The on top and bottom of the same color dull gray - green leaf blade to middle-aged specimens is elliptic to ovate, straight, entire. The petioles of adult specimens are narrow flattened or channel-shaped. The on top and bottom of the same color dull gray - green leaf blades of adult specimens are lanceolate, curved like a sickle, relatively thin, tapering to Spreitenbasis back and have a pointed upper end. The barely visible lateral nerves go into an acute or obtuse angle from the midrib. The cotyledons ( cotyledons ) are in two parts.
