274 W. M. Fontaine — Mesozoic Plants from California. 



road, south of the Oroville Table Mountain, near the Banner 

 gold quartz mine." 



These are the plants referred to in the beginning of this 

 paper. 



Mr. Ward's collection, although much larger than that of 

 Mr. Stanton, and containing better preserved specimens, still 

 shows very imperfectly the character of a number of plants. 

 Enough is made known, however, to prove that they are dis- 

 tinct species, but either the amount of material, or the state of 

 preservation, does not suffice to fix with precision the identity 

 or the affinity of the form. It is for this reason that the loca- 

 tion of certain plants in the following list is left in doubt. 

 The list below gives the plants made out with more or less 

 definiteness from the Oroville beds.

Whatever may be the true place of these 27 forms, they are 

 all different. The flora does not seem to have had great 

 variety, but judging from the number of specimens, such 



* I prefer the name " Cladoplilebis" for these plants, which Heer regards as 

 Asplenium.
