Hello fron Botany Bay where I went away from London for the day.
To find peace with the elements.
Just when the sun hid behind a cloud....
Nature has the power to heal and re-energise you.
So here I am with my beloved pooch Zeppelin.

Because of the greater production of xylem, the vascular cylinder is dominated by radially arranged rays of secondary xylem interspaced with medullary rays of parenchyma cells.
Conspicuous resin ducts are found in the cortex, primary and secondary xylem, but rarely the pith. The ducts are surrounded by secretory parenchyma that produces resins and many toxic terpenes including the turpentines. This antiseptic material solidifies when exposed to air, acting to seal wounds, to protect the plant from fungi, insect and bacterial infection and to discourage herbivores. Some secretory cells enlarge into dark staining tyloses that block the resin dusts.
