Commonly called Chakte Kok (with a multitude of variant spellings), this species has been previously placed in the Sickingia genus. Another species thats also in the Rubiaceæ family is Cosmocalyx spectabilis, which is typically sold interchangeably as Chakte Kok. A third, botanically unrelated wood (Erythroxylaceæ family), which bears an uncanny similarity in nearly every respect to the two other species is Erythroxylum havanense, which is most commonly sold as Redheart.
Aptly named, in some instances freshly surfaced Redheart can be a very bright, watermelon redthough color can vary in intensity and hue from board to board: anywhere from a light orange/pink, (similar to Pink Ivory), to a darker brownish red. In some cases, it can look quite similar to Bloodwood, though usually with a more visible and figured grain pattern. Redhearts vibrant color quickly fades to a reddish brown in direct sunlight, though this color change can be slowed (but usually not stopped entirely) by using a finish with UV inhibitors, and keeping the wood away from strong lighting.
