I noticed this vine last month only because of the small yellow flower, about 1/4-inch across with 5 narrow notched hairy petals, 5 green somewhat pointed sepals, and yellow stamens and styles. The leaves are overall round with three deep lobes and irregular edges. Found in Austin. Any ideas much appreciated.
