198 SUMMARY OF CUERKNT RESEARCHES RELATING TO 



new species, CryptoU^Jtodon acuminatus, is formed, for Leptodon 

 Fliwini CM. YSiV.folns acmninatis CM. Miiller's Leptodon species in 

 his herbarium belong to four different genera, according to Fleischer. 

 He gives similar treatment to the genera Dusenia, Cladomnium, Le^jyro- 

 don, Leucodon, Erythrodontium and Pt&rigynandnmi. The drastic 

 treatment of the author threatens to leave very little of C. Miiller's 

 nomenclature intact. E. S. G. 



Mosses of Papuasia. — Max Fleischer {Enqler''s Bot. Jahrh., 1917, 

 55, rJ-:37, 1 pi. ; see also Bot Centralbl., 1918, 138, 152-3). An 

 account of several noteworthy mosses from the islands of the New 

 Guinea group, including two new species. The principal interest of the 

 paper lies in the geographical notes, which fill in many gaps in our 

 knowledge of the distribution and mode of life of the Sphagnacea?, 

 Fissidentaceffi, Dicranacese, Leucophanacea?, Syrrhopodontacete, Splach- 

 nacea?, Rhizogoniaceffi, Hypnodendracege and Othotrichace^e. The 

 information is derived from personal observations of Papuan plants by 

 the author himself. A. G. 



Remarks on the Contributions of J. G-ybrffy to the Histolog'y of 

 Ephemeropsis tjibodensis in Ann. Jard. Bot. Buitenzorg and else- 

 where. — Max Fleischer {Hedwigia, 1917, 59, 209-11 ; see also Bot. 

 Centralbl., 1918, 138, 152). By means of very detailed anatomical 

 studies of the sporophyte of Epimneroiisis tjibodensis, Gyorffy has ex- 

 tended the description of the species beyond the limits laid down by 

 Max Fleischer in his " Mosses of Buitenzorg." In certain points he 

 considered his view a correction and improvement on that of Fleischer. 

 In the present paper Fleischer answers Gyorffy, and maintains his own 

 point of view. E. S. G. 



Third Contribution to the Moss Flora of the Erzgebirge. — J. 

 Roll {Hedivigia, 1917, 59, 285-300 ; see also Bot. Centralbl., 1918, 

 138, 153). A bryofloristic treatment of the central portion of the 

 Erzgebirge, principally of the places Reitzenhain and Sebastiansberg, on 

 the ridge of the mountains. Both are surrounded by great moorlands, 

 about 740 to 880 metres above sea level. The special features of the 

 district are described, followed by a synopsis of the mosses observed. 

 Among these are Dicranella squarrosa, Bryiim Davalii, and Dreiiano- 

 cladus hercynicus. Sphagnacete are the most abundant, and their 

 treatment occupies the larger part of the paper. Thirty-four species are 

 recorded as well as numerous forms. E. S. G. 



New Hepatic for the Iberian Peninsula. — F. Beltran {Bol. R. 

 Soc. Espah. Hist. Nat., 1920, 20, 310-12). The species in question is 

 Ricciocarpus natans Corda, f . natans, which was found in the village of 

 El Saier, near Albufera in Valencia. It was growing in a short and 

 narrow canal intermixed with Lemna, which it closely resembles. Its 

 discovery was made by chance during a search among the Lemna for 

 larvte. The material was taken to the botanical laboratory of the 

 University of Barcelona, where it was successfully cultivated in spite of 

 the ravages of a larva. Antheridia were found on mature plants, but
