My interest is in dividing corms which would probably be post fruiting since doing more than remove pups before would, I assume, result in no flowers.

Plants may also be propagated but [sic] dividing up a corm, much like a potato, and planting the "eyes" or small pups which are forming. (Bolding is mine.)

These are some ARH photos, each corm is ringed by hundreds of GP's and each GP can produce many pups.

Other meristems are also located at various points around the corm, when these sprout they form their own pseudostems and these are what become suckers. In many plants, the apical meristem produces a hormone which discourages the growth of too many extra shoots (called "apical dominance"), if you destroy the apical meristem it will break this dominance and allow other shoots to grow out. Many of the buds for new suckers are already formed on the plant, they are just being inhibited until the plant gives them permission to grow.

Here is a diagram taken from Simmonds book, what he labels as "gp" (growth point) is the meristem, as well as the same corresponding area on the sucker.
