52 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Bryophyta. 

 (By A. Gepp.) 



New Families of Mosses.* — M. Fleischer publishes descriptions of 

 two new families of mosses — Pterobryacese and Trachypodacese ; three 

 new genera — Pterobryopsis, Mullerobryum, and Trachypodopsis ; and a 

 new species. Pterobryaceee contains three sub-families — (Edicladiese, 

 Pterobryeee, and Grarovagliese, and is allied to Leucodontacese. Trachy- 

 podaceas forms a rather isolated group, though formerly ranked under 

 Papillaria. Pterobryopsis consists of two groups — Eupterobryopsis, 

 containing five species, and Pterobryodendron, containing twenty-one 

 species, which mostly had been placed in Garovaglia. Mullerobryum 

 contains one species, which grows in Queensland. 



New Malayan Mosses.f — M. Fleischer publishes descriptions of the 

 novelties issued in the seventh series of his "Musci Archipelagi Indici 

 Exsiccati" (1904). These include two new genera — Aerobryopsis and 

 Macrothamnium, and several new species and varieties. Aerobryopsis 

 contains ten species, gleaned from Aerobryum, Eriocladium, Meteorium, 

 etc., and, apart from its vegetative differences, is characterised by its 

 very long papillose seta and sparsely hairy calyptra. Macrothamnium 

 consists of five species taken from Microthamnium, and characterised by 

 their large and well developed sporogonia. Floribundaria of C. Mueller 

 is confirmed as a valid genus on account of its Leskioid peristome, thus 

 differing from the Neckeroid peristome of Papillaria, of which genus it 

 once formed a section. 



Mosses of Formosa.f — J. Cardot publishes the first adequate 

 account of the mosses of the island of Formosa. Hitherto no more 

 than seven species were known ; the list is now raised to 130 species, 37 

 of which are new to science, but are not all likely to prove endemic to 

 the island. The specimens were collected by the Abbe Faurie in 1903 

 at a few places on the coast and on a low mountain. The rest of the 

 island and a high chain of mountains, well watered and timbered, have 

 yet to be explored, and will probably yield as many more species. The 

 character of the moss-flora is mixed ; 34 of the species are of Japanese 

 type, and 7 are Chinese, finding their southern limit in Formosa ; 21 

 are Malayan ; 18 occur in Ceylon, and 7 in Europe. Critical notes are 

 appended to most of the species. The new species are figured. 



Moss-Distribution in Baden.§ — T. Herzog, having completed the 

 systematic and descriptive part of his bryogeographic sketch of the 

 moss-flora of Baden, passes on to discuss the distribution of all the 527 

 species according to (1) zones of altitude, (2) nature of substratum. (1) 

 292 species inhabit the plains, 336 the hills, 360 the mountains, and 117 

 the sub-alpine region ; and numerous further statistics are added. (2) 

 As to substratum and environment, the author gives lists of species first
