#### Note
There is evidence that Gay privately published a *Synopsis* de la *flore* de la *Mitidja* et des montagnes qui l'entourent... Crescia, in two parts (1893, 1895), but we have not seen a copy nor have we learned sufficient details to describe it. We suspect that this is either a reprint or otherwise derived from a series of articles with the same title published in Rev. Sci. Bourbonnais 3: 129-140, 206-216, 280-288. 1890, Id. 4: 36-45, 160-169. 1891 (fide Anon., J. Bot. 29: 94. Mar 1891; Anon., Bull. Soc. Bot. France 39(RBC-D): 181. 5 Jan 1892).
