served by Josselyn, voyage, 1670, " a stately tree growing here and 

 there in the valleys." "A buttonwood tree, which measured nine 

 yards in girth," is mentioned by Paul Dudley, writing from New 

 England in 1726 (Phil. Trans., XXXIII, 129, etc.). Not clearly in- 

 digenous along the Atlantic in New England" (Dr. Chas. Pickering, 

 Chron. Hist. PI. p. 961). Probably not a native of Essex county, 

 but introduced from the westward, as suggested by Dr. Pickering. 



JUGIiAlTDACE^. 



(Walnut Family.) 



Juglans einerea, L. (Butternut.) 



Common along walls but not so in forests. Tracy considers it 



an Introduced tree in Lynn. 

 Juglans nigra, L. (Black Walnut.) 



Occasionally cultivated from the western states. We have received 



specimens of the nuts of this tree from Mr. J. C. Peabody of New- 



buryport, gathered in a place near that city where he thinks the 



trees are indigenous, but this seems under careful consideration to 



be hardly probable. 

 Juglans regia, L. (European Walnut.) 



Cultivated in Siilem, to a small extent, where the fruit perfects well. 



The J. regia, noticed in Sangus (Proc. E. I., Vol. II, p. 389), proves 



to be J. nigra. 



Carya alba, Nutt. (Shag-bark Hickory.) 



Common in most towns. 

 Carya tomentosa, Nutt. (Mockek-nut ; White-heart Hickory.) 



Danvers (J. H. Sears). Scarce. This tree is more abundant to 



the south of Boston than in Essex county. 

 Carya porcina, Nuu. (Pig-nut Hickory.) 



Common in most parts of the county. 

 Carya amara, Nutt. (Bitter-nut or Swamp Hickory.) 



Quite common in most towns. Particularly fine trees are to be 



found in Boxford with leaves much more delicate in cutting than 



the usual form, giving the tree a different appearance. 



CUPULIFERiE. 



(Oak Family.) 



Quercus alba, L. (White Oak.) 

 Common throughout the county ; occasionally fifteen to twenty feet 

 in circunifereuce.
