` CERTAIN RAILROAD WEEDS or NORTHERN NEW HAMPSHIRE.— 
On 24 August, 1908, while making a trip over:the Baldcap Range 
from Shelburne into the township of Success, New. Hampshire, Mr. 
A. H. Moore and the writer discovered, in the latter township, on the 
gravelly bed of an abandoned lumber-railroad, a flourishing colony 
of Gnaphalium sylvaticum L. The. railroad has not been used for 
years, and this locality, itself on a branch line, is some miles from 
any settlement, the nearest at present being Berlin, five or six miles 
distant. unt 
Various plants of interest have appeared along the Grand ‘Trunk 
Railroad in northern New Hampshire. Most prominent is Euphor- 
bia hirsuta Wiegand, which has formed large mats along the track 
in Berlin and Gorham, and in September is very conspicuous from 
the orange color of its stems and foliage. Ambrosia psilostachya DC. 
grows along the Grand Trunk near Berlin, and there are two clumps 
of Artemisia ludoviciana Nutt. along the Boston and Maine tracks 
in the same town. Euphorbia Helioscopia L., Chenopodium glaucum 
L., and Salsola Kali L., var. tenuifolia G. F. W. Mey. are also of local 
occurrence in Berlin.  Polygonella articulata (L.) Meisn. may be 
traced along the Maine Central up through Crawford Notch to Craw- 
ford's, where it appears sporadically, and still farther north, on the 
Boston and Maine, near Appalachia Station in Randolph, it is thor- 
oughly and abundantly established. Specimens of these plants are 
preserved in the writers herbarium. — ARTHUR STANLEY PEASE,

ADDITIONAL NOTES ON PLANTS OF CHESTERVILLE, MaArNE.— The 
most noteworthy plants found in this vicinity during the summer of 
1908 were discovered in the month of June by Miss F. J. Keyes and 
were as follows. 
Habenaria bracteata (Willd.) R. Br., in a swamp on Zion’s Hill, 
near North Chesterville. 
Arethusa bulbosa L., in a bog bordering оп Lock's Pond, near 
North Chesterville. According to the present knowledge of the

range a few miles farther north.
