Asimina triloba (L.) Dunal. PAWPAW. (As Uvaria triloba.) New York: "Prof. J. Hall informs me that it grows at Lewiston ..." Torrey (1843). Ontario: "Rich low woods near the railway below Queenston Heights. Very abundant on Point Pelee and in the townships bordering Lake Erie, between that point and Amherstburgh. Doubtless not rare along Lake Erie, but not reported. (Macoun.)" Macoun (1883). "I had looked for it where I found it in 1877, at the foot of Queenston Heights, but the forest was cut away and the memory of its existence had passed from the people. By good fortune I had made the acquaintance of Mr. Roderick Cameron, foreman at Niagara park in the summer 1891, and, he being a close observer and a very good local botanist, I asked him to look out for the tree. He found it in flower somewhere between St. David's and the escarpment, where, I am unable to say, as I failed to find it," Macoun (1893). "Queenston Heights, Ontario (Macoun)" Day (1888).
