 AN UNDESCRIBED SCIRPUS FROM CALIFORNIA 



By N. L. Brixton 



y Scirpus Congdoni sp. nov. 



Perennial by short stout rootstocks. Culms slender, erect, 

 smooth, somewhat trigonous, 4-5 dm. high, leaf-bearing below 

 the iriiddle. Leaves linear, smooth, acuminate, 5-6 mm. wide, 

 the lower ones 1.5-2 dm. long, the upper shorter; involucral leaf 

 similar to the others, 3-7 cm. long; umbel more or less compound, 

 its principal rays 3-6, very slender, 8 cm. long or less; spikelets 

 sessile, capitate at the ends of the rays and raylets, several- 

 flowered, the heads 7-10 mm. in diameter; scales brown, ovate 

 to ovate-lanceolate, rather abruptly acuminate; style 3-cleft; 

 achene pale, trigonous, about i mm. long, its short subulate beak 

 about 0.2 mm. long; bristles filiforme, curled, only shghtly 

 roughened, rather longer than the achene. 



Sierra Nevada, California. Type, preserved in the Dudley 

 Herbarium of Stanford University, collected by J. W. Congdon 

 on the Upper San Joaquin, Madera County, August 18, 1895. 



Professor Fernald obligingly informs me that the plant re- 

 corded in Dr. Watson's Botany of California as 5. atrovirens, 

 collected by Mrs. Austin in Plumas County, is referable to the 

 species here described; the Hall and Chandler specimen No. 217 

 from Pine Ridge, Fresno County, is the same. 



Record may here be made that the Oregon plant collected by 

 Howell and referred to 5. atrovirens in Botany of California is 

 S. pallidiis (Britton) Fernald, as now determined by Professor 

 Fernald; the Washington sedges recorded by Professor Piper 

 as 5. atrovirens are also S. pallidus. 



These studies indicate that all records of 5. atrovirens from the 

 Pacific States are erroneous.
