Like many trees in India, the kattus and its parts have multiple uses. The wood is used to make windows, doors, and furniture. And kattus leaves are used for growing orchids. We also encounter wild berries like sil timmur and hisalu, a Himalayan raspberry. And gharia sisnu, a kind of nettle, useful for heart problems. Rhododendron trees are scattered along the path. Chhetri points to a vine that looks like a snake hood—the nagbeli. He says locals have named many plants for the way they look, like the "athane jaar," which resembles a 50 paisa coin.
