Character: Highly variable in texture and color, it contains knots, sapwood and brownish discoloration resembling red heartwood.
Knot: Group knots are permitted as well as intergrown branch knots up to a diameter of 10 mm.
Sapwood: It is permitted up to the half of the slat width. Bluish stain of natural origin, near a frost rib is permitted.

Character: It is characterized by accentuated colors, red heartwood, knots and a vivid texture.

Character: Characterized by knots, conspicuously different in color from the background, and bold color variations between individual lamellas and also within lamellas, the latter resulting from drying.
Knot: Groups of knots are permitted, up to a diameter of 8 mm.
Red heartwood: Basically not permitted, but may occur in traces.

Character: It is characterized by the knots and the prominent textural and color variations resulted from the discolorations near the pith. Flame pattern is permitted.
Knot: 5 – 6 healthy and dark knots – even grouped ones – are permitted in each stripe, up to a diameter of 40 – 50 mm. Fallen-out knots are permitted, up to 40 mm in diameter when corrected by filling.
