 side ones rounded or nearly truncate at the base. Sori 3-5

 glabrous, nearly black. End segments cuneate ; lateral tra- 

 pezoid, \ in. long, cuneate. Sori orbicular, 3-4 to a segment,

43. A. excisum, Kunze. A. Pacotti, Hort. and A. Weigandii, 

 Moore, in Card. Chron. 1883, II, 748, are forms of garden 

 origin, probably derived from this species. 



45*. A. Wagneri, Mett. (A. decorum, Moore). A. elegans, Moore, in 

 Card. Chron. 1886, I, 200; A. cyclosorum, Moore, in Card. 

 Chron. 1887, I, 547; and A. Oweni, Moore, in Gard. Chron. 

 1887, 1, no, are forms of garden origin nearly allied to this 

 species. 



46. A. tenerum, Sw. A. Lathomi, Gheisbreghtii, scutum, Far- 



leyense, Victoriae, Bausei, rhodophyllum, and princeps, 

 of gardens, are probably all of them derived from this species. 

 46*. A. Collisii, Moore, in Gard. Chron. 1886, I, 68 1. A form of

 tenerum and cuneatum.
