C. americanus, the American smoketree,[1] chittamwood or American smokewood, is a rare species of flowering plant in the genus Cotinus of the family Anacardiaceae, native to Oklahoma, Texas, Arkansas, Missouri, Alabama and Tennessee. It is a deciduous, conical shrub growing to {{convert|10|m|abbr=on}} tall by {{convert|8|m|ft|0|abbr=on}} broad, with oval leaves up to {{convert|12|cm|0|abbr=on}} long. It produces panicles of pink-grey flowers in summer, and its foliage turns a brilliant scarlet in autumn; considered by many to be the most intense fall color of any tree. The smokey effect derives from the clusters of hairs on the spent flower stalks.[2] It is highly sought after and cultivated in botanical gardens world wide.[3][4] The Latin specific epithet obovatus means "in the shape of an inverted egg", and refers to the broadly oval shape of the leaves. The heartwood is a bright yellow. The species may be facing extinction in the wild.
