1 Mr. Ar. Bennett (J of B. xxxv. 1897, p. 249) characterizes the 

 following forms : 



1. cuspidata (La?st.) glumes elongated and cuspidate. 



2. virescens (And.) just the opposite to the last ; the gl. 



i the length of the fr. which is very symmetrically arranged. 



3. minor (Boott). The montane plant with the spikes attenuated 

 at the base. 



4. elatior (Bab.) var. Watsoni (Sy.). The lowland plant usually 

 with spikes stout, equal and continuous leafy bracts, and tall (3 5 

 ft.) st. 



Mr. Bennett records the hybrids C. aquatilisXsalina (X C. Grant ii, Ar. 

 Benn.) and C. aquatilis X elata (X C. hibernica, Ar. Benn.).
