Bicknell : Ferns and flowering plants of Nantucket 483 



appear pure white I have invariably found that some slight brown- 

 ish tinge was revealed to close inspection. 



RVXCHOSPORA GLOMERATA (L.) Vahl. 



Very common in low grounds. 



Rynchospora alba (L.) Vahl. 



Frequent or common in sandy swamps and cold bogs, often 

 growing in wet sphagnum. 



* Rynchospora Torreyana A. Gray. 



First found on Nantucket, August 30, 1904, between 'Sconset 

 and Tom Never's Pond, scattered here and there along a damp, 

 sandy, nearly obliterated cart-path through an open growth of low 

 vegetation, its flower-clusters in all stages of development up to 

 full maturity. On September 15, 1897, it was found in consider- 

 able abundance over a damp sandy level south of the 'Sconset 

 road near the seventh mile-stone, about a mile from where it had 

 been found three years before. Here it was associated with Drosera 

 filifonuis, Blephariglottis Blephariglottis, Lycopodiu m alopeatroidcs, 

 a nd other interesting plants.
