In 1859, Tuckerman described (Amer. Jour. Sci. & Arts, 28: 

 203) a new Cetraria from California which he named after the 

 State. This plant has been the object of much discussion, and 

 as in the Bryologist (13 : 28. 1910), during the past year, it was 

 definitely attributed by Mr. G. K. Merrill to the genus Alectoria, 

 we must consider it in the present paper. Let us follow its his- 

 tory chronologically. The plant was collected at Monterey by 

 Menzies, and specimens were given to Tuckerman. The type 

 material is in the Tuckerman Herbarium, Botanic Museum, Har- 

 vard University, Cambridge, Mass. Tuckerman's original de- 

 scription was as follow : " thallo caespitoso cartilagineo anguloso 

 lacunoso-subcanaliculato opaco e viridi fusciscente ramis irregu- 

 lariter subdichotome ramosis patentibus, fertilibus superne incras- 

 satis ; apotheciis terminalibus appendiculatis margine dentato- 

 fimbriatis demum convexis nigris." This latter was translated 

 by Mr. Merrill (Bryologist, 1. c), but he inadvertently failed to 

 render " anguloso." Tuckerman added to his original descrip- 

 tion : " Fronds in small, roundish masses, many branches diverging 

 from a single base, with the aspect rather of a small slender state 

 of Ramalina calicaris, /?, than of the erect Cetrariae, to which, 

 and in particular C. tristis and C. aculeata, it is indeed, if I mis- 

 take not, nearest allied. The station, upon trees, and on the 

 coast of California, is a very Unlikely one for C. aculeata, from 

 which the present also differs remarkably in habit of growth, 

 and in color. Though more than seventy years have passed since 

 the venerable botanist who gave me these specimens collected 

 them, they appear to be undescribed." 



In 1858-60 (Synop. Lich. 300), Nylander makes the next im- 

 portant reference to the species in a footnote under C. aculeata 

 Fr. where he writes: " (1) Forte varietati horrescenti Nyl. Prod, 

 p. 194 affinis sit Cetraria calif omica Tuck. Suppl. 2, p. 203, ' thallo
