The two forms of Myosurus found on the San Diego mesas are 

 named by Rev. E. L. Greene, in a monograph of that genus now

Washingtonia filifera, Wendland, is not, as heretofore stated,

 native of Mexico. 



Brahea edulis is a synonym of Erythea edulis, Watson, and B. 

 glauca, B. armata and probably B. Roetzlii are synonyms of E. ar- 

 mata.
