 ders of California near Mono Lake, Brewer. 



* * * * Nutlets narrowly ovate, affixed hy their whole length to the subulate gyno- 

 base by a very narrow groove having a viore or less widened base, one of tlieni 

 tvithout lateral angles (as in 9 d: 10), the other three ivith their lateral angles 

 extended into a continuotcs broad and somervhat crenate or 2)ectinate wing, rarely 

 all four winged. 



17. E. pterocaryum, Torr. Slender annual, hirsute, loosely branching : leaves 

 linear or the lowest spatulate : flowers in naked and mostly bractless geminate or 

 cyraosely clustered spikes : calyxdobes oblong or in fruit ovate, enclosing the nut-

 re^^ion from the borders of British Columbia to New Mexico and tlie borders of Texas. Nutlets

 Calyx 5-parted, persistent, spreading or reflexed in fruit. Corolla short-salver- 

 form and with conspicuous arching crests at the throat. Short filaments, style, 

 ovary, &c., as in Eritrichium. Nutlets 4, erect, attached by their ventral angle for 

 most of their length to a subulate or broadly pyramidal gynobase^ the sides sur- 

 rounded by one or more rows of rigid prickles with backwardly barbed (glocliidiate) 

 tips, either distinct or confluent into a border or wing, the back unarmed or some- 

 times similarly prickly, — forming a bur, Avhich is carried in the wool and hair of 



animals. — DC. 1. c. 



A genus of about 30 species.'mostlv rather coarse and small- (blue- or rarely white-) flowered

 merely spreading, stout, shorter than the narrow and at length unequal lobes ot the 

 calyx, which mostly exceed the fruit : corolla small, a line or two long, blue : nut- 

 lets bordered by a single row of subulate barbed prickles, their bases often broad- 

 ened and more or less confluent; the back and sides thickly beset_ with irregular 

 sharp points or tubercles; scar and gynobase slender. —^. Redowskii, var. occiden-
