NOTES FROM MY HERBARIUM. 
E. F. WILLIAMS. 
DURING a recent examination of my herbarium Prof. Fernald 
noted some data which at his suggestion it seems desirable to put on 
record, and I therefore send them to RHODORA. 
Potamogeton Vaseyi Robbins was collected in a bayou of the Con- 
necticut river at Hanover, New Hampshire, in young fruit and with 
floating leaves on July 12, 1910. The fruiting form with floating 
leaves is given as rare in the 7th edition of Gray’s Manual. It was 
abundant at this station. 
Solidago macrophylla Pursh, var. thyrsoidea (Mey.) Fernald, col- 
lected July 30th, 1907, on Mt. Moosilauke, New Hampshire, a new 
station for New England for this mountain variety. 
Artemisia pontica L. with fine flowering spikes, collected on old 
wharves at Portland, Maine, Aug. 3, 1910. This introduction from 
the Old World ought to be admitted to the Manual. I have it from 
Walpole, New Hampshire, collected July 28th, 1901, and Tewksbury, 
Massachusetts, collected September 24th, 1899, where the station is 
extensive and the plant at last accounts spreading. It has also been 
reported from other stations. This Portland station, however, is the 
first one to yield in my experience flowering specimens, all the other 
collections being of sterile plants. 
Rosa rugosa Thunb. is also a claimant for admission to the Manual. 
I have collected it for several seasons on the beach at Middletown, 
Rhode Island, where it appears to be thoroughly at home. It is 
spreading notwithstanding very adverse conditions. 
Antennaria neodioica Greene, var. gaspensis Fernald, new to the 
United States and to the Manual range, was collected by Prof. J. 
Franklin Collins and myself at Fort Kent, Maine, on July 22d, 1900. 
This plant was named by Mr. Fernald from specimens collected in 
July, 1905, at Tracadigash Point, Carleton, and on Mt. Ste. Anne, 
Percé, both stations in Gaspé peninsula, Province of Quebec, outside 
the Manual range. It will now have to be included in our flora. 
CAMBRIDGE, MASSACHUSETTS.
