 Moench, Ilysanthes dubia (L.) Barnhart, etc. 



A list of the ninety-four species collected is appended 

 which is to be regarded as merely indicating those which 

 were most abundantly represented or most conspicuous and 

 therefore as characteristic of the locality. Probably the only 

 one in the list which merits any special mention is Corema 

 Conradii Torr., which apparently has not been reported from 

 Provincetown since the time of Thoreau's visit, in 1849, when 

 he found it near the lighthouse of Truro, and says : " I saw it 

 afterwards in Provincetown." It was also collected at Truro 

 in July, 1886, by J. H. Redfield, according to memoranda 

 kindly transmitted to me by Dr. B. L. Robinson, of Harvard 

 University.
