railroad north of Woods Hole, between there and Falmouth. It seems 

 probable that it was a quite recent introduction and the vigor of the 

 plants and the large racemes of hairy pods seemed to point to its 

 establishment in this neighborhood, hut the present season shows none 

 of the original colony remaining. 



Search in the Herbarium of the University of Pennsylvania pro- 

 duced no specimen from the East, and in that of the Philadelphia 

 Academy of Natural Sciences material from the Southern States and 

 one specimen from Illinois were the nearest records. An inquiry at 

 the Gray Herbarium at Harvard University brought the information 

 that the nearest localities which they had represented were Illinois 

 and South Carolina, and the New York Botanical Garden reported 

 nothing from the Central Atlantic or New England States. As there 

 seems to be no published record of this plant from Xew England, this 

 locality then supported the most northeasterly colony of the species 

 yet reported. 



Specimens showing immature pods have been placed in the Herbaria 

 of the Marine Biological Laboratory and the University of Pennsyl- 

 vania. — W. H. Taylor.
