The WATSON 



Botanical Exchange Club. 



REPORT FOR 1900-1901. 



The number of plants contributed was 3,155 ; a number 

 considerably in excess of that in late years. Twenty-four 

 members sent in plants for distribution and naming, and the 

 material, as a whole, was satisfactory, many specimens being 

 very beautifully prepared. 



At p. 14, will be found a further and full description of 

 the new Bramble, Ruhiis Lettii, mentioned in last year's 

 Keport, and at p. 25, a new variety of Chenopodumi album is 

 reported. 



Another plant of great interest is the new generic hybrid 

 Bvomiis commutatus, Schrad. x Loliiim perenne L. [p. 35), the 

 lately discovered Alopecums hyhvidiis, Wimm., {p. 34), the new 

 Mullein hybrid [Vevhascum pulverulent um x Thapsus) (p 24), and 

 the new Scotch Betula [B. alpestris, Fr.) {p. 28). 



A feature of the present distribution is the large number 

 of Aliens sent in ; on many of these Mr. S. T. Dunn has 

 kindly written notes. 



As usual, the Club is much indebted to the Rev. W. Moyle 

 Kogers for examining and noting upon the Rubi. The thanks
