portion of this common (several acres), and associated with its

Down. 



One of the earliest Carices to flower. By the third week in June I 



have found the seeds all shed and the spikes withered ; but the large

rhizome serve, when flowers and seeds are gone, to distinguish it from its 



associates, C. pilulifera and C. prcecox.
