a few miles beyond we collected Rynchospora alba, Coptis tri- 

 joliata, Andromeda glancophylla, Epilobium lineare, Dryopteris 

 spinidosa, D. cristata, D. boottii. Equisteum silvaticmn, Alectoria 

 chalybeijormis, Evernia prunastri, Cetraria juniperina, and Par- 

 nielia olivacea. 



The station for Braun's Holly Fern, Polystichum braunii v. 

 purshii, furnished the event of the afternoon. In this bouldered 

 ravine we saw the brilliant red berries of Actaea rubra, the pearl 

 ones of A. alba, and collected Cystopteris bulbifera, Camptosorus 

 rhysophyUa, Phegopteris polypodioides, P. dryopteris, Dalibarda 

 repens, the leaves of Oxalis acetosella and Hepatica acutilobata, 

 and Circaea alpina. Frequent gustatory sallies on the fruit of Rubus 

 strigosus should also be chronicled. 



Sunday morning a swamp nearby was visited to collect Dry- 

 opteris clintoniana from the only reported locality in Wayne 

 County. Then a drive toward a bog near Lakewood, Pa., where 

 were hundreds of Sarracenia purpurea in bloom along with the 

 white spikes of Habenaria blephariglottis. This is a typical moun- 

 tain bog filled with sphagnum and roots of Kalmia caroUniana, 

 K. polijolia, Andromeda glaucophylla and the small cranberry, 

 Oxycoccus palustris. Here was collected Eriophoruw, virginicum 

 and the ripe E. callithrix, Nemopanthus mucronata, Carex pauci- 

 flora, and Menyanthes trifoliata. The edge of the bog was fringed 

 with small trees of Larix larcina. The lower branches of these were 

 fringed with a lacy pattern of Parmelia physodes, P. olivacea, and 

 punctuated with the golden-banded Cetraria juniperina. Twigs were 

 hung with tufts of Alectoria chalybeijormis. Other plants of the 

 bog and surrounding swamp included Calla palustris, Habenaria 

 tridentata, Rosa Carolina, and Cornus canadensis. On the pasture 

 land adjacent to the swamp there was enthusiastic search, and suc- 

 cessful, for grape ferns at this southernmost range extension for 

 BotrycJiium multifidum. Ten minute stops were made at Preston 

 Center to collect the Ostrich Fern (Pteritis nodidosa) , and at Little 

 Hickory Lake where were seen Dianthus deltoid es, Galium verum, 

 Eleocharis obtusa, E. acicularis, and MyriopJiylliim tenellum. 



Then to the station for Thelypteris simulata through a heavy 

 ground cover of Taxus canadensis. The Massachusetts fern here 

 covers quite a large area surrounded and at times almost completely 

 hidden by shoulder-high fronds of Osinunda cinnamomea.
