brownish-green in color and have two or three faint veins each side of 

 the midrib. These are connected by transverse veinlets. The stems 

 were not at all branched but in some instances they had sent out runners 

 from the base and had thus given rise to new plants. Neither petiolate 

 nor floating leaves were seen. The dry fruit has a deep impression or 

 pit on each side. This is Potamogeton obrutus, Wood. 



Eleocharis quadrangulata, R. Br. " Paddy lake," South Scriba, 

 Oswego county. Wibbe. This is a rare plant. In the Manual the 

 outlet of Oneida lake is given as a station for it and in the Beck 

 Herbarium a specimen is labeled N. Salem pond, Westchester county.

Triticum violaceum, Hornem. Rocky places and mountain preci-. 

 pices. Stissing mountain and Adirondack mountains. June and July 

 I have seen no specimens with purplish or violet-tinged spikes. The 

 lower sheaths are sometimes slightly hairy or downy. The awns vary 

 in length and when long they sometimes curve outward. 



Nitella ?opaca, Ag . Edmonds ponds. July. The specimens are 

 referred to this species because of their dioecious character. Their 

 general appearance is remarkably like that of N. flexilis. But few 

 fertile plants were seen.
