{H. B. P., 753 J; and the locality is further described as being "on the road 

 to Upton." Phyt. v. 252, N.S. In Lancashire, it occurred in small quantity 

 "in a paddock near Sedforth Church (near Liverpool), and abundantly in a 

 small yard and about a ruined pigstye ; also where a boiler for steaming food 

 for cattle formerly stood, at no great distance from the first mentioned habitat." 

 George Kirk, in FInjt. iv. 142, N. S. Mr. Grindon, in his British and 

 Garden Botany, records it from " Yorkshire and Cheshire"(^^:». 115^1; but no 

 special localities are given. I have no record of its occurrence in Scotland 

 or Ireland. In many of the above localities the plant was doubtless intro- 

 duced with foreign seed : and when once established, it is not easily eradicated. 

 Its Balsam-like flowers at once determine it : and a good figure of the plant 

 is given in E. B., ed. 3., iL, t. cccxv. A native of Siberia, Russia, &c. 



/. glanduliyera, DC. This plant is not unfrequent in city gardens, 

 where it is known by the name of " Tree Balsam." Mr. Irvine states that 

 it manifests " soms inclination to be one of our spontaneous productions at 

 probably no very distant period" : and also remaks, ' ' I have an anticipation 

 that the Iwpatiens on the banks of the Colne, at Denliam, near Uxbridge, is 

 either the above , or /. canadensis, if there be any such species." Phyt. vi. 

 544, N. S. Mr. Grindon, also, in his British and Garden Botany, observes 

 that it "is fast disseminating itself over the country" f 2^- 115.yi / and has 

 kindly given me the following additional information relative to its appear- 

 ance. He writes, " I have seen it within the last four or five years in various 

 parts of England ; and on enquiry who sowed it, or where it came from, no 

 one knew. Many town gardens in Manchester and the neighbourhood con- 

 tain it j not sown, the people tell me. I have seen it under the same cir- 

 cumstances at the sea-side places on the coast of Lancashire, especially at 

 Lytham, and also not far from the famous old habitat of the American 

 (JEnothera biennis. No one would grow the plant for its beauty, for it is a 

 cumbersome and weedy thing at the best." I have no further note of its 

 occurrence. A native of North America.
