526 WlEGAND : JUNCUS TENUIS WlLLD. 



leaves very long (two thirds the length of the stem) and commonly 

 stout, nearly terete, rarely much channelled ; sheaths usually all 

 more or less distinctly blade-bearing, very loose and broad, brownish 

 or purple, "margins and rounded auricles almost cartilaginous, not 

 scarious : inflorescence many-flowered, rather large and normally 

 diffuse, rarely contracted, 2-8 cm. long, more or less fuscous ; 

 bracts 5-15 cm. long, similar to the leaves, either longer or shorter 

 than the inflorescence ; bracteoles acutish, often fuscous : perianth 

 3.5-4 mm. long, the segments spreading, pungent, nearly equal 

 and similar, greenish-brown with a narrow scarious margin : sta- 

 mens one half the length of the perianth, anthers oblong, shorter 

 than the filaments : style very short : capsule ovate oblong, 

 rounded, minutely apiculate and very obscurely triangular at the

Very similar to /uncus tenuis but seems to differ strangely 

 from all other forms in the combination of pale fuscous flowers 

 and terete leaves, the latter character apparently being quite con- 

 stant. The sepals are strongly spreading as in J. tenuis, and it 

 also goes through the same characteristic variations as that species 

 in the condensation and expansion of the inflorescence. The ex- 

 tremes are quite unlike in appearance but not essentially different 

 in structure. Small stunted forms are also commonly wiry, 

 slender and strict with filiform leaves. This condition is well ex- 

 hibited by the two specimens from Lake Co., Fla. (Nash), which 

 are both low and very slender with narrow sheaths. They seem
