Var. 8, cochleatum ; bi-tripinnate often very large, primary 

 divisions sometimes long-petioled or in other words the rachis 

 is branched, sori large so that they cover and conceal the 

 whole under side of the pinnules, involucres remarkably 

 large very convex their margin singularly inflected (possibly 

 diseased). N. cochleatum, Don, Prodr. Fl. Nep. 



I shall give other synonyms under the following localities, 

 chiefly derived from my own herbarium. 



Ilab. Europe. Tliroughout Great Britain and Ireland, and equally common 

 throughout Europe. The \nr.paleaceum of Mr. Moore, of wiiich the rachis is richly 

 clothed with spreading, subulate, long, slender, glossy scales, a])proaches in form, 

 })inna;, and segments, the var. $, hut is smaller and not at all coriaceous. From 

 Pembrokeshire and from Surrey, Mr. Moore, from Dunkeld, Mr. Black, and from 

 Somerset, Mr. Clarke, have sent me siiecimens of var. 7; and I have the same 

 from the Caucasus, and the South of Russia and Persia, under the name of Aspid. 

 affine, Fischer, mss. Asia Minor, var. (8, Forbes. 



Africa. The var. paleaceum, more closely resembling var. /3, was found in 

 Madeira by the late Dr. Lemann, and is named, in my herbarium, N. affine, Lowe 

 (mss.) ; but far more common there is var. 7 (A. elongatum, Stv.). It is equally 

 abundant in Canary, Azores, Webb, and others (Asp. Canariense, A. Braun), and in 

 the Cape de Verde, Forbes. Island of St. Thomas, alt. 6000 feet (quite our var. 

 /3). Cape of Good Hope, var. 7, Doom-kop, Burke, var. 8 (quite tripinnate, 

 closely approaching N. inaquale). Abyssinia, Schimper, n. 6, and w. 523. Tro- 

 pical West Africa : Maraml)alla, alt. 2500 feet. Kirk, Zambesi Mission, var. 7. 

 Bourbon, var. 7, tripinnate {in Herb, iiostr.) ; also in Mauritius, Bouton. 



North Amp;rica. Woods, Monterrey in California, Hartweij, n. 2039, com- 

 mon form ; but this does not appear to have been found anywhere in the United 

 States or in British North America,* from the Atlantic to the Pacific, but now 

 that 1 have seen more of the varied forms of this species from other countries, I 

 am disposed to refer my N. Floridanum {Fil. Exot. t. 99) to it. It partakes of 

 the common form in the inferior and sterile portion, whilst the superior and fer- 



* Kunze, however, says {Sillim. Journ. 2d. ser. v. G. ]?. 83), " I have seen the 

 (rue Filu-mas from Newfoundland."
