"Rejuvenated" Stems in Aged Willows, The Production of. 



By Dr. G. Tischler {Flora, vol. xc. 1902, p. 278 ; 4 woodcuts).- 

 YVhen the heartwood of a Pollard Willow rots the splintwood survives ; 

 but this, too, may die in strips owing to damage to the bark &c. The 

 cambium of a strip of living splint-wood forms a callus, and extends its 

 crescent wings year by year till a circular stem, distinct from the old 

 trunk, is evolved from the original strip, connecting the head and the 

 roots. The figures are very interesting, and might well be reproduced 

 here. — M. H. 



Ribes, Some New Species of Pacific Coast. By Alice Eastwood 

 (Proc. Cal. Acad. Sci. 3rd series, Bot. vol. it, No. 7, pp. 241-254 ; 

 2 plates, 10 figures). — An interesting contribution to the literature of a 

 difficult genus. Nine species hitherto unnamed are described and illus- 

 trated. A key to all the Pacific Coast species, fifty-seven in number, 

 closes the paper.— C. H. S. 



Rose Fungus. Phragmidmm subcorticatum. By William Car- 

 ruthers (Jour. B.A.S. vol. lxii. p. 248 ; 1901). — " The diseased twigs of a 

 Hose tree from Cambridgeshire were found to be distorted from the 

 presence of the recidium form of the rust Phragmidium subcorticatum. 

 The different stages of the rust all develop on the same host, and the 

 fungus can be destroyed by spraying the plants with a solution of copper 

 sulphate. The diseased twigs and leaves should be gathered and burned."

Roses, Pruning". By J. H. Pemberton (Gard. Mag. No. 2524, 

 15/3/1902). — This matter at first sight may appear to be commonplace, 

 but when it is dealt with by a master in the art of Rose culture the 

 subject commands close attention. Mr. Pemberton classifies the garden 

 Roses and describes how they should be pruned, and specialises various 

 sorts that require different treatment in this direction from the rest. 

 Abstaining from pruning altogether is recommended in some sorts, such 

 as * La France,' and this may appear to be unusual practice until one 

 reads the results obtained. The proper pruning of Roses, as in other 

 flowering shrubs, is still an art about which we have yet a good deal to 

 learn, though a matter often considered of small importance by even 

 practical gardeners. The subject is continued in the following number
