 Unusual Lichen Occurrences 



Search of some of our remoter mountain tops during the past 

 summer, primarily for unusual lichens, has been rewarded not 

 only with rare lichens, but some new stations for northern 

 flowering plants. On the Shawangunk Mountain ridge, at Sam's 

 Point, and northward, were found the boreal lichen, Cetraria 

 islandica, a glacial relict in our territory, and a much rarer 

 boreal species, Cetraria saepincola, which Mrs. G. P. Anderson 

 says was the second station ever reported in the territory of the 

 Torrey Botanical Club, although she found it later in the sum- 

 mer on North Mountain in the Catskills. At the same time we 

 found another station for Potentilla tridentata, on the cliffs of 

 Sam's Point, and also, even rarer in our territory, Arenaria 

 groenlandica, which I have not hitherto seen south of the Ta- 

 conic Mountains (Mount Everett, in Massachusetts and Brace 

 Mountain in New York), although I think it has been found on 

 Spruce Knob, at 4600 feet, in West Virginia. The elevation of 

 Sam's Point is 2250 feet. 



After receiving the rare and beautiful northern Appalachian 

 lichen Parmelia Cladonia, from friends who found it in the Ad- 

 irondacks, and northern New England (Archibald T. Shorey, 

 from Basin Mountain, Adirondacks; Frederick K. Vreeland, 

 Blue Mountain, Adirondacks; Mrs. Laura Woodward Abbott, 

 Jay Peak, Vermont; and George Dillman, Old Speck Mountain, 

 in western Maine), and getting the "look" of the thing in one's 

 eye, I found it in ample quantity on Peekamoose Mountain, 

 3863 feet high, in the southwestern Catskills, in September. It 

 was reported from Panther Mountain, some miles north of 

 Peekamoose, years ago, but the specimen is not available, so the 

 Peekamoose location restores it definitely to the range of the 

 club. I believe it may occur on other remote Catskill summits 

 and shall look farther for it. 



A trip to the Pine Barrens of New Jersey, in the vicinity of 

 Double Trouble, and Wading River, on Sept. 24, with Dr. A. W. 

 Evans, of the Osborn Botanical Laboratory, Yale University, 

 author of the recent authoritative monograph on the Cladoniae 

 of Connecticut (Mrs. Gladys P. Anderson and Mr. and Mrs. 

 William Gavin Taylor providing transportation), proved very 

 instructive to the writer and rewarding to Dr. Evans. He 

 found two Cladonias which are southern species, which have
