 of the Santa Cruz peninsula, California. (Proceedings of the 

 Washington Academ}^ of Sciences. VII. p. 325—396. March 29. 1906.) 



The following new lichens are described: Usnea californica 

 Herre, Pnnnelia Herrei Zahlbruckner, Physcia pulverulenta isidiigera 

 Zahlbruckner and Gyrophora diaholica Zahlbruckner. 



The new name Cetraria [Centraria , in error] Tiickermani Herre 

 is proposed to replace C. glauca stenophylla Tuck., 1882, a preoc- 

 cupied name. 



Several combinations appearing without a second author-name 

 are possibly published here for the first time, though not so indi-

Dixon, H. N., A new species of Splachnobryutn , with notes on 

 the peristome. (Journal of Botan3^ XIV. London, March, 1907. 

 p. 81-85. plate 484. A.) 



The author gives a description of Splachnobryum delicattdunt , 

 a new species of moss found by G. Webster on brickwork in 

 hot-houses at Baldersby and Harrowgate, Yorkshire. This 

 species was probably imported with Cattleyas from tropica! 

 America, and is akin to 5. Wrightii and 5. Baileyi, but is distin- 

 guished from all members of the genus hy having a preperistome , 

 a series of projecting hyaline cells which subtend the peristome- 

 teeth, one to each tooth, on its outer side and near its base. The 

 author gives a detailed comparison of this peculiarity with the 

 typical structure described for 5. Boivini hy Philibert. The pre- 

 peristome of 5. delicatidiini is nearl)^ homologous with what is found 

 in some species of Orthotrichiim. Other species of Splachnobrymu 

 which have been introduced into Europe with stove-plants are: 

 5". Wrightii CM. at Glasnevin Dublin in 1872, and 5. Corbieri 

 Ren. et Card, at Cherbourg in 1902. A. Gepp.

The author adds 125 records to his Scottish Census. The species 

 added to the Scottish flora are five: Riccia crystallina L,, Lophosia 

 badensis Schiffn., Prionolobiis massalongi Schitfn., P. striatidus 

 Schiffn., Cephalosiella Liniprichtii Warnst. The Lophosia has been 

 confused previously with L. turbi)iata. A. Gepp.
