From Hawaiian Annual, Hilo Fifty Years Ago, by J.M. Lydgate (published in 1923, this refers to events of 1873):
A bunch of the largest bananas ever produced in Hawaii, according to the report of the government experiment station, was taken to the mainland this past summer by Dr. W. E. Slater, grown by him at his home on Dole street, and destined for Minneapolis.
The individual bananas averaged eight inches in length and three inches in width, and the entire bunch weighed seventy-three pounds. There have been heavier bunches of more hands of the ordinary sized fruit, though this may be the record, as stated, for individual bananas. Unfortunately the kind or variety was not given.
