1904] Sanford, — Saururus cernuus in Rhode Island j'j 



I first found this plant in 1895, growing among stones by a road- 

 side in Pittsford, Rutland County, Vermont. The specimens formed 

 a large clump. Nearby grew D. marginalis and a form of D. spinulosa. 



In 1 90 1 the hybrid clump was transplanted to Mr. George E, 

 Davenport's garden in Medford, Massachusetts, where it has remained 

 since. It has produced mostly smaller fronds in the new location than 

 in the old, but apparently has lost none of its peculiar characteristics 

 at any time. 



Type specimens are in the herbarium of the New York Botanical 

 Garden. 



I am greatly indebted to Mr. Davenport for his kind assistance in 

 the study of this fern. 



Note by Mr. Davenport. — Since Miss Slosson's fern was trans- 

 planted to my garden in 1901 it has increased to five plants from 

 young crowns growing out from the main rootstalk. One of the new 

 plants was sent to Miss Slosson and another has been reserved for 

 the Botanical Garden at Cambridge. During the past two seasons I 

 have pressed all available fronds from the original plant and speci- 

 mens of these will be deposited in the Gray Herbarium, the Herbarium 

 of the New England Botanical Club, and the Davenport Herbarium 

 of the Massachusetts Horticultural Society. In 1893 Mr. Raynal 

 Dodge collected some specimens which he regarded as of hybrid 

 origin between Nephrodhwi spiniilosum and JV. tnarginak. "^hese I 

 have had under examination for some time, but in the absence of 

 the rootstalk, and other necessary data, I have not been able to satisfy 

 myself as to their exact status. They differ greatly, however, from 

 Miss Slosson's fern. — G. E. D.

The Range of Saururus cernuus extended into Rhode 

 Island. — In August, 1902, while exploring the meadowlands stretch- 

 ing from Adamsville, Rhode Island, to the ocean shore. Judge 

 Benjamin Cook, Jr., ran across some plants, which were at once 

 recognized as Saururus cernuus, L. One year later, July 29, 1903, 

 Mr. Cook and the writer visited the locality and found the plants at
