Comment
Monopodial inflorescences, such as a raceme inflorescence (PO:0030115), have a centrally-located main axis; this axis is a first order inflorescence axis. In contrast, sympodial inflorescences, such as the riphidium inflorescence (PO:0030131), do not have a centrally-located main axis. The basal-most portion of a first order inflorescence axis is referred to as a peduncle (PO:0009053).
