APPENDIX. 
The author regrets the necessity for the scrappy character 
of Contributions No. 10. In explanation will say that the body 
of the paper was printed last December. It early became ev- 
ident that plates would be needed for the onious. The long 
delay in the preparation of the plates gave the author time 
to accumulate much material and some notes toward clearing 
up certain ambiguous species. “The results were recorded un- 
der “Addenda” along with the changes of view caused by the 
new material. A revision of certain groups of the Nyctaginaces 
of our region was added along with certain changes and new 
names in Astragalus. An unexpected opportunity to make an 
extended trip to the coast through Oregon, Washington and 
Nevada caused the author to distribute that part of the Contri- 
butions already printed and to reserve the plates and notes for 
the Appendix. 
The author wishes to acknowledge his obligation to Mr. 
Diehl! the printer, and editor of the Mammoth Record for assist- 
ance in proof reading and tests of the MS. in my herbarium by 
actual analysis of all the species of onions, using the key and 
descriptions of this Contribution.

sent or present on both forms. The species combines the char- 
acters of A. Douglasii and platycaule, but can be kept separate
