rounded above; anthers 2 lines long: capsule long-stipitate, oblong, 
attenuate upward; cells about 6-seeded. — Klickitat County, Wash- 
ington Territory; Joseph Howell, June, 1879. 
Lirium Grayi. See page 256. Since the preceding pages were 
in type, flowering specimens of this species have come to hand, 
collected (June 20) on the sides of Roan Mountain by Dr. Gray and 
Prof. C. S$. Sargent. These show a nearer approach in some respects 
to L. Canadense, the leaves being narrower than in the original speci- 
mens and the flowers (1 to 8) are somewhat nodding, but still less 
decidedly pendent when open than is the usual habit of Z. Canadense. 
The flowers are smaller (1} to 2 inches long), but broader at base, 
the segments broader in proportion to the length and more abruptly con- 
tracted into the terminal cusp, deeply colored and but slightly spread- 
ing. The root is similar to that of Z. Canadense and L. superbum. 
LuzuLa Carouine. Very slightly villous: stem a foot high or 
more, with broad flat leaves and a foliaceous bract exceeding the 
diffuse and lax cyme: flowers solitary on slender pedicels: anthers 
linear, about equalling the filaments: capsule with narrowly ovate 
valves, 14 lines long, a little longer than the light-brown perianth: 
seed brown, subglobose, with a narrow whitish somewhat wing-like 
rhaphe.— On Grandfather Mountain in North Carolina; Gray and 
Carey, July, 1841. Differing from Z. pilosa in its smoothness, the 
conspicuous bract, narrower capsule, and smaller seed without the 
prominent terminal twisted appendage. 
Luzuita pivaricaTa. Usually low (6 inches high or less), and 
resembling ZL. spadicea, var. parviflora, except that the cyme is 
broadly diffuse with divaricately spreading branches and_ pedicels, 
and the seed is light-colored with a small appendage at base. — In 
the Sierra Nevada, mostly alpine, from above Mono Lake to Sierra 
County; W. H. Brewer (n. 1794, 2069, 2334), Rev. E. L. Greene, 
and J. G. Lemmon. 
Juncus RoBustus. Terete scape and leaves 2 to 5 feet high, very 
stout, rigid and pungent; the sheathing bases narrowed gradually 
above: lateral panicle compound with very unequal branches, erect 
and strict, usually 3 to 6 inches long and about equalling the scape ; 
spathes and bracts long-acuminate, equalling or exceeding the flowers: 
clusters 2—4-flowered: outer perianth-segments broadly lanceolate, 
acute, the inner obovate and deeply emarginate, a line long: capsule 
subglobose, narrowed below, rounded at the summit, apiculate, brown, 
nearly 2 lines long: seeds acute at each end or slightly caudate, very 
finely ribbed, about a half-line long. — J. acutus, Engelm. Proc. St.
