OAK, BURR

Quercus spp.


A NOTE ABOUT OAKS IN THE USA AND EUROPE



Quercus spp. of the family Fagaceae, including at least the following: Burr oak is in the white oak group of oaks, and it is one that often has particularly long rays that make for very long ray flakes on quartersaw surfaces, as you can see in some of the pics below.

my samples:
NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K)
colors will vary under other lighting conditions


both sides of a sample plank of bur oak / Quercus macrocarpa --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. "Bur" is about as common a spelling for the common name as is "burr"

for this one, I took this extra pic of the other end because it shows quite nicely how LONG the rays can be in this species.


END GRAIN UPDATE from directly above although I see I got it upside down

burr oak plank --- both sides; as you will see from the end grain shot of the smaller plank below (cut from this one) this plank is almost perfectly quartersawn, thus the large ray flakes.
