Primula Aretotis hybrida. By G. Arends {Die Gart. p. 577 ; 

 7/9/1901). — The author describes, in an interesting article, how he 

 acquired from England a Primula under name P. viscosa nivalis (identical 

 with P. Aretotis, Kern, var. alhiflora), but, being unable to seed it, crossed 

 it with the white P. puhescens ciliata, resulting in vigorous growing 

 white-fiowering forms similar to the English P. viscosa nivalis. By 

 again intercrossing with P. viscosa and other allied species, the raiser 

 obtained a fine lot of large-flowering forms with yellow, pink, purple, and 

 red flowers, resembling much the parent P. viscosa nivalis as far as 

 growth is concerned. — G. B. 



Primula capitata and Primula cashmeriana. By F. Rehnelt, 

 Garteninspector in Giessen (Die Gart.^^. 26 & 27, 19/10/1901).— Protest, 

 against the wrongful use of these names in Germany. P. capjitata, 

 summer flowering, with blue heads of flowers, is less known, as in England, 

 while P. cashmeriana, spring flowering, with lilac-purple Howers, usually 

 goes under the name of P. capitata. Full description and illustration of 

 leaves &c. — G. B.

 mentioned in several English journals. — G. B. 



Primula, New Alpine {Gard. Mag. 2,485, p. 371, 15/6/1901).— 

 Under the name of Primula viscosa, ' Mrs. J. H. Wilson,' a new variety 

 is described and illustrated. It has larger flowers than those of the type, 

 and they are of a rich violet-blue colour. It originated as a seedling in 

 Mr. Wilson's garden at Handsworth, Sheffield. — W. G.
