In botany, a spike refers to a type of inflorescence (flower arrangement) that bears taller-than-average flowers, most usually on an axis that is unbranched. Similar to a raceme, the spike bears flowers that are directly attached to the plant, without any stalks whatsoever.

Besides, what is a Raceme flower?

ˈsiːm/ or /r?ˈsiːm/) or racemoid is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called pedicels) along its axis. In botany, an axis means a shoot, in this case one bearing the flowers.

Thereof, how does Raceme differ from Spike?

In context|botany|lang=en terms the difference between raceme and spike. is that raceme is (botany) an indeterminate inflorescence in which the flowers are arranged along a single central axis while spike is (botany) a kind of inflorescence in which sessile flowers are arranged on an unbranched elongated axis.

What is meant by Cymose?

cymose inflorescence (cyme; definite inflorescence) A type of flowering shoot (see inflorescence) in which the first-formed flower develops from the growing region at the top of the flower stalk (see illustration).
