 Paget Marsh. At the time of the preparation of the "Challenger" 

 report, this interesting species was known only from a specimen in 

 the Sloan Herbarium at the British Museum, and as no subsequent 

 collections had been made up to that time, Prof. Hemsley expressed 

 some doubt as to whether the species described by him was really 

 collected in the islands. Our rediscovery of it in September, 1905, at 

 what is likely to be the original locality in Paget Marsh, settles the 

 correctness of Sloan's label beyond a doubt. The species appears 

 restricted at the present time to this one locality, where, however, 

 it is growing in some abundance. 

 Carex albolutescens Schwein. 



S. B., No. 702, May, 1909. Eastern end of Devonshire Marsh. 

 Abundant. Not observed elsewhere.
