of the spores of certain species of Orthotrichum which grow on trees is 

 dealt with ; and it is found that they require bark or woody humus for 

 their germination. 



Geographical Distribution of Mosses.* — J. Palacky continues his 

 studies on the distribution of the mosses. He divides the Acrocarpous 

 mosses into 23 families, and discusses the geographical distribution of 

 the genera of each in turn. 



Peristome of Mosses.f — H. Philibert concludes the tenth article 

 of his studies on the peristome of mosses by discussing the remarkable 

 structures that occur in Daicsonia and Buxbaumia. 



Abnormalities. — W. Monkemeyer $ describes and figures the leaf- 

 buds on a species of Harpidium gathered in a pool on the crest of the 

 Piiesengcbirge. The buds were swollen into galls and infested by 

 colonies of Anguillula. The leaves were much broadened and hollowed 

 out, and the character of their areolation was entirely altered. 



F. Tobler § gives figures and a description of a singular instance of a 

 plant of Polytrichum gracile Menz. bearing two setas capped by one 

 Galyptra, the longer one laxly coiled three times round the shorter. 

 Each arose from a separate vaginula ; the calyptra was the product of 

 the coalescence of two archegonia. 



Lists and New Species. — S. M. Macvicar || records and discusses 

 five hepatics found in Scotland and new to the British Isles. 



Th. Herzog % calls attention to the rich and interesting moss-flora of 

 the St. Wilhelm and Oberried valleys of the Black Forest of Baden, 

 where amongst other rarities is found Hi/jmum micans. He discusses 

 the distribution and affinities of this puzzling moss. 



F. Matouschek ** gives a list of the hepatics and mosses hitherto 

 discovered in Moravia and Eastern Silesia, together with the localities 

 in which they occur. In an introductory note he records the work of 

 previous collectors in the two districts. 



Dr. E. Jadcrholm ff gives a list of 31 mosses gathered in the Trans- 

 caucasian districts of Lenkoran and Baku by J. Mikutowicz. Six of 

 these are new to the region ; and no previous moss-flora of Baku appears 

 to have been published. 



Monkemeyer J J describes and figures Pleuridium nitidum Babenh. var. 

 anomalum var. nov., a curious and luxuriant variety found growing with 

 the type near Mittweida. 



F. Camus §§ publishes a preliminary note npon the Muscineae gathered 

 by him in Corsica during a month's tour in May and June 1901. Owing 

 to the snow-bound state of the Alpine region and the dried-up condition 

 of the coastal region, he was unable to form a just estimate of their 

 flora ; but he intends to return to the island in the full summer, and in 

 the winter to examine them under the best conditions. His attention
