Winter-character reference to 
Oxydendrum arboreum: — Schnei- 
der, f. 123. 
The generic name Oxydendrum 
was given to what Linnaeus had 
called Andromeda arborea _ be- 
cause of its acidity. Though a 
pure Greek derivative, its author Latinized the name by chang- 
ing the ending on of the Greek into wm in accord with a gen- 
eral effort to Latinize all plant names, of whatever deriva- 
tion,—and a correction of this kind has been made in many 
though not all cases where the author of a name did not do 
this himself. Curiously, the established Latinized name of 
this tree is sometimes written in on. 
Twigs glabrous, olive or bright pink. O. arboreum.
