of the Qovelties are added — a new -Tims Sorolepidium (allied bo Poly- 



stichum), eleven species and a variety. And a report by Prof. Senn on 



the starch prepared from the rhizome of Pteridium at Echang on the 

 Yang-tze is included.

Variable Leaf-border in Fissidens.* — J. Roll writes on the leaf- 

 border of Fissidens Arnoldi Ruthe, which he states to be a variable 

 character. On the same stem he finds leaves with and without a border, 

 though as previously known the species was without any bordered leaves. 

 The plant may be included in Semilimbidium just as readily as in Aloma. 

 He discusses several other species which show a similar variability of 

 leaf-border. This has led to an unnecessary multiplication of species. 

 Limpricht regarded the leaf-border as so unstable a character that he 

 forebore to describe it at all in the case of some of the European specie-. 



Hepaticse Infected by Fungi.f — A. J. M. Garjeanne gives an 

 account of some fungi which infest the rhizoids of hepatica?, and which 

 in his opinion are not necessary to the life of the hepatics, and which 

 do neither harm nor good to the host-plants. If there is a symbiosis, it 

 is of a very ill-developed nature, unless in the case of Galypogeia trkho- 

 manis and Jnngermannia barbata. He gives a list of thirty-two hepaticae 

 which he examined, indicating opposite each species the extent to which 

 it was observed to be invaded by fungi. All the species mentioned are 

 as often found free from fungi, as invaded by them. In Galypogeia 

 trkhomanis and Lophozia inflata the fungi are provided with haustoria 

 which penetrate into the green cells. Various fungi take part in this 

 infection ; and among them is the new species, Mucor rhizophilus, 

 described by the author. 



Inflorescence of Funaria.J— J. M. Speer publishes some notes on 

 Funaria hygrometrica, in which it is shown that not only is the species 

 not "strictly dioecious," but when large quantities of it were examined, 

 cases were repeatedly found where two to three antheridia occurred 

 mixed with as many mature archegonia in the same inflorescence, ren- 

 dered conspicuous by its size. Usually eight to twelve neck canal cells 

 are found in the archegonium ; an instance with twenty-two such cells is 

 figured. Archegonia with two eggs and their proper rows of neck canal 

 cells are figured. 



Lesquereuxia.§ — L. Loeske publishes critical remarks on Lesquerevrin 

 and other allied genera. He sums up his views as follows : 1. Lindberg's 

 Lesquereuxia, which can be maintained as a composite genus, includes 

 nearly allied forms which may be grouped round Lescursea saxicoJa, 

 Pseudoleslcea atrovirens, and Ptychddium plicatum. 2. The forms cannot 

 however be separated into genera on the ground of single characters,
