What is the difference between a pedicel and a peduncle? As i think about it,
a pedicel is a determinant flowering branch (ie., the meristem of the branch is
"used up" in the production of the flower. A peduncle (flowering stalk) is an
indeterminant branch. It has an active apical meristem which gives rise to
bracts and branches (pedicels). The peduncle meristem may eventually develop
into a pedicel at the end of its growth term, or just die at the tip (as in
Aloe).
Did I get this right?
Ther must be other plants with "non-bracteoid" flowering stalks similar
to Pinguicula. How about _Pyrola_ and/or other dwarf members of the
Ericaceae? Could these offer insight into the Pinguicula predicament?
