TRANS. OF THE ACAD. OF SCIENCE. 
This species is intermediate between J. xiphioides , var. 
auratus , the paniculate form of J. phceocephalus and J. du - 
bins; 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$ 
lines wide ; panicle 4-6 inches long; flowers If-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 ajreae smooth. 
50. J. pmiocephalus, n. sp.: caulibus erectis compressis 
apice capitulum singulum paucave multiflora seu rarissime 
plura minora paniculata gerentibus ; foliis compressis basi 
auriculatis seu inappendiculatis; floribus majoribus fusco-atris 
pedicellatis; sepalis lanceolato-ovatis aequilongis omnibus 
acuminatis acutis vel cuspidatis seu interioribus obtusatis sta¬ 
mina 6 paulo superantibus capsulam obtusam seu acutam 
mucronatam subunilocularem aequantibus seu ea paulo bre- 
vioribus; antheris late linearibus filamento bis terve longi- 
oribus; ovario lanceolato in stylum sequilongum attenuato, 
stigmatibus elongatis exsertis; seminibus ovatis utrumque 
apiculatis areis sublaevibus reticulatis.— J, Bostkovii? Meyer 
in Rel. Haenk. 1, 142. 
Var. a . glomeratus: rhizomate longe repente, caule spitha- 
meo 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 saepius singulis. 
California, from the sea-coast into the Sierras; var. a near 
the coast, from Monterey, Haenke , Brewer , to San Francisco, 
Bolander , Kellogg, Hb. n. 96, and to Mendocino, JBolctnder ; 
var. (3 also in the lowlands, Napa Valley, Bigelow , SamFran- 
cisco, Bolander , Kellogg , Hb. n. 97, and in the mountains, 
Bolander ; var. y in the higher mountains, about the “ Big 
Tree Grove,” Hillebrand , Bolander , and especially in the 
upper Tuolumne Valley, Brewer , Cal. St. Surv. 2389, 1709 & 
1760, Bolander , 5062, Hb. n. 98, and Mono Pass, the same , 
6013.--All the forms of this variable species are readily 
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
