482 Bicknell : Ferns and flowering plants of Nantucket 



Common. Subject to much variation in the form of the in- 

 florescence and in the time of flowering. A late-flowering form is 

 tall and stout with stiff, much elongated inflorescence, often more 

 foliaceous-bracted than in the earlier-flowering form and sometimes 

 wholly green and immature in September when the latter growing 

 with it is fully ripe ; the base of the involucels is variable in color 

 but is often a dull black. _ 



Forms answering the description of var. peliu 

 frequent, intergrading variously with the more common 



form. 



The state of the plant with congested inflorescence (var. condensate 

 Fernald) was observed several times in its extreme phase ; certain 

 specimens appeared to represent a congested state of the var. pdms 

 rather than of the typical form, which is also subject to the same 



variation. 



* Scirpus pedicellatus Fernald. 



Infrequent. Typical examples were collected, as well as o 



ypennus as to be only arbi- 



trarily separable. 



* Eriophorum viride-carinatum (Engelm.) Fernald. 



Watt's Run Bog, June 15, a scattered group of strongly d<

Eriophorum tenellum Nutt. 



Rather common. Long Pond ; Maxcy's Pond ; Waq"W ^ . 

 Pond ; Pout Ponds and ponds to the eastward in Shaw kenl ° ^ 

 several sphagnum bogs west of Sachacha ; Watt s un ,

Eriophorum gracile Koch is admitted in Mrs. (Jwe /W/«'« 



but as this species was formerly often confused wit 

 the record should now be substantiated.

Eriophorum virginicum L. 



Common in wet bogs generally and locally abun • ^ 

 The form with the heads white or nearly so, P re ^ ool ma y
