Corny Oddities: Siamese
RL (Bob) Nielsen, Extension

Once in a while strange things occur in plants.
Over the years, I occasionally come across examples of corn kernels
that contain multiple embryos. The accompanying photos illustrate
an example of "Siamese Triplets" where three embryos
developed within a single kernel and, ultimately, developed into
three corn seedlings sharing the same endosperm reserves of the
mother kernel. These embryos appeared to be complete in the sense
that each exhibited not only a coleoptile (containing the first
few leaves) but also a radicle root. The three embryos were seemingly
connected to a common scutellar node.
