Arabis thaliana? Linn., Sp. PL, (1753), Stsymbrium thalianum 
2Tt is incorrect to write the second name thaliana with a capital letter. 
Linnaeus used such capital letters for the trivial names of old genera 
reduced by him form their original standing. Thus, e. g. Erysimum Barbarea 
meaning the Erysimum that formerly constituted the genus Barbarea. 
There is no record of any application of a genus Thaliana. Moreover even 
Linnaeus does not write the name Arabis Thaliana as the manual makers 
would have us believe but Arabis thaliana Linn. Sp. Pl., l. c. It is there- 
fore, a falsehood to attribute the name to him, but such things are frequently 
done and often with questionable motives. (See Am. Mid. Nat., II., 97) 
(Britton and Brown Flora III., II., 197 [1913]). The plant was so named 
in honor of Thalius who first described it. (1. c.)
