N. Y. Bot. Garden Herb. A specimen from the herbarium 
of P. V. Le Roy, Peekskill, N. Y. Collected in Mass. A. Gray.

however, is but slightly scabrous-strigose, and on the whole glabrous. 
Such a specimen is almost aquatic, and can hardly be interpreted 
* This subsection will probably disappear as the members become 
better known or their terrestrial phases found. It may be that the plants 
have no terrestrial phase, however, and in that case it will remain, unless 
another more obvious method of division seem feasable,
