318 BOTANY. 



British fungi and a paper on a new geuus, Peniophora, in Gre^illea. The 

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

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

 and other countries. 



The develoj)ment of Acidiu7n ahietinum 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 Uredinefc in the Beitriige zur Biologie, Schroeter gives an ac- 

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

 a number of different Pu<iciniai. Cornu has published a number of scat- 

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

 connection some Bemarhs on Uredinecc, especially the genus BoesteUa. 



HIGHER CRYPTOGAMS AND MUSCINEiE. 



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-hwivn 

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

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

 son, which contains illustrations of C8 ferns of the United States. Baker 

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

 Fiji Islands, and the Sulu Archii)elago. 



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

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

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

 papers by C. F. Austin, one on Some Neio Musci, in the Botauiciil Gazette, 

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

 In the last article, besides species of the United States, a number of 

 species were described from the Sandwich Islands. Of foreign writiugs 

 on mosses and hepatics, we may mention papers by Lindberg on 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 iiher Lehermoose, by 

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

 and five appeared in 1879, and treated of the Biccece 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 Marrattiece was describetl and fully illustrated by Jonk- 

 manu in a pamjihlet published at Utrecht. Bauke, in a study of the 

 IJrothalli 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 paper in Flora, Bauke also has some re-
