 fornia from Tehama and Butte Counties in the north to the very south and 

 to northern Lower California. Toward the east it is found in southeastern 

 Nevada, Lincoln and Clarke Counties (where the type was collected), Ari- 

 zona (except probably in the northern and northeastern part of the state), 

 southwestern New Mexico (probably not north of Socorro County and not 

 east of the Rio Grande), and northwestern Texas (El Paso and Jeff Davis 

 Counties). There is a specimen in Herb. N., collected by Fremont, ** on 

 road day we left Canyon Arkansas River Aug. 28," 1845 (No. 402^, st.) 

 which would mean Colorado if the locality is correctly given. I have seen 

 no other specimen of our species from that state. The eastern and north- 

 eastern limits of its range need further observation. It is clearly distinct 

 from the eastern S, nigra for which it has been taken by most authors. 

 There seem to be two forms which may be distinguished by the glabrousness 

 or by the more or less coi)ious pubescence of the young and the one-year- 

 old branchlets; the more pubescent one would have to be taken for the
