land (Hue, Stizenberger, Macoun) on the east coast. On the 

 west coast from Oregon (Stizenberger) to Alaska (Macoun, Cum- 

 mings). Other stations are: Washington (Roell), Quebec (Ma- 

 coun), Newfoundland (Tuckerman, Macoun, Eckfeldt, Stizen- 

 berger, Arnold), Hudson bay (Macoun), Miquelon island (Sti- 

 zenberger), Davis strait (Stizenberger) , Labrador (Arnold), 

 and Ungava. 



Observations : That this variety is little understood by most 

 students, is evidenced by the varied examples referred to it in 

 herbaria. The fact that it has been called both a variety of the 

 erect ochroleuca and the pendulous sarmentosa shows also that 

 its classification has been difficult. This condition of affairs is 

 not to be wondered at as Fries' original description if taken alone 

 is not at all diagnostic, nor does it mention what has long been 

 accepted as its most diagnostic feature, i. e., a foveolate thallus. 

 The loss of the type may have also aided in the dilemma. 

 It is unquestionable that Tuckerman, a close follower of Fries, 

 properly understood the plant, and he used the four diagnostic 

 terms: "prostrate," " rigid," " dilated,"' " lacunose." Nylander 

 also called it " prostrate," " compresso crassiore," " magis lacu- 

 noso vel lacunis." Th. Fries " prostratus," " rigidulus," " scobic- 

 ulato-foveolatus." As Fries placed it between his " fruticuloso " 

 ochroleuca and his " pendulo " sarmentosa; and as it seems to be 

 a transitional variety spanning the gap between the reduced, caes- 

 pitose, boreal ochroleuca and the more luxuriant, pendulous, sub- 

 boreal sarmentosa it should be naturally considered a variety of 

 the former, the first of the three plants described. Moreover 

 sarmentosa and Cincinnati show absolutely no intergradation where 

 their ranges meet. 



Note: Alectoria luteola DeN. ex Del. Giorn. Bot. 2: PL I, 

 Tom. I. 206. 1846. Reported from Newfoundland by Stizen- 

 berger, 1. c. 125, and originally described as follows : 



" Alectoria luteola Delis, herb! 



" Evernia luteola Montagn. herb ! 



" Trovasi a Terra nuova nell' America settentrionale, secondi 

 esem plari del chiarissimo Montagne, e dell' erbario dello stesso 

 Delise favoritimi dall'illustre Lenormand, 



" Tallo fili forme lunghissimo di color giallo pallido, levigato,
