latter calls it 4. discolor, 
Thuill, but it seems pro- 
bable thatThuillier's plant

has also published it 
(Deutsch. Gram.) under 
the name of 4. paludosa,

gured it in his ‘Icones 
Critice,’ vol. ii. fig. 280. 
In France, Grenier and 
Godron have united it 
with 4. discolor (Fl. de 
France, vol. iii. p. 508), 
under the name of Des- 
champsia Thuillieri; Bo- 
reau (Fl du Centre, n. 
2663) and Lloyd (Fl. de 
l'Ouest, p. 519) both de-- 
scribe it under Weihe’s 
name.
