sub-section of the Lily family, but its Nat. 
Order is JuNcace&, which includes also the 
two genera Luzula and Juncus.

natives of the bog; all of them love wet. 
The most common species which have to be 
distinguished are /. glaucus, J. squarrosus, J. 
acutiflorus, or articulatus, J. obtusifiorus, J. con- 
glomeratus, and the rather handsome /. lam- 
procarpus. Again let the novice beware of 
confusing the Bulrush, scerpus lacustris, with 
this family, /zzcws; all the latter have flowers 
with a 6-parted parted perianth star-like when 
open; the Sczrpus genus, Nat. Ord. CYPERACEs, 
have no perianth, but stamens and ovaries 
covered by glumes in small brown heads.
