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:
“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)
“An agnostic position is one that leaves open the question whether there exists a god or gods, professing to find such a question unanswered or unanswerable. For the atheist, the question has been answered, and in the negative.”
—Jaroslav Pelikan (b. 1923)
“Laid out for death, let thy last kindness be
With leaves and moss-work for to cover me:
And while the wood-nymphs my cold corpse inter,
Sing thou my dirge, sweet-warbling chorister!
For epitaph, in foliage, next write this:
Here, here the tomb of Robin Herrick is.”
—Robert Herrick (1591–1674)
