striatulus Schiffn., Cephaloziella Limjmchtii Warnst. The Lophozia 

 bade/isis had been confused with L. turhiimta. Some other interesting 

 records are : Anthella julacea, HygrohieJla laxifolia, Gymnomitrium 

 adustum, Pallavicinia Flotowiana, Lophozia atlantica, Sphenolobus 

 Pearsoni, Anastrepta orcadensis. 



Hepaticse of Porto Rico.* — A. W. Evans, continuing his study of 

 the Hepaticae of Porto Rico, treats of the four genera Stictolejeunea, 

 Nenrolejeunea, Omphalanthus, and Lopholejeunea. The type of Sticto- 

 lejeunea, S. squamata, is widely distributed in the American tropics. It 

 was originally recorded as found on myrtle bark from the East Indies 

 and subsequently as from Hawaii. These records, however, have never 

 been confirmed, and must be regarded as false. The genus is remarkable 

 for its Frullanioid branching and for the ocelli with which its leaves are 

 spotted. In Neurolejeunea two of the three species have a false nerve 

 (a row of ocelli) in their leaves. A fourth species, which links up this 

 genus with Ceratolejeunea, is here transferred to the latter genus, to 

 which its affinity is the stronger. The two genera are separated by 

 characters derived from the leaf -cells, lobules, and perianths. In Neuro- 

 lejeunea catenulata and Ceratolejeunea portoricensis the apices of the 

 leaves are sometimes curiously scarious or lacinulate with hyaline cells, 

 which apparently aid the plant in clinging to the substratum. The 

 genus Omphalanthus is represented by a single species widely distributed 

 in tropical America, and of doubtful occurrence elsewhere. Lopholejeunea 

 is a larger genus, characterised by its sharply keeled and laciniate peri- 

 anth, and is represented by more than thirty species mostly found in 

 the tropics. Six of these occur in America, and three of these are found 

 sparingly in Porto Rico, one being new to science. All the plants in 

 this paper are redescribed in full detail and freely illustrated. 



Hepatics of Tuscany.f — E. Barsali has compiled a list of 37 species 

 of hepatics with their distribution in Tuscany. It is as far as possible 

 exhaustive, and is preceded by a general introduction in which the geo- 

 graphical distribution of these plants is discussed. Some species prefer 

 a calcareous soil, others a silicious soil ; others again abound on the 

 trunks of trees in damp neighbourhoods ; others are found in stagnant 

 or running water. In the Tuscan plains the species are few, chiefly 

 thalloid forms. In the olive groves of the lower hills, especially near 

 water, more species are found. But it is in the region of chestnut and 

 oak forests that most of the species occur, on the ground, on rocks, on 

 living or dead trunks, or indifferent as to their substratum. From alti- 

 tudes of over 5000 feet some twenty-two Alpine species are recorded. 



New Madotheca from China. | — C. Massalongo gives a diagnosis of 

 Madotheca nitidula, a new Chinese hepatic collected in Shen-si by 

 Giraldi. It was too late for inclusion in E. Levier's paper on Giraldi's 

 Shen-si Bryophytes published recently in the Nuovo Giorn. Bot. Ital.
