1. E. STRICTA Host. Stem simple or branched below, brandies 

 erect, often nearly as long as tlie stem, or shorter and sj^reading. Spikes 

 + stout, occupying the greater part of the stem and branches; inter- 

 nodes longer than the bracts below, usually shorter and hidden by 

 them aboye. Leayes and bracts S-9 mm. long ; upper bracts with 

 lanceolate or subulate, acute, aristate teeth. Setse none or fairly 

 numerous on the margins of the leaves and bracts and on the calyx,

Distinguished from E. horealis by its paler green colour, and by 

 the nari'ow teeth of the l)racts ; but forms occur which approach 

 E. hor&alis. 



At the tune of the publication of his monograph, Townsend had 

 not met witli British specimens of E. atricta, and subsequently sug- 

 gested that name, but with doubt, for plants with erect branches and 

 leaves which in other respects resembled E. nemorosa.
