2. Commelina nudiflora L. While this is apparently a widely 

 distributed plant the only specimen in the collections is from 

 Inwood, N. Y. City. According to general works it should be 

 found from New Jersey southward, etc. Is it found on Long 

 Island ? 



PONTEDERIACEAE 



1. Pontederia cordata lancifolia (Muhl.) Morong. While the 

 common pickerel-weed is exceedingly common everywhere, this 

 lanceolate leaved form comes only from Green Pond, N. J. 

 General works say of it " Ont. to N. J.," etc. Has it ever been 

 found outside of this one pond in New Jersey? 



2. Heterantliera reniformis R. & P. All the specimens in the 

 collections are from New Jersey and Pennsylvania, The exclu- 

 sion of this plant from the Hudson valley and Connecticut is 

 obviously untrue but specimens at hand do not show its distri- 

 bution outside of New Jersey and Pennsylvania. 



JUNCACEAE 



1. Jiincus gymnocarpiis Coville. Its general distribution is 

 given thus, " In swamps, mountains of Schuylkill and Lebanon 

 counties, Penn." The only specimen in the collections is from 

 the former county. Is the plant localized in the hills near this 

 region or may it be looked for elsewhere ? 



2. JitJicus Balticiis Willd. So far as the specimens show this 

 plant grows only on Staten Island. With a general range of 

 from Labrador to southern New York, is this delimitation, as 

 shown by our specimens, reasonable ? 



3. Jmiciis Roemerianus Scheele. Through an early though 

 still current error, the plant is credited to New Jersey. No 

 specimens can be found which come from north of the Carolinas, 

 and as an element in our local flora the plant may be ignored. 



4. Jiincus maritimus Lam. The only station in the New 

 World for this plant is Coney Island, New York City. Years 

 ago it was reported from New Jersey but no specimens are ex- 

 tant. How far from Coney Island has the plant spread, if at all ? 

 Has any one specimens from New Jersey? Staten Island ?
