toria chalybeiformis were gathered on trees. On dry ground out- 

 side the swamp Clad onia jure ata was found, and a little Cladonia 

 rangiferina. On the rocks of the deciduous forest outside the 

 swamp, Lecanora cinerea, albocaerulescens and Crocynia lanu- 

 ginosa were common. Lecanora tar tar ea and Cetraria glauca were 

 also found on rocks. 



Mosses and liverworts carpeted the swamp floor together 

 with sphagnum. Hypnum imponens was fruiting commonly. The 

 gemma cups of Georgia pellucida were collected. On dryer ground, 

 Bryum caespiticum was in fruit. One of the fallen logs in the 

 swamp was covered with a hairy liverwort {Ptilidium pulcherri- 

 mum) fruiting abundantly. Others in the swamp were : Bazzania 

 trilobata, Pallavicinia lyellii, and Calypogeia trichomanis on rot- 

 ting logs. The tiny brown Frullania eboracensis was common on 

 the trunks of deciduous trees. 



The cedar swamp is one of the finest wild spots left near 

 New York City. Dense thickets of Rhododendron maximum form 

 the undergrowth, the red cedar and hemlock are the dominant 

 tree growths. Along the stream in the swamp are typical wet 

 ground species; button bush, kinnikinnik, witch hazel, red maple 

 sweet pepper bush, and high bush blueberry. 



On return to the city, the party was entertained for supper 

 at the home of Miss Eleanor Friend and afterwards the speci- 

 mens gathered were reviewed.
