52 Thirty-first Report on the State Museum. 



Hypericum pyramidatum Ait. 



Near "Ball's Head," Rensselaer county. Wibbe. 



Elatine Clintoniana Pk. 



Having recently reexamined and compared the seeds of this plant and E. 

 Americana, I find that the seeds vary somewhat, and that the differences 

 which I formerly observed vanish when many specimens are compared. I 

 am, therefore, of the opinion that the former is merely a dwarf state of the 

 latter. 



Impatiens pulta Nutt. 



A white-flowered form. Irondequoit. Gf. T. Fish. 



Rhus typhina L. 



Apparently a hybrid between this and R. glabra. Fort Edward. M. W. 



Vandenburg.

LONICERA CJERULEA L. 



Plentiful on the borders of Lake Tear. Mount Marcy. 



Nardosmia palmata Hook. 

 Guilderland, Albany county. 



SOLIDAGO LATTFOLIA L. 



Apparently a hybrid between this and S. ccesia. Fort Edward. Van- 

 denburg. 



SOLIDAGO RIGIDA L. 



Plentiful along the Harlem railroad at Copake. This is probably one of 

 its most northern stations. 



HlERACIUM AURANTIACUM L. 



Meadows near Oswego. Wibbe. This plant appears to be rapidly spread- 

 ing over the State. 



Vaccinium corymbosum L. v. atrococcum Gr. 

 This strongly marked variety occurs in Sandlake. 



Atriplex hastata L. 



Spreading and becoming rather common about Albany. 



Montelia tamariscina Nutt. 



Shore of Lake Champlain at Ticonderoga. 



Ulmus Americana L. 



A corky-bark form of this tree occurs in the vicinity of Albany. The 

 corky portion is in layers parallel to the surface of the trunk. I have not 

 observed it on the branches.
