaning. One alternative is the word "spiky," which describes something having or covered with spikes. Another synonym is "bristly," which means having long, stiff, and prickly hair or spines. "Corymbose" is another synonym that refers to an arrangement of flowers in a flat-topped or convex cluster. Lastly, the word "raceme" is another synonym that refers to an inflorescence with pedicellate flowers arranged along an elongated axis, the oldest flowers being towards the base.
