Leaves
The leaves are unique among seed plants, being fan-shaped with veins radiating out into the leaf blade, sometimes bifurcating (splitting), but never anastomosing to form a network. Two veins enter the leaf blade at the base and fork repeatedly in two; this is known as dichotomous venation. The leaves are usually 5–10 cm (2-4 in), but sometimes up to 15 cm (6 in) long. The old popular name "maidenhair tree" is because the leaves resemble some of the pinnae of the maidenhair fern, Adiantum capillus-veneris.
Leaves of long shoots are usually notched or lobed, but only from the outer surface, between the veins. They are borne both on the more rapidly growing branch tips, where they are alternate and spaced out, and also on the short, stubby spur shoots, where they are clustered at the tips.

Famous quotes containing the word leaves:
“Leaves and bark, leaves and bark,
To lean against and hear in the dark.
Petals I may have once pursued.
Leaves are all my darker mood.”
—Robert Frost (1874–1963)
“How could it be so fair, and you away?
How could the Trees be beauteous, Flowers so gay?
Could they remember but last year,
How you did Them, They you delight,
The sprouting leaves which saw you here,
And call’d their Fellows to the sight,
Would, looking round for the same sight in vain,
Creep back into their silent Barks again.”
—Abraham Cowley (1618–1667)
“One does not arise from such a book as Sister Carrie with a smirk of satisfaction; one leaves it infinitely touched.”
