Exotic Woods
Birdseye Maple – The figure is reportedly caused by unfavorable growing conditions for the tree. The Sugar Maple attempts to start numerous new buds to get more sunlight, but with poor growing conditions the new shoots are aborted, and afterward a number of tiny knots remain. Birdseye Maple is frequently sold in veneer form, but solid lumber is available as well. Being tiny knots, the birdseye figure is most noticeable and pronounced on flatsawn pieces of lumber. 
Black Palm – Black fibers embedded in a lighter tan or light brown colored body. Fibers are more densely packed toward the outside of the tree trunk, becoming more and more sparse toward the center of the tree. The center core of the tree is soft and contains none of the darker vascular bundles that give the wood its characteristic look and hardness. (This is nearly opposite of the typical outer sapwood/inner heartwood combination found in dicot hardwoods.) 
Bocote – Has a yellowish brown body with dramatic dark brown to almost black stripes. Color tends to darken with age. Also, the grain patterning can be quite striking, particularly on flatsawn areas. It’s not uncommon to see many “eyes” and other figuring in Bocote: though unlike knots, they do not seem to present any special challenges in machining.
Brazilian Rosewood – Can vary in color from a darker chocolate brown to a lighter purplish or reddish brown, with darker contrasting streaks. The black streaks can sometimes form a unique grain pattern that is sometimes referred to as “spider-webbing” or “landscape,” very similar to Ziricote. Lighter yellowish sapwood is clearly demarcated from the heartwood
Bubinga – Heartwood ranges from a pinkish red to a darker reddish brown with darker purple or black streaks. Sapwood is a pale straw color and is clearly demarcated from the heartwood. Bubinga is very frequently seen with a variety of figure, including: pommele, flamed, waterfall, quilted, mottled, etc
Cocobolo – Cocobolo can be seen in a kaleidoscope of different colors, ranging from yellow, orange, red, and shades of brown with streaks of black or purple. Sapwood is typically a very pale yellow. Colors are lighter when freshly sanded/cut, and darken with age
Ebony – Ebony is a dense black wood, most commonly yielded by several different species in the genus Diospyros. Ebony is dense enough to sink in water. It is finely-textured and has a very smooth finish when polished, making it valuable as an ornamental wood.
Lace Wood – Has a very conspicuous flecking that gives this wood its namesake. The wood itself is a reddish brown with grey or light brown rays, which result in a lace pattern when quartersawn. Like other woods that exhibit the strongest figure in quartersawn pieces, (such as Sycamore), Lacewood has the most pronounced figure and displays the largest flecks when perfectly quartersawn; this is due to the wood’s wide medullary rays, whose layout can be seen the clearest when looking at the end grain.
Mesquite – Mesquite Wood Characteristics:
Somewhat straight grained but often wavy. Mesquite trees are short desert plants that yield boards with knots, splits, worm holes, etc. Woodworkers use the defects as points of interest in the finished pieces.
Olive Wood – Heartwood is a cream or yellowish brown, with darker brown or black contrasting streaks. Color tends to deepen with age. Olive is sometimes figured with curly or wavy grain, burl, or wild grain.
Padauk – Heartwood color can vary, ranging from a pale pinkish orange to a deep brownish red. Most pieces tend to start reddish orange when freshly cut, darkening substantially over time to a reddish/purplish brown (some lighter pieces age to a grayish brown
Purple Heart – When freshly cut the heartwood of Purple Heart is a dull grayish/purplish brown. Upon exposure the wood becomes a deeper eggplant purple. With further age and exposure to UV light, the wood becomes a dark brown with a hint of purple. This color-shift can be slowed and minimized by using a UV inhibiting finish on the wood.
Tulip Wood – Heartwood is streaked with yellows, reds, oranges, and pinks. Color and figure can be highly variegated.
Walnut Burl – A burl results from a tree undergoing some form of stress. It may be caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Such burls sometimes appear as groups of bulbous protrusions connected by a system of rope-like roots. Almost all burl wood is covered by bark, even if it is underground. Insect infestation and certain types of mold infestation are the most common causes of this condition.
Zebra Wood – Heartwood is a light brown or cream color with dark blackish brown streaks vaguely resembling a zebra’s stripes. Depending on whether the wood is flatsawn or quartersawn, the stripes can be either chaotic and wavy (flatsawn), or somewhat uniform (quartersawn).
