X._ CATALOGUE OF PLANTS, 

 GROWING WITHOUT CULTIVATION. 



In the arrangement of the following Catalogue, I have followed, — as the latest 

 and most accurate, — the Natural System of Prof. Lindley, as adapted to North 

 American Plants by Prof. Torrey. The sources from which I have derived ma- 

 terials for constructing this list, are mainly the following ; First, Professor Bige- 

 low's 1 Collection of Plants of Boston and its vicinity.' (1824.) Secondly, ' A 

 Catalogue of Plants Growing without cultivation in the vicinity of Amherst 

 College;' (1829,) with such additions and corrections as I have been able to 

 make since the time of its publication. Thirdly, Professor Dewey's Catalogue 

 of Plants found in the County of Berkshire, (1829,) inserted in the History of 

 Berkshire. Fourthly, the manuscript communications of Thomas A. Greene 

 Esq. containing a notice of such plants as he has discovered in the vicinity of 

 New Bedford and on the Island of Nantucket, not mentioned in the last edition 

 of Bigelow's ' Florula Bostoniensis.' 



To the Latin or scientific names of the plants, I have attached their common 

 names, whenever I could ascertain that they have excited attention enough to re- 

 ceive a common name. But it will be seen that comparatively few of our plants 

 have received common names. 



When a capital A. is attached to a species, it implies that the plant grows in 

 the vicinity of Amherst : B. implies that it occurs in the vicinity of Boston: N. 

 B. that it is found in the region around New Bedford: and B — e that Berkshire 

 County is its place of growth. In other cases, especially where the species is 

 very rare, the name of the town where it occurs is mentioned. When no local 

 designation is annexed, I have reason to suppose that the plant may be found in 

 any part of the State of considerable extent. In some of the flowerless plants, 

 however, there is an exception to this remark ; as will be mentioned under Mus- 

 coideae. 



In reducing our plants to the Natural Orders I have received the assistance of 

 Dr. John Blodget of Amherst.
