nist, Mrs. Horner, have been Salvia virgata and Trifo- 

 Uum tomentosum, L., both of Southern Europe. The 

 latter was found ten years ago and from the place of its 

 discovery in Georgetown, is evidently to be added to the 

 list of " Woolen Mill Plants." I am not aware that it has 

 been collected there since. The Salvia appeared this 

 summer, or last, among the seedling flowers of a garden. 



A small-flowered pink, Silene gallica, var. quinque- 

 vulnera, has bloomed for me two years, coming with 

 "wild garden" seed, probably imported from France. 

 Botanists who know our native weeds from strange ones 

 may often get rare things in this way. 



What one might call persistent local attachment is 

 remarkably manifested in some plants. Crocuses and 

 Star-of-Bethlehem ( Ornithogaluni) blossom every year 

 in the dense sward near my house, where they must have 

 been planted twenty-five years ago, perhaps much more, 

 having never in that time been cultivated. Probably 

 some readers can far overmatch these instances. Poly- 

 gonum historta, L., also grows, and often flowers, in the 

 same grass, in spite of having been mown close, once or 

 twice a summer for many years. No doubt it is a relic of 

 some ancient garden. 



In August a white-flowered form of Linaria Canaden- 

 sis, Spreng., was somewhat abundant near Milwood 

 P. O., Rowley. Years ago specimens of "white-fruited" 

 black alder. Ilex verticillata. Gray, were given to the 

 Boxford Natural History Society, from a bush on the 

 land of a Mrs. Cole, of West Boxford. The berries 

 were rather of a yellow ccjlor. One specimen of Hous- 

 tonia purpurea, L., var. longifolia, with white flowers, 

 was also brouglit to our Society from near the center of 

 the town, sown perhaps with grass seed, which so often 

 brings into our soil transient and extra-limital specimens.
