406 BOTANY. 



pricht in relation to the determination of certain species in the Bot. 

 Centralblatt, to which in return Warustorf replied at some length. 

 Limpricht has described some mosses new to Silesia and new species of 

 the genus Sarcoscyphus. I>ie Moose DeuUchlands is the title of a work by 

 P. Sydow, intended as an introduction to the study and determination 

 of German mosses. Mosses from the north of Europe have been de- 

 scribed by Lindberg, from the Pyrenees by Eenauld, from Brazil by 

 Hampe, and from Eeunion and Madagascar by Mueller and Geheeb in 

 Reliquice Butenhergiance. Four new genera from India, Africa, and Java 

 have been described by Mueller in the Bot. Centralblatt. 



Higher Cryptogams and Ferns. — In the second part of his Beitrage zur 

 vergleiclienden Entwic'kelungsgescliiclite dcr Sporangien, published in the 

 Botanische Zeitung of this year, Goebel shows that an archespor exists 

 in several vascular cryptogams where its existence had not been sus- 

 pected. After sc/m e obseivaticns onthe Marattiacea, OjMoglossum, 

 and Selaginella, he compares the development of the pollen-sacks of Coni- 

 ferce with their sporangia. In conclusion he proposes a new classifica- 

 tion of the higher cryptogams, including fossil as well as living repre- 

 sentatives. Prantl in the Botanische Zeitung gives the results of his 

 experiments on the nutrition of the fern prothalli and the distribution 

 of the sexual organs. The same writer has a preliminary communication 

 on the Morphology, Anatomy, and classification of Schizeocece in Engler's 

 Jahrb. In Eichler's Jahrb. is a review of the genus Adiantum by Max 

 Xuhn. Additions to the fern flora of the West Indies have been made 

 by Jenman. A number of pai)ers on American ferns have appeared in 

 the Torrey Bulletin and Botanical Gazette. In the first-named journal 

 are Nos. 9, 10, and 11 orf Eaton's ^ew or LittleJcnoirn Ferns of the United 

 States, Qontskimng critical notes on species principally from the West, aiul 

 fi'om Florida. A new American fern, Cheilanthes Farishii, is described 

 and figured by G. E. Davenport, who also has a paper on Vernation in 

 Fotrychia, and one on Onoclea sensibilis var. ohtusilohata. There is also 

 a note by L. M. Underwood on the last-named species. Mr. John Eob- 

 inson records the occurrence of Botrychium simplex near Salem, Mass. 

 In the Botanical Gazette are accounts of New Mexican ferns by H. H. 

 Rusby, of Arkansas ferns by F. L. Harvey, and of Florida ferns by 

 Miss M. C. Reynolds. Sets of Trinidad ferns, collected by Fendler and 

 determined by Eaton, have been oifered for sale; also, the second series 

 of A. H. Curtiss's Southern Ferns. 



The development of Asolla has been made out for the first time by 

 Berggren, who published the results of liis investigations, with illustra- 

 tions, in the Proceedings of the University of Lund. The species studied 

 by him was Azolla CaroHiiiana, and the development, which was nearly 

 completely ascertained, although the act of fertilization was not directly 

 seen, was found to resemble closely that of Salvinia. A biological pecu- 

 liarity of Azolla Caroliniana was described by Westerniaier and Am- 

 bronn, who found that the root-cap remains but a short time, is then
