 STIPA SPEC 1 OS A Trin. and Rupr. Stipaceae, 45. 



Plant perennial, with cespitose, bulbous base, and coarse woolly roots. 



Culms erect, simple, terete, smooth or slightly hispid, 1 to 2 feet high. 



Leaves from the base numerous, with mostly scarious, reddish sheaths, smooth or 

 velvety-pubescent and filiform-convolute, smooth or slightly scabrous blades, 5 to 12 

 inches long. Leaves of the culm usually 3 ; sheaths rather loose, upper one vaginate and 

 inclosing the lower part of the panicle, striate, scabrous, nearly as long as the inter- 

 nodes; blades slender-pointed, less convolute and shorter than those of the radical 

 tuft; ligule a short fimbriate membrane. 



Inflorescence -a narrow, erect, strict panicle, 3 to 7 inches long, included at first; 

 branches mostly in twos or threes, unequal, the shorter spikelet-bearing to the base, the 

 longer bearing about G pedicellate spikelets beyond the lowest third. 



Spikelets spindle-shaped, 1-flowered, 7 to 8 lines long; empty glumes lanceolate, 

 slender-pointed, often lacerate near the apex, membranaceous above, smooth, 7 to 8 

 lines long; first glume 3-nerved; second gluine 5-nerved ; stipe curved, slender-pointed, 

 bearded, § to 1 line long; floret narrowly spindle-shaped, 3i lines long and about J line 

 thick; floral glume chartaceous, clothed with rather stiff pubescence, which is slightly 

 longer and scarcely tufted at the apex, obscurely 5-nerved; awn articulated, often 

 deciduous, sharply bent at the middle, twisted and copiously plumose below, smooth, 

 slender, and dark-colored above, 2 inches long; palet oblong, obtuse, boat-shaped, 

 pubescent between the 2 nerves, 2£ lines long; anthers exserted, naked; lodicules 

 slender, a line long; grain spindle-shaped, yellow, with a white line on the ventral side, 

 opaque, 3 lines long. 



Plate XIV; a, spikelet partly dissected, enlarged twice. 



California, extending east to Arizona and southern Utah. Throughout the same 

 range is found 8. speciosa, var. clirysophylla, which may include several variable forms, 

 usually referred to S. chrysophylla. It is generally only 6 to 10 inches high, with 

 a panicle 2 to 4 inches long, the parts of the spikelet varying to slightly smaller than 

 those of the species.
