CALIFORNIA WAKE ROBIN (Trillium sessile, L.). The tril- 

 liums are low-growing, perennial herbs of the spring, and read- 

 ily distinguished by their stout, naked stems bearing at the 

 top a whorl of 3 ample, netted-veined leaves in the midst of 

 which the solitary flower opens. In T. sessile (a widely dis- 

 tributed species, represented on the Pacific Coast by a robust 

 form which botanists designate as variety calif ornicum), the 

 flower is stalkless and sits upon the leaves, which are more or 

 less blotched with brown. The petals are from 1 to 4 inches 

 long, erect, and remarkable for their variability of color, usu- 

 ally purple or dull red, but even found white or greenish-yellow. 

 The California Wake Robin is met with in moist hillsides and 

 woods, from San Diego County, California, to Oregon, and 

 blooms from March until May. 



A less common species, indigenous to the Coast Range 

 woods from Santa Cruz northward to British Columbia, is 

 T. ovatum, Pursh. Its fragrant flowers are white, eventually 

 turning to rose, and are borne on peduncles 1 to 3 inches long.
