460 SUMMARY OF CURRENT RESEARCHES RELATING TO 



The same author proposes a new name, Christensenia, for the 

 Asiatic genus Kaulfussia, since this latter name had been already 

 appropriated twice before for genera belonging to Polygalaceas and 

 Compositse. Kaulfussia aesculifolia is now to be known as Christensenia 

 aesculifolia (Blume) Maxon. 



Index Filicum.* — C. Christensen has issued the ninth fascicle of his 

 Index Filicmn, carrying forward the alphabetical enumeration of species- 

 and synonyms from Polypodium Beekleri to Polystklmm aculeatum. 

 The end being thus nigh at hand, he begs subscribers to call his 

 attention to any omissions or errors which they have observed in the 

 work, that he may be able to insert them in the appendix which will 

 appear in the next part, and which will be followed by the remaining 

 sections of the book— the systematic enumeration of genera and the 

 alphabetical catalogue of literature.

Morphology of Australasian MuscineEe.f — K. Goebel continues 

 his studies of the ArchegoniatEe by some detailed observations on the 

 morphology and biology of a number of Australasian Bryophytes, 

 collected by himself some eight years ago. Among the mosses with 

 radial symmetry he discusses Dawsonia, Lyellia^ Dicnemon, Mesotus 

 and Leptostomum, and among the bilateral forms he treats of Eriopus, 

 Pterygophyllum, Gyathophorum, Mittenia, Rhizogonium and Orthor- 

 rhynchium. Dawsonia is regarded as a primitive member of Poly- 

 trichacefe, being less differentiated in the gametophyte ; moreover, in the 

 sporophyte the peristome has always been misunderstood ; it has clearly 

 the same origin as that of other mosses, and is of Polytrichaceons 

 character. The distinction between Nematodontese and Arthrodontete 

 is dropped. The capsule is dorsi ventral, and when mature is horizontal. 

 The affinity of Mesotus to Dicnemon is maintained on the ground of 

 their multicellular spores, and on account of the presence of peculiar 

 protonema-threads or of mucous cells on the leaves. The occurrence of 

 dwarf male plants in these genera has been demonstrated. Turning 

 now to the liverworts, we find detailed investigations of the following : 

 Gottschea ; hepatics with paraphyllia (e.g. Marsupidium sehdosum, 

 Ghandonanthus squarrosus, etc.) ; marsupiferous Jungermanniacese, in- 

 cluding the types represented by Tylimanthus and Isotachis, etc. ; 

 Radula uvifera with its heterophylly ; Hymenophytum and the differ- 

 entiation of its thallus ; Blyttia xiphioides ; Metzgeria saccata with its 

 curious water-sacs ; Treubia, which is not rare in New Zealand ; Moerlcia 

 Coehiynii, a new species ; Marchantia foliacea with its relatively xero- 

 philous structure ; Anthocerotege, especially A. giganteus (a transition to-
