tablished on a roadside embankment adjacent to open scrub- 

 growth by the fence-line. This colony also showed vigorous 

 plants over five feet high. Toward the village and within 

 about a mile of it another colony of apparently the same species 

 was noted in conspicuous bloom in a field close to the road, but 

 there was not opportunity for examination nor for the obtaining 

 of material. Later in the season, September 19, and on the 

 other side of the village still another collection was made from 

 a fair abundance of the plant scattered over a grassy-weedy 

 field, unplowed, and apparently mowed for hay. In adjacent 

 fields, and a quarter-mile or more out from the village, plants 

 from several more colonies were examined and verified as the 

 new introduction. 



The most recent collection made by Mr. Pretz was on August 

 14, 1 92 1, near Walbert's, a station on the Catasauqua & Fogels- 

 ville Branch of the Philadelphia & Reading Railway. The plant 

 here grew abundantly about the edges of a cultivated corn-field, 

 close to the fences. 



Additional information on the plant about Allentown is 

 furnished by a collection made by Mr. Walter Benner, July 21, 

 1920, on a lot near 27th and Liberty Streets. This is a section 

 of the city where there are few buildings but a considerable 

 tract is laid out in building lots, and some are used as truck- 

 patches. A year or two previously this particular lot apparently 

 had been under cultivation, but was now grown up with Lactuca 

 Scariola and numerous other weeds — among which Sonchus 

 uliginosus had made a rather dense growth. 



These stations in Lehigh County lie in a fairly circumscribed 

 area — within about a five-mile westerly and southerly radius 

 of Allentown. 



Mr. Benner had become familiar with the plant near Allen- 

 town and during the following summer, in his vigorous collecting 

 in Bucks County (the area in which he specializes), he detected 

 it near PleavSant Valley, August 15, 1921, growing in a cultivated 

 field which was then in grass but previously had been in grain. 

 The plants were scattered over one end of the field, standing up 

 conspicuously above the low grass. This locality is ten miles 

 east of the nearest previously known station, Emaus.
