s near Mendocino City, California, discovered in Oc- 
jabeiss 1865, by H. NM. Bolander, and named for him, one of 
a) 
strongly omer: mature heads 4-5 lines in diameter, brown, 
uncled; flowers 2 lines long, with very narrow and sha 
pointed sepals, and very slender stamens; shape of capsule 
quite peculiar; seeds 0.25 line long, with about 8 ribs visible. 
The flattened stems and the brown heads assimilate this spe- 
cies to the Californian Ensifolii, but the rounded and strongly 
knotted leaves and the sessile flowers seem to separate it from 
them and place it with J. scirpoides and its allies.
