by the late Raymond H. Torrey who inspired many of the local 

 students of lichens. By digging through the snow in an appropriate 

 spot, enough of the Cetraria was brought up to convince one of its 

 existence under the winter cover. In addition to the two commoner 

 species of rock tripe, Gyrophora Muhlenbergii and Umbilicaria 

 penns\lvanica were collected on the projecting rocks. These also 

 harbored Biatorclla simplex, Acarospora fuscata, Stereocaulon 

 paschale, Lccanora ruhina, and Rinodina oreina. Alectoria chaly- 

 beiformis, Cetraria Oakesiana, and Parmeliopsis aleurites grow 

 on the trees along the trail. 



On the return trip, a small amount of Baeomyces rosciis was 

 dug out of the snow on the dirt road leading into Island Pond and 

 an exposed road-cut which had melted out during the day yielded 

 several more lichens, including Cladonia bacillaris f. clavata, 

 Cladonia coniocraea f . ceratodes. Cladonia chlorophaea fifs. simplex 

 and carpophora, Cladonia furcata var. pinnata f . foliolosa, Cladonia 

 cristatella f . vestita, and Cladonia plenrota.

Trip of March 31 to Floyd Bennett Field 



Salt marshes are perhaps the least affected by adverse climatic 

 conditions of any of our native habitats and are interesting through- 

 out the year. The winter season really has one advantage in that 

 there are no mosquitoes. The area which was visited — salt marshes 

 west of Flatbush Avenue, Brooklyn — is one of the very last bits of 

 natural terrain within the limits of New York City, but with the 

 projected improvements in connection with Marine Park this wild 

 condition will probably not endure. On the elevated portions of the 

 salt marsh can be found a good growth of Baccharis and Iva, our 

 two shrubby composites. There are plants of seaside goldenrod, a 

 peculiar Lactuca, various grasses and sedges, and in the fall the 

 marsh borders are rimmed with Sabatia stellar is. One of these little 

 islands is a miniature sand dune covered with Hudsonia tomentosa, 

 associated with Cyperus Grayii and Carex silicea. The remains of 

 Salicornia europaea and the perennial 5. ambigua were here in 

 abundance, also Atriplex patida, A. arenaria, and Suaeda linearis. 

 Distichlis spicata and Juncus Gerardi form the chief grass-matting 

 of the salt marsh. In the wetter places there is plenty of Spartina
