198 Underwood : American ferns 



Other specimens of the same were collected by the writer in 1890 

 near Cambridge, Massachusetts, as noted in our collections by Dr. 

 Philip Dowell, who collected the same thing on Staten Island, 

 N. Y., in 1904. The species appears to stand on about the same 

 basis as D. Boottii. Until the present turma of varieties, now 

 connected with the variable D. spinulosa, can be made the subjects 

 of more serious field study than they have yet received in this 

 country, this name may well stand. 



Dryopteris stipularis (Willd.) Maxon in herb. 



Aspidium stipularis Willd. Sp. PL 5: 239. 18 10. (Type 

 from Martinique, citing Plumier, pi. 23.) 



Florida : Miami, A. A. Eaton. Specimens seen in the U. S. 

 National Museum. 



Dryopteris ampla (H. & B.) Kuntze, Rev. Gen. PL 2: 812. 



1891. 



Poly podium amplum H. & B. in Willd. Sp. PL 5 : 207. 18 10. 

 (Type from Caripe, Venezuela.) 



Florida: Between Cutler and Longview Camp, 1903, Small 

 & Carter 834, 833. Already reported by Mr. A. A. Eaton (cf. 

 Fern. Bull. 12 : 46). 



This species forms a short caudex like a tree-fern ; the pecu- 



* 



liar mass of cinnamon-colored matted scales at the base of the leaf- 

 stalks is strikingly characteristic. 



Meniscium reticulatum (L.) Schkuhr, Krypt. Gewachse 5. //. 5- 



1 804. 



Poly podium reticulatum L. Syst. Nat. ed. 10. 2 : 1325. 1759- 

 (Type from Martinique and based on Plumier's figure.) 



Dryopteris reticulata Urban, Symb. Ant. 4 : 22. 1903. 



Florida : Alapattah near Miami, 1903. A. A. Eaton 779- 

 Already reported by Mr. Eaton (cf. Fern Bull. 12 : 46). 



The genus Meniscium, established by Schreber in 1791, is well 

 characterized by its venation and sori, the latter being linear and 

 naked and borne on cross veins connecting the lateral parallel 

 veins which extend from the midribs to the margin forming a series 

 of similar areolae. The validity of the genus was never questioned 

 until Diels, in placing it in its proper tribe, in our judgment went 

 too far by uniting it with Ncphrodiiim, from which it has more 

 recently been transferred to Dryopteris by Professor Urban.
