Into 4 tall Collins glasses, add 1 tablespoon maple syrup, about 10 mint leaves, 3 to 4 lime wedges and 2 lychees. Just before your guests arrive, muddle together to bring out the flavors.
When your guests arrive, fill each glass with crushed ice, 1 tablespoon lychee liqueur and 2 tablespoons rum. Then fill the glasses the rest of the way with club soda, garnish with a sprig of mint and serve.
