BY MARY K. CURRAN. 



Sidalcea calycosa, M. E. Jones, Am. Nat., Aug., 1883. 

 S. sulcata, Curran. Bull. Cal. Acad. i. 79. 



Dr. Gray has called my attention to the earlier publica- 

 tion of this species, which I had overlooked. 



Yerbesina encelioides, Benth. & Hook. Along the road- 

 side for several miles near San Buenaventura. July, 1885. 



Centunculus minimus, L. Near Antioch, May, 1884. 



Lysimachia thyrsielora L. Big Meadows, Plumas County, 

 Collected by Mrs. Austin, 1884. 



Acanthomintha lanceolata, Curran, of which only one 

 plant had been previously collected, was found in July of 

 this year covering rocky hillsides in Slack Canon, Monterey 

 Count}'. 



Zosteba marixa, L. On the seashore near Santa Barbara, 

 July, 1885. 



Classification of the Eriogoneai as affected by some connecting 



forms. 



The genera composing the tribe of Eriogonece are becoming 

 every year more uncertain and ill-defined by the discovery 

 of intermediate forms. One genus after another has been 

 merged either into Eriogonum or Chorizanthe, each one of 

 course modifying the character, until at present Erigonum 

 is separated from Oxytheca only by the spine-tipped involu- 

 cres of the latter, and the only definable difference between 

 Oxytheca and Chorizanthe is a comparatively slight one of 

 form and texture of the involucre, which may disappear with 

 the next species discovered. 



If genera are to be accepted, whether definable or not, as 

 matters of convenience, then Oxytheca should be maintained, 



Issued December 14, 1885.
