484: TRANS. OF THE ACAD. OP SCIENCE. 



This species is intermediate between /. xiphioides, var. 

 auratus, the paniculate form of J. p/ueocephcdus and J. du- 

 bius ; from the two first it is distinguished by the sharp 

 pointed sepals and their proportion, and the almost subulate 

 capsule, which is similar to that of J. nodosus, from the first 

 also by the long anthers, from the last by the flat leaves, and 

 from both these by the sculpture of the seed. Sheaths of the 

 leaves with or without auricular appendages, leaves 1-2 j 

 lines wide ; panicle 4-6 inches long ; flowers ljj-2 lines long, 

 greenish straw-colored or sometimes reddish towards the 

 tip ; seeds 0.22-0.24 line long, with the ribs (7-9 visible on 

 the side) slightly crenulate but the areas smooth.

 apice capitulum singulum paucave multiflora sen rarissime 

 plura minora paniculata gerentibus ; foliis compressis basi

Var. a. glomeratics: rhizomate longe repente, caule spitha- 

 raeo sesquipedali ; vaginis sine auriculis in folia latiora sensim 

 excurrentibus; capitulis multi-( 15-25 )floris paucis glome- 

 ratis. 



Var. P. paniculatus: caule bi-tripedali; vaginis foliisque 

 ut in a; capitulis minoribus pauci-(8-12)floris composite pa- 

 niculatis. 



Var. y. gracilis : caespitosus caule digitali spithameo; va- 

 ginis auriculatis; foliis angustis seu angustissimis; capitulis 

 multi-(15-20)floris saapius singulis. 



California, from the sea-coast into the Sierras; var. a near 

 the coast, from Monterey, JIaenke, Brewer, to San Francisco, 

 Bolander, Kellogg, Hb. n. 96, and to Mendocino, Bolander ; 

 var. 13 also in the lowlands, Napa Valley, Bigelow, San Fran- 

 cisco, Bolander, Kellogg, lib. n. 97, and in the mountains, 

 Bolander ; var. y in the higher mountains, about the " Big 

 Tree Grove," Ilillebrand, Bolander, and especially in the 

 upper Tuolumne Valley, Brewer, Cal. St. Surv. 2339, 1709 & 

 1760, Bolander, 5062, Hb. n. 98, ami Mono Pass, the same,

 recognized by their deep brown heads, large flowers, broad 

 sepals, large conspicuous anthers, long style, and by the mark- 

 ings of their seeds, whatever the height of the stem, width of
