690 SUMMARY OF CURRENT EESEAECHFS RELATING TO 



Muscinese of Christmas Island.* — H. N. Ridley, in the account of 

 his expedition to Christmas Island, gives a list of fifteen mosses and an 

 hepatic, determined by A. Gepp. Two of the mosses are new to science. 



South American Mosses.| — V. F. Brotherus publishes another list 

 of mosses collected by E. Ule. The total of these is 113 species, and 

 they were gathered on the Amazon and Lower Andes. Among them 

 are forty-four new species. Uleobryum peruvianum represents a new 

 genus of Pottiacese. It is apparently most nearly related to K. Midler's 

 Phasconica, and somewhat resembles Mierobryum in habit. 



North American Muscineae. — C. C. Haynes $ points out the resem- 

 blances and differences between Cephalozia fluitans and Lophozia inflata, 

 and cites Schiffner's discovery that the deciduous perianths of the latter 

 function as organs of vegetative reproduction. Figures are given. 

 A. W. Evans § describes Lepidozia sylvatka, a new species of hepatic 

 split off from L. setacea. It occurs in several of the eastern States. 

 G. N. Best || describes and figures Ptychomitrium Leiberyii, a new species 



of moss gathered in Arizona.

Yorkshire Mosses. 1[ — W. Ingham records stations for some new and 

 rare Yorkshire Muscineag — Physcomitrella patens, Weisia mucronata, 

 Bryum murale, and Junyermannia Goulardi. This latter was previously 

 unknown in the British Isles, and, in Macvicar's opinion, would be better 

 regarded as a variety of J. sphcerocarpa. 



Luminosity of Schistostega.** — T. Gibbs describes the vivid 

 luminosity displayed by the protonema of this moss when suitably 

 illuminated, comparable to the metallic green seen on the breast of 

 some humming-birds. The plant occurs in crevices and rabbit-burrows 

 at several places in Derbyshire, but always on the Millstone Grit. 



New Scotch Mosses.ft — J. Stirton describes the following new 

 species and varieties of Scotch mosses : — Cynodontiwn aspereUum, 

 Campylopus prasinorvfus, C. rubiyinosus, G. purpurascens var. Kin- 

 layanus, Barbula viridescens, Leptotrichum confertum, Hypnum anoma- 

 lum, Plagiothecium trichodeum, and Ceratodon conicus var. acicul art's. 

 Also Campylopus Dickieamis from Lake Nyami in Central Africa. He 

 finds Didymodon Jenneri Schimp. (1868) to be synonymous with 

 Cynodontium laxirete Dixon, with C. polycarpoides Stirt, and 0. poly- 

 carpum var. Ittviyatum Hagen, and re-christens it C. Jenneri. Under 

 Dicranidia fuscorufa, he gives details of what is apparently a new moss 

 previously mistaken for Dicranella curvata. He sinks Barbula assimu- 

 lans Stirt. into a variety of B. insulana, and re-describes Leptotrichum 

 compactum Stirt. 



French Hepaticse.JJ — I. Douin publishes an annotated list of seventy- 

 three species of Hepaticse, thereby extending the known distribution of
