been found recently at various points along the northern sea-board, — 

 in New Jersey, on Long Island, and in 1903 near Fall River, Mass- 

 achusetts. At its only recorded New England station, in a field near 

 Fall lliver, its discoverer, Mr. Sanford^ considered the plant an intro- 

 duction, derived from cotton waste. At Barrington, on the other 

 hand, there is nothing except the proximity of a country-road to sug- 

 gest the introduction of the plant, which is as apparently indigenous 

 as the various ferns, the Rhexia, and other coastal plain plants of the 

 region. 



BiDENS DiscoiiiEA (T. & G.) Brittou. This distinctive plant of 

 the coastal plain is probably common in Rhode Island as it is in adja- 

 cent Massachusetts and portions of Connecticut. It was found in 

 the Barrington swamp, growing commonly on decaying logs and 

 inundated fallen branches; and it was seen, though less abundantly, 

 in a swamp near Jyime Rock in the town of Lincoln. 



The second region visited was in the town of Lincoln. Portions 

 of this township are strongly calcareous, and at one point. Lime 

 Rock, several lime quarries have been opened. Within the town- 

 ship we found many characteristic plants of calcareous .soils which are 

 already known from Rhode Island, but the following eight species, 

 which it is the purpose here specially to note, are ap{)arently additions 

 to the flora of the state.

JuNCUS DEniT.is Gray. In J. L. Bennett's "Plants of Rhode 

 Island," this rush is listed as ,/, acnminatus, var. debilis; but, when 

 preparing the Preliminary List of New England Juneaceae,^ I was 

 unable to verify the report, and saw the species only from Connecti- 

 cut. J. dehilis was found in great abundance with /. Dudlej/i, Par- 

 nassia carollniana, and other lime-loving plants at the border of a 

 pond nciir one of the quarries at Lime Rock. The plants were 

 very luxuriant, often 8 dm. high, with inflorescences L5 dm. long. 

 But the most striking feature of the pbuits is the remarkable devel- 

 opment of autuuHial flowers, such as is known to me only in 

 specimens collected by Ravenel in bSGt) near Aiken, South Caroliuii.
