and the pinnules are half upright; in G. flagellaris the angles in 

 the forks are often nearly or quite a right angle, and the pinnules 

 spread horizontally. The habit of G. flagellaris is very much 

 that of G. linearis Clarke {G. dichotoma Hook.), but the latter is 

 sharply distinguished from all other Gleichenias by the branches 

 being leafless below the fork. 



The nomenclature of this fern presents some difficulties, but we 

 have neither the herbarium-material nor the library at our dis- 

 posal to be able to settle the difficulty. Gleicheiiia flagellaris 

 Spr., and G. Icevigata Hook., are united in Hooker's " Synopsis 

 Filicum," and kept distinct in C. Christensen's "Index Filicum." 

 In van Rosenburgh's quite recently published "Handbook of the 

 Malayan Ferns " the author adopts Hooker's name G. Icevigata^ 

 and adds (?) G. flagellaris Spr., as a doubtful synonym. In a 

 footnote he explains that G. flagellaris Spr., which has the under- 

 surface very glaucous, is probably another species very near our 

 plant, but not Malayan. It seems that the typical G. flagellaris 

 is a native of Mauritius, and the Malayan form is G. Icevigata, 

 united later with G. flagellaris', if this inference is correct, the 

 fern in question should be called G. laevigata Hook., if G. flagel- 

 laris is regarded as a distinct species, but the latter name has 

 priority if they are united. 



Angiopteris evecta Hoffm. 



Burringbar, Tweed River district (B. Harrison; May, 1909). 



No specific New South Wales locality for this common tropical 

 fern has been previously recorded, so far as we know. Mueller, 

 in his Second Census of Australian Plants, gives " N.S.W., Q," 

 as its habitat; and, as it is not a native of either Norfolk Island 

 or Lord Howe Island (included by Mueller in his "N.S.W." 

 records), Ave must infer that he knew of a specific locality in New 

 South Wales, but we cannot find any reference to this locality in 

 his publications, and Prof. Ewart informs us that there are no 

 New South Wales specimens of Angioptei^is evecta in the 

 National Herbarium, Melbourne.
