330 SUMMARY OF CURRENT RESEARCHES RELATING TO 



the mountains between Halamdart and Marinte, in Irak-Adjem by 

 Belanger, and described by Bory as Notholcena persica. Since then it 

 has been found in Transcaucasia, Dalmatia, and Italy, and more recently 

 in the Himalayas, Asia Minor, Greece, and Algeria. C. Szovitsii is the 

 only species of the section Physapteris which occurs in the old world, 

 the other four species being confined to the Andes, the United States, 

 and Chili. The author then discusses the presence of the plant in the 

 two recorded Italian localities, Monte Mauro and Monte Baldo. The 

 latter must, in his opinion, be excluded from the area of this fern's 

 distribution ; and the reasons for this opinion are fully stated. On 

 Monte Mauro, near Faenza, it has been found by the author himself as 

 well as by two others previously, and the origin of this isolated habitat 

 is discussed, the author considering that the plant has emigrated to Italy 

 from Dalmatia, the spores being carried by the wind. 



Genus Stenochlsena.* — L. M. Underwood has made a careful study 

 of this genus. He divides it into four sections : Eustenochlcma, 

 Cafraria, Teratophyllum, and Lomariopsis. The species of the first 

 three sections are all confined to the tropics of the Old World. Those of 

 the section Lomariopsis are divided between the tropics of the Old and 

 New Worlds, approximately in the ratio of 3 to 2. Keys to the species 

 are given, and to each species is appended a list of synonymy with 

 references to literature, a list of published figures, and the geographical 

 distribution. Three new species are described, and several species 

 hitherto included in other genera, are now transferred to Stenochlama. 

 There are ten figures of pinnae, natural size. 



Lycopodium in the American Tropics.f — L. M. Underwood and 

 F. E. Lloyd publish an account of the species of this genus from the 

 West Indies, the Santa Marta region of Columbia, the Andean region of 

 Bolivia and Mexico ; occasional species from S. America are also included. 

 The list does not profess to be exhaustive, as many regions need still 

 further exploration. The authors treat the genus under the three 

 sections, Selago, Lepidotis, and Diphasium. Keys are given to the species 

 included in each section and subsection, and each species is then treated 

 separately, critical notes, range, and quotation of specimens in herbaria 

 being given. Seventeen new species are described. 



Chinese Ferns. — H. Christ % publishes an account of the ferns col- 

 lected in Western China (1903-4) by E. H. Wilson for Veitch & Sons. 

 The collection was made in the western part of Sze Tchuen, many 

 specimens coming from Mt. Omei, which was visited by Faber in 1887. 

 Of the 160 forms enumerated 21 species and 11 varieties are new, 74 

 are endemic, and 60 others are essentially Chinese but have spread 

 westwards along the southern slope of the Himalayas, and were first 

 recorded from that region. The author insists upon the great influence 

 exercised by huge mountain ranges upon the migration of plants by 

 means of the controlling agents — wind and rain. H. Leveille § records
