happily, the work had been already in great part done for us, in the 

 light of present knowledge, by the veteran cryptogamist of the Con- 

 necticut valley, Charles C. Frost, Esq., of Brattleborough ; to whom we 

 thus owe at once the Mosses, Liverworts, Charaeese, and Fungi. 



The foreign, whether or not naturalized, plants of a Flora, though to 

 a considerable degree fluctuating aud uncertain, are by no means of 

 least interest to the botanist ; and some care has been taken to reckon 

 them pretty fully. When this region was first settled much good grass 

 land was found in the Indian clearings; and "we may safely conclude 

 that there were green meadows " and " grassy upland in scattered, open 

 woods . . . in this Xorwottuck valley " (Judd Hist. Hadley, p. 105). 

 But it was not long before English Grass was grown. John Pynchon, 

 Esq., of Springfield, had already several acres of this in 1658 (Judd, 

 p. 370). And Josselyn, writing in 1672, has an interesting list of " such 

 plants as have sprung up since the English planted and kept cattle in 

 Xew England" (Xew England's Rarities, p. 85) that is, as were brought 

 in, in good part, with the English grass-seed. A considerable number 

 of our introduced plants thus probably came in early; while others, 

 whether in part appearing and disappearing before, are no doubt later 

 additions. It will be interesting to ascertain what we can of the arrival 

 among us of these strangers; and, as further accessions of the same 

 sort are to be expected, to take note of their first appearance. And the 

 history of even long- established denizens appears to be not wholly 

 beyond our reach. Thus the Daisy (Leucanthemum, Tourn., — Great 

 Daisy of the old botanists) is said to have been introduced, about sixty 

 years ago, by a Rhode Island man, Cundall by name, who brought seed 

 here for the purpose of planting for horse-feed ; for which the plant was 

 recommended (Inf. of T. Buffum) a story implying that it was at least 

 not conspicuous before. Ribwort (Plantago lanceolata, L.) now frequent 

 everywhere, appears to have been recognized by Dr. Hitchcock in South 

 Amherst only, in 1829. And Rudbeckia hirta, becoming every year 

 more common, had, it is scarcely doubtful, its first introduction with 

 Western grass-seed, or between twenty and thirty years since; seed 

 before then being got from Yermont and Canada (Inf. of G. Cutler). 

 The plant was unknown to Hitchcock in 1835 (Catal. Mass.) as to 

 Dewey (1840) but was recognized as occurring in Xew England in 1856, 

 by Gray. Other western species may well be expected to reach us in 

 the same way. The present catalogue will afford the first date, of some 

 introduced plants no doubt which may not hold their ground, as of
