receptacnlum, which by their capillary attraction constitute an apparatus 

 for quickly diffusing the water in which the male reproductive cells are 

 transported. 



Tortula aciphylla in Britain.* — W. E. Nicholson records the first 

 rinding of Tortula aciphylla in Britain, namely, on Ben Lawers, last 

 June. It is a moss of the European mountains, and is found in North 

 America. Nicholson shows how it is distinguished from T. ruralis in 

 shape of capsule and colour of oophyte, but especially in the excurrent 

 hair-point of the leaves, which is reddish and nearly smooth as com- 

 pared with the spinose hyaline hair-point of T. ruralis. T. aciphylla is 

 an alpine, T. ruralis a lowland species. 



Ricciocarpus natans.f— W. West publishes a note on Ricciocarpus 

 nutans. It was growing among Scirpus lacustris, in a pond near Don- 

 caster, last Jane, and was associated with Lemna trisulca. In thin open 

 parts the latter predominated to the exclusion of the other, whereas in 

 well-shaded places the Ricciocarpus grew almost pure. 



Belgian Bryophytes. — A. CornetJ announces the discovery of Bryum 

 fallax Milde in Belgium. He found it growing plentifully on mortar, 

 sterile and associated with Trichostomum crispulum. He points out its 

 resemblance to, and difference from, B, pattens, and sketches its distri- 

 bution. 



He also records § Webera Rothii Correns and Lophozia baclensis 

 Schiffn. as additions to the Belgian flora. Webera Rothii is one of the 

 four species into which W. annotina has been split, and is as yet not 

 much known, but has been recorded for North Germany and Tyrol. 

 Lophozia badensis is a species intermediate between L. turbinata and L. 

 Mwlleri, and as it has been united with the former species by several 

 authors its proper distribution is not clear. 



H. van den Broek |j publishes a list of the Sphagnaceag of the neigh- 

 bourhood of Antwerp. He has collected during twenty-five years, during 

 which time the number of European species of Sphagnum has been 

 doubled. In preparing his list he has followed the system elaborated by 

 Warnstorf , and enumerates thirty-one species and numerous varieties and 

 forms. 



Mosses of Carinthia.^f — F. Kern gives an account of the moss-flora 

 of the Carinthian Alps, prefaced by a brief geological sketch of the 

 district, and some indication of the effect of the calcareous and slate rocks 

 respectively upon the flora. He enumerates 210 species of moss and 

 56 hepatics, citing their localities and altitudes. 



European Hepatics.** — K. Mueller, in the ninth part of his Die 

 Lebermoose, gives descriptions and figures of the remaining three species
