12 years ago At the POC meeting on 6-19-12, this new term was accepted, with some modifications to the comment.
Definition: A plant structure (PO:0009011) that is a proper part of a multi-tissue plant structure (PO:0025496) and includes portions of plant tissue (PO:0009007) of at least two different types.
Revised comment: Includes cardinal parts of plant organs (PO:0025001) as well as parts of other multi-tissue plant structures. Cardinal refers to the fact that these are biologically meaningful and not arbitrary parts. Most cardinal parts of a multi-tissue plant structure have both fiat and bona-fide boundaries, including parts with large fiat boundaries, such as leaf base (PO:0020040) or fruit distal end (PO:0008001), and parts with primarily bona-fide boundaries, such as leaflet (PO:0020049).

If we decide to add a new term for multi-tissue plant structure, which would be parent to plant organ but also things like seed (https://sourceforge.net/tracker/?func=detail&aid=3530843&group\_id=76834&atid=835555), we could use a term for "cardinal part of multi-tissue plant structure". This would be similar to "cardinal plant organ" (or cardinal part of plant organ) but could multi-tissue parts of multi-tissue plant structures that are not organs (e.g., aril, which is part of seed). It would also serve as parent to things like ovary, which can be part of either an organ or a collective plant structure.
