think it will be better treated as a variety than as a mere form, as 

 the entire plant shows the peculiar character, which is again repro- 

 duced in its offspring. It has apparently been established for some 

 years, having attained large proportions and, fortunately, there 

 appears to be little or no danger of its being disturbed, as the sur- 

 rounding woods are safe-guarded from trespass. 'I'he plant is cer- 

 tainly unique in every way and entitled to recognition. 1 therefore 

 submit the following description : — 



Nephrodium sfinulosum, var. Concordianum, n. var. (Pur- 

 dik's Concokd Nkphrodiu.m.) Original plant large, with matured 

 fronds two and one-half to three feet in height. Rootstock as in the 

 species ; crosiers densely clothed with rich brown scales ; stipites 

 one-fourth to one-third tiie length of the whole frond, greenish- 

 stramineous in the early stages but at length turning to a warm 

 brownish tone, channeled along the face, rounded at the back ; scales 

 at base broadly ovate-acuminate, dark brown with deeper centres, 

 the upper pale and intermixed with narrower linear scales and chaff; 

 laminae one and one-half to two feet long, correspondingly broad, 

 narrowing from below the middle upward to an acuminate apex, 

 tripinnate throughout, the inferior pinnules on the low^ermost pinnae 

 of the larger fronds two inches long and pinnate with pinnatifid or 

 deeply lobed oblique divisions ; segments distinct, narrowly angular, 

 about one-eighth of an inch wide, sharply aculeate, the base so 

 narrow as to appear stalked (in some cases really so) ; rachises 

 scaly throughout with small pale scales and chaff ; venation pinnate ; 

 sori below the apex ; indusia and surfaces minutely glandular. 



Habitat : rich swampy woodland. Concord, Massachusetts, autumn 

 of 1902, //. A. Pnrdie 6- Win. Brewster; August, 1903, H. A. 

 Fiirdie &^ G. E. Davenport. 



As the discoverer of this interesting fern protested with his usual 

 modesty against my associating his name with it, I have decided to 

 dedicate it to Concord. Type specimens from the original plant will 

 be deposited in the Gray Herbarium, the Herbarium of the New^ 

 England Botanical Club, and the Davenport Herbarium (Massa- 

 chusetts Horticultural Society). 

 Medkord, Massachusetts.
