Juncus scirpoides compositus var. nov. 



Rootstocks, stems and leaves essentially similar to those of J. 

 scirpoides Lam. (as that species is commonly interpreted). Flowers 

 in short dense spikes, which are aggregated to the number of 

 about half a dozen in each of the numerous subglobose heads 

 about 8 mm. in diameter : sepals acute, 2 mm. long : capsules 

 beaked, about 2.5 mm. long, 



The form here proposed as a new variety has been collected by 

 several botanists, but hitherto always included \x\ J. scirpoides. It 

 was briefly described by Chapman (Fl. So. U. S. 494) in i860, and 

 a few years later by Engelmann (Trans. Acad. Sci. St. Louis 2 : 

 468, 469. 1868), who placed it as a form of his/, scirpoides 

 macrostemon macrostylas y but without giving it a name. J. scir- 

 poides normally has heads spherical and not perceptibly lobed, 

 sepals 3 mm. and capsule often 5 mm. long. I have never had 

 any difficulty in recognizing the new variety in the field, even from 

 dead specimens nearly a year old ; and in the herbarium it is as 

 easily distinguished from J. scirpoides as are J. megacephalus, 



y. bracJiycai'p 



In view of its distinctness 



(which may some time perhaps entitle it to specific rank) there can 

 be no object in letting it remain longer unnamed.

 Berrien, which are likewise in the Altamaha Grit region, and Mcin- 

 tosh, Wayne and Charlton in the flat pine-barren country, usually 

 around sand-hill ponds and bogs. Its habitat is distinctive, and 

 usually not shared by any other /uncus. It seems to flower mostly
