DIFFUSE POROUS HAWTHORN

NOTE: unless otherwise specifically stated, all of the images shown on this
page are of 1/4" square end grain cross sections shown at 12X with the top
of the image towards the bark and the bottom towards the pith so that
earlywood is towards the bottom of the growth rings and latewood is towards the top

general characteristics of hawthorn end grain

• pores: generally uncountable
• parenchyma: none to consider
• rays: numerous but barely visible even with a 10X loupe
• growth rings: growth ring boundaries range from clear to weak/vague but in any case are usually discernible to the naked eye

The white dots on some of these are dust specks, not a feature of the wood
