Woody Dicot Stem: in Starch Sheath in One Year Tilia
cross section: Tilia one year
magnification: 100x
Berkshire Community College Bioscience Image Library
Greater annual production of xylem results in a vascular cylinder dominated by well-defined annual rings of secondary xylem interspaced with narrow medullary rays of parenchyma cells. Each annual ring consists of large thin walled spring vessels that taper into progressively smaller, thick walled vessels and tracheids characteristic of later season wood.
The deepest zone of primary xylem is separated from the parenchymatous central pith by a starch sheath of dark staining starch filled parenchyma cells.
