(LZ. F. Ward, no. 484): Ipano, Lake Pend d’Oreille (Sandberg, Mae- 
Dougal § Heller, no. 751). A plant confined in the East to arbor- 
vitae swamps at low altitudes, and in its tall lax habit and very distant 
spikelets hardly suggesting the dwarf alpine C. capillaris with approxi- 
mate spikelets. Somewhat similar specimens in the Gray Herbarium 
from Salzburg, Austria, suggest that the same form may be present in 
Europe.
