It is the only prairie maple with pinnately
compound leaves, generally consisting of 3-5 oval to oblong leaflets, light green above and grey-green below, that turn a clear yellow in the fall.
Compound leaves are either palmately compound, pinnately
compound, or bipinnately compound.
These traits were: (1) leaf shape, calculated as the number of leaf lobes on one side of the longest leaf divided by the length of the longest leaf, on the pinnately
lobed rosette leaves 111 d after planting; (2) inflorescence diameter, measured on the primary inflorescence at flowering; (3) petal shape, calculated as petal lobe length divided by lobe width of a haphazardly selected flower on the primary inflorescence; and (4) flower color, quantified to the nearest 0.
Its long leaves (up to 1 m) are pinnately
compound and contain 10-20 pairs of leaflets, each [approximately equal to]40 [cm.
