REPORTS. 



As will be seen by the list which follows, additions have 

 been made during the past twelve months to the records of 

 no less than four of the Sarnian Islands, viz., Guernsey, 

 Alderney, Sark and Jethou. Mr. Derrick has discovered 

 an unrecorded fern in Sark, and another in Jethou. 

 Several additional mosses and hepaticae have been found in 

 Guernsey, Alderney and Sark, by Mr. P. G. M. Rhodes, B.A., 

 of Cambridge University, and among them there is one 

 species (Brachythecium vehttinum) not previously detected in 

 the Channel Islands. Mr. Rhodes has also added four lichens 

 to the Guernsey list. 



My own share of the work is confined to Sark, where 

 during a week's visit in the spring I found a new flowering- 

 plant, four new mosses, and an unrecorded seaweed. Sark 

 is not at all an ideal collecting-ground for a seaweed collector ; 

 it is far inferior, from the nature of the coast, to Herm 

 or Alderney. But the scanty list at present on record might 

 be considerably enlarged with very little trouble. 



A paper was recently read before the Society on the 

 vegetation of some of the small islets on our coasts. Persons 

 who are interested in the subject of plant distribution will 

 find in it matter for some amount of attentive study and 

 comparison. 



Two rare Guernsey plants have been found in new 

 stations that deserve notice. In May last the Rev. R. H. 

 Tourtel sent me a fresh specimen of the Star of Bethlehem 

 (Ornithogalum umbellatum) which had been found by Miss 

 Tourtel growing in small quantity in a field quite on the 

 edge of the Thielles cliffs. During the summer I noticed 

 several small patches of the Heath Bedstraw {Galium 

 saxatile) in flower on the cliffs above Saints Bay. This 

 is one of our most local plants, hitherto only known to 

 occur in two or three places at the extreme northern end 

 of L'Ancresse Common.
