 taper-pointed, longer than the obtuse pod; seeds not appendaged. Alpine 

 summits of the White Mountains, New Hampshire, and high northward. (Eu.) 



5. L. spicfi t;i, Desvaux. Leaves channelled, narrowly linear ; flowers in 

 sessile clusters, forming a nodding interrupted spiked panicle, brown ; sepals bristle- 

 pointed, scarcely as long as the abruptly short-pointed pod ; seeds merely with

3. JIJNCUS, L. RUSH. BOG-RUSH. 



Perianth glumaceous. Stamens 6, or sometimes 3. Stigmas 3. Pod 3- 

 celled (often imperfectly so at maturity), loculicidal, many-seeded. Chiefly 

 perennials, with pithy stems, and cymose, panicled, or clustered small (greenish 

 or brownish) flowers, usually produced all summer. (The classical name, from 

 jungo, to join, alluding to their use for bands.) 



# Scapes naked and simple from matted running rootslocks, many of them barren, 

 furnished with short leafless sheaths at the base : flowers in a sessile cymose panicle 

 produced from the side of the scape above the middle, fj-androus (except in No. 1 ) : 

 seeds not appendaged. 



1. J. effusus, L. (COMMON or SOFT RUSH.) Scape soft and pliant 

 (2 -4 high), finely striated; panicle diffusely tnuch-branched (sometimes closely 

 crowded), many-flowered; sepals green, lanceolate, very acute, as long as the 

 obovate very obtuse and pointless pod; stamens 3 or 6. Marshy ground;

* # Scapes, $-c. as in the preceding, but some of the sheaths at the base leaf-bearing ;
