570 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Hepaticse of Dalmatia.* — V. Schiffner publishes a complete list of 

 all the species of Hepaticse hitherto known from Dalmatia. The total 

 number of species is thirty-eight, among which are two species new to 

 science, Riccia Levieri and Gephalozia Baumgartmri, which are both 

 described at some length. The former is most closely allied to Riccia 

 macrocarpa, from which it is distinguished by the presence of marginal 

 cilia, by a difference in the spores, etc. Gephalozia Baumgartmri is a 

 calcareous species, and most nearly allied to G. Bryhnii Schiffner, but is 

 a coarser plant, and differs in many details as well as in the manner of 

 growth and in habit. In appearance G. Baumgartneri resembles 

 C. stelhdifera, but differs also from that species in several points. The 

 small number of species recorded from Dalmatia is partly the result of 

 the small area of woodland and damp ground in that country, and partly 

 arises from the absence of collectors. The author records eighteen 

 species new to Dalmatia. 



Bohemian Mosses.f — F. Matouschek publishes the first part of his 

 revision of the moss herbarium in the Landes Museum at Prague. All 

 the plants, even the oldest, are recorded. The synonymy in this paper 

 is of great value, for the collection includes authentic species and varie- 

 ties of P. M. Opiz. Many critical species are here re-described, and of 

 others the distribution in Bohemia is given more accurately. Many 

 species must be removed from the list of Bohemian plants. A new 

 variety, Rhacomitrium heterostichum Hedw. var. epilosum Mat. is 

 described. Hepaticas are added at the end of the paper. The second 

 part of the work will appear in 11)07. 



Hungarian Mosses.J — I. Gyorffy, continuing his moss-flora of the 

 Hohe Tatra, publishes some additions to our knowledge of Plagiobryum 

 Zierii and P. demissum. He shows how the water-conducting tissue is 

 not confined to the costa, but includes other parts of the leaf ; the 

 deuter-cells in the costa are sometimes three instead of two ; the 

 chloroplasts in the leaf -cells are few, the leaves and stems being too 

 crowded to permit of free assimilation ; on the other hand, the neck of 

 the capsule is long, well provided with stomata, and eminently fitted for 

 its assimilative work ; the stomata are sunk in depressions, though 

 hitherto described as on a level with the neighbouring cells, which is 

 commonly the case among mosses. The distribution of the species is 

 rare in Hungary,. except in the Hohe Tatra. As to the other species, 

 P. demisswn, the leaves are ovate-lanceolate and long-pointed ; the- 

 curvature of the thick yellow seta and asymmetric capsule bend the tiny 

 operculum down till it is hidden in the tuft, and the neck of the capsule 

 is uppermost and exposed to the light, and acts as an assimilative organ. 

 The stomata lie on a level with the surrounding cells, and are abundant 

 on the neck. The spores persist in tetrads. The author has found the 

 species in Hungary, but only in the Hohe Tatra, and says it is probably 

 overlooked because of its small size.
