256 JUNCACEAE 



scarious; segments 2 lines long, obtuse or acute; style exserted; capsule shorter 

 than the perianth. 



Sierra Nevada, 6400 to 8400 feet, from Nevada Co. to Mariposa Co.

 "higher mts. of California" (= Sierra Nevada), Hillebrand 2338. 



26. J. dubius Engelm. (Fig. 44a-c.) Stems very slender, compressed, 2 to 

 4 feet high, from stout horizontal rootstocks; leaves narrow (1 line broad) but 

 rigid, % to nearly as long as the stems, coarsely septate ; panicle compound, 

 diffuse, 3 to 12 inches long; heads 6 to 20-flowered, numerous; perianth brown 

 or brownish, l l / 2 to 2 lines long, the segments lanceolate, acuminate; anthers 

 elongated, rather exceeding the filaments; capsule narrowly oblong, acuminate, 

 slightly longer than the perianth ; seeds abruptly apiculate at each end, reticu- 

 late, brownish. 



Mariposa Co. to Sierra Co. The leaves suggest diminutive bamboo fishing rods. 



Locs. Yosemite Valley, Jepson lOOa; Sierra Valley, Jepson 80.43. A local and little 

 known species, known to us in typical form only from Mariposa. and Sierra cos. but probably 

 occurring elsewhere in the Sierra Nevada, especially southward. It is similar in aspect to 

 J. oxymeris but the leaves are narrow and compressed, very strongly or even coarsely septate, 

 and the sheaths are ligulate. The following do not have the. leaves coarsely septate nor as 

 rigid as in the type, but agree otherwise: Heteh-Hetchy, Jepson 3416; Middle Camp, 

 Tuolumne Co., A. L. Grant 4 (det. Coville) ; Yankee Hill, Columbia, Jepson 6453. 



Eef. JUNCUS DUBIUS Engelm. Trans. St. Louis Acad. 2:459 (1868), type loc. Mariposa 

 Big Trees, Bolander 6032. 



27. J. rugulosus Engelm. (Fig. 44d, e.) Very closely allied in habit and 

 character to J. dubius; stems stouter, l 1 /^ to 3 feet high, sharply and minutely 

 transverse-rugulose ; leaves strongly septate, attenuate into a flagellate-filiform 

 tip; panicle 4 to 9 inches long; heads small, 4 to 6-flowered; perianth li<4 to iy 2 

 lines long, its segments oblong-lanceolate, acuminate ; filaments 1% to 2 times 

 as long as the anthers; capsule oblong and acuminate, or lanceolate or broadly 

 subulate, prismatically and sharply triangular, slightly exceeding the perianth. 



Damp meadow land or marshes, southern Mohave Desert through the valleys 

 of cismontane Southern California to San Diego. This differs from J. dubius, 

 aside from the wrinkled epidermis, only in the relative length of the anthers 

 which is not an absolute character.

Eef. JUNCUS RUGULOSUS Engelm. Bot. Gaz. 6:224 (1881), type loc. south foot of San 

 Bernardino Mts., W. G. Wright. 



28. J. oxymeris Engelm. Stems 1 to 2 feet high, compressed, somewhat 

 angled, erect, from an elongated horizontal rootstock, often stolonif erous ; leaves 

 broad and flat, equitant (l 1 /^ or) 2 to 3 lines wide, ligules not present, transverse 

 partitions not conspicuous; involucral bract short; heads 5 to 10-flowered, set 

 singly in a loose panicle ; perianth segments brownish, linear-lanceolate, subulate, 

 of equal length or the interior slightly longer; anthers 6, longer than the fila- 

 ments ; styles long exserted ; capsule long attenuate, exceeding the perianth ; seeds 

 small, obovate, apiculate, light brown and finely reticulate. 



Moist valleys and mountain flats, Coast Ranges and Sierra Nevada, 50 to 6000 

 feet. North to Oregon.
