sensim examen ; capitulis multi-(15-25)floris paucis glomeratis 
. paniculatus : caule bi-tripedali ; vaginis foliisque ut in a. ; capitulis minoribus pauci-(8-12)floris com- 
posite seated

California, from the sea-coast into the Sierras ; var. a. near the coast, from Monterey, Haenke, Brewer, to San 
Francisco, Bolander, Kell Hb. norm. 96, and to ieack Bolander ; var. B. also in the lowlands, Napa Valley, 
igelow, San Francisco, Bolander, Kellogg, Hb. norm. 97, and in the mountains, Bolander ; var. y. in the higher moun- 
tains, about the “ Big Tree Grove,” Hillebrand, Bolander, and especially in the upper Tuolumne Valley, Brewer, Cal. 
St. Surv. 2339, 1709 and 1760, Bleue, 5062, Hb. norm. 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 markings of their seeds, whatever the height of the stem, width of the leaves, or [485] 
nature of the inflorescence may be. — Flowers 2-2} lines long ; sepals gage and either obtuse, or, usually, 
acute or acuminate and even with subulate tips, the inner ones as long as the outer ones, but often more obtusish; 
anthers about 1 line (in a large-flowered specimen of var. y. even ik ‘a , always much longer than the filament ; 
capsule long mucronate, scarcely exceeding the sepals, incthuletaty 3-celled, ny the projection of the placente ; seeds 
0.31-0.33 line long, their length being equal to 2 diameters ; 8 or 9 ribs visible ; reticulation close but distinct; are 
smooth or marked with one or two delicate perpendicular lines, and thus similar to the seeds of J. scirpoides, which, 
however, have fewer ribs. — E. Meyer (I. c.) describes the plant very correctly, but suspecting that the flattened 
appearance of stem and might be owing to undue pressure in drying, places it with doubt with J. Rostkovit, 
from — it is yaad differe 
. has leaves 1-2 lines wide, as long or longer than the stem ; heads xpd nig 5 lines in diameter, 
tN + or rBi ina ey or sometimes as many as 6 or 8 in a short panicle. — Leaves of var. 8. 2 lines wide, shorter 
than the tall stem ; panicle loose-flowered, somewhat erect, sometimes 6 inches in faaile Some of the mountain 
forms collected by Mr. Bolander (Yosemite Valley, Cal. St. Surv. 6036, and especially “alpine meadows,” 6006, which 
is only a foot high) have smaller flowers 14-1? lines long, and seem to approach closely to J. oxymeris. — Under Hb. 
norm. 97 two forms have been inadvertently mixed, one the real var. paniculatus, and the other a tall (2-3 feet high) 
several-headed form of var. glomeratus. — Var. y. is a small mountain form, which with its dark heads, large flowers, 
and long protruding stigmas, resembles so nearly the smaller forms of J. falcatus, that a close examination only will 
distinguish them ; leaves }-} line wide; heads 4-5 lines in diameter, single or two together. 
51. J. CHLOROCEPHALUS, n. sp.: caulibus (pedalibus sesquipedalibus) e rhizomate brevi repente czespitosis 
erectis et foliis compressis ; ougttatis caueas 15-25) floris singulis seu paucis glomeratis spatham membranaceam sub- 
equantibus ; floribus magnis conspicue pedicellatis pallidis; sepalis oblon i i issi 
interioribus mucronatis equalibus seu interioribus paulo longioribus stamina vix excedentibus ; antheris longe-lineari- 
bus filamento multo longioribus ; stylo jena ovato pluries longiore exserto ; stigmata equante vel iis longiore ; cap- 
sula ovata obtusa mucronata uniloculari sepalis breviore ; seminibus ovatis utrumque apiculatis —— 
In the higher mountains of California, Hillebrand, Cal. St. Surv. 2338 ; dry places on peaks nea 
Dana, 10,000 ft. high, Brewer, Cal. St. Surv. 1804; along the rapid current of streamlets in Yosemite “Valley [486] 
4,000 feet high, itetdier. Cal. St. Surv. 6033, Hb. norm. 99; mountains near Carson City, Nevada, C. L. And 
son. — Allied to the last, but readily distinguished by its pale flower heads, which look more like those of some eyper- 
aceous plant, its broad and obtuse sepals, small ovary, very long style, shorter stigmata, and very short obtuse capsule. 
— The specimens before me are from 10 to 17 inches high, pale green, with the auriculate sheaths often rose purple ; 
leaves 4-1 line wide, like the stem compressed, but not See shorter than the stem; 1-3 heads, 6-7 lines in 
diameter ; flowers 24 lines long, pale or whitish-green, shining ; sepals very obtuse, often mucronate or cuspidate, 
with membranaceous margins ; stamens scarcely sate: and sometimes even a little longer, than sepals; 
anthers twice to four times as long as filament, much exceeding the ovary; style often twice as long as the ovary ; 
i in the only fruiting specimen which I could examine, much shorter than the sepals ; seeds (immature) very 
ilar to of the last species, 0.32 line long and more than half as wide, 7-8 ribs visible on the side, reticulation 
diiian, but, as yet at least, no transverse lineolation visible. 
During the two years which have passed since the first part of this paper, pp. 424-458, was 
published, the attention of many botanical friends has been directed to our Junci, and their exertions 
have enabled me to add several new species to the foregoing list, complete the history of others, and
