Jolium which he had collected on the sandy flats of New Jersey. 
NOTES ON MAINE PLANTS. 
ELMER D. MERRILL. 
THE following notes on Maine plants may be of interest to students 
of the flora of that state. Several of the plants enumerated below 
have never before been listed from the state, and others reéstablish 
localities for species which have been previously reported, but for which 
the locality has been lost. 
The few species listed from Mt. Ktaadn are added more especially 
because of the interest of the locality. During a trip there in Septem-

region were collected, which have previously been reported by Scribner,

collectors.

low water and partly emersed. Three Ponds, Mt. Ktaadn, September, 
1898. Altitude about 2,000 feet. 
Oryzopsis melanocarpa Muhl. Growing abundantly on rocky wooded 
hillsides. East Auburn, August, 1898. Not previously reported from 
the state.

Panicum tsugetorum Nash. Pastures, East Auburn, July, 1898.

July, 1898. 
Polygonum Zuccarinii Small (P. cuspidatum, Sieb. & Zucc.). Waste
