H. oricntalis type, known as Lent Roses, are noted, and the best mode of 

 cultivating them, which was especially studied by Mr. Peter Barr in his 

 Tooting nursery, is described. Their botanical names are difficult to 

 assign and not trustworthy, as a large proportion of the best varieties are 

 hybrids.— C. W. D.

Hop and its English Varieties, The. By John Percival (Journ. 

 R.A.S. vol. lxii. pp. 67-95 ; figs. 1-22 ; 1901).— The author deals with the 

 structure and varieties of the Hop, and gives a number of excellent 

 photographic illustrations. The only two distinct species of Hops known 

 are the Japanese Hop (Humulus japonicus, Sieb. et Zucc), a native of 

 China and Japan ; the other, our ordinary Hop (Hamulus lupulus, L.), is a 

 native wild plant distributed all over Europe. The former is of no value 

 for brewing purposes, but is grown as an ornamental climber in gardens. 

 The seedlings of few plants vary so much as those of the Hop, and this 

 in spite of the fact that it is a species which has not been subject to 

 hybridisation. The varieties discussed are : ' Hobbs's Early ' (density =6); 

 'Prolific' (density about 6); ' Meopham ' (density=5) ; 1 Henham's 

 Jones' (density=7) ; ' Brambling ' (density=7) ; 'White's Early' 

 (density=7) ; ' Amos's Early Bird' (density about 8) ; ' Bennett's Early 

 Seedling ' (density=6) ; 1 Rodmersham or Mercer's Hop ' (density =7^-8); 

 ' Cobb's Hop ' (density =7) ; 1 Canterbury White Bine ' (density about 7) ; 

 'Cooper's White' (density =6 J-7) ; ' Fuggle's Hop ' (density =7); 'Old 

 Jones's Hop' (density=7-8). The term "golding" or "goldings " is gene- 

 rally applied by Hop merchants and factors to the best class of Hops such 

 as the ' Canterbury ' and ' Farnham Whitebines ' &c. The " density " of 

 a Hop, taken in conjunction with the shape of its bracts, is the best 

 means for distinguishing and classifying the different varieties. — B. N. 



Horse-chestnuts, jEscuIus and Pavia. By W. J. Bean (Gard. 

 Chron. No. 795, p. 187 ; figs. 57, 58, 59,and 60 ; 22/3/1902).— Descriptions 

 are given of nine species which are in cultivation, three of which are 

 figured. It is said that all the species are "noteworthy for their beauty 

 of foliage, standing perhaps pre-eminently in this respect as a genus of 

 hardy trees." All are gross feeders and like a rich moist soil. They are 

 beBl propagated from seed. The common Horse-chestnut is by far the 

 best a> a park or avenue tree, as none of the others in this country
