318 BOTANY, 



British fungi and a paper on a new genus, Peniophora, in Grevillea. The 

 articles by Von Tbuemeu are numerous and scattered in several jour- 

 nals, and include descriptions of species from Egypt, Siberia, Germany, 

 and other countries. 



The development ofAcidium abietimim has been very carefully studied 

 by De Bary, who connects it with stylosporic and final forms found on 

 alpine species of Rhododendron. A nearly related form is found in Fin- 

 land, on Ledum, according to Woronin. In a paper on the Development 

 of some Uredinece in the Beitriige zur Biologic, Schroeter gives an ac- 

 count of the development of a Uredo on Ledum, and a detailed account of 

 a number of different Fuccinke. Cornu has published a number of scat- 

 tered notes in the Bull. Soc. France, of which may be mentioned in this 

 connection some BemarJcs on Uredinece, especially the genus Eoestelia. 



HIGHER CRYPTOGtAMS AND MUSCINEJE. 



In this country the principal work published during the year has been 

 the continuation of Eaton's Ferns of North America. The same writer 

 also published in the Bull. Torr. Club a paper on New and little-hioicn 

 Ferns of the United States, the species mentioned being principally from 

 Florida. A second illustrated work is Fern Etchings, by John William- 

 sou, which contains illustrations of 08 ferns of the United States. Baker 

 has described, in the Loudon Journal of Botany, ferns from Borneo, the 

 Fiji Islands, and the Sulu Archipelago. 



In mosses we have a paper by Lesquereux and James in the Proc. 

 Am. Acad, of Arts and Sciences, entitled Descriptions of some neiv species 

 of North American Mosses, with a note by W. P. Schimper, and three 

 papers by C. F. Austin, onejon Some Neio Musci, in the Botanical Gazette, 

 and Bryological Notes and Notes on Hepaticologg, in the Bull. Torr. Club. 

 In the last article, besides si)ecies of the United States, a number of 

 species were described from the Sandwich Islands. Of foreign writings 

 on mosses and hepatics, we may mention papers by Lindbergon northern 

 liverworts and mosses, Massalongo's Hepaticologia Veneta in the pro- 

 ceedings of the Soc. Yeneto-Trentina, and Hampe's Enumeration of some 

 Brazilian Mosses. 



Of developmental papers and those concerned with minute anatomy 

 in this department of botany the Untersuchungen iiber Lehermoose, by 

 Leitgeb, deserve especial notice. Of the work just named, parts four 

 and five appeared in 1879, and treated of the Eiccew and Anthoceratece. 

 The same writer also published a paper on the development of ferns in 

 the proceedings of the Vienna Academy of Sciences. The sexual gen- 

 eration of the Marrattiew was described and fully illustrated by Jonk- 

 mann in a paraj^hlet published at Utrecht. Bauke, in a study of the 

 prothalli of Platycerium grande, came to the conclusion that the bilateral 

 form of the prothalli was not owing to any inherent property, but to the 

 action of gravity. In a short i)aper in Flora, Bauke also has some re-
