The base of the leaf may be cordate or heart-shaped when the outline of its rounded base is tErned in forming a sinus where the petiole is attached; auricled or eared, when with a pair of small projections at the base; sagitate or arrow-shaped when the ears or lobes are acute and turned downwards; hastate when the acute basal lobes point outwards and oblique or inequilateral when the two sides of the base are unequal or not at the same level A peltate or skield-shaped leaf has the petiole attached to the lower surface and towards the center of the blade some distance from the base, the ribs or veins of the leaf radiating from the point of insertion, the leaf appearing somewhat like an umbrella.

Question

What is the type of leaf margins in these figures?

The base of the leaf may be cordate or heart-shaped when the outline of its rounded base is
tErned in forming a sinus where the petiole is attached; auricled or eared, when with a pair of small
projections at the base; sagitate or arrow-shaped when the ears or lobes are acute and turned
downwards; hastate when the acute basal lobes point outwards and oblique or inequilateral when the
two sides of the base are unequal or not at the same level A peltate or skield-shaped leaf has the
petiole attached to the lower surface and towards the center of the blade some distance from the base,
the ribs or veins of the leaf radiating from the point of insertion, the leaf appearing somewhat like an
umbrella.
