516 WlEGAND : JUNCUS TENUIS WlLLD. 



subulate, acute, midrib green, margins moderately scarious : 

 stamens two thirds length of the perianth, anthers oblong-linear, 

 slightly exceeding the filament : capsule oval-oblong, obtuse, 

 scarcely apiculate, nearly equaling the perianth ; placentae meet- 

 ing at the axis : seeds oblong or ovate, irregularly curved, apicu- 

 late at each end (.28-37 x .14-. 1 7 mm.), with about 12-14 rows 

 of transversely oblong shallow areoles. 



Dry soil, Massachusetts to North Carolina along the coast 

 Specimens examined : 



Massachusetts: Medford (Boott, 1872); Winchester (G. P. 

 Huntington, 1879). 



Rhode Island : (Olney). 



Pennsylvania : Lancaster (Porter and Leidy, June. Bor. Am. 

 Engelm. no. 23, 1866). 



Delaware: New Castle Co. (W. M. Canby, 1874). 



New York : Pine Plains (L. H. Hoysradt, 1878). 



In general appearance J. secundiis is very distinct. It is espe- 

 cially characterized by the slender culm bases, membranous 

 auricles, tufted leaves, short bracts, small secund flowers, scarcely 

 spreading perianth, long anthers and placentae meeting at the 

 axis. It seems to be confined to the Atlantic coast, while the 

 Mississippi Vally forms heretofore ascribed to it are to be referred 

 to a distinct species, J. interior. 



* 5 . Juncus interior sp. nov. 



Tall and rather stout (5-10 dm. high), light green : stem 

 erect, nearly terete, coarsely grooved : leaves several, about one 

 third length of culm, blades narrow (1-1.25 mm. wide), flat or in- 

 volute : sheaths nearly all blade-bearing, large and loose, margin 

 and short rounded auricles membranous, often slightly yellowish : 

 inflorescence large and open, very many flowered, 3-10 cm. long, 

 branches conspicuously ascending : flowers distant and scattered, 

 not secund, pale stramineous : bracts commonly two, exceeding 

 the inflorescence : bracteoles acuminate : perianth 3-4 mm. long, 

 its parts nearly equal, broadly subulate, very acute, scarious mar- 

 gin narrow, extending on the inner to the tip, all appressed or 

 erect : stamens one half the length of the perianth : anthers short- 

 oblong, much shorter than the filaments : styles very short : cap- 

 sule oblong or rarely ovate-oblong, obtuse, barely apiculate, 

 equaling the perianth ; placentae not quite meeting at the axis ex- 

 cept at the ends : seeds oblong, rather small (.35-.50 X ♦I4~I7 

 mm.), apiculate at both ends, shallowly areolate.
