No. 7728, collected April 20, at Sunset, Kern county, on 

 dry gravelly hillsides. It differs from no. 7590 only in the more 

 pronounced serration of the leaves. 



No. 7762, collected April 24, on the desert about three 

 miles southwest of Mojave, Kern county, growing in sand. It 

 differs from the other numbers in having entire leaves, larger 

 flowers without the red dots in the throat. This may be S. 

 campestre kelianthemijloj^um (Levi.) Aven Nelson, but the 

 writer has seen no description of that plant. 



Chylisina clavaeforinis (Torr.) 



Oenothera clavaeformis Torr. Frem. Rep. 314. 1845. 

 Oenothera scapoidea var. aurantiaca Wats. Proc. Am. Acad. 



8: 595- -^^ITi- 

 Chylisnia scapoidea clavaeformis Small, Bull. Torr. Club, 



33: 194. 1896. 

 No. 7691, collected April 14, at Randsburg, Kern county, 

 where it is plentiful on stony hillsides. The capsule in our 

 specimens is shorter than the pedicels, in which it does not 

 agree with the original. Even if our plant should prove to be 

 distinct, the original clavaeformis is certainly more than a form 

 of scapoidea. 



Epilobium minutum Lindl.; Hook.Fl. Bor. Am. 1: 207. 1833. 

 No. 7950, collected June i, opposite Upper Soda Spring, 

 Siskiyou county, growing on rich wooded slopes, the slender 

 erect plants abundant in a limited area.
