 "The Pollination of the Primrose." Mr. James Groves gives an 

 account of Ceylon Charophyta, obtained by Mr. T. B. Blow, who has 

 collected them largely in all parts of the world ; twelve species are 

 enumerated, two of which {NiteJla mucosa and N. leptodactyla — 

 the latter admirably figured by Miss Groves)— are new. Sir William

The Journal of the Royal Horticultural Society (xlvii. parts 2 

 and 3 ; September) is somewhat lacking in papers of s])ecial botanical 

 interest, Mr. E. J. Holland, President of the Pose Society, has 

 an interesting paper on Scented Roses ; Dr. "W. Bewley writes on 

 Tomato Diseases ; and Mr. H. E. Luxmoore has a charming account 

 of a rare Latin poem — title not specified — on Gardening, by Walafred 

 Strabo, a monk of Weissenburg, written about 800 a.d., which 

 deserves a place in one of our literary magazines, although its subject 

 entitles it to its present position. 



CoKiiECTiONS. By an unfortunate misprint, Mr. H. W. Pugsley's 

 name is misprinted " Kigsley " at the end of the note on Ophiu- 

 f/lossum on p. 301. Mr. C. H. Wright points out to us that the 

 statement (p. 274) that Winchester is not on the G.W.P. is in- 

 correct : a line from Didcot to Winchester through Newbury was 

 constructed about thirty years ago. The Messrs. Stephenson send 

 a similar correction and mention that they have seen Scnecio squalidus 

 in great plenty on mine-tips near Wrexham.
