THE GENERIC NAME PHRAGMITES. 
M. L. FERNALD. 
In recent years there has been so strong a tendency to overthrow 
the long familiar name Phragmites for the reed, in favor of Trichoon, 
that it seems important to point out the claims of the former. The 
error of taking Trichoon Roth! (1798) instead of Phragmites has arisen 
through starting the latter name from the publication by Trinius? 
in 1820. Thus, when Trichoon was brought to the front by Rendle’, 
he took it up because it antedated Phragmites 'Trin. Similarly Schinz 
& Keller* and Schinz & Thellung®, in 1909, retained Trichoon as 
antedating Phragmites Trin. But it is important to note that, al- 
though in 1899 Rendle dated Phragmites from the publication by 
Trinius in 1820, in 1907 he* again took up Phragmites as dating from 
Adanson” (1763); and, more recently, Hitchcock? has discussed the 
status of the name, although part of his discussion is unconvincing. 
Adanson’s publication was characteristically abbreviated: Phragmi- 
tes was included in his 3d Section of the Grasses, in which “ Tous ont 
plusieurs fleurs hermaphrodites, rassemblées en forme d'épi dans un 
` calice commun, qui n'a que 2 bales” (p. 33); and in the “Table” 
(p. 559) he supplies the following information :
