Proposed def.: A parenchyma cell (PO:0000074) that is part of a portion of secondary xylem parenchyma (PO:0004532).
part_of secondary xylem parenchyma
ray wood parenchyma cell (PO:0004527):
Current def.: Parenchyma cell of a ray in secondary xylem.
Rename "ray secondary xylem parenchyma cell", with "ray wood parenchyma cell" as a synonym.
Proposed def.: A parenchyma cell (PO:0000074) that develops from a ray initial (PO:0000082) and is part of a portion of ray secondary xylem parenchyma (PO:0004534).
part_of ray secondary xylem parenchyma, develops_from ray initial
upright wood ray parenchyma cell (PO:0004528)
Current def.: Ray cell in secondary xylem oriented axially (vertically in the axis) with its longest dimension.
Rename "upright ray secondary xylem parenchyma cell", with "upright ray wood parenchyma cell" as a synonym.
Proposed def.: A ray secondary xylem parenchyma cell (PO:0004527) that is oriented with its longest dimension parallel to the plant axis (PO:0025004) in which it is found.
add broad synonym 'upright cell'
procumbent wood ray parenchyma cell (PO:0004529)
Current def.: Ray cell within secondary xylem having its longest axis in radial direction.
Rename "procumbent ray secondary xylem parenchyma cell", with "procumbent ray wood parenchyma cell" as a synonym.
Proposed def.: A ray secondary xylem parenchyma cell (PO:0004527) that is oriented with its longest dimension radial to the plant axis (PO:0025004) in which it is found.
add broad synonym "procumbent cell"
axial wood parenchyma cell (PO:0004526)
Current def.: Parenchyma cell in the axial system of secondary xylem.
Rename "axial secondary xylem parenchyma cell", with "axial wood parenchyma cell" as a synonym.
Proposed def.: A secondary xylem parenchyma cell (PO:0004525) that is part of a portion of axial secondary xylem parenchyma (PO:0004533).
