The question of circumstance
What is a leaf lobe?
Botanically speaking, a leaf lobe is a division, more or less deep, which may be rounded or pointed, of a whole leaf. Put another way, they are large indentations in the leaf’s perimeter. They are clearly distinguishable from “teeth”, which are small, regular indentations all around the leaf. The number of lobes varies from variety to variety. For ivy, you’ll usually find 3, 5 or 7 lobes. Sometimes, there are no lobes at all. This is particularly true of mature ivy leaves.
It’s also important to distinguish between lobes and leaflets: a lobe applies to a whole leaf (a single petiole), while leaflets are divisions of a compound leaf, with a petiole subdividing into petiolules each bearing a leaflet. Ivy has no compound leaf. All leaves are whole, more or less lobed.
