1 In the herbarium of the New England Botanical Club there is a specimen of 
Schizaea pusilla Pursh, distributed by Addison Brown and labelled as collected in 
Rhode Island by J. W. Congdon. When questioned in regard to it in 1907, Mr. 
Congdon wrote that he had never collected this species in Rhode Island or any where 
else, but that various specimens of it from New Jersey had passed through his hands 
in the course of exchanges and that one of these had, no doubt, got wrongly labelled.
