three stations on Long Island. Although Robbins regarded it as 

 a plant of the coastal plain, I found it in great quantity, in 

 September, 1937, on Shawangunk Mountain, Ulster County, 

 N. Y., 75 miles from the Atlantic Ocean and at 2,000 feet ele- 

 vation, which shows how much more there is to be learned 

 about the ranges of Cladoniae beyond the sometimes meagre 

 records of available references. 



Increasing acquaintance with the Cladoniae of Long Island, 

 with the aid, in determinations, of Dr. Alexander W. Evans, 

 of Yale University, to whom I owe thanks for his prompt 

 identifications of material, and his kind guidance in further 

 pursuit of the genus, led to curiosity as to Cladonia associations 

 on other unsubmerged portions of the terminal moraines of the 

 last Glacial Period, off the southern coasts of New England, 

 such as Block Island, No Man's Land, Martha's Vineyard, 

 Nantucket and Cape Cod. So far, I have made collecting trips 

 to the last three, and have yet to reach the first two. As my 

 trips were the first any botanical student ever made, to Mar- 

 tha's Vineyard and Nantucket, for the study of Cladoniae, at 

 least since the genus has been reorganized by Vainio, Sandstede, 

 and Anders, in Europe, and their re-classifications have been 

 followed in the United States, by Robbins, Blake and Evans, 

 they will be the principal subject of this paper. Dr. Evans has 

 made some studies of the Cladoniae on Cape Cod, and I have 

 sent him material from there, and I hope he will give us a paper 

 on that region. 



I spent two days on Martha's Vineyard, in June, 1936, 

 with James Murphy, of Brooklyn, New York, a fellow member 

 of the Torrey Botanical Club, who has been a companion on 

 hunts for Cladoniae in many remote places from North Caro- 

 lina to Gaspe. We crossed the island, from Vineyard Haven, 

 through the oak and pinewoods, to West Tisbury, examined 

 the open, grassy moraine north of Squibnocket, and followed 

 the beach and the shores of the numerous long narrow fresh 

 water ponds along the south side of the Island, east to Edgar- 

 town. 



The conditions are very much like those on the eastern half 

 of Long Island, and the Cladonia associations similar, although 

 more numerous, especially on the barren, sandy soils around 

 the southern ponds. Large colonies of robust Cladinae and Unci-
