Collomia linearis Nutt. 



Along the railroad at Lime Lake, Cattaraugus co., where it is plen- 

 tiful, bat doubtless introduced from the west. July. F. E. Fenno. 



Euphorbia nicaeensis All. 



Various places along the Susquehanna river in Tioga county, and 

 abundant about Barton. Introduced but well established and con- 

 sidered a vile weed. May. F. E. Fenno. The name here used is 

 applied to this plant in the Manual and in Illustrated flora, but in 

 Norton's revision of the American species of the section T i t h y m a - 

 his of the genus Euphorbia, Euphorbia lucida Waldst. 

 & Kit. is taken to be its proper designation. 



Convolvulus japonicus Tkunb. 



Roadsides and waste places about dwellings. Elizabethtown and 

 Claryville. July and August. This is an introduced plant, a double 

 flowered form of which is cultivated for ornament and sometimes 

 escapes from cultivation. 



Heteranthera dubia (Jacq.) MacM. 



Muddy shore of Allegheny river near Olean. August. A small 

 form of which only one specimen was found in flower. F. E. Fenno. 



Cyperus rivularis Kunth 



Near Patchogue. August. This species closely resembles C . 

 d i a n d r u s Torr., from which it may be distinguished by its shorter 

 styles, more narrow and shining spikelets and more slender habit. 



Panicum waited PursJi 



Ditches and wet places. Cayuga marshes. W. R. Dudley. Not 

 rare. Formerly considered a variety of P.crus-galli L. and 

 reported under the name P.crus-galli hispidum Torr. 



Panicum linearifolium Scribn. 



Dry soil. Little Stissing mountain, Dutchess co. July. This 

 grass closely resembles P. depauperatum Muhl., from which it 

 is separated by its pubescent spikelets and small secondary panicles 

 near the base of the stem.
