Color/Appearance: Heartwood tends to vary in color from a pink or yellow to a darker reddish brown, with darker brown streaks common. White to pale yellow sapwood clearly demarcated from heartwood. Color tends to darken with age. Bobgunnia madagascariensis tends to be more on the reddish or orangish side, while B. fistuloides tends to be a more subdued brown.

Workability: Generally easy to work despite its density, though cutting resistance can be high, and the wood has a tendency to burn while being drilled. Planes fairly well despite having interlocked grain (typically only slightly interlocked). Turns, glues, and finishes well.

Grain/Texture: Grain tends to be wavy or interlocked. Uniform medium to coarse texture, with a high natural luster.

Endgrain: Diffuse-porous; medium-large pores in no specific arrangement; solitary and radial multiples of 2-3; heartwood gum deposits common; growth rings indistinct; rays not visible without lens; parenchyma aliform (lozenge and winged), confluent, and banded.

Rot Resistance: very durable regarding decay resistance, and is also resistant to insect attack. Pau Rosa has good weathering characteristics in outdoor applications.

Common Uses: Veneer, carvings, furniture, turned objects, and other small, specialty wood items.

Comments: Pau Rosa is one of only a handful of woods that have the potential of being nearly rainbow-colored; its appearance is reminiscent of Tulipwood or Canarywood.
