Southern California ; frequent in marshes in the Coast Ranges from Santa Clara Valley {Peck- 

 A«»2?to sL D -o Cooper. Resembling /. amtus of the Old World, which has a shorter and 

 more spreadin-^ «n ^"d bracts, a triangular and acute capsule, and usually 



more distinJuy Culate seeds. The tough scapes are split by the Indians and used in binding 

 together their baskets. 



9 J Cooperi En<K^Jm. A similar species : outer perianth-segments subulate- 

 lanJeolate, acute, the inner ovate-lanceolate and mucronate, 3 hues long : anthers ^ 

 lines long : capsule ovate, acute, slightly longer than the perianth greenish : seeds 

 larger, with broad white appendages, more irregularly ribbed. — irans. bt. Louis

Known only from a single imperfect specimen, collected '-^.t C-"i.P Cady on the Mohave River 

 (J. G. Cooper): scape nea.ly 2 feet high, with a greenish panicle 3 inches long. 

 ^ ^ Flowers solitary, hexanclrous (triandrous in n. 7): scapes slender : sheaths 

 leafless except in Nos. 5 and 10: spathes usually very much exceeduuj the in- 

 florescence. 

 «. Flowers in compound panicles, large (2 lines long or more): capsule ohlong- 



ovate. 

 ■ 3 J Leseurii Boland. Scapes often stout, but soft and sometimes hollow, 1 

 to 3 feet high, from a stout creeping rhizome : panicle lax and spreading, many- 

 flowered, the flowers somewhat secund on the branches : perianth-segment^ 2^ to 6 

 lines loner, lanceolate, acuminate, with brown margins, the inner ones a little sliorter 

 and obtusish : anthers much longer than the fllaments : capsule brown, oblong-oyate, 

 acute, not beaked, equalling or a little shorter than the perianth :see.ls ovate,_ obtuse, 

 scarcely apiculate, smoothish or somewhat reticulate. — Proc. Calif. Acad. n. 1/9 ;

 thc^tmf but with the panicle small and compact, was collected in flower at Klatsop, Oregon, 

 on the se'a-shore in drifting sand, by Prof. Wood. 



4 J Balticus Dethard. Distinguished from the last by its rather more rigid 

 scapes (usually 1 or 2 feet high), smaller flowers (H to 21 lines long), the capsule 

 more acutely angled (in our forms) and mucronate or beaked, and the seeds more 

 distinctly reticulated. -Eeicheub. Icon. Fl. Germ. ix. t. 411 ; Engelm. 1. c. 441

 the scathes (G to 12 inclies high) somewhat flattened, and the sheaths frequently lesit-
