Heads 30-40- 

 flowcred; stems 

 not rugosely 



roughened. 10. J. torreyi. 

 Heads 6-10- 



flowered; stems 

 rugosely 



roughened. 11. J. rugulosus. 



Leaves grass-like, not 



septate. 12. J. macrophyllus. 



1. J. bufonius L. Stems usually branching from the base, 5-25 

 cm. high, with fibrous roots; leaves 0.5 mm. wide or less; flowers 

 mostly solitary and remote upon the spreading branches; perianth 

 segments lanceolate, greenish, with scarious margins, 4-6 mm. 

 long; stamens 6, sometimes 3, 2-3 mm. long; anthers shorter than 

 the filaments; capsule oblong, obtuse, shorter than the perianth. 



Common in the valleys and mountains in moist ground. 



2. J. effusus L. Perennial from creeping rootstocks, forming 

 dense clumps, 5-8 dm. high; stems stout, terete, leafless; panicle 

 lateral, compact, many-flowered; perianth, brown, 2 mm. long; 

 stamens 3; capsule clavate-oblong obtuse or retuse. 



Not collected within our limits, but found in San Bernardino 

 Valley Parish, also in the San Bernardino Mountains (Abrams) 

 and San Ysabel {Abrams). 



3. J. textilis Buchn. Stems rigid, stout, 1.5-2.5 m. high, leaf- 

 less, from a stout creeping rhizome; panicle lax and widely spreading, 

 6-12 cm. long; perianth segments 5-6 mm. long, lanceolate, acumi- 

 nate, with brown margins; anthers much longer than the filaments; 

 capsule oblong-ovate, acute, beakless, about equaling the perianth. 



Occasional along streams in foothill canyons. What seems to be 

 the same has been collected by the author along New River near 

 Long Beach. 



4. J. patens Meyer. Stems rather soft, 0.5-1 m. high; inner 

 sheaths tipped with a short awn; panicle rather open, about 4 cm. 

 long; perianth segments 3 mm. long, often brownish, spreading in 

 fruit; stamens 6; capsule subglobose, slightly angled, obtuse, apicu- 

 late, equaling or a little shorter than the perianth. 



Canyons of the Santa Monica Mountains, Hasse. 



5. J. balticus Willd. Stems rigid, rather slender, leafless, 3-4 

 dm. high; panicle 2-4 cm. long; perianth segments lanceolate, acute, 

 4-5 mm. long, brownish; capsule rather acutely angled, beaked; 

 seeds distinctly reticulate. 



Frequent along streams and in low ground generally throughout 

 our range. 



6. J. mexicanus Willd. Closely resembling the last, but more 

 slender, 12-24 cm. high; stems somewhat flattened, sheaths fre- 

 quently leaf-bearing; panicles about 2 cm. long, loosely few-flowered; 

 perianth segments 4-5 mm. long, lanceolate, greenish or slightly 

 tinged with brown. (/. compressus H. B. K.) 



Habitat similar to the last, and apparently more common.
