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



3. Li. campcstris, DC. Leaves flat, linear ; spikes 4 -12, somewhat um- 

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

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

4. It. arcilfita, Meyer. Leaves channelled, linear ; spikes 3 - 5, on unequal 

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

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

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



5. It. spicata, Desvaux. Leaves channelled, narrowly linear ; floiccrs in 

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

 pointed, scarcely as long as the abruptly short-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. JIJNCUS, L. RUSH. BOG-RUSH. 



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

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

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

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

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



# Scapes naked and simple from malted running rootstocks, many of them barren, 

 furnished with short leajless sheaths at the base : flowers in a sessile ci/mose 

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

 seeds not appendaged. 



1. J. e fills US, L. (COMMON or SOFT RUSH.) Scape soft and pliant 

 (2 -4 high), finely striated; panicle diffusely 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. filiformiS, L. Scape slender (l-2 high), pliant; panicle few- 

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

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

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



3. J. BaltlCUS, Willd. Scape riijid (2 -4 high), from a very strong
