riTTONIA. 



^ 



seeds ovate, apiciilate at each end; neither ribbed nor even 

 regularly striate, but marked with transversely elongated 

 quadrate reticulations. 



Low moist places in fields near Suisun, California, May, 

 1S90, associated with Piliilaria, a terrestrial CalUiriche, and 

 near the habitat of Howellia limosa. Yery unlike our other 

 small annual rushes as to its perianth and seeds. 



SisiTJNCHiuM Elmeri. Scape 6 to 10 inches high, very 

 slender, less than a line wide, bearing a single spathe : leaves 

 only 2 or 3 inches long, narrow, thin and delicate, not firmly 

 erect : bracts of the spathe slightly unequal, rather obtuse, 

 as long as the pedicels : ovary obovate. glabrous : perianth 

 I inch broad, yellow with purple lines, the segments acute. 



Lake Eleanor, in the Sierra Nevada, 28 June, 1889, Elmer 

 Drew. Very unlike the stout glaucous S. 

 western California, a plant which keeps neir tirj seashore 

 and IS not likely to occur in the mountains. Doubtless the 

 yellow-flowered species attributed to Plumas County in the 

 ' Jiotany of California " will prove to be S. Elmeri. The true 

 6. Californicum, without becoming discolored in drying, 

 ieave^ its impress on the herbarium sheets in a very dark 

 purple : a property not possessed by the new species,
