TWELVE ADDITIONS TO THE FLORA OF RHODE ISLAND. 

 INI. L. Ferxald. 



While visiting in Providence (hiring the latter part of September 

 I had the pleasure of joinino; ^Nliss Margaret H. Grant and Professor 

 J. Franklin Collins on visits to the stations of some rare plants of 

 Rhode Island. Though the object of the excursions was primarily 

 to see certain species already known to botanists of the state, many 

 other plants of interest "\yerc found, among them twelve species and 

 varieties which a search of local lists and notes fails to show as recog- 

 nized in the Rhode Island flora. 



The first place visited was a patch of swampy woods near Nayatt 

 station in the town of Barrington, where, in the lower areas Wood- 

 wardia virginica and W. areolata (W. angustijolia) and Osmunda 

 cinnamomea were sufficiently abundant to be cited as characteristic 

 plants, while in the o])en somewhat drier sandy spots Rhexia vir- 

 ginica and Rynchospora glomcrata were conspicuous species. In 

 this limited region the following plants apparently unrecorded from 

 the state were found. 



AsPiDiUM siMULATU.M Davenport. Abundant in wet woods with 

 Woodwardia areolata. 



Osmunda cinxa:^iomea I.., var. glaxdulosa Waters. Several 

 large plants, among more numerous individuals of the typical gla- 

 brous form of the species, at the edge of the woods. It is interesting 

 that at both the stations already recorded for this noteworthy variety, — 

 Mr. W^aters's original locality near Glen Burnie, in Anne Arundel 

 county, Maryland^ and ]Mr. Saunders's station near Clementon, 

 New Jersey^ — typical 0. cinnamomea and the two Woodwardias were 

 present, and at iSIr. Waters's station Aspidium simulafum as well. 

 All these plants occur in the wooded swamp in Barrington.^ 



Heliaxtous mollis I^am. Abundant in sandy soil by the road- 

 side in one portion of the swamp. This very distinct Sunflower has

3 Mr. W. N. Clute lias recently summarized the two previous records of the habitat of 

 Osmunda cinnamomea, var. glandulosa as "found in dryish situations" (Fern ]iull. xiii. 

 119), although it is not easy to see liovv such a deduction can be made from tlie "low 

 sphagnum woods" of Mr. Waters's account or the "low woods" of Mr. Saunders's record.
