should now stand as Q. Californica (Cooper). The oldest speci- 
fic name for Quercus tinctoria, Bartram (1791), is Q. velutina, 
Lamarck, published two years previous, in 1789. There are, in 
fact, two names older than Bartram’s, as Aiton in Hortus Kewen- 
sis (1789) published the name Q. discolor for the Quercitron. 
In Garden & Forest ii., 471, Professor Sargent gives Quer- 
cus cuneata, Wangenheim (1787), as the earliest reliable speci- 
fic name for Michaux’s Quercus falcata, passing over Mar- 
shall’s (1785) two names, Q. rubra digitata and Q. rubra mon- 
tana, on account of the general vagueness of the descriptions. 
Mr. Sudworth points out the advisability of inquiring if there is 
not sufficient reason for adopting Marshall’s Quercus nigra digita-
