Hab. Perhaps the most northern localities recorded for this Fern are given by 

 Ledebour, in ' Fl. Rossica;' Turcomania, in Uralian Siberia, at the river Baker in 

 the Caucasian provinces ; South of Switzerland, Nice, and various countries bor- 

 dering on the Mediterranean, Corsica, Crete, etc. etc. Arabia, Forskal; Abys- 

 sinia, Schimper, n. 1312. S. Africa, east of the Cape, Uitenhage, Zeyher, Dreye, 

 Harvey ; Macalisberg, Sanderson. Persia; Gurril, Dr. Fischer. India, in va- 

 rious locaUties, and generally exactly the European form ; Nilghiri, Maclvor, Dr. 

 Schmidt; Calcutta to Nepal, Wallich; Simla, Col. Bates ; Mussoorie, Dr. T. 

 Thomson, Jacquemont ; Punjaub, Jacquemont ; Boutau, Booth (fertile pinnae an 

 inch broad) ; Sikkim-Himalaya, 6000 feet, Ratery Valley, and Khasia, Hooker 

 and Thomson; Kumaon, 3000 feet, Strachey and Winterbottom ; Eastern Nepal 

 (small state of the plant, with generally few and subdigitate pinnje, approaching 

 our Pt. Tamburii, but the pinnules are spinuloso-serrate), Wallich. Isle Bourbon

Var. stenophylla, N. India, Nepal, Kumaon, Wallich, Strachey and Winter- 

 bottom; Ghalti and near Salokor, Edgeworth ; Khasia, Griffith (small). Philip- 

 pine Islands, Cuming, n. 283 (taller and ai)proaching the ordinary form of the 

 species, but pinnae narrower). — Under this species synonyms might be multiplied 

 and further localities added, but enough has been given to show that the species 

 is widely dispersed, and hence it is that, as I have often had occasion to observe, 

 new species have been made under an impression that an American or Indian 

 species must be distinct from a European one. Considering how widely it is 

 dispersed, it is remarkable to find it assume so few very distinct forms. Our only 

 fear is that we ought to have united some of the following species with it.
