[J. alpinus (Vill.), having an acute dorsal angle to the sheaths 
of its leaves and blunt segments to its perianth which are mucro- 
nate below their summit ; — also J. ofrafa.s (Krock.), having “ more 
deeply striated leaves ” than either of the 2 preceding species 
and the inner segments of the perianth about as long as the ca])- 
sule ; will probal)ly be found in Britain.]
