Gleditsia aquatica Marshall

Gleditschia aquatica, Marsh Arb. Amer. 54 (1785).
This, I believe, is the oldest available name for the Water
jLocust of the Southern States. To be sure, as pointed out by.
Prof. Greene, (BULLETIN, xvii. 14), it was called G. inermis by
Crantz, (Inst. Rèi. Herb. 1. 219 (1766), and this name was sub-
sequently used for the tree by Miller and K. Koch ; but Linnaeus
published a G. inermis in Syst. Nat. Èd. 10 (1759), as cited in
Richter’s Codex, p. 1012, and repeated it in Sp. PI. Ed. 2, 1059
(17^3)- Although this G. inermis of Linnaeus was, apparently,
a composite species made up of one from Java and the North
American G. triacantkos, the reference to the Javanese tree
by him stands first, and the species is said to come from Java.
Hence we are not justified in using the same binomial published
seven years later for a different plant.
