In August 1933 the writer observed.an unusually vigorous specimen of Colocasia antiquorum, var. esculenta (known commonly as elephant's ear or caladium) growing in a yard in Falmouth, Kentucky which is located in the northern portion of that state. At the close of each growing season the tuber is taken up by the owner and placed in his cellar. The original tuber is about twenty years old and has of course given rise to many small tubers in addition to its twenty or more crops of huge leaves.
