SUMMARY OF CURRENT RESEARCHES RELATING TO 



W. X. Clute* has collected under the title Pteridographia a variety 

 of Dotes on New York ferns, Classification-systems for Nephrodium, The 

 Virtues of Polypody, Bybrid ferns, NephroXepu Dreyerii, N. Marshalli. 



S. F. Blakef publishes notes on some Pteridophytes from eastern 

 .Massachusetts. Winter occurrences of Woodsia obtusa were noted in 

 March 1909 ; they are rare in the region. Many winter specimens of 

 Dicksonia punctilobula were also found in sheltered situations. The 

 fresh green appearance of small fronds suggested that growth had 

 occurred on favourable days during winter. It is probable that Botry- 

 chium obliquum var. oneidmse is fairly well distributed in eastern 

 Massachusetts, but is often mistaken for B. ternatum var. intermedin m, 

 with which it seems to intergrade. Lycopodium clavatum var. mega- 

 stachyon, a recently described variety, occurs in east as well as in west 

 Massachusetts and in New Hampshire. 



W. H. Blanchard J gives a description of Lycopodium ffabelliforme, a 

 new species raised from varietal rank ; and he adduces a number of 

 reasons as to why it is a good species. It can no longer be regarded as 

 a variety of L. complanatum, being more distinct from that species than 

 is L. tristachyum. It differs in habit, method of growth, and other 

 characters. The specimens described came from Caribou, Maine. 



Ferns of the Falkland Islands. § — 0. H. Wright, in giving an 

 account of the flora of the Falkland Islands, includes a list of thirteen 

 ferns gathered by Yallentin and others. 



Chinese Ferns. || — C. G. Matthew gives an alphabetical enumeration 

 of Chinese ferns, containing nearly 1100 entries with citations, distribu- 

 tion, and, where necessary, some synonyms. The system of nomenclature 

 is that of Dieis and of Christensen. 



E. Panipanini,^" in a supplementary enumeration of the vascular 

 plants collected by the Rev. P. C. Silvestre in Hu-peh during the years 

 1904-7, gives a list of forty-two Pteridophytes, with their localities, 

 altitudes, etc. 



Ferns of Corea and Quelpaert.** — C. Christensen gives a list of 

 thirty-eight ferns collected in Quelpaert Island by P. Taquet in 1910, 

 and adds a few descriptions and critical notes. In a supplement eight 

 ferns new to Corea are recorded. 



„ ^ Ferns of Annam.ft — H. Christ describes Drymoglossum cordatum, a 

 new fern collected in Annam by Cadiere, and preserved in the Paris 

 Museum.
