Mr. Greene under the name of ‘ Pittonia’’ or in his “Flora 
. Franciscana.’’ The references of the few exceptions are given. 
No attempt has been made to verify all of the species. Todo so 
would, in many cases, necessitate the partial revision of large 
genera and the study of priorities, involving an amount of time 
not now at the disposal of the writer. For these reasons the two 
score new species and the various genera ‘‘instituted’’ within 
the limits of the old genus Eritrichium and the numerous species 
of Delphinium, Trifolium, Potentilla, Erigeron, Cnicus, Senecio, 
-Microseris, etc., are here neglected, as well as many of the 
of the Cruciferee. Fortunately for the interests of science 
the larger number of the types are in the herbarium of 
the California Academy of Sciences. The later ones are 
being mounted and rendered accessible in the herbarium of 
the University of California at Berkeley, and if the notes given 
under the species seem to bear hardly upon the capacity or 
the judgment of Professor Greene, the means of proof or dis- 
proof are in most cases at hand. 
Thalictrum cestum Greene is apparently 7. polycarpum Wats., 
but that species is so near 7. Fendleri that it is uncertain to 
which it had better be referred. 
Thalictrum hespertum and C. playtycarpum Greene are forms of 
I. Fendleri Engelm. Mr. Greene keeps the name up, although 
he says it ‘‘seems almost or quite confluent with 7. Fendlert of 
the southern Rocky Mountains.’’ * 
Ranunculus Bolanderi+ Greene is, according to Dr. Gray, 
typical RP. alismefolius Geyer. 
Ranunculus Biolettii Greene is R. pusillus var. Lindheimert 
Engelm. It has been collected by the writer at Folsom, and 
about ponds near Olema, where it is common, it is often a foot 
or more in length. 
In Flora Franciscana Mr. Greene describes 2. pusil/us Poir, 
and remarks: ‘‘ Rare in California, though common in the south- 
ern Atlantic States; found in Napa Valley, Azge/ow, and in 
Marin Co., 7, P. Moore. The akenes are either smooth or 
rough in even the eastern plant, so that the designating of ours-
