Reproduction in Ferns.—Mr. W. T. Thiselton Dyer, in Nature, refers to 
a most interesting discovery recently made by Mr. E. T. Druery. A variety of 
Asplenium filix-femina was discovered upon which the sporangia developed into. 
prothallia bearing antheridia and archegonia. Mr. F, O. Bowen also found an 
Aspidium in which the apex of the pinnules developed in the same way. Apo- 
sporous ferns are looking very strongly towards phanerogams. The same 
writer sums up the progress of discovery in reproduction of ferns in the follow- 
ing concise and instructive way: Observed seedling plants near parents, Ger- 
arde (1597); Sporangia, Cysius (1648); Spores, Cole (1669); Hygroscopic move- 
ments of sporangia, Ray (1686); Raised seedlings from spores, Morison (1715); 
Prothallium, Ehrhart (1788); Germination of spores, Lindsay (1789); Devel- 
opment of prothallinm, Kaulfuss (1827); Antheridia, Niigeli (1844); Archego- 
nia, Suminski (1846); Apogamy, Farlow (1874); Apospory, Druery (1884).
