gonica. A less hasty survey would have undoubtedly yielded 
more similar plants. 
I give below a list of the major portion of the plants of which 
I obtained specimens, even of many very well known species. 
My excuse for so doing must be that the flora of this region has 
been hitherto almost unknown, that nearly one-third of the list 
have their geographical range extended as given in the State 
Survey volumes on botany, that many novel and interesting forms 
were obtained, and that several others have here their second 
known station recorded. 
The collection from the Sutter plains and the Buttes was 
made on April 20, 1891; that from the Feather River on the 
day previous. 
Clematis lasiantha, Nutt in Torr. and Gray, FI. i. 9. 
Up to about goo ft. 
Ranunculus Eiseni, Kellogg, Proc. Calif. Acad. vii. 115. 
Sufficiently distinguished from R. Californicus by its smaller 
size, hairiness, cuneiform segments of the three-parted radical 
leaves, and fewer (commonly five) petals. Sutter plains. 
Ranunculus hebecarpus, H. and A. Bot. Beechey, 316. 
Lower cajion sides, South Peak. 
Delphinium variegatum, Torr. and Gray, FI. i. 32. 
Sutter plains. 
Delphinium decorum, F. and M. 3rd Ind. Sem. Petr. 
Wooded cafions, South Peak. 
BERBERIS DICTYOTA. Erect, only six inches high: leaflets 
commonly five, sometimes only three or four, not crowded, 
coriaceous, ovate with undulate margins and spinose teeth, 
one to two and one-fourth inches long, pale green below, 
bright shining green above, very strongly reticulated on both 
faces: racemes terminal, clustered, 9-12 lines long: fruit un- 
known. 
The mark of this species as compared with &. pzvnata, which 
it mostly resembles, is in its few, coriaceous and strongly 
reticulated leaflets. These, with the rigid acuminate teeth and 
undulate margins, give the plant a very spiny appearance. Only 
One specimen seen and that near the rocky summit of South 
Peak,
