JuNcus LoNUisTYLis (u. sp.) : culmo erecto simplici compresso foliato ; foliis planis gramineis ; 

 capitulis paucis 4-G-floris in panicula suh-simplici dispositis ; sepalis lanceolatis mucronatis 

 capsula ohovato-oblongo ohtusa mucronata paullo longioribus ; geminibus oblongis utrinque 

 acutis ecaudatis- Near the Copper Mines, New Mexico, June ; JBigeloio. (No. 1924, WrigJd,) 

 Culms from a rather stout root-stock, 12-18 inches high, slender, distinctly compressed. Leaves 

 flaccid, 1-1^ line wide, obscurely nerved ; the radical ones 6-8 inches long, those of the culm 

 (2-3 in number) shorter. Heads 4-8 in a contracted or oblong panicle, the bracts at the base 

 ovate, scarious, about as long as the sepals. Stamens 6. Style more than half as long as the 

 ovary. Capsule usually about one-fifth shorter than the sepals. A very distinct species. J. 

 marginatus, to which it is nearest related, differs in the usually much more numerous heads, 

 triandrous flowers, short style, obtuse inner sepals and subglobose capsule. No. 857 of Fend- 

 ler's New Mexican collection seems to be a variety of this species, with only two or three closely 

 approximated heads,
