If the stalk of the individual spikelet is a pedicel, then what is the stalk
of the entire inflorescence?  And, what about grasses that have
single-flowered spikelets, e.g., Zizania?  Is the stalk of the spikelet then
a pedicle and the stalk of the inflorescence a peduncle?

A grain of wisdom would come in handy about now.
