264 PROCEEDINGS OP THE AMERICAN ACADEMY 



xvii. 225, I had too confidently guessed this little plant to be the 

 Cynoglossum ciliatum of Douglas, which is possibly a congener, but 

 for the present is taken for an Echinospermum. But Mr. Cauby, by 

 collecting the fruit, has made it clear that the present plant is, as its 

 habit would denote, a congener of 0. 7iana. As far as known, the 

 present species has the edentate nutlets of 0. riipestns, especially of 

 the form which Maxiraowicz named EritricJmim Maackii ; but from 

 its analogy with that species we may expect varieties with more or 

 less pectinate teeth on the angled border.*

* 0. RUPESTRis (Mjjosotis rupestris, Pall., Erilrichium rupeslre, DC.) would be 

 the proper name of this N. Asiatic sjiecics, which, according to Maximowicz 

 (Diapn. Dec. xi. 540), includes also E. pectinatum, DC., as a form with pecti- 

 nately frintred border to tlie nutlets. Herder keeps up two species, but ap- 

 parently refers too many Himalayan forms to tlie latter. 



O. viM.osA. Erilrichium villosutn, A. DC. Prodr. x. 126, cum syn. E. Inti- 

 foUum, Rnprecht? Herder's reference to tliis as found on our Kocky Mountains 

 was causeil by taking the name from S. Watson, wlio (in Bot. King, 240) fol- 

 lowed Hook. f. in his Memoir on Arctic Plants. Some forms of 0. nana do 

 indeed much resemble O. villosa. 



O. SciiKF.NKii = Echinospermum rupestre, Schrenk in " Bull. Acad. Petrop. ii. 

 194," & DC. Prodr. x. 140. This has the habit of 0. npestris, and, although 

 anomalous, should go with it rather tlian into Echlnonpermum. The nutlets are 

 quite erect, indeed, but their narrow wing is strictly turned over upon the back, 

 and the few and short teeth which it bears are not at all glochidiate.
