short cilia-like teeth. It is most closely allied to G. Jaclcii, and o•l■o^Ys 

 in thick tufts of Dicranum scoparium. New forms are described, and 

 ■.twelve species are recorded as new to Dalmatia. 



New Mosses from East Asia and South America.*— T. Herzog 

 publishes new genera and species of mosses from Ceram and Buru, from 

 Malacca and New Guinea, from the low-lying country of La Plata and 

 Eastern Bolivia, and from the High Cordilleras in the province of 

 Mendoza. The mosses were collected by various people. The new 

 genus Hymenodontopsis resembles Hymmodon in habit and peristome, 

 but differs in having smooth cells, globular capsules, and a remarkably 

 long beak to the calyptra. PseudothvMkm differs from TJmkUiim 

 •chiefly in its lack of paraphyllia and the shape of the cells, which are 

 elliptic to lanceolate-elliptic. Cribrodontium is allied to Entodon, but 

 differs in the sieve-like perforations in the thickened lamina of the 

 teeth, and also in the apical splitting of the teeth. 



Bryophyta of Bolivia.t — T. Herzog publishes a full account of his 

 second journey to Bolivia in the autumn of 1910. His object was to 

 explore thoroughly the Eastern Cordilleras between Santa Cruz and the 

 high plateau of Titikaka, a region hitherto but poorly known botanically. 

 It includes tropical primevarforest and pampas, and rises to the region 

 of the eternal snow, so that the material collected was plentiful and 

 varied. The species of mosses number 706, the liverworts 444— a 

 total of 1150 Bryophytes in all. After a geographical introduction 

 describing the tour follows the systematic portion. The five Sphagna 

 are determined by J. KoU, the Andreaiales by V. F. Brotherus. New 

 species are described. The Eubryales are worked out almost entirely 

 by the author himself. He describes eight new genera and many new 

 species. As an instance of the necessity of enlarging our views on 

 morphology and phylogeny, an example niay be quoted of a new species, 

 Catharinsea elameUosa, which was found in fruit ; the lamellae on the 

 upper leaf surface, which were considered obligatory for the genus, are 

 entirely wanting. Multicellular spores are recorded for two new species, 

 Cryphsea gracilUma and C. nmcrospora. Bartramla and Breutelia are 

 richly represented in the region. The new species are well figured, both 

 in the text and on plates. 



The Hepaticfe are worked out by F. Stephani, who describes as new 

 53 p.c. of the species. In the genus Playiochila 87 of the 137 species 

 recorded are regarded as new. Numerous figures drawn in outline 

 show the differences in structure of the newly described species. 



In the geographical part of the work the author gives a review of 

 the most important families of the Andine moss-flora of Bolivia, of 

 which Prion odontaceffi is the chief. He also describes the whole 

 explored region with its different sections and the species inhabiting 

 them. Under " moss-formations " he treats of the biology and physiog-
