...In the example of Figure 2, a and b are considered to be spikes, and d is usually considered to be solitary in the axil of a leaf, even though it can be considered that the leaves in the inflorescence simply degenerated from d to a. Because of many such contradictions, Turol puts emphasis on the presence or absence of terminal flowers, and proposed a classification method in which those with terminal flowers are monotelic inflorescences and those without are polytelic inflorescences (Figure 3).
