Leaves are oblong, 6-14 cm long, 3-7 cm wide, not lobed, nearly heart-shaped at the base, with double-toothed margins, smooth or sparingly velvety above. Flowers are scarlet or red. Sepal tube is short-cylindric-bellshaped, up to 2 cm long, purple above, pink or white below, the inner rank tubular, filamentose only at the margin, white. Ovary is yellowish-velvety. Red Passion Flower is native to South America.
