straw-color, about the length of the minutely pointed brown pod. (L. melano 

 carpa, Desv. ) — Mountains, Maine, W. Massachusetts, N. New York, and north 

 ward. July. — Stems 1°- 3° high, scattered. (Eu.) 



* # Flowers crowded in spikes or dose dusters. (Plants 6' -12' high.) 



3. la, canipestl'is, DC. Leaves flat, linear ; spikes i-\2, somewhat um 

 belled, ovoid, straw-color, some of them long-peduncled, others nearly sessile ; 

 sepals bristle-pointed, longer than the obtuse pods ; seeds witli a conical appen- 

 dage at the base. — Dry fields and woods ; common. May. (Eu.) 



4. Ii. ni'Cliata., Meyer. Leaxtes channelled, Wnmr; spikes S-b, on unequal 

 often recurved peduncles, ovoid, chestnut-brown ; bracts ciliate-fringed ; sepals 

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

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



5. li. spicata, Desvaux. Leaves channdled, narrowly linear ; _;?6w)ers tw 

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

 pointed, scarcely as long as the abruptly shor^pointed pod ; seeds merely with 

 a roundish projection at the base. (Our plant is L. racemosa, Desv. ? according 

 to Godet.) With the last, and more common. (Eu.) 



3. S'tfiCVS, L. Rush. Bog-Rush. 



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

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

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

 or brownisli) 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 rootstocks, many of them barren, 

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

 produced from the side of the scape above the middle, 6-androus (except in No. 1 ) : 

 seeds not appendaged. 



1. J. eflfusiis, L. (Common or Soft Rush.) Scape soft and pliant 

 (2° -4° high), finely striated ; panicle diffusdy much-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; 

 everywhere. (Eu. ) 



2. J. filiforiniS, L. Scape slender (l°-2° high), pliant; panicle few- 

 flowered, simple; sepals green, lanceolate, acute, rather longer than the very 

 obtuse but short-pointed pod. (J. setaceus, Torr. Fl.) — Wet banks and shores, 

 N. Now England to Michigan, and northward. (Eu.) 



3. J. BrUliCllS, Willd. Scape rigid (2° -4° high), from a very strong 

 rootstock; panicle ascending, loose, dark chestnut-colored ; sepals ovate-lanceolate, 

 the 3 outer sharp-pointed, as long as the elliptical rather triangular pod. — Sandy 

 shores of New England and of the Great Lakes ; thence northward. (Eu.) 



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

 the leaves terete, knotless, like the continuation of the scape above the panicle : sta- 

 mens 6.
