You can see the leaflets come out of the thick clumps of flower/seed heads. A good match for the shapes of the leaflets.
But the leaves are elliptical (and soft, like lamb's ears). I don't know if there is an association between this and something that might be mnemonic for star-shaped leaves. I haven't come across one so far.
