FIELD TRIPS OF THE CLUB 

 Trip of June 16-19 to Lancaster, Pa. 



The Muhlenberg Botanical Club of Lancaster entertained 

 members of three other botanical societies during this four day 

 meeting. Seven members of the Torrey Club were among the 

 thirty-five attending. From the "Willows," a tourist camp just 

 east of Lancaster, the party on Thursday visited points of 

 historic interest in Lancaster, including the birthplace of 

 Henry E. Muhlenberg and a massive buttonwood near Rohers- 

 town — the largest tree in Pennsylvania. Several limestone lo- 

 calities were visited for their interesting plants, including Scott's 

 Spleenwort, Rue Spleenwort and a fine stand of Smooth Clifif 

 Brake growing on an old limestone bridge. Both the Smooth 

 and the Purple Cliff Brakes grew close together in the mortar 

 joints, affording an excellent opportunity to compare them. 



In the evening Prof. Herbert H. Beck read an interesting 

 paper on Muhlenberg the Botanist. This was followed by an 

 informal talk by Dr. Edgar Wherry on the geology and plant 

 associations of the areas which the group was to visit. 



On Friday a visit was made to Bush River, Md., stopping 

 several times along the way to explore localities of interest. 

 The white spikes of Aletris farinosa were conspicuous at many 

 points along the road. Two stations for Adder's Tongue fern 

 were visited near Bush River. The high point of the day was the 

 finding along the tidal shores of the river of Isoetes saccharata, 

 Lilaeopsis chinensis and Eriocaulon parkeri, growing together 

 at low tide level. 



Saturday the serpentine barrens in southern Lancaster 

 County were visited for their peculiar associations. One of the 

 most interesting of the plants limited to serpentine rocks was 

 the small Talinum teretifolium growing in the fields. Another 

 interesting plant was Cerastium arvense var. villossimiim. Other 

 plants noted because of being in fine bloom were Goat's Rue in 

 large masses. Lobelia spicata and Campanula rotundifolia. A 

 side trip was made to nearby Maryland to see the Hairy Lip 

 fern. 



On Sunday an entirely different habitat was visited in north- 

 ern Lancaster County, rich woodland and sphagnum bogs. One 

 open bog was pink with Rose Pogonia. Other plants observed
