and climbers interested in botany, whose vacations take them 

 into the North Woods, will find there many species of Cladoniae 

 which are absent or rare in the range of the Club within 100 

 miles of New York City. Some of these northern species are 

 strikingly tall and robust, compared with those of lower lati- 

 tudes, and others are extreme in their fantastic and intricate 

 forms of branching. 



Thanks are due to the friends who volunteered to collect 

 and send to the writer ample specimens, found on their vaca- 

 tion trips, in the North Woods. Specimens from Gaspe, Quebec, 

 along the north shore and in the Gaspe National Forest, near 

 the Federal Zinc and Lead Mine, 48 miles inland from the Bay 

 of Chaleur on the south shore, and from Maine and New Hamp- 

 shire, were collected by the writer; on a trip made possible by 

 Mr. Alexander Jessup, who supplied transportation in his auto- 

 mobile; and in the Adirondacks, through similar helpfulness by 

 Mr. LeRoy E. Kimball. Those who sent specimens were as 

 follows: 



Mr. George F. Dillman, from Schroon Lake, Santanoni 

 Mountain, Hurricane Mountain and Mount Mclntyre, in the 

 Adirondacks; Mr. Archibald F. Shorey, from the Great Range 

 and Cranberry Lake, in the Adirondacks; Mr. John W. Thom- 

 son, Jr., from western Maine; Mr. Frederick K. Vreeland, from 

 South Pond, near Long Lake, and Blue Mountain, in the 

 Adirondacks; Mr. Vincent Schaefer, of Schenectady, N. Y. 

 from Panther Gorge on Mount Marcy, Adirondacks; Mr. My- 

 ron H. Avery and Dr. J. F. Schairer, of Washington, D. C. 

 from Mount Katahdin and Chairback Mountain, northern 

 Maine; Mr. E. H. Walker, of the Smithsonian Institution, 

 Washington, D. C, from Mount Washington, N. H.; Mr. M. 

 L. Joslin, of Burlington, Vt., from Lincoln Mountain, Couching 

 Lion and other Green Mountain summits, in Vermont; and 

 Mrs. Laura Woodward Abbott, of Bristol, Pa., from Jay Peak, 

 Vermont. 



Acknowledgments are again due to Dr. Alexander W. Evans, 

 of the Osborn Botanical Laboratory, Yale University, Professor 

 of Botany, for continued helpfulness in the determination of 

 these northern species; and, in some cases, for confirmations or 

 precise determinations by Dr. Heinrich Sandstede, of Bad 

 Zwischenahn, Oldenburg, Germany, to whom Dr. Evans sent
