 high, much branched: leaves ovate lanceolate, coarsely dentate. 

 1 to i}4 in. long accuminate at apex, narrowed at base, not 

 prominently nerved, petioles }2 in. long; flowers dull purple in 

 almost leafless thyrses averaging 6 in. in length; bractlets most- 

 ly opposite, slender ascending; calyx ovate, acute shorter than the

 part of the plant. 



The Geiwis Dirina irv North America. 



BY DR. H. E. HASSE. 



In 1872 Tuckerman wrote (Gen. lyich. p. 130), "It (Dirina) 

 has not yet occurred nearer to the North American continent 

 than the Sandwich Islands." It will hence be of interest to 

 Lichenologists that this Lichen, hitherto known from the Eng- 

 lish and Mediteranean coasts, from Chili, Japan and Sandwich Is- 

 lands, has now been found to be represented by two new species 

 on this continent, both occurring within the boundaries of Los 

 Angeles county. Dr. A. Zahlbruckner, of the Botanical De- 

 partment of the Royal Museum of Vienna (the author of our 

 species), alluded to the circumstance that, true to the predilec- 

 tion of this Genus these two species likewise favor a maritime 

 habitat, conforming herein to Roccella, to which, according to 

 the views of recent authors, Dirina is allied. This view has 

 been foreshadowed by Tuckerman (1. c.) and others. 



Dirina rediunta (Stiz.), Zahlbr., was found by the writer in 

 1S95 on Catalina upon the bark of Heteromeles arbutifolia, and 

 sitice also on the mainland upon the California Walnut and
