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. 



Lilium 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 3) are somewhat nodding, but still less 

 decidedly pendent when open than is the usual habit of L. 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 L. Canadense and L. superbum. 



Luzula Carolina. 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, l£ 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 L. pilosa in its smoothness, the 

 conspicuous bract, narrower capsule, and smaller seed without the 

 prominent terminal twisted appendage. 



Luzula divaricata. Usually low (6 inches high or less), and 

 resembling L. spadicea, var. parvijlora, 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.
