Rhodora 34: 146-147 (1932), and another by Walter M. Banner 

 in Bartonia 15:33 (1933). These published articles list about 

 twenty localities in Massachusetts, Connecticut, New York, New 

 Jersey, Pennsylvania, and the District of Columbia, the earliest 

 record being one from 1922. 



Since this time many additional localities for the plant have been 

 recorded by wide-awake collectors, so that now it is known definitely 

 from at least eighty-eight places in the eastern states. A number of 

 earlier records have also been discovered. Its rapid spread seems to 

 indicate that it will soon.be a very common weed in America. It 

 seems desirable, therefore, to record fully at this time all that is 

 known of its earliest history here, and to trace, if possible, the 

 course of its spread year by year. 



Persicaria longiseta seems to have been found first in America 

 by Edwin B. Bartram {no. 1312) at Wayne, Delaware Co., Pa., 

 on October 13, 1910. The second record is one by L. H. Lighthipe, 

 who found it as an escape in the garden of Manda's at South 

 Orange, Essex Co., N. J., on October 15, 1912. The next five 

 records were made by W. C. Ferguson, who found it along road- 

 sides at Garden City, Nassau Co., N. Y., on July 1, 1918; in 

 woods at Plattsdale, N. Y., July 2, 1919 ; again at Garden City 

 on August 16, 1920; along roadside and in a yard at Wading 

 River, Suffolk Co., N. Y., June 21, 1922 {no. 1462) ; and again at 

 Garden City on August 16, 1922, where he says it was already a 

 common weed. 



On July 12, 1924, H. E. Stone found it in moist ground of a 

 gutter, Rosemont, Montgomery Co., Pa. On September 21, 1926, 

 William Trimble collected it at West Chester, Chester Co., Pa., and 

 on August 10, 1927, again along streets in West Chester. Dr. E. H. 

 Eames, on October 7, 1927, found it on an old estate at Greenwich, 

 Fairfield Co., Conn., and at several points in much disturbed prop- 

 erty nearby. The same collector located a large colony in a moist 

 shaded low spot near a house at Greenwich, Fairfield Co., Conn., on 

 September 3, 1929. 



In 1930 four more records were added. On September 6 H. E. 

 Stone found it in a garden (presumably as a weed) on Washington 

 Street, West Chester, Pa. ; on September 18 E. H. Eames found 

 another large colony along a shaded moist roadside at Greenwich, 

 Conn. ; on September 27 H. E. Stone collected it from a moist spot
