Hi Malina, I think you would describe the leaves of Lady’s Mantle as something like this: Broadly rounded, palmately lobed and pleated leaves with strong veins. That is quite complex and they do look special. I looked it up in my Wildflower guide to help with this, and Pleated is the part I haven’t thought of before. I think that describes it quite well. Could also mention the special water-pumping / water-drainage cells at the leaf margins, the ones that ooze droplets of fluid when the plant is full of water. Those are called Hydathodes.
