Bicknell : Ferns and flowering plants of Nantucket 485 



a 



rather more mature than the narrow-spiked form at the same 

 date. In a very wet place southwest of Sachacha Pond is a 

 large patch of a form somewhat intermediate between its two ex- 

 tremes but apparently best referred to a small-spiked state of the 

 broader-spiked form. Here the spikes were still green as late as 

 September 19, 1904. 



In their extreme states the broad-spiked and narrow-spiked 

 forms of this plant present rather striking differences and appear 

 quite distinct, but these differences are subject to a most confusing 

 interchange in whole or in part, so that it is sometimes difficult to 

 assign specimens to either form. My own observations on Long 

 Island make it appear probable that the narrow-spiked form is a 

 state which sometimes reflects conditions of greater shade, and 

 gain expresses a modified development through a drying up of 

 the soil before the plant has reached its natural maturity. Con- 

 tnbutory to this view is the fact that the narrow-spiked form seems 

 to be quite generally infertile. 



Carex comosa Boott. 



Rather common in wet places. Spikes just appearing June 1 5 ; 

 st| U fresh at the middle of September. At Watt's Run with 

 unusually narrow spikes simulating C. pseudo-cypcms. 



*Carex vestita Willd. 



At a number of rather widely separated localities : Trot's 

 Swamp ; Millbrook Swamp ; Quaise ; Polpis ; Tom Never's Pond 

 j™ d at several places about the borders of the swamp. In full 

 0w er June 10 ; no perigynia remaining August 7, 1906. Often 

 ° CCUrs in wetter places than is usual for this species, sometimes 

 CVen growing in wet sphagnum. 



Carex Walteriana Bailey. 



Occurs rather sparingly in a small bog south of the roadside 

 ° u ntain erected by the Commonwealth of Massachusetts to mark 

 e birthplace of Abiah Folger Franklin, mother of Benjamin
