45 Small: Studies in 



panulate ; tube 3.5-4 mm. high : calices yellow, glabrous, 5 mm. 

 long, contracted into a stipe-like base ; segments cuneate-spatu- 

 late, rounded at the apex, concave, the 3 inner narrower than the 

 three outer : filaments villous below the middle : achenes 3-angled, 

 glabrous. 



In alpine regions, northern California. Summer. 



Under the name Eriogonum Tolmianum* Prof. Greene refers 

 to this plant as a " neat and pretty alpine species," and this it is. 

 However, the species does not represent Hooker's E. Tolmianum, 

 and may be distinguished from it as well as from all its relatives 

 in the umbellata group by the long, solitary pedicel which is sub- 

 tended by a whorl of several bracts. 



The type specimens were found by Prof. Greene on the Scott 

 Mountains, Siskiyou County, California, August 22, 1876. Alti- 

 tude about 2,500 meters. 



Eriogonum vineum. 



Perennial from a stout tap root, closely white-tomentose to the 

 flowers. Stems branching; branches tufted, clothed with the 

 persistent leaves or leaf-bases : leaves crowded ; blades suborbicular 

 or broadly oval, 5-8 mm. long, obtuse or rounded at the apex, 

 abruptly narrowed or truncate at the base ; petioles as long as the 

 blades or shorter : scapes erect, 2-8 cm. long, simple : bracts lan- 

 ceolate to ovate, united at the base : involucres 4-6 in terminal 

 heads, vase-shaped, 4.5-5.5 mm. high, angled, constricted near the 

 top; segments ovate, %-% as long as the tube, the tips recurved : 

 calices vinous-red or cream-colored tinged with vinous-red, finally 

 5-6 mm. long, glabrous ; segments very unequal, the 3 outer 

 oval, cordate at the base, the 3 inner spatulate, more or less crisped : 

 filaments villous at the base : achenes glabrous, 3-angled, 4 mm. 

 long ; base acute ; angles margined at the apex. 



In the mountains, Oregon and California. Spring and sum- 

 mer. 1550-2500 meters. 



Eriogonum ovahfolium together with several species has been 

 unfortunate at the hands of most of the later authors in being made 

 a group instead of a natural species. The present species is a con- 

 spicuous plant on account of the velvety white-tomentose foliage 

 and the large heads of vinous-red flowers. Besides the peculiar 

 color distinctions, the vase-shaped involucres and the large calices 

 readily separate the species from E. ovahfolium.
