The lines seen on natural timber are called "grain." Timber grain refers to the arrangement and appearance of wood fibers, which can vary significantly between different species of trees. The grain patterns result from the growth rings and the way the wood cells are structured, influencing both the aesthetic and physical properties of the wood.
They are perpendicular and one diagonal is bisected.
According to Wikipedia: A diagonal can refer to a line joining two nonconsecutive vertices of a polygon or polyhedron... See the related link for more detail.
The diagonal direction of fabric is called the "bias." It runs at a 45-degree angle to the threads of the fabric, allowing for greater stretch and flexibility compared to the straight grain or cross grain. This characteristic makes bias-cut fabrics popular in garment construction, as they can drape more fluidly and fit the body's contours better.
diagonal
The grain - is the pattern in the wood, showing the direction of the fibres.
Timber is stronger across the grain than along the grain.
The direction of the grain in timber significantly impacts the strength of the wood. Wood is strongest along the grain, so a piece of timber with the grain running parallel to the load will be stronger than if the grain runs perpendicular to the load. This is because the fibers in the wood provide more support and resistance to forces acting along the grain.

For the tree's timber, a common name is 'honeysuckle'. It is a beautiful timber, carrying a complex grain of ribbons.

In exchange, the Greeks got grain, timber, and metal.
they resist stress and spread the load over the length of the board
The Greeks traded fish for products such as grain timber flax.
