摘要
The tube systems known to exist in tracheophytes are xylem, phloem and laticifers which are composed of living or non-living cells and secretory ducts/canals and aerenchyma that is of schizogenous or lysigenous origin. Here, we describe a novel type of tube network of unknown function that ramifies through the olive tree bark and is composed of groups of apparently empty, anastomosing tubules interrupted by perforated plates; side openings of the tubules connect them to the intercellular spaces of the cortex.
