Ash Twig


Close up of Ash twig: Photograph taken through the microscope.

AS WE TOOK my mum to the doctor’s last Thursday I picked up this Ash twig, blown down in the recent gales, in the car park. Even such an unpromising subject has a lot of interest if you look at it closely; with all those scars and cracks it could be the stem of a palm tree.

The gash at the end show where it was wrenched from the tree by the wind, while three pairs of oval scars near the tip show where the Ash’s compound leaves sprouted last spring.

The lenticular pore in my photograph below is just 4 millimetres, less than a quarter of an inch, across. It’s close to the point where the twig was attached and I’m guessing that it’s a pore, an opening in the bark layer, rather than a leaf scar.
