Latifolio-imbricatum, Lotve. (Figs. 368 and 369.) — Raised 

 from spores by myself in 1863. A handsome distinct variety, 

 evidently a sport from latifoUum. Fronds oblong-lanceolate. 

 Pinnae in sterile fronds crowded, in fertile fronds the basal half 

 distant. Pinnules conspicuously brief-stalked almost to apex of 

 frond, ovate, imbricated very regularly from the middle upwards; 

 fringed with small teeth. Sori almost submarginal. Pinnules 

 lobate. On either side of the rachides are small oval openings 

 between each pinnule from the base to the pinnatifid apex.
