HEMLOCK

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 hemlock

• parenchyma:
• rays: multitudinous, very thin, barely visible at 10X
• growth rings: generally, an obviously gradual transition from light colored earlywood to dark colored latewood and then a very sharp transition from the end of the latewood to the beginning of the next year's earlywood.
• resin canals:
