The gray-green to blue-green leaf blade is 19 to 42 millimeters long and 10 to 18 millimeters wide. The leaf tips are curved in the extension of the leaf axes or outwards. The tip is 0.4 to 16 millimeters long. The leaf margins and the keel are colored like the leaf blade or are darker. The leaf tips are slightly reddish brown. The smooth leaf surface is sometimes visibly lined.
