upper leaves. Calyx rose-purple, urceolate, narrowed under the spreading 

 lobes; the lobes obtuse, membranously margined, and undulate, becoming as 

 long as the tube formed by the united sepals; disk-like receptacle conspicu- 

 ous. Petals rose-pink, the slender claws exserted, blades spatulate to 

 obovate-orbicular, half as long as the claws (3 mm.), and more than twice 

 as broad (2 mm.), sinuate. Stamens in three pairs, with filaments all distinct, 

 one pair with filaments i mm. long, the next pair 2 mm., and the third 

 5 mm. ; the anthers of the two shorter pairs 3 mm. long, those of the longest 

 pair not quite 2 mm. Pods (immature) erect, linear, glabrous, tipped with a 

 broad, sessile stigma; the largest 1.5 cm. long, i mm. wide. Seeds not known. 



This delicate little plant was collected by the author 

 below timber line on the trail from East Lake to Harri- 

 son's Pass (the type locality), and by Miss Catherine E. 

 Wilson, in 1898, on the trail to Bull-frog Lake. It seems 

 to be rare. 

 sj 2. Polygonum exile, sp. no v. 



Annual, with slender, wiry stems, erect, four-ribbed, about 3 dm. high, 

 glabrous or minutely puberulent, especially near the top, with few erect, 

 virgate branches from near the base. Leaves erect, linear-lanceolate, or 

 terete from the inrolling of the margins, jointed to the ochreae, cuspidate, 

 the upper surface minutely dotted; lowest leaves 2 cm. long, diminishing 

 upwards, shorter than the internodes; ochreae with three hyaline, long-acumi- 

 nate divisions. Flowers solitary or few at the nodes, erect, sessile, or on 

 short pedicels; divisions of the perianth extending to below the middle; 

 white, pinnately veined with green or rose-colored veins, elliptical, hooded at 

 apex, 2.5 mm. long, investing the ripe seed. Stamens three, with ovate, 

 long-acuminate filaments half as long as the perianth; anthers minute. 

 Akene three-angled, rhombic in outline, acute at each end, 2.5 mm. long, 

 brown, glossy, minutely papillate; styles very short, deflexed. 



This is similar in general appearance to P. douglasit 

 Greene, but differs in having but three stamens and in the 

 erect flowers. 



Collected by the author in Kings River Canon, July 4, 

 1899. 

 w 3. Eriogonum scapigerum, sp. nov. 



Caudex branched, the divisions clothed with the dead brown bases of 

 former leaves. Leaves all radical, oblong to orbicular, 5-15 mm. long, 

 densely white-matted-tomentose on the lower surface, becoming somewhat 

 glabrate on the upper, with undulate margins, obtuse apex, and cuneate 

 base, tapering abruptly to the long petiole; petiole 3-5 cm. in length, flat, 

 with a central rib, and broadening at base for about half the length. Scapes 

 many, very slender, glabrous, 5-17 cm. high, terminated by a solitary head
