Leaves obovate, petiolate, narrowed rather abruptly towards the almost hastate-cordate base, acute at the apex, 6–8 in. long, 2–4 1/2 in. broad; petiole about 2 in. long. Peduncle more than 2 in. long; bracteoles acute, stated to be “ovate, 3/4–1 in. long and 3/4–1 1/4 in. broad,” and “to enclose the corolla-tube, which is about 7 lin. long, to the middle” (the dimensions seem incorrect). Corolla-lobes about 3/4 in. long. Stamens with filaments only 1 lin. long; anthers 2 1/2 lin. long. Style about 8 lin. long. Fruit described as 3 in. in diameter and nearly 2 1/4 in. in length, grooved at the middle, with the remains of the style above.
