SCIENTIFIC SURVEY. 123 



of the highway, many fine specimens of the interesting species of 

 Juncus, J. Stygius, L. This European species was first detected in 

 the United States, by Dr. A. Gray. He discovered it on the borders 

 of Perch pond in Northern New York, but I have been informed 

 that it is not at all plenty in that locality. Therefore Botanists will 

 be interested to learn of a new and easily accessible locality, which 

 I have, for this reason, been particular in describing. All my spe- 

 cimens of J. Stygius, L., differ, from the specific description, in 

 having a sheathing, filiform leaf clasping the middle of the stem, 

 instead of being " naked above." 



Eriophorum vaginatum, L. common along the " Canada road," 

 so called. Nardosmia palmata, Hook, very abundant in swamps 

 near the Canada line, upon the same thoroughfare. 



Arnica mollis. Hooker. This showy plant is found sparingly, 

 near Moxie Falls, a few miles from the Forks of the Kennebec. 

 It occurs in great beauty and profusion in the vicinity of the cata- 

 ract of Parlin Pond Stream, where its orange flowers are sprinkled 

 by the spray of the falling water. The iridescence of the flowers 

 as they were bathed in the sunlight and the spray, was a spectacle 

 of much beauty, the orange of the blossoms here and there, over- 

 powering the rainbow coloring of the drops of water.

The local distribution of plants is a matter of much interest to 

 the Botanist and Agriculturist. It is not my purpose, however, at 

 this time, to express my crudely formed opinions concerning the 

 laws which have regulated the distribution of plants in Maine, nor 

 to advance any theory in regard to the occurrence of certain 

 species, but to present some facts which have come to my notice 

 during the surveys of 1861 and 1862. Many of the facts were 

 presented in the report of last year, but it is necessary to repeat 

 them in this connection in order to give a clearer understanding of 

 the Flora of the north of the State. It will be seen that I have 

 ventured to divide the upper portion of our State into Botanical 

 districts of considerable extent. That I may place myself right in 

 regard to this subject, let me preface the descriptions of the dis- 

 tricts by some remarks upon plant distribution throughout New 

 England. 



Notwithstanding hundreds of our Phsenogamia are common 

 throughout the length and breadth of New England, I think no one
