One of the cell types found in xylem, the water conducting tissue of plants; typically found in angiosperms but absent from most gymnosperms such as conifers; main feature distinguishing the "hardwood" of angiosperms from the "softwood" of conifers.
Pit membranes between xylemvessels play a major role in angiosperm water transport.

Occasionally BNYVV antigen was detected predominantly, but not exclusively in the xylemvessels.
3
The fungus was however detected in xylemvessels, bark and inside the pith twelve weeks post-inoculation.
4
P. aleophilum was additionally detected in the lumen of xylemvessels in which tyloses blocked its progression.
5
Immunolocalization studies showed the enzyme to be localized extracellularly, in the secondary cell wall of xylemvessels and phloem fibers.
6
Tolerant clones showed a colonization pattern restricted to roots and a limited number of xylemvessels only in the stem base.
7
Given their proximity to xylemvessels, we suggest that xylary chloroplasts may play a role in light-dependent repair of embolized xylemvessels.
8
Beneath, the epithem is composed of a lacunar and highly vascularized parenchyma offering a direct connection between leaf surface and xylemvessels.
9
Taken together, our results indicate that oxytetracycline translocation mainly occurs via xylemvessels, and that movement into the phloem occurs subsequent to xylem translocation.
