DescrlpNom--Leaves very variable in size and outline, palmately
3 to 5 lobed. Lobes conical, obtusely rotmded.
Sinuses open, shallow, rounded. Margin entire except basally,
where incipient lobations cause undulations. Petiole long and
stout. Midrib stout, more or less curved or flexuous. Primaries
3 to 5 from the base, prominent, running to the tips of the
lobes. Secondary branches very slender, camptodrome. The
middle lobe is usually longest and broadest, and the basal lateral
lohes may be reduced to subordinate and but sl?ghtly n:'arked
divisions of the main lateral lobes.
A's can be readily seen, the relative development of the apical
or basal lobes and the depths of the intervening sinuses greatly
alters the appearance of these leaves. Some are quite symmetrical,
while others are very unsymmetrlcal; some are pre-eminently
3-lobed and sublobate, others are 5-lobed with additional
incipient lobes. The variations are almost exactly corn-
