Leaves rather sharp-edged. 



Stems broad, compressed, leafless, as well as the leaves of 

 comparatively soft texture ; leaves extremely long, very 

 broadly linear, somewhat turgid, hardly rigid, smooth; 

 the lowest floral leaf already short ; spikelets in a very 

 elongated somewhat spreading panicle, slightly pointed ; 

 floral bracts of this and other species occasionally almost 

 distichous ; rudimentary sepals and petals of about one- 

 third the length of the fruit. (Possibly a variety of the 

 preceding.) L. exalt at um.

1942. Spikelets in a comparatively short and rather con- 



tracted panicle. 



Maritime ; stems leafless, sharp-edged, much compressed ; 

 leaves hard, almost ensate, the floral leaf already quite 

 short ; panicle dense ; spikelets mostly ellipsoid, pointed ; 

 fruit turgidly ovate. "Sword-Rush." L, gladiatum. 



Spikelets in a much elongated and rather spreading 

 panicle. 



Sylvan, very tall ; stems leafless, much compressed, sharp- 

 edged ; leaves very long, ensate-linear ; floral leaves much 

 abbreviated, passing gradually into bracts ; branches of 

 the panicle often turned to one side and somewhat bent 

 downward ; spikelets mostly ellipsoid, pointed ; fruit 

 globular-ovate. L. elatius. 



1943. Stems almost blunt-edged. 



Stems leafless, flat ; leaves elongated -linear ; spikelets never 

 very numerous, clustered in a contracted panicle, very 

 short, globular-ovate ; rudimentary sepals and petals 

 shorter than the fruit. L. globosum. 



Stems rough- or sharp-edged ... ... ... ... 1944 



1944. Rudimentary sepals simply pointed. 



Stems leafless, flat or slightly convex on one side, rough- 

 edged ; leaves rather long, broad-linear, the lowest floral 

 leaf occasionally elongated ; spikelets in a contracted 

 rather short panicle ; rudimentary sepals and petals 

 always shorter than the fruit. L. viscidum.
