* * * * Nutlets narrowly ovate, affiled by their whole length to the subulate gyno- 

 base by a very narrow groove having a more or less widened base, one of them 

 without lateral 'ingles (as in 9 <fc 10), the other three with their lateral angles 

 extended into a continuous broad and someivhat crenate or pectinate wing, rarely 

 all four »i,iged. 



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

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

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 I. erect, attached by their ventral angle for 

 mosl of their length to a subulate or broadly pyramidal gynobase, the sides sur- 

 rounded by one or v rows of rigid prickles with backwardly barbed (glochidiate) 



tips, either distinct oi ifluent into a border or wing, the back unarmed or 



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

 animals. 1 M '. 1. c.

1. E. Redowskii, Lehm, Annual, roughish hirsute, a span to a fool ot two 



high, much branched: leaves linear. Ian late, or the lower somowhal spatulate, 



obtuse; the upper becoming bracts of the loose leafy spikes: pedicels civet or 

 merely spreading, stunt, shorter than the narrow and at length uuequ i the 



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

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