mossy forest, 'and the presence above this of a montane brush which 

 degenerates in places to a mere heath composed of a few vascular plants 

 of Australian and north-temperate type. The author supplies some 

 remarks on the geographical distribution of the species in the collection ; 

 the fern-flora has migrated from the south, and the Celebes element 

 seems to dominate over the Bornean. He also points out what large 

 areas on the flanks of the mountains, where the fern vegetation reaches 

 its most luxuriant element, remain to be explored. In the systematic 

 list are 184 ferns and 18 fern-allies. Of the former 15 are new species, 

 and 1 of the latter. 



Chinese Ferns.* — H. Christ gives an account of the more interesting 

 ferns in a collection of 100 specimens received from F, Ducloux, a 

 missionary in Yunnan. Descriptions of ten new species and two new 

 varieties are supplied. He also describes twelve species and two varieties 

 in some collections made by Peres Esquirol and Cavalerie in the province 

 of Kouy-Tcheou. 



North American Ferns.f — A. K. Harrison and other members of a 

 special committee of the New England Botanical Club publish a listrof 

 o9 species, representing the fern-flora growing within 25 miles of Boston, 

 a fairly well marked geographical unit. The hst is a preliminary one, 

 but is founded on numerous data. 



R. C. Benedict | publishes notes on some ferns collected near Orange, 

 New Jersey, principally concerned with Bnjofteris s})imilosa and its 

 varieties, and the question whether the type-form really occurs in the 

 United States. In an old well was found a self-established specimen of 

 the Japanese Gyrtomium falcaiam. 



Cibotium Baranetz and its Sub-species.§ — H. Christ, having made a 

 study of the collective species Cibotium Baranetz (erroneously spelled 

 " Burometz " in consequence of a typographical error — see Kunze Suppl. 

 Schknhr, i., 63, in note), finds that the recognition of several sub-species 

 is well justified. He gives descriptions of the following : — G. Baranetz 

 J. Sm., G. assamicum Hook., G. sumatranimi (a new sub-species), G. 

 Cumingii Kunze. 



Gleicheniacese of North America. |1 — L. M. Underwood publishes 

 his eighth article on American ferns, namely, a preHminary review of 

 the North American Gleicheniaceffi. He recognises as valid genera 

 Platyzoma R. Br., Stromatopteris Mett., Gleichenia J. E. Sm., and Bicran- 

 0]}teris Bernh., and supplies a table of characters by which they may be 

 separated. The first two genera are monotypic and Australasian. The 

 author insists upon the importance of a close field-study of the larger 

 members of Bicranopterbs, especially in their respective type localities, 

 since the specimens are difficult to prepare for the herbarium, and some of 

 the type-material in existence is too meagre to afford an intelligible con- 

 ception of the species. It is of great importance to obtain the primary
