JUNCACE,E. 



JUNCUS. 



Stem 10-15 inches high. Leaves rather distantly nodose, terete-compressed, usually one 

 near the middle of the culm and another near the base. Panicle more or less compound ; the 

 branches slightly spreading. Heads mostly about 3-flowered, but sometimes more, rarely 

 less. Leaflets of the perianth very acute, but not cuspidate. Style distinct. Capsule narrow, 

 with flattish sides, chestnut-color and shining when ripe. Seeds with a subulate appendage 

 at each end. 



Sandy borders of lakes, and in bogs : frequent. 



7. Juncus pelocarpus, E. Mey. Brownish-fruited Mush. 



Slem erect, bearing a single leaf, compressed ; leaves setaceous, compressed, obscurely 

 nodose ; panicle pyramidal, spreading ; heads about 2-flowered ; leaflets of the perianth oblong, 

 obtuse, the inner ones a little longer, shorter than the triquetrous-ovate capsule {Kunth). — 

 E. Mey. syn. Luz. p. 30 ; Kunth, enum. 3. p. 333. J. aculiflorus, a., Hook. fl. Bor.-Am. 2. 

 p. 190. 



Stem 15-18 inches high. Leaves with distant indistinct nodes, tapering to a sharp point. 

 Inflorescence loose and elongated. Heads few, 3 - 6-flowered. Leaflets of the calyx rather 

 obtuse. Stamens 6. Capsule oblong, sharply triangular, mucronate but somewhat obtuse, 

 a little longer than the perianth. Seeds obovoid-oblong, slightly apiculate at each end, pale 

 brown. 



New -York (Jacquemont). Among my numerous specimens of Junci collected in this 

 State, I find none that I can with confidence refer to J. pelocarpus of Meyer. The detailed 

 description given above is drawn from two specimens presented to me by Mr. Tuckerman : 

 one of them a Vermont plant, which he compared with an authentic specimen of Meyer's in 

 Sir William Hooker's herbarium ; the other a specimen of J. acutiflorus, /3., Hook. (/. c), 

 which Mr. Tuckerman obtained from Sir William himself, and which that distinguished 

 botanist regards as identical with J. pelocaryus. 



8. Juncus Conradi, Tuckerm. ( mst.). Conrad's Rush. 



Stem erect, leafy ; leaves erect, compressed, slightly nodose ; inflorescence terminal, de- 

 compound, divaricate ; flowers solitary ; leaflets of the perianth lanceolate-acute, shorter than 

 the oblong acuminate-rostrate capsule. — J. viviparus, Conrad in jour. acad. Phil. 5. p. . . . 



Annual. Stems usually cespitose, 6-10 inches high, slender, tough. Leaves few, 2-4 

 inches long, with slight transverse partitions. Inflorescence spreading ; the branches slender. 

 Involucral leaves short. Flowers often abortive, or viviparous ; the perianth of a reddish 

 brown color. Stamens 6. Style short : stigmas very long. Capsule one-celled ; the placenta? 

 parietal, very narrow. Seeds ovoid, without appendages. 



Borders of ponds, in sandy soil. Long Island. Fl. July - August. This well-marked 

 species is very abundant in the pine region of New-Jersey, and has also been found by Mr. 

 Tuckerman in Massachusetts and on the White Mountains.
