The gray, white speckled, fibrous, scaly bark with a smooth top remains permanently on the entire trunk and short strips detach from it. The moderately straight trunk grows to about half of the final height and can reach a chest height diameter of 0.5 meters. It has a branched treetop .
In young specimens, the leaf blade of the stalked leaves is 5 to 10.5 centimeters long and 5 to 10 centimeters wide, egg-shaped (ovate) to circular (orbicular) and blue-green, gray-green, blue-gray or grayish. The stalked leaves on older trees have a 7 to 16.5 centimeter long and 1.7 to 4.3 centimeter wide, lanceolate (lanceolate) or broadly lanceolate to egg-shaped and entire leaf blade that is matt blue-green, gray-green, blue-gray to grayish .
