130 CRYPTOGAMIA. 



Ramalina striatula, N. ab. Esenb. fide herb. Kunz. 

 Ramalina sepacea, Pers. ined. in herb. Montag. 

 Ramalina microcarpa, Pers. ined. fide. cl. Van den Bosch. 



Hab. Lagunas and Valparaiso, Chili. — Found throughout South 

 America, and northward to Texas (Mr. Wright), and Louisiana (Dr. 

 Hale). It is also a native of Nepal (Herb. Hook.) and other parts of 

 the East Indies ; of New Holland (Sieber) and of South Africa. R. 

 stramima (Pers.) Ach. possibly relates to this lichen ; but Persoon's 

 description is too imperfect, as Acharius (Syn. p. 295) admits, to de- 

 termine anything. Parmelia Berterii, Spreng., under its earlier desig- 

 nation of Cornicularia (Neue Entd. p. 98, fide auct.) may be next in 

 priority, but cannot be taken for a precise determination, as the author 

 not only included in his species the distinct R. rigida (Pers.) Ach., 

 but subsequently described the Cape form of our Lichen as a new spe- 

 cies (R. EcJdoni), and again (R. Celastri). There remains the name 

 given by Fries, which was, if we are not mistaken in the above, the 

 first distinct indication of what has proved a remarkable and wide- 

 spread species.
