7. S. Kingii, Boland. 1. c. Culms tufted, 6 to 20 inches high, covered below 

 by the remains of numerous sheaths, slender, smooth, with but two nodes near the

 sparsely pubescent, with a few longer hairs at tip which is very minutely 2-toothed ; 

 awn 6 lines long, bent below the middle, scabrous and very persistent ; upper palet 

 equalling the lower and hairy at apex : anthers bearded at tip. 



Mount Dana, at 7,000 to 12,000 feet altitude, Bolander. This exceedingly neat and delicate 

 species is named in honor of Mr. Clarence King.

 coarse hairs ; upper palet nearly equal ; awn 6 to 9 lines long, flexuosely geniculate

 smooth except the pubescent nodes: radical leaves 12 to 18 inches long, those of 

 the culm (four or five) much shorter, all glaucous, involute at least at the long atten- 

 uate apex, the lower 3 to 4 lines wide at base, mostly smooth below, scabrous above 

 and on the margins ; ligule minute ; sheaths loose, shorter than the internodes, 

 striate, smooth, slightly bearded at the throat : panicle 5 to 10 inches long, narrow 

 and spike-like, interrupted below, nearly white and lustrous, the axis puberulent 

 with an incomplete pilose ring at the nodes ; rays crowded and fasciculate, more or 

 less united below, 1 - few-flowered : glurnes nearly equal, about 9 lines long, acumi- 

 nately bristle-pointed, memhranaceous-hyaline, the lower 3-, the upper more or less 

 5-nerved at base : floret 5 lines long with a short one-sided white-hairy callus ; lower 

 palet herbaceo-chartaceous, distinctly 3-nerved, sparsely pubescent throughout, the 

 divisions of the 2-cleft tip nearly a line long ; upper palet similar ; awn inserted be- 

 low the tip of the palet, 12 to 15 lines long, tortuous, slightly bent above the mid-

Blue Canon, Sierra Nevada, Bolander. The stout culms, as large as a goosequill, are from a 

 large tortuous almost woody rhizome, which is hairy, as are the rootlets proceeding from it. The 

 large and lustrous panicles are strikingly handsome. 



10. S. coronata. Culm 4 to 6 feet high, 3 or 4 lines thick at base, where it is 

 clothed with the remains of old sheaths : lower culm leaves about 3 feet long, 4 to 6 

 lines wide at base, gradually attenuate to a long involute point, the uppermost about 

 6 inches long, almost filiform and rigid, all slightly scabrous on both surfaces and
