Group 1a: tiny pores very evenly distributed and with weak rays
pores tiny, numerous to uncountable, rays are not present or barely visible growth ring boundaries visible to the naked eye due to color change from latewood to earlywood and what appears to be marginal parenchyma some of the species here have pores in radial multiples |
Group 1b: tiny pores very evenly distributed plus rays visible with a 10X loupe
pores numerous, tiny, and in often in radial multiples growth ring boundaries visible to the naked eye due to color change from latewood to earlywood, very thin line of marginal parenchyma is often visible with a 10X loupe, rays present but sometimes not distinct even with a 10X loupe and never with the naked eye |
Group 1c: sparser pores than groups 1a and 1b
pores relatively sparse and somewhat larger than groups 1a and 1b, growth boundaries are very vague, rays present but barely visible at 10X |
Group 1d: sparse pores with vasicentric parenchyma
pores sparse and fairly large and with vasicentric parenchyma rays that are barely visible with a 10X loupe, not visible to the naked eye |
Group 2a: dendritic pore patterns
pores in radial multiples in dendritic patterns without any accompanying lighter surrounding tissue, rays are present but not visible even with a 10X loupe growth ring boundaries generally visible due to color change from latewood to earlywood and some thickening of the groups of pores at the earlywood |
Group 2c: dendritic pore patterns (holly)
growth rings very faint, just barely visible to the naked eye, pores small, numerous, and in radial multiples, generally in dendritic groups, rays sometimes strong, sometimes barely visible even with a 10X loupe |
Group 2d: dendritic pore patterns (chittamwood aka gum bumelia)
growth rings usually bold, sometimes vague, pores tiny and multitudinous but not evenly distributed; rather, they are grouped in thick dendritic groups, rays present and plentiful but often not visible even with a 10X loupe |
Group 2e: dendritic pore patterns (buckthorn)
growth rings usually bold, sometimes vague, pores tiny and multitudinous but not evenly distributed; rather, they are grouped in thin dendritic groups, rays present but not visible even with a 10X loupe |
Group 3: strong rays (see also: live oak in the dendritic groups above have strong rays)
rays clearly visible with a 10X loupe, usually visible to the naked eye growth ring boundaries weak but visible to the naked eye pores numerous and tiny |
Group 4a: lozenge shaped aliform parenchyma
lozenge shaped aliform parenchyma rays strong and numerous but thin so only visible with a 10X loupe growth rings faint to invisible, even with a 10X loupe pores fairly sparse and frequently in radial multiples of 2 or 3 |
Group 4b: lozenge shaped aliform parenchyma with confluent parenchyma bands
lozenge shaped aliform parenchyma with confluent parenchyma bands rays numerous and clearly visible but only with a 10X loupe pores fairly dense and occasionally in multiples of 2 growth rings very hard to distinguish even with a 10X loupe |
Group 5: confluent parenchyma
strong confluent parenchyma bands rays numerous and clearly visible but only with a 10X loupe growth rings often very hard to distinguish |
Group 6: misc
