﻿North American Polygonaceae. 47 



pink with a reddish rib, unequal, the 3 outer broadly oblong, the 

 3 inner cuneate-spatulate : filaments glabrous: achenes 3-angled, 

 glabrous. 



In dry soil, southern California. Spring and summer. 



A dwarf species related to Eriogonum marifolinm y the foilage of 

 the two species being quite similar. The plants of E. polypodum 

 that have come to my notice produce numerous scapes, each of 

 which is topped by a head or aconjested umbel instead of the open 

 more or less straggly umbel characteristic of E. marifolium. The 

 broadly-oblong outer calyx-segments and the cuneate-spatulate 

 inner segments together with the glabrous filaments all serve to 

 distinguish the species here described as new from E. marifolium U 



The original specimens were collected at Long Meadow, Tulare 

 County, California, June 7-14, 1888, by Dr. Edward Palmer at an 

 altitude of 2,200-2,800 meters. Number 204. 



«/ Eriogonum Harfordii. 



Perennial by horizontal rootstocks. Foliage floccose-tomen- 



tose : leaves basal ; blades spatulate, 2-6 cm. long, obtuse, crispen, 



densely white-tomentose beneath, floccose or glabrate above; 



petioles longer than the blades : scapes erect, 8-10 dm. tall, simple 



below, forking above, stout: bracts somewhat foliaceous below, 



scale-like above, involucres sessile, solitary or several at the ends 



of the ultimate branchlets, turbinate-campanulate, 5 mm. long, 



fluted; segments triangular- ovate, obtuse: calices white or pink, 



3.5-4 mm. long, villous at the base; segments unequal, the 3 



outer orbicular-oval, the 3 inner cuneate, longer than the outer, all 



erose or crisped : filaments villous near the base : achenes sharply 

 3-angled. 



On dry hillsides in valleys, Mendocina County, California. 

 Summer. 



Near Eriogonum affine but more robust and of stricter 

 habit. The leaf-blades are broadest above the middle, the in- 

 volucres twice the size of those of E. affine and the calices pubes- 

 cent at the base as contrasted with the glabrous calices of its 

 northern relative. 



Named for Mr. W. G. W. Harford, who collected the speci- 

 mens in company with Dr. A. Kellogg, in Long Valley, Mendo- 

 cina County, California. Number 874. 



* Eriogonum minimum.
